Leak to dry to treated, one company in Woolwich

Woolwich mixes Victorian terraces near the Dockyard conservation area, 1930s semis around Shooters Hill and Plumstead, and dense post-war council blocks on Woolwich Common with converted Georgian former Arsenal buildings along the riverside. This range of ages and construction methods, from soft London stock brick to system-built concrete panels, means differing pipework, roofing and waterproofing standards, each ageing and failing in its own way.

Areas of Woolwich we cover

We attend leaks right across Woolwich and its neighbourhoods, including:

Common leaks in Woolwich homes

Converted Arsenal buildings and flat roof failures

Royal Arsenal Riverside's warehouse-to-flat conversions and newer riverside blocks often carry flat roofs and parapet gutters retrofitted onto historic industrial structures. Membrane joints, roof outlets and old brick-to-modern-material junctions are common failure points, letting water track silently through structural timber and steelwork long before a stain appears on plasterboard below, particularly during Woolwich's wetter winter months.

Stacked flats and bathroom leaks through concrete floors

Woolwich Common's high-rise council blocks and newer developments stack bathrooms directly above neighbouring flats, so perished shower seals, cracked tanking or a failed waste pipe seal can send water through concrete floor slabs into the ceiling below. Because concrete disperses moisture slowly and unevenly, residents often notice damp patches or bubbling paint well after the original leak began, complicating tracing.

Ageing plumbing in Victorian and 1930s terraces

The Victorian terraces around Woolwich Dockyard and 1930s semis near Plumstead and Shooters Hill frequently retain original or early-replacement pipework hidden beneath floorboards and within solid brick walls. Perished joints, corroded soldered fittings and old lead offshoots are prone to slow escapes of water that soak into lath and plaster or timber joists unseen, often surfacing only once flooring or skirting begins to distort.

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.
