Leak to dry to treated, one company in Blackheath

Blackheath's housing runs from grand Georgian and Victorian terraces around the Village and Blackheath Park to the Cator Estate's detached villas and later low-rise flat conversions towards Lee and Kidbrooke. Many properties retain original cast-iron soil stacks, lead supply pipes and flat-roofed rear additions, all of which age poorly and hide leaks behind period floorboards, panelling and lath-and-plaster ceilings until damage is well advanced.

Areas of Blackheath we cover

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

Common leaks in Blackheath homes

Old pipework under Victorian and Georgian floors

Many terraces around Blackheath Village and the Standard still run original cast-iron or lead pipework beneath suspended timber floors. Joints perish and corrode with age, and escape of water often travels along joists before surfacing as a stain or damp patch metres from the actual leak, meaning the source is rarely where the visible damage first appears.

Flat roofs on rear extensions and loft conversions

Blackheath Park and Blackheath Vale have many Victorian houses extended with flat-roofed kitchens or loft conversions added for extra bedrooms. Felt and older GRP coverings degrade with UV exposure and thermal movement, and once perished they let water track along rafters and into ceiling voids, often showing up as staining well away from the original roof defect.

Converted flats with shared floors between bathrooms

Large Victorian houses split into flats are common near Blackheath Rise and Point Hill, and en suite or bathroom leaks in an upper flat frequently pass through shared floor and ceiling voids into the property below. Waste pipe seals and shower tray joints perish unnoticed, so the downstairs occupier often reports the damage before the leak itself is found.

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.
