Cost wall damage repair.

Wall damage repair in the UK typically costs £80–£500 per damaged area, depending on size and cause. Common scenarios: dent or hole from impact (£80-£200), water damage from leak (£200-£600), large damaged section (£300-£800), structural crack repair after subsidence resolved (£200-£700). The price-driver is whether the cause has been addressed first; repairing damage without fixing the cause means repeat repairs.

Wall damage falls into a few categories: impact (knocks, kicks, furniture damage), water (leaks, damp), structural (settlement, subsidence), and decay (failing plaster from age). Each has different treatment paths.

Typical UK costs

Common wall damage scenarios

• Doorway damage — handles, doors slamming through, kicks. Plasterboard hole repair with backing patch and skim.
• Furniture impact — sofa back rubs, bedhead dents, chair scrapes. Sand, fill, smooth, repaint.
• Pet damage — cat scratches, dog chewing skirting and corners. Repair includes filler, decoration.
• Stairlift removal — fixings leave holes. Patch, plaster, redecorate.
• Picture / shelf removal — hole patterns from previous fixings. Fill, sand, paint.
• Water damage from leaks — cause must be fixed first; then dry, replace damaged plaster, redecorate.
• Subsidence cracks — only after structural stabilisation. Then full crack repair using flexible filler.

The damage repair process

1. Cause investigation — what caused the damage and is it stable now?
2. Cleanup — remove loose plaster, debris, water if present.
3. Drying — for water damage, weeks of drying before any repair.
4. Backing if needed — patch plasterboard or scrim tape over cracks.
5. Bonding coat — for thicker damage; not needed for skim-only repairs.
6. Skim finish — multiple thin coats trowelled smooth.
7. Sanding when dry — light sanding to remove any imperfections.
8. Decoration — mist coat then full coats of paint, or wallpaper rehang.

Things people often miss

• Don't paint over damp damage — masking with paint traps moisture. Address cause, dry walls fully, then repair plaster, then redecorate.
• Plasterboard repair needs backing — small patches in plasterboard need a wood or metal backer behind, otherwise the new plaster has nothing to support it.
• Movement cracks need flexible fillers — for cracks that flex with seasonal house movement, flexible decorator's caulk holds better than rigid plaster filler.
• Match texture if textured — patching textured walls (artex, woodchip) needs texture matching, not just smooth filler. Specialist work.
• Insurance claims — water damage is often insured under home policy. Get the loss adjuster's instructions before commissioning repairs; some insurers want their own contractor.
• Document before repair — for insurance or rental damage claims, photograph everything before any repair starts.
• Wallpaper vs paint — repairing paint-over-plaster is straightforward; repairing paper-over-plaster needs full repair plus repapering, which is messier and pricier.
