Quick answers

Can cracked plaster walls be repaired or should they be replaced with drywall?

Most cracked plaster can be repaired rather than replaced. The National Park Service's plaster repair brief says loose plaster can be reattached to the lath with flat-head wood screws and plaster washers, and hairline cracks are not a serious concern when the underlying plaster is sound.

Why is my plaster wall bulging?

A bulge usually means the plaster has lost its grip on the lath behind it. Once the keys break, the section can loosen further, so it should be reattached before it falls or is patched over.

Does old plaster contain lead paint?

Painted plaster in a pre-1978 home may well have lead paint under newer coats. EPA says about three-quarters of U.S. homes built before 1978 still contain some lead-based paint, so test before sanding or demolition.

What 24/7 Express Handyman Service does on site

How it works

  1. Press along the crack to find plaster that has lost its grip on the lath
  2. Reattach loose sections, then fill cracks and holes in thin layers
  3. Prime and finish to match the surrounding wall
  4. Referred out: cracks from settling foundations or failing framing go to a structural engineer, and work that disturbs paint in a pre-1978 home follows EPA lead-safe rules

When to stop and call

If plaster is bulging, sagging or dropping pieces, especially overhead, keep people out from under it. 24/7 Express Handyman Service can secure the loose plaster and plan the repair.
