Leak Detection & Repair in Fulham

Modern tracing combines several non-invasive methods. An acoustic listening device picks up the sound of escaping water in pipes, a moisture meter maps damp in walls and floors, a thermal imaging camera shows warm patches from a leaking heating pipe, and pressure tests isolate which section of a circuit is losing water. The partner then opens the floor or wall only at the point the evidence indicates. That keeps the damage to a small, tidy hole rather than a trench.

With every tap closed and no appliance running, a moving meter indicates a leak somewhere between the meter and your fittings. It may be inside the house, under a floor or in the underground supply pipe from the boundary. Closing the stopcock and watching the meter will tell you whether the leak is before or after it. The partner can pinpoint which section, and tell you whether Thames Water or you are responsible for repairing it.

A leak tends to produce a patch that stays or grows regardless of the weather, may feel cold and wet to the touch, and may discolour plaster with a brown tide-mark. Condensation shows as water droplets and black mould in cold corners, worse in winter and in poorly ventilated rooms. If the patch is under a bathroom, radiator or kitchen, or appears after you have used water, a leak is likelier. A partner can test with a moisture meter.

Generally, whoever's pipe or fitting caused the leak is responsible for repairing it and may be liable for damage, but responsibility depends on your lease and the cause. If the leak is from a shared pipe or from the building's structure, the freeholder or managing agent may be responsible. Tell your managing agent promptly, take dated photographs, stop the leak where you can, and notify your own insurer. A partner plumber's written note on the cause can be very useful.

They can be. Houses built before the middle of the twentieth century, which includes most of Fulham's Victorian stock, may still have lead supply pipes, particularly where the plumbing has never been fully renewed. Lead pipes are prone to developing leaks at joints and are generally recommended for replacement, which a partner can quote. If you are concerned about water quality, Thames Water can advise on testing, and replacing the lead run with copper or plastic is the permanent answer.

There is no single price because it depends on access and method, but published 2026 London call-out fees run from about £80 to £150 in the daytime, with hourly rates of £60 to £80 after the first hour. A concealed burst pipe behind a wall typically totals £300 to £600 including repair, whereas an accessible leaking joint is about £150 to £300. The partner will give you a written quote after the diagnosis, and you should compare it with those ranges.

Only if necessary, and only after the leak has been located as accurately as possible. In many cases a section of floorboard can be lifted and replaced, or a small inspection hole made in a plasterboard wall and filled afterwards. In a plaster-and-lath Victorian ceiling, the partner will try to limit the opening. Making good, such as re-plastering and decorating, is normally quoted separately, so ask what the quote includes.

A slow drip into a bowl is usually fine to leave until daytime, as long as you check the bowl regularly and keep the area away from electrics. A leak that is getting worse, running into a ceiling, or near sockets and light fittings is not. If the leak is from a heating pipe, turn the boiler off and shut the nearest isolation valve. We will tell you on the call whether it can wait.

The usual suspects are a buried joint under a floor, a leaking pump seal, a weeping radiator valve that evaporates quickly, a pressure relief valve that is discharging through an external pipe, or an expansion vessel that has lost its air charge. Because the water may leave slowly or out of sight, a pressure test and thermal imaging are used to find it. Topping up repeatedly without finding the leak risks corrosion and a more serious failure.

Yes. We cover Fulham, Parsons Green, West Kensington, West Brompton, Sands End and Imperial Wharf, and each has different building types and problems. Riverside apartments at Imperial Wharf have modern pressurised systems, while the older streets have Victorian pipework. Give us your postcode and whether you are in a house or flat, and we will send a partner who has the right experience.
