“Excellent service from start to finish. The survey was thorough and professional, with honest, evidence-based advice rather than trying to sell unnecessary work. I came away with complete peace of mind.”

Local knowledge

Damp problems common in Swanage & Purbeck

A coastal location and traditional stone construction create a very particular set of damp risks. These are the ones we treat most in the area.

Penetrating damp from driving rain

South- and east-facing walls take the brunt of coastal weather. Eroded pointing, cracked render and failed sealant around openings let rain soak through solid walls.

Solid stone walls

Purbeck stone cottages have no cavity, and non-breathable cement renders or gypsum plaster trap moisture inside the wall. Breathable, correctly specified repairs are essential.

Holiday-let condensation

Second homes and lets left unheated for weeks suffer condensation and mould. Low-energy ventilation such as PIV keeps the air moving even when the property is empty.

What we do

Services we provide in Swanage

Every service is delivered by our own in-house team and backed by our 25-year guarantee.

Common questions

Everything you might be wondering

Yes. Stone cottages need breathable treatment. We assess the wall construction first and recommend repairs that let the wall dry out, such as repointing, breathable water-repellent creams or a membrane system only where it is genuinely required.

Yes. We can arrange key collection and send you a full written report with photos, so you do not need to be at the property for the survey.

No. Your initial property survey is completely complimentary and carried out with no obligation. A specialist visits your property, carries out a thorough assessment, and gives you clear, honest recommendations in plain English.

As a local, in-house team we are usually able to arrange a survey visit within a few days. Call us on 01202 287503 and we will book a time that suits you.
