Emergency plumber or leak specialist? Who to call for a ceiling leak
When water is dripping through a London ceiling, most people search for an emergency plumber - and if the cause is a burst pipe, that is the right instinct. The catch is that a plumber's job usually ends when the water stops. The stained, sagging ceiling, the soaked insulation above it and the damp plaster that will grow mould in a fortnight are all still yours.
We cover both halves of the problem. Our team responds to leak emergencies the way an emergency plumber does - available 24/7, water stopped first - and then traces the source properly, dries the fabric, and repairs the ceiling and decoration under one fixed quote. If it turns out the water is not plumbing at all (a roof defect, failed sealant in the bathroom above, or a neighbouring flat), you are already dealing with the right team rather than starting the call-out again from scratch.
If it is urgent: turn off the water at the stopcock, keep electrics well away from the wet area, and call us on 020 4571 7367.
Leaks we trace and repair
The visible damage is rarely where the leak is. Water travels along pipes, joists and cavities before it shows, so we trace first and open up second - one targeted repair instead of exploratory holes in your ceiling.
Plumbing leaks
Failed pipe joints, pinhole leaks in copper, leaking waste pipes and appliance connections - traced, isolated and repaired.
Bathroom leaks
Failed silicone and grout, leaking shower trays and hidden leaks behind tiled walls - the classic source of a stain on the ceiling below.
Radiator and heating leaks
Weeping valves, corroded radiators and heating pipework under floors - found and fixed with minimal disruption.
Roof and gutter leaks
Slipped tiles, failed flashing, blocked or broken gutters letting water into the fabric - repaired at the defect, outside in.
Leaks from the flat above
A London speciality. We document the source and the damage - evidence you or your managing agent can use - then repair your side properly.
Overflow and tank leaks
Overflowing cisterns, cold-water tanks and blocked overflow pipes staining walls and ceilings below.
Smaller plumbing job, like a dripping tap or a running toilet? Our small plumbing repairs team handles those at a fixed price.
Ceiling water damage repair
A brown stain, sagging plasterboard or a bulge in the paint means water has been sitting above your ceiling - and painting over it never works. The repair has to happen in the right order: stop the leak, dry the void above, then replace or replaster what the water ruined.
- 1Trace and stop the leak - plumbing, bathroom above, roof or a neighbouring flat.
- 2Dry the ceiling void and check the joists and wiring the water ran across.
- 3Cut out and replace sagging or stained plasterboard; replaster where the board is sound.
- 4Stain-block, repaint and match the finish - so there is no shadow of the leak left.
- 5Check for mould that grew while the fabric was wet, and treat it professionally if found.
One team does all of it - the leak, the drying, the plastering and the decorating - with a fixed quote up front and our 12-month guarantee on the lot.

Why London properties leak the way they do
London's housing makes leaks both more common and harder to trace. Victorian terraces carry a century of patched plumbing and shared rainwater goods; flat conversions stack bathrooms above living rooms with the pipework squeezed into old floor voids; and purpose-built blocks mean a leak in one flat surfaces two floors down. Add flat roofs on rear additions and original parapet gutters, and water has plenty of hidden routes into your home.
That is why tracing matters more than anything in this city - and why an unrepaired leak so often turns into a damp and mould problem. If a slow leak has already left damp walls behind, our free London damp survey maps how far the moisture has spread, and our mould removal team deals with anything that grew in the meantime. Landlords: leaks reported by tenants now sit inside strict damp-and-mould timescales - see our guide to Awaab's Law for private landlords.

Frequently asked questions
- How quickly can you get to a leak in London?
- We are available 24/7 for emergencies and respond across London within 24-48 hours for non-urgent leaks - usually much faster when water is actively coming through. Call us first if water is near electrics, and turn off the supply at the stopcock while you wait.
- Can you find a leak if I do not know where it is coming from?
- Yes - tracing hidden leaks is most of the job. Water travels along joists, pipes and cavities before it shows, so the stain on your ceiling is often nowhere near the source. We trace the leak to its origin before opening anything up, so the repair is one targeted fix rather than exploratory holes.
- Do you repair the ceiling and walls after fixing the leak?
- Yes. We are a maintenance company, not just a leak-detection service: the same team fixes the leak, dries the affected area, replaces or replasters damaged plasterboard, and repaints to match - one job, one fixed quote, one 12-month guarantee.
- How much does leak repair cost in London?
- It depends on where the leak is and what it has damaged, so we quote fixed after seeing it - free assessment, no call-out charge, and the price in writing before work starts. Send a photo or video on WhatsApp for the fastest initial view.
- The leak has caused mould - can you deal with that too?
- Yes. A leak that has been running for weeks almost always leaves damp plaster and mould behind. We fix the leak, dry the fabric, treat any mould professionally and refinish the surfaces - all covered by the same unconditional 12-month guarantee.
