Leak to dry to treated, one company in Lewisham

Lewisham's housing runs from Victorian and Edwardian terraces in Ladywell and Brockley to 1930s semis in Grove Park, ex-council low-rise blocks around Downham and Bellingham, and converted terraces split into flats near Catford and New Cross. This mix of aged plumbing runs, flat roof extensions and shared pipework between flats means hidden leaks are common and often go unnoticed until damage spreads.

Common leaks in Lewisham homes

Ageing plumbing in Victorian terraces

Many terraced houses around Ladywell, Brockley and Hither Green still have original or partially upgraded pipework beneath suspended timber floors. Joints corrode, soldered fittings fail and small leaks track along joists unseen for months. By the time staining appears on a ceiling below, the timber and surrounding plaster may already be saturated, so we trace the source before opening anything up.

Flat roof extensions and loft conversions

Rear kitchen extensions and loft conversions are common across Catford and Sydenham, many finished with felt or GRP flat roofing that perishes with age or movement. Water gets in gradually around upstands and flashings rather than through an obvious hole, so it can travel some distance before a stain shows, making these leaks tricky to pin down without proper investigation.

Leaks between converted flats

Large Victorian houses in Deptford and New Cross were widely split into flats, often with bathrooms stacked directly above kitchens or living rooms below. Perished shower seals, failed grout or a slow escape of water from a bath can seep through the floor into the flat beneath, causing disputes between leaseholders over which pipe or fitting is actually responsible.

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.
