How We Diagnose Damp in Sevenoaks
Accurate diagnosis is the foundation of effective damp treatment. Many Sevenoaks 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 Sevenoaks property and TN13, TN14, TN15 postcodes.

Frequently asked questions: Sevenoaks
How long does damp treatment take in Sevenoaks?
The duration of damp treatment in Sevenoaks 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 Sevenoaks property.
Can you treat damp in rented properties in Sevenoaks?
Yes. We work regularly with tenants, landlords, and letting agents across Sevenoaks 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 TN13, TN14, TN15 postcodes in Sevenoaks are covered.
What’s the difference between damp and condensation in Sevenoaks 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 Sevenoaks 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 Sevenoaks?
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 Kent.
Do you offer emergency damp and leak response in Sevenoaks?
Yes. For serious water ingress, burst pipe damage and severe mould in Sevenoaks and the surrounding Kent area, urgent cases are prioritised. Call 0800 054 1524. Our team will assess your situation and confirm the earliest available appointment for your TN13, TN14, TN15 postcode. Out-of-hours enquiries can be sent via WhatsApp at any time.
Water Infrastructure in Sevenoaks Services
Sevenoaks 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.
