What we do in Colliers Wood

Every job starts with finding the real cause, not painting over the symptom.

Damp surveys

A proper diagnosis (rising, penetrating or condensation damp) with moisture readings and a written report.

Mould inspections & treatment

We identify the moisture source first, then treat the mould and tackle the cause.

Leak detection

Thermal imaging, acoustic listening and moisture tracing to pinpoint hidden leaks without ripping out walls or floors.

Trace & access

We locate the leak, expose the exact spot and document everything for your escape-of-water claim.

Insurance-ready reports

Clear, evidenced reports prepared to support insurance, landlord, agent or housing matters.

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.

Emergency leaks

How We Diagnose Damp in Colliers Wood

Accurate diagnosis is the foundation of effective damp treatment. Many Colliers Wood homeowners have spent money on treatments that didn’t work because the root cause was misidentified. For example, treating rising damp when the real problem was a leaking downpipe. Our approach uses multiple diagnostic tools: calibrated moisture meters, hygrometers for relative humidity, and thermal imaging cameras to identify cold bridges and hidden moisture.

Every survey produces a written report with photographic evidence, moisture readings, and a clear diagnosis. The report identifies whether the issue is rising damp, penetrating damp, condensation, or a plumbing leak, and recommends the appropriate treatment for your Colliers Wood property and the surrounding postcodes.

Frequently asked questions: Colliers Wood

How long does damp treatment take in Colliers Wood?

The duration of damp treatment in Colliers Wood depends on the type and extent of the problem. A chemical DPC injection for rising damp typically takes 1 to 2 days per wall. Mould treatment for a standard room takes 2 to 4 hours. Plaster replacement (recommended after damp treatment) adds additional time. We provide a clear timeline and schedule before any work begins, minimising disruption to your Colliers Wood property.

Can you treat damp in rented properties in Colliers Wood?

Yes. We work regularly with tenants, landlords, and letting agents across Colliers Wood to investigate and treat damp and mould in rental properties. We can liaise directly with landlords on your behalf, provide an independent written report for tenant use, or work with housing solicitors on complex disputes. All postcodes in Colliers Wood are covered.

What’s the difference between damp and condensation in Colliers Wood homes?

Damp refers to moisture entering a building through structural issues (rising damp, penetrating damp, leaks), while condensation occurs when warm, moist air meets cold surfaces. Many Colliers Wood properties suffer from both. Condensation is common in properties with inadequate ventilation (particularly flats and Victorian terraced homes) and can cause mould without there being any structural damp issue. Our survey identifies which type you have so treatment targets the right cause.

Are you insured to work in Colliers Wood?

Yes. Damp Mould Leak is fully insured. Our written reports carry professional weight and are written for insurers, solicitors, mortgage companies, and local authorities across London.

Do you offer emergency damp and leak response in Colliers Wood?

Yes. For serious water ingress, burst pipe damage and severe mould in Colliers Wood and the surrounding London area, urgent cases are prioritised. Call 0800 054 1524. Our team will assess your situation and confirm the earliest available appointment for your postcode. Out-of-hours enquiries can be sent via WhatsApp at any time.

Water Infrastructure in Colliers Wood

Colliers Wood is served by Thames Water for both water supply and sewerage. When Thames Water mains pipes fail (particularly the Victorian-era cast iron infrastructure common across South and East London), the resulting ground saturation can cause significant water ingress into nearby properties. If you have experienced unexplained damp following a Thames Water mains burst or repair in your area, our independent investigation reports establish the connection between the infrastructure event and damage to your property, supporting both Thames Water claims and buildings insurance claims.
