Damp & Mould Problems in Hillingdon
Hillingdon’s housing stock (covering UB1 and surrounding postcodes) includes post-war housing and modern estates. These properties commonly experience rising damp, penetrating damp through failed pointing and flashings, condensation mould in poorly ventilated rooms, and hidden leaks from ageing pipework.
Our surveyors attend properties across all of Hillingdon and carry out thorough moisture investigations using thermal imaging cameras, electronic moisture meters and boroscopes. We produce clear written reports with photography, moisture readings and a remediation plan, written for insurers, solicitors, housing authorities and local councils.
Common Damp & Mould Issues in Hillingdon
Properties in Hillingdon frequently present with:
- Rising damp: ground moisture wicking up through failed damp proof courses in older properties
- Penetrating damp: rain water entering through failed pointing, render, flashings or flat roofs
- Condensation and mould: thermal bridging and inadequate ventilation causing black mould
- Hidden leaks: concealed pipe failures behind walls and under floors, often undetected for months
- Water ingress: basement flooding and groundwater penetration in lower-ground properties

What we do in Hillingdon
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
Urgent cases are prioritised when water is coming through a ceiling or a pipe has burst.
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.

What types of damp do you treat here?
We treat all types of damp: rising damp (ground moisture rising through walls), penetrating damp (moisture entering through external walls or roof), condensation damp (from poor ventilation), and leak-related damp from plumbing or drainage failures. Every survey identifies the root cause before treatment is recommended.
Are your reports written for insurers and solicitors?
Yes. All our damp surveys, mould inspections and leak detection reports are written in a clear, evidence-based format for insurers, and for solicitors handling property disputes and conveyancing. Reports include full photographic evidence.
Do you provide reports suitable as supporting evidence for housing, landlord or compliance matters?
Yes. We provide reports suitable as supporting evidence for housing, landlord or compliance matters investigation and remediation reports for landlords and housing associations across our coverage area. Under the Social Housing (Regulation) Act 2023, social landlords must investigate and act on damp and mould within strict timeframes. Our reports document every stage of the inspection and treatment process.

Every visit includes a clear written report, and we confirm the price before we attend. Call 0800 054 1524 or WhatsApp us for a quote for your Hillingdon property.
Water Infrastructure in Hillingdon Services
Hillingdon Services 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.
