Damp Proofing in Wiltshire
In the South West, exposure to wet, wind-driven weather means penetrating damp through render and pointing is common, along with damp in older stone and cob properties that need breathable, appropriate treatment.
Damp-proofing work in Wiltshire is backed by a written workmanship guarantee, because it's done by treating the actual cause — a failed damp course, an outside water-entry point, or a ventilation problem — rather than just covering the symptom.
Across Wiltshire we handle everything from rising damp treatment and penetrating damp treatment to condensation and mould control, installing a fresh damp-proof course and salt-resistant damp-proof re-plastering afterwards. Where damp has reached skirtings or joists we add woodworm and timber treatment, and for wet cellars we offer basement waterproofing — every job starting with a proper damp survey so the cause is diagnosed before any work begins.

Damp proofing in Wiltshire — frequently asked questions
Is there a charge just for a quote?
No. A survey and fixed written quote for standard domestic damp work are free with no obligation to book. Only a formal independent survey report is a separate, paid service, which we agree with you beforehand.
What other areas near Wiltshire do you cover?
We cover Wiltshire as part of a wider service area — see the nearby towns listed on this page, or get in touch with your postcode and we’ll confirm coverage.
How long does damp proofing last?
A correctly installed damp-proof course and salt-resistant re-plaster should last for decades, which is why the work is backed by a written guarantee. The key is treating the actual cause, not just covering the symptom — which is what the survey stage is for.
Do you cover both homes and commercial properties?
Yes — we treat damp in houses, flats and commercial premises, from a single damp wall in a home to larger surveys and waterproofing for landlords, letting agents and commercial buildings.
How and when do I pay?
Larger jobs are typically arranged with a deposit to book the work and the balance on completion. Full payment terms are set out in your written quote before anything starts — nothing to pay just for a survey and quote.
Damp is treated by cause, not by symptom: rising, penetrating and condensation damp look similar but need completely different treatments, which is why every job starts with a proper survey and diagnosis before any work is quoted.
