Is there a musty smell in the hallway that never quite goes away? Paint bubbling above the skirting? A black bloom creeping across the ceiling of a loft room that cost a fortune to build? Peckham’s houses are wonderful (and old, and busy, and heavily altered) which means moisture problems here almost always have a specific, findable cause. Finding it is what our surveyors and engineers do, across SE15 from Bellenden Road and the Holly Grove conservation streets to Nunhead borders, Queens Road and the terraces around Peckham Rye.
What’s Behind the Damp in Your Peckham Home?
SE15 is essentially a Victorian district: long runs of two- and three-storey terraces, many now converted into flats, alongside post-war estates and a newer generation of infill schemes. Each brings its own moisture behaviour. The patterns we investigate most often locally:
- Condensation and mould in loft conversions: Peckham has had one of south London’s great loft-conversion booms, and a dormer bedroom that was insulated ambitiously but ventilated poorly is a mould factory in winter;
- Bathroom and kitchen leaks in terraces and conversions, where decades of re-plumbing leave joints weeping into voids between flats;
- Penetrating damp through 130-year-old solid brick, tired pointing and butterfly-parapet roof details;
- Ground-level damp where garden landscaping, bin stores or concrete paths have bridged the original slate damp-proof course;
- Persistently humid basements and sub-floor voids on the lower-lying streets towards the Surrey Canal path.
Mould Removal and Prevention in SE15
Mould is usually the symptom that finally triggers the phone call, so let’s start there. Our mould treatment service cleans and treats affected areas properly (not a wipe-down and a coat of stain block) and, critically, identifies the moisture source feeding the growth. A tenant drying washing in an unventilated flat, a cold bridge at a poorly insulated dormer cheek, and a slow waste-pipe leak can all produce near-identical black mould; the correct response to each is completely different. Landlords and letting agents in Peckham use us precisely because our reports separate building defects from ventilation and lifestyle factors with measurements, not opinion.
Condensation in Loft Conversions and Converted Flats
Peckham’s conversions deserve their own section. When a Victorian terrace becomes flats, or gains a loft room, its moisture balance changes: more people, more showers, more cooking, less connected airflow. New insulation creates warm rooms with cold corners; sealed windows remove the draughts that once carried water vapour away. We assess humidity, surface temperatures and ventilation performance room by room, so the fix (whether that’s extract ventilation, insulation detailing or simply configuration changes) is based on numbers from your property rather than a generic checklist.
Damp Investigations for Victorian Terraces
Our damp surveys take the same evidence-first approach to walls and floors: calibrated moisture readings and profiles, thermal imaging, dew-point analysis and inspection of the details that typically fail, parapets, valley gutters, sills, DPC lines, sub-floor vents. You get a written diagnosis you can rely on for a purchase, an insurance discussion, a dispute with a freeholder, or straightforward peace of mind. We have no chemical damp-proofing product to sell you, which keeps the diagnosis honest.
Water Leaks: Detection, Trace and Access
When the evidence points to escaping water, our leak detection engineers trace it non-invasively (acoustic listening sticks and ground microphones, tracer gas, thermal cameras, moisture mapping) so a hidden heating or supply-pipe leak under a ground floor can be pinpointed before anything is disturbed. For insurance claims, our trace and access service exposes the failed pipework with minimal opening-up and supplies the documentation insurers ask for. Where drains are suspected (a common story alongside Victorian footings), we run CCTV drainage surveys to check below-ground pipework and gullies.

What we do in Peckham
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.
Insurance, landlords and tenants in Peckham
Reports prepared to support insurance, landlord, agent or housing matters. Trace and access may be covered under buildings insurance, depending on the policy. We provide the photographs, readings and written evidence to support the claim. For landlords and housing providers, our reports are suitable as supporting evidence for housing, landlord or compliance matters. Written workmanship terms apply where relevant.

Frequently asked questions: Peckham
Our new loft room gets mould on the sloping ceiling every winter. Is the conversion faulty?
Possibly, but not necessarily. Sloping ceilings are the hardest part of a loft to insulate and ventilate, and even competent conversions can develop cold spots where moist air condenses. We measure surface temperatures and humidity to establish whether it’s an insulation defect, a ventilation shortfall or a roof leak, three different fixes.
The flat below ours says water is coming from us, but our bathroom looks fine. What now?
This is one of the most common calls we get from converted terraces. Leak detection can confirm or rule out your pipework without tearing out the bathroom, which usually settles the matter between neighbours, and gives freeholders and insurers something concrete to act on.
Is the damp at the bottom of my walls rising damp?
Sometimes, but bridged DPCs, splash-back from hard landscaping, condensation and leaking drains all imitate it. Because the treatments differ so much in cost and disruption, it is worth an hour of proper measurement before committing to any of them.
Do you work with landlords and letting agents?
Yes, regularly. Our written reports give agents and landlords in SE15 a clear, defensible record of cause and recommended action, which matters when responding to tenant complaints about damp and mould.
