Often it is not the plumbing
A bathroom is the one room where most water damage has nothing to do with pipes.
Grout and silicone are what keep shower water on the correct side of a wall. When they crack, perish or pull away at the base of an enclosure, every shower puts water into the structure behind the tile. The pipework stays perfectly dry, which is why inspecting it finds nothing.
The same applies below: a shower pan that has degraded, or a seal at the waste that has failed, sends water into the floor with no plumbing fault at all.
So the first job is not to trace pipes. It is to work out whether pipes are involved.
Test one fixture at a time
A bathroom has four possible sources within a few feet of each other, and using them together makes the result unreadable.
Run the basin alone. Then the bath. Then the shower, for long enough to matter, five minutes rather than thirty seconds. Then flush the toilet several times.
Between each, check where the damp appears and how quickly. A source that shows only after a long shower behaves differently from one that appears within seconds of a flush.
That sequence usually identifies the fixture before anyone opens a wall, and it is something you can do yourself before calling.
Does this sound familiar?
Problems this service solves
- Damp appearing in the room below a bathroom
- A toilet that rocks and leaves damp at its base
- Flooring lifting near a shower or bath
- Discoloured grout with damp behind the wall
- A persistent smell of damp with no visible water
Signs you need bathroom leak repair
If more than one of these is true, the problem is usually past the point a plunger or a store-bought cleaner will fix.
- Floor around the toilet is soft or discoloured
- Damp appears in the ceiling below only after showering
- Grout is cracked or missing at the base of the enclosure
- Skirting or flooring is lifting near a wet area
What to expect
How the visit works
Test each fixture separately
The bath, the shower, the basin and the toilet are used one at a time, because a bathroom has four possible sources and running them together tells you nothing.
Rule out the non-plumbing causes
Failed grout, a perished seal at the enclosure base and a degraded shower pan cause more bathroom damp than pipework does.
Check the toilet seal
A wax or rubber seal that has failed lets water past at floor level on every flush, which shows up as a soft floor and a rocking pan.
Repair the actual cause
Pipework is repaired, seals are renewed, and where the cause is the enclosure rather than the plumbing you get told that plainly.
What's included
What you get on every job, whoever we send.
- Fixtures tested individually to isolate the source
- Grout and seal failures identified rather than misdiagnosed as pipes
- Toilet seals checked, since they are a common hidden cause
- Honest answers when the fix is not a plumbing repair
Questions
Bathroom Leak Repair questions
My bathroom leaks but the pipes are dry. How?
Because a lot of bathroom water damage never touches a pipe. Grout and silicone at the base of a shower enclosure are what keep water on the right side of the wall, and once they crack or perish, every shower sends water into the structure behind. A degraded shower pan does the same beneath the floor. The pipework is fine, which is exactly why chasing it finds nothing, and the repair is a tiling or sealing job rather than a plumbing one.
The floor around my toilet is soft. Is that the toilet?
Almost certainly, and it is the seal at its base. That seal is what stops water and waste escaping between the pan and the drain flange, and when it fails, a small amount gets past on every flush. It goes straight into the subfloor, so there is nothing visible until the floor gives. A toilet that rocks slightly is both a cause and a symptom, because movement is what breaks the seal in the first place.
Should I just reseal everything to be safe?
Resealing what has actually failed is worthwhile. Sealing over everything is not, and it can make things worse. Silicone applied over damp or contaminated surfaces does not bond, so it looks sealed while water passes behind it, which delays finding the real problem. Worse, sealing the wrong edge of a shower tray can trap water inside the structure instead of letting it drain out. Find the failure, then seal that.
