Damp Proofing in New Haw
Damp doesn't get easier to live with the longer it's left, so if there's a tide mark, blown plaster or spreading mould at a property in New Haw, we'll survey it, tell you honestly what's causing it and fix it — one of many jobs we handle regularly across Surrey.
Quick answer
Damp proofing in New Haw starts with a free survey to diagnose whether it's rising, penetrating or condensation damp, followed by a fixed written quote. Most single-wall treatments start from around £350, with the work carried out at the source and backed by a written guarantee.
How does damp proofing work in New Haw?
The South East has a mix of period cottages, commuter-town housing and converted flats, so jobs range from a single rising-damp wall to full ventilation and condensation schemes and basement waterproofing.
Getting the diagnosis right is everything with damp in New Haw — rising, penetrating and condensation damp look similar but are treated in completely different ways, so we always survey and confirm the cause before quoting rather than guessing from a photo.

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?

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.
