Plumber in Dammam – Plumbing Rough-In, Re-Piping, Bathrooms, Heaters & Pumps

Plumber in Dammam: Aemar Al-Maryam General Contracting sends a plumbing crew for rough-in for new buildings, villas and annexes, water supply and drainage lines, re-piping of older homes, bathroom and kitchen plumbing, and the installation of water heaters, pumps and tank connections, on an appointment set after an inspection or after we review the photos you send on WhatsApp. Bathroom rough-in starts from SAR 460, a kitchen from SAR 135, new-build rough-in from SAR 23 per square metre, a water heater from SAR 140 and a pump from SAR 275, all labour estimates until inspection and agreement. For a small fault, send a photo and we will tell you whether one visit will cover it. Phone and WhatsApp: 0547879578.

Water moves through a house in two networks that nobody sees once the tiles are down. One is a pressurised supply network that brings cold and hot water to every tap; the other is a gravity drainage network that carries used water to the inspection chambers and on to the city sewer. Almost every problem that shows up later, from a damp patch on the living-room ceiling to a smell in the bathroom or weak pressure upstairs, goes back to a decision made at rough-in: a pipe size, the fall of a drain, a joint that was never tested, a valve buried behind tiles. This guide explains how we build both networks in Dammam, the materials and figures we work to, what each item costs, and how to order the work and compare quotes.

Plumber in Dammam: what we do and how to book

We carry out plumbing in Dammam on a fixed appointment. You send photos or we inspect the site; we define the work, the materials, the number of days and the estimated cost; then the plumbing crew arrives on the agreed day with fusion and testing tools. That suits planned work: a bathroom being redone, old pipes that keep leaking, a new heater, or an annex that needs a full network.

We say it plainly because many adverts say the opposite: we are not an emergency call-out that turns up within minutes at any hour of the night. We are a contracting establishment with plumbing crews that work on scheduled jobs, which is exactly why we can give you an itemised quote, follow the drawings and test the network before it is closed. If you have a small fault, such as a dripping mixer, a running cistern or a pipe under the basin, send a photo. We handle it during a scheduled visit or alongside other work in the house, and we tell you honestly if it is worth a visit of its own.

Plumbing technician or master plumber in Dammam: who comes to your house?

The person who comes is a plumbing technician or master plumber from our crew, depending on the size of the job. A master plumber leads rough-in and full re-piping work, reads the drawings and decides the routes; one or more technicians handle fusion, fixing, connections and testing. On larger jobs a supervisor coordinates with the other trades: chasing before us, electrics and AC alongside, waterproofing, plaster and tiles after.

Plumber phone number in Dammam: what happens after you call?

When you call or message 0547879578 we ask what kind of work it is, then ask for photos of the area, the number of bathrooms and kitchens, the floor and the age of the house. For work that is clear from photos we send an estimated cost; for work that needs measuring and seeing, we book an inspection. Then the items follow in writing on WhatsApp: scope, materials, who buys them, duration and exclusions.

Plumbing company or hourly plumber in Dammam? When you need a plumbing contractor

You need a plumbing company or contractor in Dammam when the work covers more than a single point, when walls or floors have to be opened, or when the work must be tested before it is covered. A single visible fault, such as changing a mixer tap or clearing a basin, is fine for one plumber. The difference is who answers for the result once the wall is closed.

What matters to you in practice is that a plumbing contractor writes clear items: the pipe type and its pressure class, the number of points, the test method and how long it is held, and who re-plasters the chases afterwards. Those items are what make a SAR 3,000 quote comparable with a SAR 5,000 one; a checklist of questions follows later in this guide.

Plumbing rough-in in Dammam for new buildings, villas and annexes

Plumbing rough-in in Dammam means running the supply and drainage networks inside walls, floors and ceilings before plaster and tiles, fixing the outlet for every sanitary fitting at its correct position and height, and then testing both networks before they are closed. It happens after the structure and blockwork and before finishing, and it follows the approved plumbing drawing where there is one, or a layout we prepare with you for small houses and annexes.

Our rough-in scope includes: routing the main line from the roof tank to each floor; an accessible main valve plus an isolation valve for every bathroom and kitchen; cold and hot lines sized to the number of fixtures; drainage from each fixture to the vertical stacks and on to the inspection chambers at correct falls; vent lines; AC condensate drains; and fixing concealed mixer bodies and concealed cistern frames before tiling. Then we test, photograph the routes and hand you the photos.

When does plumbing rough-in happen? Sequencing with electrics, plaster and tiles

Getting the order of trades right saves you from breaking the same wall twice. The common mistake is letting the plasterer start before plumbing and electrics are finished, so the walls get opened again. The sequence we work to:

1. 1
   Structure and blockwork
   Walls are complete, and fixture positions are marked on the floor and walls.
2. 2
   Slab penetrations
   Holes for stacks and drains are formed before the pour, or cored afterwards; on a cast slab we arrange them through core drilling in Dammam.
3. 3
   Wall chases
   Straight chases are cut in the blockwork, deep enough for plaster to cover the pipes.
4. 4
   Plumbing and electrics together
   We run supply and drainage in coordination with the electrical crew so cables never share a route with hot-water pipes. Electrical rough-in is handled under our electrical works service.
5. 5
   Testing and photographs
   Pressure test on supply, water test on drainage, then every wall is photographed before closing.
6. 6
   Closing chases and plastering
   Chases are filled with mortar, with mesh where needed, and then plastering begins.
7. 7
   Waterproofing and tiles
   Bathroom and kitchen floors are waterproofed with the membrane turned up the walls, then tiled, then fixtures are fitted.

Villa plumbing in Dammam

A villa differs from an apartment in three ways: the number of floors, the number of bathrooms, and the presence of an underground tank, a roof tank and a pump. So we start a villa by working out the demand: how many bathrooms on each floor, where the main and the preparation kitchens are, whether there is a basin in the majlis, and whether you want one central heater or a heater per bathroom. From that come the main pipe sizes and the stack positions, which we try to keep in a single wall where possible so that drainage runs are short and joints are few.

In villas we follow what MOMAH’s residential building requirements set out: water piping to the Saudi plumbing code, drainage to the separate sanitary drainage code, and the ground floor’s drainage connected to the main line separately from the upper-floor stacks. That last rule sounds like a detail, but it prevents waste from the floors above backing up into ground-floor fixtures when the external line is blocked.

Annex and majlis plumbing in Dammam

A new annex on the roof or in the courtyard needs a small but complete network: a bathroom and perhaps a preparation kitchen, a water source from the roof tank or a floor line, and a drain that reaches the nearest stack or inspection chamber at a proper fall. We plan that network from the start when we carry out annex and majlis construction in Dammam, and we price it per bathroom and kitchen or per square metre. If the annex is on the roof, we decide before starting where the drainage will pass through the slab, and whether a new hole has to be cored.

Water supply lines in Dammam: pipes, sizes and valves

Water supply lines in Dammam are the pressurised network that carries water from the roof tank or pump to every tap, with separate cold and hot lines. We mostly install them in PPR pipe joined by heat fusion, so that the fitting and the pipe become one piece that does not depend on rubber rings or solvent cement.

PPR fusion uses a welding tool that heats the pipe and the fitting together at about 260 °C (plus or minus 10 °C) for a few seconds that vary with diameter: roughly 5 seconds for 20 mm, 7 seconds for 25 mm and 8 seconds for 32 mm. The pipe is then pushed in straight, without twisting, and left to cool. Overheating chars the joint, and twisting during insertion tears the fused layer inside. Neither is visible to the eye, but both show up in the pressure test, or months later behind the tiles.

The sizes in the table are common in homes, not a fixed rule; the right size is calculated from the number of fixtures on the line, its length and its height below the tank. One thing we always allow for is that PPR expands noticeably with heat: a 10-metre hot line can grow by six centimetres or more if its temperature rises by 40 degrees. So we fix it with clips that let it move and build in offsets that absorb the expansion, instead of letting the line bow or push against the joints.

Manifold or branch-and-tee distribution?

With branch-and-tee distribution, one line passes the fixtures in turn and each point is taken off with a tee. With a manifold, a single box sends a separate line to each fixture, so there are no joints inside the wall between the manifold and the fixture, and one fixture can be isolated without cutting water to the whole bathroom. A manifold costs a little more in fittings and uses more pipe, but it reduces hidden joints, which are the places most likely to leak. We suggest it for main bathrooms and new villas, and we leave the choice to you once we have explained the price difference.

Drainage in Dammam: pipe sizes, falls and venting

Drainage in Dammam is a gravity system, so pressure does nothing for it; what it needs is the right fall, the right size and proper venting. We install it in uPVC, and we work from the external inspection chamber upwards to each fixture so that the fall is continuous with no back-falls.

The fall follows the Saudi plumbing code, which is based on the International Plumbing Code: not less than 2% for small pipes up to about 75 mm, that is two centimetres per metre, and about 1% for pipes from 110 mm to 160 mm, one centimetre per metre, always subject to the drawings. A steeper fall is not better, as many people assume. On short branches a very steep fall lets water outrun the solids and leave them stuck to the pipe, and that is where a blockage begins.

Venting: why does the basin pull water out of the trap?

Every sanitary fitting has a trap that holds a little water to stop sewer gas. When water rushes down an unvented drain, it drags air behind it from the nearest trap and empties it, so you hear gurgling and then smell the drain. That is why we run vent pipes that connect the network to outside air above the roof and tie the fixture branches into them as the drawings require. Where a vent cannot be added in an existing house, we explain the alternatives and their limits first.

Inspection chambers and cleanouts

An inspection chamber is an access point where the external line changes direction or two lines meet, and it lets the line be cleaned without breaking anything. We build new chambers or replace damaged ones, starting from SAR 185 per chamber, with a tight cover and the correct invert level. In Dammam we treat anything buried in the ground with care, because groundwater sits close to the surface in much of the Eastern Province, and its salts attack concrete and steel; chambers are waterproofed and built from materials suited to those conditions.

Suspended drainage in Dammam: what it is and when it is the better choice

Suspended drainage in Dammam means running the upper floor’s drainage under the ceiling of the floor below, hung on metal hangers at a steady fall and then hidden by a gypsum false ceiling, instead of burying the pipes in the bathroom floor fill. Its first advantage is that a leak shows up in the false ceiling and can be fixed through an access panel without breaking the bathroom tiles.

It comes with conditions. The ceiling must be high enough to leave a comfortable height once the false ceiling is fitted; hangers must be fixed at regular spacing so the pipe does not sag and lose its fall; access panels must be left at joints and bends; and the pipes must pass through the slab in clean holes. In an existing house we core the slab rather than break it, then close the ceiling as part of gypsum board installation.

We do not recommend suspended drainage everywhere. On the ground floor, for example, there is no ceiling below, so drainage stays in the floor and runs to the inspection chambers. Converting an existing bathroom to suspended drainage is priced on inspection, because the work varies with ceiling height, the tiling above and the condition of the slab.

Bathroom plumbing in Dammam and bathroom plumbing finishing

Bathroom plumbing in Dammam covers the cold and hot lines to every fixture, drainage for the WC, basin, shower or bath and floor drain, and the concealed mixer body and concealed cistern frame if you choose them, all done before waterproofing and tiling. Bathroom plumbing finishing is the last stage after tiling: fitting the WC, basin, mixers, bidet spray and accessories and checking every point. Rough-in for a standard bathroom starts from SAR 460 in labour.

Concealed mixers and concealed cisterns: what goes in before the tiles

A concealed mixer has a body buried in the wall and a trim plate fitted after tiling; a concealed cistern is a tank inside a steel frame behind the wall, with only the flush plate showing. The rule for both is the same: they are fixed at the correct depth and height before tiling, allowing for the thickness of tile and adhesive, because any mistake after tiling means breaking tiles. We run water through the mixer and the cistern during the network test, and we leave the cistern access opening where the manufacturer specifies.

Outlet heights in a bathroom

There is no single mandatory set of heights, because fixtures differ from model to model; the reliable source is the instruction sheet of the fixture you have chosen, read before rough-in, not after. That is why we ask you to choose the basin, WC and mixers early, or at least their type (wall-hung or floor-standing, concealed or exposed), and then set the outlets accordingly:

More important than height are three things often missed: hot on the left and cold on the right, as everyone expects; the floor drain at the lowest point of the floor, not above it; and the floor waterproofed, with the membrane turned up the walls, before tiling. Waterproofing is done by or coordinated with our roof and bathroom waterproofing team in Dammam, and tiling comes after it with our tile installer in Dammam, so the tile falls lead to the drain we positioned.

Bathroom plumbing finishing in Dammam: the final fit-out

After tiling we return to fit the fixtures: the WC with a new seal, fixed to the floor or its frame; the basin and its mixer, from SAR 90; mixer taps from SAR 75 each; the bidet spray and angle valves. Then we run every point and watch the joints under the basin and behind the WC, and we check that water flows to the floor drain without ponding. If you want the whole bathroom renewed, from demolition to tiles and fixtures, look at our bathroom and kitchen renovation service, where a complete bathroom renovation starts from SAR 2,300 and plumbing is one part of it.

Kitchen plumbing in Dammam

Kitchen plumbing rough-in in Dammam covers hot and cold supply to the sink, a point for the dishwasher, a point for a water filter if you want one, and a 40 mm waste from each with a good fall. It starts from SAR 135 in labour, which is less than a bathroom because a kitchen has fewer points and no 110 mm WC drain.

What matters most in a kitchen is that the points match the cabinet design: the sink position, the width of the dishwasher bay, and the fridge position if it needs water. So we ask for the kitchen layout or cabinet dimensions before running anything, and we leave the points where drawers will not foul them. Grease is what blocks kitchen drains most often, so we give the line a good fall and place a cleanout somewhere reachable. If you are renewing the whole kitchen, cabinets, services and tiles, see our bathroom and kitchen refit service or our Dammam renovation work.

• ✓Washing machine: a valved supply point and a trapped standpipe waste, ideally in the laundry room rather than the kitchen.
• ✓Water filter: a separate valved cold point under the sink, so the filter can be changed without cutting water to the sink.
• ✓Annex or preparation kitchen: the same items at smaller sizes, and we check that its waste reaches a stack or inspection chamber at a proper fall.

Re-piping older homes in Dammam: when it is needed and how we do it

Re-piping a house in Dammam means replacing the old supply network, usually galvanised steel in older homes, with a new PPR network, and it may include drainage if the old pipes are cracked or the wrong size. It becomes necessary when scattered repairs cost more than replacement, when the water runs brown, or when pressure is weak throughout the house.

Signs that the pipes in your house have reached the end of their life

• ✓Repeated leaks in different places: each repair exposes a weakness somewhere else, so the problem is the network, not one point.
• ✓Brown or rusty water when a tap is first opened: a sign of corrosion inside galvanised steel, which also narrows the bore.
• ✓Weak pressure at every tap: once the pump and tank are ruled out, the cause is scale inside old pipes.
• ✓A meter that moves with every tap closed: a hidden leak that needs detecting before anything is broken.
• ✓Renewing every bathroom and the kitchen: if the tiles are coming off anyway, re-piping at the same time costs less than coming back later.

Can pipes be replaced without breaking walls?

Partly, yes. Supply lines can sometimes run along neat exposed routes inside cupboards or above a false ceiling and drop down to the points, and upper-floor drainage can be converted to suspended drainage under the ceiling instead of breaking floors. But points inside tiled walls still need opening along their route. The difference is that we cut a defined chase with a saw rather than breaking at random, and close it after testing. We estimate with you how much tiling will be opened before we start, so you can decide whether to retile the whole wall or just make good the opened strips.

Replacing a damaged section of pipe starts from SAR 165 per section or point, while replacing a house’s entire network or converting it to suspended drainage is priced on inspection: the bathroom count, run lengths and the amount of tiling to open all change it. When re-piping is part of a wider renovation we coordinate it with the renovation contractor in Dammam, and breaking out with our demolition contractor in Dammam, so no wall is opened twice.

Water heater installation in Dammam: electric and central

Our water heater installation in Dammam includes fixing the heater on brackets that carry its full weight, connecting the cold inlet and hot outlet with valves, fitting a temperature and pressure relief valve with a discharge pipe to a safe place, then commissioning and checking. Installing an electric storage heater starts from SAR 140 in labour; a central heater with a return and circulation line is priced on inspection.

The relief valve is not an optional extra. The plumbing code requires safety devices on water heaters, and the valve’s job is to open if the temperature or pressure inside the tank rises beyond its limit, releasing water through the discharge pipe instead of letting the tank fail. That is why we route its discharge to a drain or somewhere it cannot hurt anyone, and we never plug it or run its pipe upwards.

What temperature should you set the heater to?

International health guidance recommends storing hot water at 60 °C or above to limit the growth of Legionella bacteria, and delivering it so that taps reach about 50 °C within a minute of opening. Cold water is best kept below 20 °C where possible. But water above 44 °C starts to scald children and elderly people, so we fit a thermostatic mixing valve on the line to the bathroom they use: the tank stays hot, and the water reaches the skin at a safe temperature.

Water pumps and low water pressure in Dammam

Water pump installation in Dammam usually takes one of two forms: a transfer pump that lifts water from the underground tank to the roof tank, after which the house runs by gravity, or a booster pump with a small pressure vessel and a switch that starts it when a tap opens. Installing and connecting a pump starts from SAR 275 in labour, and the pump itself is priced separately.

We mount the pump on a solid base that stops vibration, with a valve on the suction side and one on the delivery side, a non-return valve that stops water running back to the tank, and a pressure gauge so you can read its condition. We shade it from direct sun where possible and confirm its electrical supply suits its rating. We set the pressure switch to a value that suits the house and no higher, because excess pressure strains joints and mixers.

Low water pressure in Dammam: where to start the diagnosis

Low pressure is one complaint with many causes, so we check it in an order that starts with the simplest. Diagnosing and fixing low pressure starts from SAR 135 per visit; anything that needs parts or new lines is added after agreement.

1. 1
   Whole house or one point?
   One point usually means a blocked mixer aerator or a half-closed angle valve.
2. 2
   Only on the upper floor?
   The roof tank may not sit high enough above the top floor; the answer is a small booster pump.
3. 3
   Tank and float valve
   A tank that never fills or a stuck float gives intermittent pressure.
4. 4
   Pump and pressure switch
   We read the gauge, watch it cut in and out, and check the non-return valve.
5. 5
   Pipe sizes and valves
   An undersized main or a main valve not fully open, the simplest cause and the one most often forgotten.
6. 6
   Old pipework
   If everything above is ruled out, scale inside old steel is the cause, and the cure is replacing the sections.

Water tanks in Dammam: underground, roof and their connections

Most houses in Dammam have two water tanks: an underground tank filled from the water network, and a roof tank fed by the pump that supplies the house. We connect or install a roof tank starting from SAR 920, and we connect the underground tank to the pump and the network; building a new underground tank, with excavation, casting and waterproofing, is priced on inspection.

For tanks we follow the residential building requirements: the two tanks together should hold at least five days of the occupants’ needs, tanks must be tightly waterproofed inside and out, and the distance between the water tank and the septic tank must not be less than one metre. That last rule matters in older houses still on septic tanks, where a leak can contaminate a nearby water tank unnoticed.

• ✓Fill connection: from the meter to the underground tank, through a float valve that closes when full.
• ✓Overflow and vent: an overflow pipe with an insect screen, and a covered vent.
• ✓Lid: tight, and raised above the ground or roof level so washing water and rain cannot get in.
• ✓Drain valve: to empty the tank for cleaning without a pump.
• ✓Lining: a drinking-water-safe lining, coordinated with the tank section of our waterproofing guide.

The water reaching Dammam homes from the public network is desalinated and operated by the National Water Company, and the Saudi Water Authority has announced expanded desalination capacity in the Eastern Province serving Dammam, Al Khobar, Dhahran, Qatif, Saihat, Al-Ahsa, Ras Tanura and Safwa. So the cleanliness of your water after the meter depends on your own tank and pipes, not on the source.

Leak detection in Dammam: the short version

Leak detection in Dammam locates a leak before anything is broken, starting with a meter test and moving on to instruments. You can begin yourself: close every tap, the heaters and the pump, then watch the meter for ten minutes; if it moves, there is a leak in the network after the meter. A bill that suddenly jumps, damp patches on walls and ceilings, and floor tiles that lift or whose joints change are other signs.

Instrument-based detection (thermal camera, moisture meters and pressure testing), its details and its prices are covered in the leak-detection section of our roof waterproofing and leak detection guide for Dammam. Our plumbing role starts once the location is known: we open only at that point, repair the joint or replace the section, and test it before closing. If the leak left stains on a wall or ceiling, putting them right is a job for our painting contractor in Dammam; if damp has caused cracking, see crack repair in Dammam.

Drain blockages and sewer smells in Dammam

Most drainage problems in Dammam come down to one of four causes: the wrong fall, grease and deposits in the kitchen line, a dry or missing trap, or a broken pipe under the floor. We clear basin and floor-drain blockages from SAR 90 per visit, but what matters more to us is finding out why the blockage keeps returning, because repeated clearing treats the symptom, not the cause.

Sewer smell in the bathroom: where does it come from?

• ✓An unused floor drain: the trap dries out and the smell rises; pour a little water into it every week.
• ✓The WC seal: if the seal between the WC and the drain fails, the smell escapes at the base.
• ✓No venting: the drain siphons the traps, so the gurgling and the smell keep coming back.
• ✓A waste with no trap: in some older houses the drain connects straight to the line; the fix is fitting a trap.
• ✓A broken pipe: a constant smell together with damp in the wall or the ceiling below the bathroom.

We fix the cause rather than masking the smell. If back-ups keep happening on the ground floor in particular, we check whether its drainage is tied into the main stack with the upper floors, which the requirements prohibit; the cure is to separate the ground-floor line and run it straight to the inspection chamber.

Plumbing pressure test and drainage test in Dammam before closing the walls

A plumbing pressure test in Dammam is a step we never skip before closing a wall: we fill the supply lines with water, raise the pressure with a hand test pump to a value above working pressure according to the pipe manufacturer’s instructions, and watch the gauge. We test drainage by filling it with water to a column of at least 3 metres for at least 15 minutes, as the Saudi plumbing code requires.

The Saudi plumbing code requires the supply network to prove tight under water pressure no lower than the system’s working pressure, and it allows drainage to be air-tested at 35 kPa for 15 minutes instead of the water column. On PPR lines we go beyond the minimum, following what pipe makers recommend: a pressure above working pressure (one and a half times working pressure is often quoted), raised in stages, with air bled from the highest points, then the line left to stabilise and watched. Any drop in the reading means we find the joint and remake it before tiles cover it.

1. 1
   Cap the outlets
   Every line end is sealed with a test plug.
2. 2
   Fill and bleed
   The line is filled slowly and the highest outlet opened until all the air is out.
3. 3
   Raise the pressure in stages
   With the hand pump, up to the test value set for the pipe.
4. 4
   Watch and record
   We note the reading at the start and after the stabilising period, and look at every joint.
5. 5
   Drainage test
   Plug the lowest outlet, fill the line to a 3-metre column of water and watch it for at least 15 minutes.
6. 6
   Photograph, then close
   We photograph the wall, the lines and the gauge reading, then allow the chases to be closed.

The plumbing materials we use in Dammam

For supply we mostly use PPR pipe, for drainage uPVC, and we suggest alternatives when there is a reason to. We do not name a particular manufacturer; we set the specification and pressure class, and you choose from compliant products on the market, or we supply them as part of the quoted items.

Among the mistakes we see in houses: PPR used for drainage, fittings from more than one system mixed in the same network, and a pipe rated for cold water used on the hot line. That is why our quote states the material and pressure class for each line, so you know exactly what you are paying for.

How plumbing work is carried out in Dammam, step by step

Our plumbing jobs follow the same steps whether it is one bathroom or a whole villa; only the size of each step changes:

1. 1
   Photos or inspection
   You send photos and drawings on WhatsApp, or we visit to measure.
2. 2
   Items and estimated cost
   We send exactly what we will do: points, materials, testing, and who re-plasters.
3. 3
   Agreeing materials and dates
   You choose the materials or we supply them, and we fix the start date and duration.
4. 4
   Setting out
   We mark routes and outlet positions on the walls and review them with you.
5. 5
   Chases and penetrations
   We cut chases and form slab holes by coring or saw cutting as needed.
6. 6
   Pipework and fusion
   We run supply, drainage and vents, and fix mixer bodies and cistern frames.
7. 7
   Testing and photographs
   Pressure and drainage tests, then every wall photographed.
8. 8
   Closing and handover to the next trade
   Chases closed, ready for waterproofing, plaster and tiles.
9. 9
   Final fit-out
   After tiling we fit the fixtures, run every point and hand over.

In occupied homes, water is shut off only for agreed hours, floors and nearby furniture are covered, and debris leaves daily. Rough-in for a single bathroom typically takes one to two days for chases, pipework and testing, after which waterproofing and tiling follow; the final duration is set after inspection.

Plumbing prices in Dammam: our “starts from” table

Our plumbing prices in Dammam are labour rates that start from the figures below, with pipes and fittings of your choice unless stated otherwise. Each is provisional pending a site visit and agreement; the final figure comes from the site visit or the drawings and reflects points, run lengths, floor and access.

Items marked “on inspection” carry no figure because they vary too much from one house to another; a WhatsApp message to 0547879578 with photos and dimensions lets us work out an estimated cost. For large jobs we set the price after an inspection or from the drawings. For rates across our other trades, open the prices page.

What pushes plumbing costs up or down?

• ✓Number of points: each supply or drainage outlet is an item, so a main bathroom with more fixtures costs more than a guest bathroom.
• ✓Distances: a bathroom far from the main stack needs longer lines and harder falls.
• ✓Floor and access: carrying materials to an upper floor without a lift, or working at a high ceiling, takes longer.
• ✓New or existing: rough-in in a shell building is faster than opening tiled walls in an occupied house.
• ✓Materials: pipe type and pressure class, a manifold instead of tees, and the type of mixers and cisterns.
• ✓Grouping: a single trip covering several items costs less per item than separate trips.

Worked example: re-plumbing a three-bathroom house in Dammam

An illustrative example: a house with three bathrooms and a kitchen, whose owner wants the bathroom and kitchen plumbing redone, plus a new electric heater and a booster pump:

That figure is labour only. It excludes the pipes, fittings, heater and pump, the bathroom floor waterproofing (from SAR 26 per square metre in our waterproofing guide), and any breaking out, re-plastering and tiling, which are priced on inspection. If the building were a new 300 m² shell, the calculation would be per square metre instead: 300 × 23 = SAR 6,900 in rough-in labour before materials. These numbers are for illustration; the actual cost is set after inspection and agreement.

Plumbing mistakes we keep finding in Dammam homes, and our fix for each

Most of what we are called in to fix in existing homes comes from rough-in mistakes that a few extra minutes would have prevented. These are the ones we see most, and what we do to avoid them:

Choosing a plumbing contractor in Dammam: what the quote should say

Choose a plumbing contractor in Dammam by what he writes down before he starts, not by what the advert promises. A good quote breaks down the items and names the materials and the test; a weak one is a single large figure with no detail. Put these questions to anyone you are considering and compare the answers:

Do not let the lowest price be the only test. The difference between two quotes is usually an item missing from the cheaper one: the test, the re-plastering or the valves. Ask to see previous work too; some of ours is on the projects page.

Plumbing as part of renovation and finishing in Dammam

Plumbing inside a bigger project costs less when it runs with the other trades on one programme: re-piping before new plaster, rough-in before waterproofing and tiles, an annex network planned with the build. Related services:

The plumbing works page summarises the service, and combined bathroom and kitchen refits are under bathroom and kitchen renovation.

Plumber in Al Khobar and Dhahran, plus Qatif and other towns in the region

We carry out plumbing outside Dammam the same way: an appointment after photos or an inspection, and a crew travelling from Dammam with fusion and testing equipment. The request we receive most often outside Dammam is for a plumber in Al Khobar, followed by Dhahran, because they are close by and their buildings are much like Dammam’s.

Plumber in Al Khobar and Dhahran

In Al Khobar we carry out rough-in, re-piping, bathroom plumbing and water heaters in flats and villas, in districts including Al Thuqbah, Al Olaya, Al Aqrabiyah, South Khobar, the Green Belt, Al Hada and Madinat Al Ummal. In Dhahran we do the same work for villas and houses. Our prices in both cities are the same as in Dammam, and we group nearby jobs into one visit. If the plumbing is part of a house renovation in Al Khobar, see the renovation contractor in Al Khobar.

Qatif, Saihat, Jubail, Al-Ahsa and other towns

Our crews also reach Saihat next to Dammam and Qatif; northwards Ras Tanura, Jubail and Khafji; and south and west Abqaiq and Al-Ahsa, along with Hafr Al-Batin. For distant towns, travel is priced at inspection, and combining jobs on one trip brings the per-item cost down. In Jubail Industrial City, water and sewerage services are run by Marafiq, so any new connection to the public network there goes through it; in Dammam and the surrounding cities it goes through the National Water Company.

Dammam districts we cover for plumbing

We are based in Al Rawdah district in Dammam, and from there we reach both the older districts and the newer schemes, including:

The list gives examples rather than limits; we reach any district inside Dammam, so share your location pin in a WhatsApp message and we will arrange the visit. Coverage details are on the Dammam area page.

What to send on WhatsApp for a plumbing estimate

The clearer your photos and details, the closer the estimate will be to the final cost, and for small jobs they may save an inspection visit altogether. Send to 0547879578:

• ✓Photos of the space: a wide shot of the bathroom, kitchen or wall, and a close-up of the fault or pipe.
• ✓Drawings or dimensions: the plumbing or architectural drawing if you have it, or rough room measurements.
• ✓How many: the number of bathrooms and kitchens the work covers.
• ✓Floor and building age: and whether the house is occupied or a shell.
• ✓Existing pipe type: if you know it, or a photo of an exposed pipe.
• ✓What you need: rough-in, re-piping, a heater, a pump, a tank, or a specific fault.
• ✓Location: your district or a map pin.
