Damp proofing in Gillingham — frequently asked questions

Do you tank basements and cellars?

Yes — we waterproof basements and cellars using tanking slurry or a cavity drain membrane system depending on the structure and how the space will be used. This is quoted individually after a survey as it varies a lot property to property.

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 Gillingham do you cover?

We cover Gillingham 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.
