Wall Damage Repair Costs

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.

Frequently asked questions

How much does it cost to repair a hole in plaster?

Small hole (under 30 cm): £80-£200 fitted, including matching paint touch-up. Door-shaped or larger holes: £200-£500. Whole-wall damage: £500-£1,500.

Will repair be invisible after painting?

Quality repair, properly skimmed and sanded, then painted with full-coverage paint: yes, typically invisible. Common giveaways include differential paint sheen (use full-coverage coat) or visible texture mismatch (in textured walls).

How long does damage repair take?

Small patches: 2-4 hours work + 24-48 hours drying. Medium repairs: half-day work + 3-7 days drying. Larger sections: 1-2 days work + 1-2 weeks drying. Decoration adds 1-3 more days.

Can I repair small wall damage myself?

Yes for nail holes, dents, and small (under 10 cm) chips — ready-mixed filler from B&Q, sandpaper, paint. For larger holes or anything needing skim plaster, professional work usually looks much better.

Will my insurance cover wall damage repair?

Accidental damage cover (often optional in policies) covers impact and water damage. Wear and tear is excluded. Check your policy schedule before paying out of pocket. For tenant-caused damage in rentals, document for deposit deductions.

What if the damage is from a leak that's still leaking?

Fix the leak first, then dry the wall properly (weeks, not days), then repair plaster. Repair before fixing means you'll be repairing again within months.
