Expert Advice, Informatively Formed


Chartered Surveyors

If you are experiencing damp issues within your property, you are not alone.  Damp in properties causes misery for thousands of people in Britain, with recent statistics suggesting that 6% of the entire housing stock of the UK suffers from damp.

Damp is caused the build-up of excess moisture within a building, either from internal condensation or ingress from the exterior of the property.  Damp problems can appear rapidly, following a heavy downpour, or might present slowly due to a leaky gutter, damaged roof tiles or lead flashing.  What most damp problems have in common is that you’ll only become aware of them when the obvious symptoms appear – a wet patch on the wall, bubbling plater and paintwork or swollen, rotten wood fittings.

Our specialist Damp Surveys all undertaken by Chartered Surveyors who hold the benchmark CSRT (Certified Surveyor in Remedial Treatments) and CSSW (Certified Surveyor in Structural Waterproofing) qualifications.  They will assess and correctly diagnose the extent and type of damp within your property, providing you with tailored recommendations on the most effective ways to treat the specific damp problem in your property
