What changes the price
- Walls now? sound painted plaster · new plasterboard · patchy or cracked · wallpapered big effect
- Room empty? empty · furnished
- Ceiling height? standard (to 2.5m) · high (2.5–3.2m) · stairwell or void
Good practice
- New board: scrim the joints; no PVA on paper-faced board
- Cracks raked out, filled and scrimmed; thicker skim over patchy walls
- Paper must come off: skimming over it fails
Prep to look for
| Condition | Check | Effect |
|---|---|---|
| Blown or hollow plaster | Tap the walls: any plaster sound hollow or move? | Cut out and re-bond blown areas £100–£300 |
| Damp or salts | Moisture meter: damp readings or white salts? | Don't plaster over live damp: find and fix the cause first |
| Wallpaper on the walls | wallpaper, woodchip or lining paper, seams, patterned paper | Strip wallpaper and scrape back |
| Lath and plaster | Lath and plaster (timber laths, hairy lime behind)? | Lath and plaster: bond the old lime first; gypsum over lime can fail if the lime is loose |
