Leak to dry to treated, one company in Mortlake

Mortlake's housing stock mixes Victorian and Edwardian terraces around the High Street with 1930s semis further out and newer riverside apartment blocks on the former Stag Brewery site. Many older terraces have been split into flats with shared plumbing stacks, while flat-roofed extensions and loft conversions are common, giving multiple ways for hidden water to travel unseen between floors.

Areas of Mortlake we cover

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

Common leaks in Mortlake homes

Converted terraces with bathrooms leaking to the flat below

Many Victorian and Edwardian terraces near Mortlake High Street and the station were split into upper and lower flats decades ago, often with a bathroom sitting directly above another resident's ceiling. Perished grout, cracked shower trays or a failed waste seal can send water tracking along old joists for weeks, showing up as a stain or sagging plaster in the flat below long after the leak began.

Flat roof extensions and loft conversions

Rear kitchen extensions and loft conversions are common additions to Mortlake's terraced and semi-detached houses, and many rely on flat roofing with felt, asphalt or GRP coverings. These perish, blister or lose their seals with age and weather exposure, allowing water to seep in gradually around flashing and upstands rather than causing an obvious flood, so damage to ceilings and timber below often goes unnoticed until it is extensive.

Riverside developments and older plumbing near the Thames

The newer apartment blocks built on the former Stag Brewery site and along the riverside have concealed pipework in walls and under floors, where a failed joint or seal causes escape of water that spreads through multiple units before detection. Meanwhile, older properties closer to the river retain original plumbing runs more prone to corrosion and failed connections, adding a further source of hidden leaks.

What our customers say

★★★★★

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.

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.
