These are the most common warning signs that damp is already present or developing. The sooner it’s diagnosed, the less it costs to fix.
Damp patches on lower walls
Particularly at low level — often a sign of rising damp or a failed damp-proof course
Black mould on walls or ceilings
Recurring in corners, around window frames, or behind furniture — especially bedrooms and bathrooms
Peeling wallpaper or blown plaster
Bubbling paint or wallpaper lifting from the wall — moisture is present behind the surface
Persistent musty smell
A damp odour that returns after cleaning is a reliable indicator of a moisture source that hasn’t been found yet
Salt deposits on brickwork
White crystalline marks on brick or plaster (efflorescence) — a hallmark sign of rising damp
Surveyor or solicitor flagged damp
A homebuyer’s survey has flagged moisture — get an independent specialist opinion before proceeding

Why choose us

Our survey process
A Structured Methodology That Misses Nothing
Unlike a quick once-over with a single moisture meter, our four-step process treats every London property individually — because damp in a Victorian terrace is not the same problem as damp in a 1960s flat.
Exterior Inspection
We examine roof, guttering, pointing, and the DPC line before stepping inside — where most surveyors start
Outside-in approachMoisture Mapping
Calibrated meters in every room create a moisture baseline — not a single reading taken and guessed upon
Room-by-room dataRoot Cause Analysis
We cross-reference age, materials, occupancy, and local environment — so your diagnosis is accurate, not generic
No blanket diagnosesWritten Report
A clear report with photos, readings, diagnosis, recommended works, and a cost estimate — no jargon, no hard sell
Delivered in 48–72hrsWhat we diagnose
Types of Damp Our Surveyors Identify Across London
London’s mix of Victorian terraces, Edwardian semis, 1930s builds, and converted flats means damp presents very differently across the city. Correct identification is essential — the wrong treatment makes the problem worse.
Rising Damp
Moisture travelling up from the ground through porous masonry. Look for tide marks, efflorescence, and damaged skirting boards on lower walls.
Common in: Hackney, Camden, Islington Victorian terracesPenetrating Damp
Water entering horizontally through failed pointing, render, or around window frames. Patches typically appear after rainfall and are located higher on walls.
Common in: North London period properties, bay-fronted housesCondensation & Mould
The most common damp type in London flats. Warm moist air meets cold surfaces — typically external walls and window frames. Frequently misdiagnosed as a leak.
Common in: London flats, converted and HMO propertiesStructural Leaks
Localised wet patches traced to plumbing faults, flat roof failures, or blocked drainage. Requires systematic elimination of other damp types first.
Common in: Basements, flat-roofed extensions, older bathrooms⚠ Damp & Mould Are a Health Risk — Not a Cosmetic Problem
Prolonged exposure to mould spores — particularly black mould (Stachybotrys chartarum) — is associated with serious health consequences, especially for children, elderly residents, and anyone with respiratory conditions.
Don’t Wait for the Problem to Get Worse
A professional survey is the fastest way to get a diagnosis and a plan. CSRT-certified surveyors available across most London boroughs this week.
