How does damp proofing work in Westbury?

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.

You don't need to strip anything back before we visit a property in Westbury — the survey works out what's behind the damp, and any plaster removal or preparation is part of the quoted work, not something you have to sort yourself first.

Damp proofing in Westbury — frequently asked questions

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.

Do I have to move out during the work?

Rarely. Most damp proofing is done room by room while you stay in the property. For larger basement waterproofing projects we’ll talk through access and timing at survey stage.

How do I book a survey?

Send your postcode and a short description (photos of the affected area help) by phone, email or the contact form, and we’ll arrange a survey and come back with a fixed written quote.

How much does damp proofing cost in Westbury?

Most single-wall damp-proof course treatments in Westbury start from around £350, with a full room including salt-resistant re-plastering nearer £600–£1,200 depending on size and access. We always confirm a fixed price in writing after a survey — no hidden extras.

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.
