Plumbers & electricians in Brixton

The district runs uphill. It starts at the town hall and the Ritzy, climbs Brixton Hill past the surviving fenced strips of Rush Common, and tops out at Streatham Hill, while Tulse Hill runs off east toward Brockwell Park. The higher ground carries the bigger houses, semi detached and detached villas behind front gardens. Lower down the terraces tighten up to three and four storeys, a great many with a lower ground floor.

Almost none of it is lived in the way it was built. A house that once had a single bathroom over the stairs now holds three or four flats, and each of them wanted a bathroom of its own, then later a second shower room in a box room or the end of a bedroom. Between the terraces sit the mansion blocks on the main roads and the estates behind them, Tulse Hill among them. The same density shapes the rest of the work: a blocked drain in Brixton is often shared before it is anyone’s alone, four kitchens feeding one gully in a yard built for one household, and an emergency plumber in Brixton spends winter nights on burst pipework in cold basement flats.

Why a shower room in a Brixton conversion soaks the ceiling below

---

A shower in a converted flat sits on a timber floor that is somebody else’s ceiling. What holds the water back is not the tiles. Grout is porous and tile joints move, so water gets behind the surface every time the shower runs, and it is meant to meet a waterproof layer there and be sent back into the tray. That layer is the tanking: a bonded membrane or a liquid applied coating, carried over the board joints, into the corners, and lapped down behind the upstand of the tray. In a conversion it is often simply absent. Tiles went straight onto plasterboard, and the room stayed watertight for exactly as long as the silicone held.

Then the symptom appears downstairs. A brown ring on the ceiling that darkens after somebody showers and fades in between, often a foot or two from where the shower actually is, because water follows the fall of a joist rather than the shortest route. The pipework tests fine, because the pipework is fine. Silicone is a wear item. It is a joint seal between materials that move at different rates, it hardens, it shrinks off the edge of a tray, and once it lets go the water runs under the tray flange into the floor. A tray bedded on an uneven base, so that it flexes underfoot, lets go sooner.

Finding the true source matters more than anything else here, and it takes patience rather than equipment. Wetting the tray alone with the walls kept dry, then the walls alone, then flooding the waste, will usually separate a tray joint from a wall fault from a waste connection, and that decides how much has to come out. Sometimes it genuinely is a reseal. More often the tanking was never there, and the honest answer is that the tiles come off, the boards are replaced with something rated for wet areas, the corners and tray upstand are taped and coated, and it goes back in the right order with silicone as the last cosmetic detail. Nobody should re-tile before the source is known.
