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.
What we do in Morden
Every job starts with finding the real cause — not painting over the symptom.
Mould treatment & investigation
We find the moisture source, treat the mould and tackle the cause so it is far less likely to return — with a written report.
Damp & mould surveys
A proper diagnosis — condensation, penetrating or rising damp — so you fix the right thing once.
Leak detection
Thermal imaging, acoustic and moisture tracing to pinpoint a hidden leak before any wall comes down.
Emergency & burst pipes
Genuine 24/7 call-outs when water is coming through a ceiling or a pipe has burst.
Trace & access (insurance)
We find and expose the leak and document it for your escape-of-water claim.
Insurance-ready reports
Clear, evidenced reports written for insurers, solicitors and managing agents.
Moisture mapping & thermal imaging
Calibrated readings and thermal surveys that show exactly where the moisture is — and where it isn’t.
CCTV drainage surveys
Camera surveys that find blockages, collapses and leaking joints that feed damp into a property.
Real investigations by our team
Genuine photographs from DML jobs across London & Surrey — not stock imagery.



How we investigate
Non-invasive first. We open up only when we know exactly where the problem is.
Visual inspection
A methodical room-by-room inspection of the affected areas, inside and out.
Moisture readings
Calibrated moisture meter readings across walls, floors and ceilings.
Thermal imaging
Infrared scanning, where suitable, to reveal hidden moisture and cold spots behind finishes.
Acoustic & tracer gas
Acoustic listening and tracer gas, where suitable, to pinpoint concealed pipe leaks.
Pressure testing
Pressure testing of heating and supply pipework where suitable.
Photos & written report
Photographs, readings and clear findings in a written report you can act on.
Insurance leaks & trace and access
Trace and access may be covered under buildings insurance, depending on the policy. We provide insurance-ready reports and evidence to support the claim. Our Morden engineers give you the non-invasive trace, the photographs and readings, and a written report you can hand straight to your insurer or loss adjuster.

Frequently asked questions — Morden
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.
