Mould Treatment, Damp Surveys & Leak Detection in Streatham
Our surveyors investigate damp and mould in Streatham’s Victorian and Edwardian terraces and converted flats, trace hidden leaks without ripping the place apart, and write the insurance-ready report your claim needs — across SW16.
Why Streatham homes get damp, mould and hidden leaks
Streatham stretches along one of London’s longest high streets and is built mostly on Victorian and Edwardian terraces, with a large number of converted flats and mansion blocks along Streatham High Road and Streatham Hill. That mix shapes the faults we see. In the period terraces our surveyors most often trace penetrating and rising damp behind bay windows and chimney breasts, and slow concealed leaks under solid ground floors. In the many converted flats the biggest problems are escape of water from a flat above and condensation mould in cold, poorly ventilated rooms. Mould is a symptom, not the cause, so we investigate the moisture source before anything is treated.
Mould and condensation in Streatham’s converted flats
Streatham has a great deal of flat conversions, and condensation mould in bathrooms, kitchens and bedrooms is one of the most common problems we are called to. Our team carries out a thorough damp and mould survey, works out whether the moisture is coming from a leak, penetrating damp or condensation, and only then plans the mould treatment and any ventilation improvements. That is how you stop mould returning rather than painting over it — and for tenants and landlords it provides the written evidence needed to deal with damp and mould properly.
Trace, access and insurance-ready reports for SW16
Escape of water between flats is common in Streatham’s conversions and mansion blocks, and a lot of our work is trace and access with an insurance claim attached. Our engineers locate the leak non-invasively with thermal imaging, acoustic listening and moisture mapping, open up only the exact spot that needs it, and hand you a clear written report with photos and readings. We establish whether the leak sits in your flat or the communal pipework and provide the insurance-ready evidence a loss adjuster or managing agent needs.

StreathamFAQ
My mould keeps coming back after redecorating — why? Because mould is a symptom, not the cause. In converted flats it is often condensation from poor ventilation. Our surveyors find and fix the cause first, then treat the mould and improve ventilation.
I have a leak from the flat above — can you trace it? Yes. Escape of water between flats is common in Streatham’s SW16 conversions and mansion blocks. We trace the source, establish whether it is in your flat or the communal risers, and document it for the freeholder, managing agent and insurer.
Can you find a leak without damaging my home? Yes. We use thermal imaging, acoustic listening and moisture mapping to pinpoint the leak, then open up only the precise spot rather than the whole room.
Will my insurance pay for the work? Trace and access may be covered under buildings insurance, depending on the policy. We provide insurance-ready reports and evidence to support the claim.
