Damp Proofing Sevenoaks
South East Timber and Damp treat damp problems throughout Sevenoaks and the villages that surround it, from Dunton Green and Otford to Westerham. Our team, led by company owner Dean, has built a reputation for honest advice and getting the right solution first time, whatever the problem.
You'll find plenty of period and listed properties around Sevenoaks, and it's exactly the kind of property Dean's team deals with day to day.
What Is Damp Proofing
Damp proofing is the general term for the treatments used to fix or prevent damp problems in a property, whether that's rising damp, penetrating damp or condensation. The cost of damp can run to thousands of pounds if it's left untreated, so it pays to get a professional assessment early rather than guessing at a fix.
Dean is CSSW and CSTDB qualified through the Property Care Association and a member of the British Structural Waterproofing Association. He leads a team of well-qualified surveyors covering Sevenoaks and the whole of Kent, who can identify the problem and provide a guaranteed treatment plan.
Damp Proofing Around Sevenoaks
As well as Sevenoaks itself, we regularly carry out damp surveys and treatment in the surrounding villages, including Dunton Green, Riverhead, Otford, Sevenoaks Weald, Chipstead, Seal, Chevening, Brasted and Westerham.
Sevenoaks has a large number of older and listed properties, including many close to Knole Park, and these often need particular care when identifying and treating damp without disturbing original features unnecessarily.
What are the signs of damp?
- Peeling wallpaper
- Tide marks on walls
- Bubbling paintwork
- Black mould spots
Left unchecked, damp can move from a decorating problem into a structural one, affecting timber and brickwork, and reducing a property's energy efficiency. Prolonged exposure to damp conditions has also been linked to respiratory problems such as asthma, so it's worth acting quickly.
Take a look at our damp problems page for more detail on what's causing yours, and how each type is identified.

Our Customer Reviews
Damp Treatment Options
Once we've confirmed whether you're dealing with condensation, rising damp or penetrating damp, we can recommend the right fix, whether that's a damp-proof course, a damp membrane, or for basements and cellars, tanking and improved drainage. We'll always tell you if there's a simpler, cheaper fix you can do yourself first; we don't recommend work that isn't needed.
See our damp proof course and damp membrane pages for more on how each treatment works.
