Damp Proofing in Bournemouth
A damp wall in Bournemouth isn't something to paper over — we get to the actual cause, whether that's a failed damp-proof course, water getting in from outside, or a ventilation problem, and treat it properly, as part of our regular work across Dorset.
Quick answer
Damp proofing in Bournemouth 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 Bournemouth?
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.
Getting the diagnosis right is everything with damp in Bournemouth — 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.

What causes penetrating damp?
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.
Can condensation and mould be fixed permanently?
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.
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 Bournemouth do you cover?
We cover Bournemouth 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.
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.
