Plasterers in Newhaven – Replastering Damp-Affected Walls
Damp ruins plaster. Salts track through and crystallise, paint bubbles, the surface goes soft and crumbly — and painting over it just moves the stain a few months down the line. Brighton Plasterers replasters damp-affected walls across Newhaven properly, so the repair lasts.
The golden rule: fix the cause first
Replastering a wall that’s still getting wet is throwing money away — our guide on plastering over damp explains the right order in full. Before any plaster goes on, the source has to be dealt with — a failed gutter or leaking pipe, bridged pointing, ground levels against the wall, or condensation from poor ventilation. We’ll tell you honestly what we think is causing it and whether you need another trade in first. Once the wall is dry — or drying — we do our part.

- Hacking off contaminated plaster back to sound masonry
- Salt-resistant backing plasters that stop residual salts spoiling the new finish
- Breathable systems where solid walls need to dry through the surface
- Re-skimming and making good, ready for decoration
- Matching in with surrounding walls so the repair disappears
Honest scope, free quotes
Damp jobs attract overselling — whole-house treatments quoted where one wet wall needs attention. We quote for what the plaster actually needs and nothing more. Covering Newhaven, Peacehaven, Seaford and Lewes.
How long before the wall can be replastered?
Depending on thickness and how wet it got, a soaked solid wall can take weeks to dry properly — roughly a month per inch of wall depth is the old rule of thumb. We’d rather book your job for the right week than plaster a damp wall for speed, and we’ll check it’s ready before we start.

Newhaven plastering questions
Can you plaster over damp?
No — and anyone who says yes is selling you a repeat visit. The moisture source has to be fixed first; then we replaster with salt-resistant or breathable materials so the repair lasts.
How long must a wet wall dry before replastering?
As a rule of thumb, about a month per inch of wall thickness — a soaked solid wall can need weeks. We check it’s ready rather than plastering to a calendar.
Why do salts ruin new plaster after a leak?
Moisture carries salts from the brickwork into the plaster, where they crystallise and push the finish off. Salt-resistant backing plasters stop residual salts spoiling the new surface.
