Frequently Asked Questions

Most single-wall damp-proof course treatments in your area 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.

They're often confused. Rising damp shows as a tide mark up to about a metre on ground-floor walls, sometimes with salt staining; condensation shows as black mould in corners, around windows and in poorly ventilated rooms. A survey confirms which it is — the treatment is completely different, so getting the diagnosis right first matters.

For most straightforward domestic jobs, yes — a survey and fixed quote are free with no obligation. A detailed independent report (for a house purchase, mortgage or dispute) is a paid, separate service, which we confirm up front.

A DPC is a barrier that stops ground moisture rising up through a wall. Older properties may have a failed or missing one; we install a new chemical DPC by injecting a water-repellent cream into the mortar course, which cures to form a continuous barrier.

Usually, yes. Rising damp carries salts into the plaster that keep drawing moisture even after the DPC is in, so the affected plaster is removed and replaced with a salt-resistant system. This is what lets the wall dry out and be redecorated without the problem coming back through.

We cover your area regularly and can usually arrange a survey within a few working days — sooner for urgent cases such as a sale falling through on a damp report.

Yes — damp-proof course treatments are carried out to industry standards and backed by a written workmanship guarantee. We confirm the exact terms and length in your quote before any work starts.

Yes. Damp and timber problems usually go together — where damp has caused wet rot, dry rot or woodworm in joists, skirtings or timbers, we treat the timber as part of the same visit once the moisture source is dealt with.

Most single-room DPC and re-plaster jobs take one to three days. There is some dust and mess while old plaster comes off, but we sheet up, work room by room, and clear up as we go so you can stay in the property in most cases.

Yes. If a mortgage valuation or buyer’s survey has flagged damp, we can carry out an independent specialist damp survey and provide a written report and quote — often what’s needed to keep a sale moving.

Penetrating damp comes from water getting in from outside — a cracked render, failed pointing, a leaking gutter, a bridged cavity or a faulty damp-proof course. Unlike rising damp it can appear at any height, and the fix is about stopping the water getting in, not just treating the wall inside.

Yes, but it’s about managing moisture and ventilation rather than a one-off treatment. We identify why moisture is building up, treat and remove the mould, and recommend the right ventilation (extraction, PIV units or improved airflow) so it doesn’t simply return.

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.

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.

We cover your area 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.

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.

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.

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.

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.

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.
