Professional Damp Proofing & Timber Treatment Across the South West
Damp is one of the most common — and most commonly misdiagnosed — problems in Somerset properties, particularly older stone, cob and solid-wall buildings that were never built with a modern damp-proof course. Brick Builds diagnoses and treats rising damp, penetrating damp and condensation in South Somerset and across Somerset, always starting with a proper investigation rather than a one-size-fits-all chemical injection.
Our damp treatment work in South Somerset includes damp-proof course installation and replacement, tanking of below-ground and cellar walls, re-plastering with breathable lime or specialist damp-resistant renders, and improving ventilation and drainage where poor detailing is the underlying cause. Where we find timber decay — wet rot, dry rot or woodworm — we treat and, where necessary, replace affected structural timbers as part of the same project.

Damp Proofing & Timber Treatment FAQs — Somerset
How do I know if I have rising damp or penetrating damp in South Somerset?
Rising damp typically appears as a tide mark up to around 1 metre on ground-floor walls and is caused by moisture rising through the wall from the ground. Penetrating damp can appear at any height and is usually caused by a defect such as a leaking gutter, cracked render or failed pointing. We carry out a free damp survey with moisture readings in South Somerset to correctly diagnose the cause before recommending treatment.
How much does damp proofing cost in South Somerset?
Damp-proof course installation in South Somerset typically costs £500–£2,000 for a standard terraced property. Tanking a cellar or basement costs £70–£120/m². We provide a free survey and fixed-price quote before any work begins — call 01460 353121.
Is chemical damp-proof injection right for my Somerset period property?
Not always. Many older Somerset properties — particularly stone, cob and solid-wall buildings — were designed to allow moisture to evaporate naturally and can be made worse by modern chemical damp-proofing and cement-based renders. We assess the construction type and cause of damp before recommending the correct approach, which is sometimes a breathable lime-based solution rather than chemical injection.
What is dry rot and how do you treat it?
Dry rot is a fungal decay that spreads through timber and can affect masonry, and it is more serious than wet rot because it can spread beyond the original source of moisture. Treatment involves removing and replacing affected timber, treating surrounding masonry, and — critically — identifying and fixing the source of moisture that allowed it to develop. We provide a full survey and treatment plan for South Somerset properties affected by dry or wet rot.
