Damp, mould & leak services in Streatham
Streatham's housing stock is dominated by late Victorian and Edwardian terraced houses, Thirties semi-detached properties, and a significant number of converted flats within period buildings. This mixture of solid but ageing construction, combined with dense urban occupation and frequent subdivision into flats, creates persistent conditions that encourage damp, mould growth, and concealed water ingress.

Common damp problems in Streatham homes
Condensation and Mould in Converted Victorian Terraces
Many of Streatham's Victorian terraces along roads such as Leigham Court Road and Estreham Road have been subdivided into flats, often with minimal insulation upgrades. Poor ventilation in kitchens and bathrooms, combined with solid brick walls that cannot breathe effectively, causes persistent condensation. This regularly leads to black mould forming on internal walls, window reveals, and ceiling corners throughout autumn and winter.
Penetrating Damp in Thirties Bay-Fronted Semis
The inter-war semi-detached properties common across Streatham Vale and Furzedown frequently suffer penetrating damp at the front elevation. Rendered bay window sections crack over time, allowing rainwater to track behind the surface and saturate the inner leaf of brickwork. Homeowners often discover damp patches on internal plaster well after the original defect has developed, making the source difficult to trace without a thorough survey.
Hidden Leaks in Purpose-Built Mansion Blocks
Streatham Hill and the streets bordering Streatham High Road include a number of Edwardian and early twentieth century mansion blocks with ageing communal pipework and lead or early copper supply runs. Slow leaks within shared voids and between floors frequently go undetected for extended periods, causing structural dampness, stained ceilings, and damage to decorative finishes before residents or managing agents identify the source.

Service was excellent! Explained the whole process thoroughly, arrived on time when carrying out the survey. The survey was detailed and exactly what I needed for my insurance. They returned to carry out the treatment the following week. 10/10 would highly recommend.

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.
