“Excellent service from start to finish. The surveyor was professional, thorough and explained everything clearly. The damp problem in our Victorian terrace has been completely resolved. Highly recommend.”
“Used Damp Mould Leak after my tenant reported black mould. They came out quickly, produced a detailed report for my insurer and sorted the problem efficiently. First-class service.”
“Found a mystery leak that two plumbers couldn’t locate. DML tracked it down within an hour using specialist equipment. Very impressed with their expertise and professionalism.”
“Brilliant company. They handled my Awaab’s Law compliance report quickly and professionally. As a housing association, we rely on specialists like this. Will definitely use again.”
“The mould in my bathroom was back within months of DIY treatment. DML found the root cause — a slow roof leak — fixed it properly and treated the mould. No return in 8 months. Worth every penny.”
“Called on a Monday, they were at my property on Wednesday. Thorough survey, clear written report and honest advice. No upselling, no pressure. Very refreshing compared to other companies I’d tried.”
“Had a central heating leak hidden behind my kitchen wall. DML found it with thermal imaging without any major damage. Saved me a fortune compared to the hack-and-see approach other plumbers suggested.”
“Instructed by our solicitor as part of a property purchase. Produced a detailed damp report within 24 hours. Very professional, clearly explained findings and saved us from a potentially very costly mistake.”
“Absolutely first class. The team treated my property with care, kept disruption to a minimum and left everything clean and tidy. The wet rot in my bay window is fully treated and repaired. Excellent workmanship.”
“Used them for a CCTV drainage survey before buying a house. Found a root intrusion that would have cost thousands. Report was detailed, professional and accepted by our surveyor. Saved the deal and saved us a disaster.”

Frequently Asked Questions
Do you cover emergency same-day appointments?
Yes — for burst pipes, active water ingress, and severe mould situations that pose a health risk, we prioritise same-day attendance. Call 0800 054 1524 and explain the urgency. WhatsApp is also monitored for out-of-hours emergencies.
How do I know if my property has rising damp?
Rising damp typically presents as tide marks on lower walls, white salt deposits (efflorescence) near skirting level, peeling or bubbling wallpaper and plaster, and a distinctive musty smell. In older properties without modern damp proof courses, rising damp is common. A calibrated moisture meter survey confirms whether what you’re seeing is genuine rising damp or another form of moisture problem.
Can damp cause health problems?
Yes. Damp conditions encourage mould growth, which produces spores and mycotoxins that can cause or worsen respiratory conditions, allergic reactions, and in vulnerable people (children, elderly, and those with asthma or immune conditions) more serious health effects. Black mould (Stachybotrys) is particularly problematic. Professional treatment addresses both the mould and the underlying damp that feeds it.
Do you work with letting agents and property managers?
Yes. We work regularly with letting agents and property management companies across our coverage area. We offer priority attendance for managed portfolios, Awaab’s Law compliant reports, and standardised PDF reports that integrate with property management systems. We can liaise directly with tenants or landlords as required.
What happens if mould keeps coming back after treatment?
Recurring mould indicates the underlying damp cause has not been fully resolved. Mould treated without addressing the root cause — whether condensation, rising damp, a structural leak, or a plumbing issue — will return within weeks or months. Our surveys identify the root cause and our treatment includes addressing it, not just treating the surface symptom.
