Damp Proofing in Littlehampton
Treating damp properly means fixing the cause, not just painting over the symptom — in Littlehampton we survey the property, diagnose whether it's rising, penetrating or condensation damp, and treat it with guaranteed work. It's a service we run throughout Sussex.
Quick answer
Damp proofing in Littlehampton 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 Littlehampton?
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.
You don't need to strip anything back before we visit a property in Littlehampton — 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 Littlehampton — frequently asked questions
What is a damp-proof course (DPC)?
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.
Do I need to re-plaster after damp treatment?
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.
How quickly can you survey a property in Littlehampton?
We cover Littlehampton 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.
Is your damp proofing work guaranteed?
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.
Can you treat woodworm and rotten timber too?
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.
Will damp proofing be disruptive?
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.
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.
