Leak to dry to treated, one company in East Dulwich

East Dulwich is dominated by long terraces of Victorian bay-fronted houses, many now split into upper and lower flats, alongside Edwardian conversions around Lordship Lane and Goose Green. Original single-brick construction, shared soil stacks and flat-roofed rear closet wings mean a leak in one flat often tracks straight into the ceiling of the flat below.

Common leaks in East Dulwich homes

Victorian terrace conversions and shared pipework

Many East Dulwich terraces off Lordship Lane and Barry Road were split into flats decades ago, leaving original lead or early copper supply pipes buried under floors shared between separate households. A failed joint or perished washer upstairs can soak through lath and plaster ceilings before the downstairs occupier notices, making the source hard to trace without opening up floor voids.

Flat-roofed rear additions and closet wings

The rear closet wing extensions typical of East Dulwich's period houses, plus later kitchen and bathroom additions, are usually finished with flat felt or asphalt roofs. These sit low and collect debris from surrounding gardens and trees, and once the membrane perishes or blisters, water tracks along joists and appears as staining well away from the actual breach, often above kitchens below.

Upper-floor bathrooms over converted flats

In houses split into flats around East Dulwich, upstairs bathrooms often sit directly above another household's living space rather than a garden. Failed shower tray seals, cracked grout or an overflowing bath can send water through the floor into the flat below within minutes, and because the two households manage plumbing separately, escapes frequently run unnoticed until the ceiling below is saturated.

What our customers say

★★★★★

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.

I have been dealing with damp and mould for years but these guys were able to come in and resolve the problem quickly and professionally. Their prices were fair and reasonable and they got the job done clean. 10/10 would use again and would recommend.

Tip: If your water meter ticks over with every tap off, or a wall or ceiling stays damp with no obvious cause, there is a hidden leak. Finding it early is far cheaper than repairing the mould and damage it leaves behind.
