A leaking bathroom rarely announces itself in the bathroom. It shows up as a damp patch on the bedroom wall next door, or a stain on the ceiling of the flat below.
Bathrooms leak at the places where one thing meets another: the joint where the floor meets the wall, the seal around the floor trap, the point where a concealed pipe passes through the slab, and the area behind the shower that gets wet every day and never fully dries.
Once water is past the tiles it moves through the screed and into the masonry, and then it travels. That is why the damp patch usually appears in the next room rather than in the bathroom itself, and why treating the visible patch achieves nothing.
Tiles are not waterproofing. Grout is not waterproofing. The waterproof layer sits underneath both, and if it was never installed properly — or was skipped, which in older construction is common — no amount of resealing on top will hold.
We check the wet areas, the trap, the pipe routes and the wall on the other side, so that we are treating the actual leak rather than the place it happens to surface.
Where necessary, tiles and screed come up so we can treat the slab itself. Coating over existing tiles is a cosmetic fix, not a repair.
Floor-to-wall junctions, trap surrounds and pipe penetrations are sealed and reinforced first, because that is where the water is getting through.
A Sreechem wet-area system goes over the full floor and up the walls to the height that actually gets wet. Where practical we water-test before the tiling goes back, so problems surface now and not in six months.
Screed and tiling are restored and the bathroom goes back into use.
Doing this properly means the bathroom is out of use for a few days and the tiling in the wet area is disturbed. We will not pretend otherwise.
The alternative is repainting the damp wall each year while the water keeps working on the masonry and, eventually, on the reinforcement in the slab. One of these is a cost you pay once.
Where bathroom water has already tracked into a wall or a slab crack, injection treats it from within.
If the stain is on a top-floor ceiling, the terrace is the more likely culprit than the bathroom.
Ground-floor bathrooms over a basement need both problems looked at together.
We will come and look, tell you what is actually causing it, and quote only what it needs.
