"Needed to replace and repair lots of rotten wood, and peeling paint on the house. looked at several options, and Continental worked hard to earn my business. They made a great sell, and provided financing that worked within my budget. It may have taken a while to get the actual work started (due in part to the COVID pandemic slowing everything down) but they called me every two weeks with an update on my position in line. The house looks fantastic, and I never need to worry about rotten siding again. Would highly recommend."

Plaster Repair FAQs, answered by experts

The short answer is yes, a sagging plaster ceiling is dangerous. Sagging plaster on a wall is something you should fix immediately, but it isn’t a major concern. If the same type of sagging occurs on a ceiling, however, you could be in danger of your ceiling falling in large chunks. When plaster sags, it loses its strength and ability to hold itself up. The bonds that hold it together are strong, though, so if a sagging area falls, it will take large pieces down with it.

Look for flaking paint or air bubbles that burst and then flake away. Paint will begin to flake after being exposed to minimal moisture or water, so it’s a good indicator of any water damage. If you notice your paint starting to flake, feel the plaster underneath to see if it is soft or damp.

Smaller is better when patching holes with spackle. Any holes wider than four to six inches in diameter tend to be too wide to repair with spackle alone. You'll likely want to patch bigger holes with a drywall panel. 

Even holes measuring up to 6 inches may be challenging to fill with spackle alone. For best results, purchase a wall repair patch made from wire mesh. Cut the patch to fit over the hole, then use the spackle to hold it in place. Apply the spackle over the patch as you would for a smaller hole.

Depending on how much adhesive was used as well as the strength of the adhesive, you may have some drywall damage when removing a mirror. You can typically repair most drywall damage if it’s small by sanding the damaged area, applying spackle to smooth the damaged section so it’s flush with the rest of the wall, and repainting the area.

You can repair plaster ceilings yourself after the cause of the ceiling damage has been addressed. However, the repair can easily take 5 hours and can be slightly challenging for those without previous experience. If you do decide to flex your DIY muscle, have a helper to help hold the ladder and pass you the tools for safety purposes.
