Cost to Repair Plaster Cracks
Repairing plaster cracks involves slightly widening and cleaning the crack, covering it with self-adhesive mesh tape, and building up joint compound or plaster filler in coats. The key to a smooth repair is feathering a wider second coat, sanding it flush with the wall, then priming and painting the patched area.
Common reasons homeowners do this job
- Visible cracks in a plaster wall or ceiling
- Surface settling
- Structural movement
- Damage that leaves the plaster surface uneven
- A crack that needs repair before priming and painting
DIY or call a pro?
This is a legitimate DIY repair if you are comfortable assessing the crack, applying mesh tape, and feathering compound smooth. Consider professional help if the crack appears related to structural movement or if you are unsure about any step. Wear a dust mask or respirator when sanding to avoid inhaling plaster dust, and wear safety glasses to protect against falling debris.
Frequently asked questions
- Can I repair plaster cracks myself, or is it better to hire someone?
- A homeowner can handle this moderate repair with a utility knife, vacuum, putty knife, taping knife, sandpaper, mesh tape, and joint compound or plaster filler. First assess the crack’s depth and width and whether it may be caused by structural movement rather than surface settling. Professional help is worth considering when that assessment or the finishing work feels uncertain.
- What makes plaster crack repair more expensive?
- The price can rise with the size of the repair area, labor time, and the materials needed. Haul-away of old material and a minimum or trip charge can also affect a small repair.
- Why use mesh tape over a plaster crack?
- Self-adhesive mesh tape reinforces the crack before compound is applied. After the first coat dries completely, apply a second, wider coat so the edges can be feathered into the surrounding plaster before sanding.
- What should I check before filling a plaster crack?
- Inspect the crack’s depth and width, then assess whether it appears to come from structural movement or surface settling. Before applying filler, remove loose debris and dust with a vacuum or brush so the compound can be applied over a clean crack and mesh tape.
