Damp, Mould & Leak Detection in Morden
Our surveyors investigate persistent damp and mould in Morden’s 1930s semis and rented homes, find hidden leaks without tearing rooms apart, and write clear reports for landlords, tenants and insurers — across SM4.
Why Morden homes get damp, mould and hidden leaks
Morden grew quickly after the Northern line terminus opened in 1926, so much of SM4 is 1930s semi-detached houses alongside the large interwar St Helier cottage estate and a good deal of later council and rented stock. That housing profile drives a specific mix of problems. The 1930s semis often have solid or shallow floors, cavity walls and original render that traps moisture, and we regularly trace leaks under kitchen and bathroom floors and behind chimney breasts. In the rented and estate homes the bigger issue is usually condensation and black mould in bedrooms and behind furniture, where ventilation is limited and heating is used sparingly. Mould is a symptom, so we find the moisture source first rather than just wiping it away.
Mould surveys for Morden landlords and tenants
A lot of Morden is rented housing, and damp and mould in a let property now carries a legal duty on the landlord. Under Awaab’s Law, a reported damp and mould hazard must be investigated within a set timeframe and a written summary provided, with dangerous hazards made safe quickly. Our surveyors carry out a proper investigation, identify whether the cause is a leak, rising or penetrating damp or condensation, and produce a written report a landlord or managing agent can act on and a tenant can rely on. We treat the mould and, just as importantly, set out what needs to change so it does not simply come back.

MordenFAQ
My rented flat in Morden has black mould — what are my landlord’s duties? Under Awaab’s Law a landlord must investigate a reported damp and mould hazard within the required timeframe, provide a written summary of findings, and make dangerous hazards safe quickly. We carry out that investigation and produce the report.
Why does my mould keep coming back after I clean it? Because mould is a symptom. If the underlying moisture source (condensation, a leak or damp) is not fixed, it returns. We find and fix the cause, then treat the mould properly.
Is it condensation or a leak? We settle that on site with moisture readings and thermal imaging. Condensation and a hidden leak look similar on a wall but need completely different fixes, so we identify the real cause before recommending work.
Can you find a leak without smashing the house up? Yes. We use thermal imaging, acoustic listening and moisture mapping to pinpoint a leak under a 1930s floor or behind a wall, then open up only the spot that matters.
Do you provide reports for landlords and agents? Yes. We produce clear written damp, mould and leak reports that landlords, managing agents and insurers can act on, with photos and moisture readings.
