"We had a bilco door that leaked water into the basement steps. We needed our basement bilco door sealed and Juan was able to stop some of the leaking. He also sealed a crack in our front steps. He worked diligently on both areas and well into the evening. We appreciated his work ethic and his pleasant demeanor. Juan did his best with our project. However, we feel the door may need replacing."

Plaster Repair FAQs, answered by experts

Plaster repair costs range from $4 to $10 per square foot for refinishing, while skim coating can be less expensive, usually between $2 and $5 per square foot. The price you pay for plaster repairs will depend on the extent of the damage, the type of plaster you have on your walls, and the accessibility of the damage. Plaster repair on the exterior of your home tends to be more expensive, as there’s a higher chance that ladders or scaffolding will be necessary to carry out the repair.

Yes, you can apply new plaster over an existing plaster surface, such as a wall or ceiling, provided the old plaster is in good condition. Before you begin, check the stability of the existing plaster. The surface must be clean, free of loose material, and have no peeling paint. It is also recommended to roughen the surface slightly to promote adhesion. For older plaster, applying a base coat like a PVA emulsion or a specific bonding agent or primer is crucial. This step makes the existing plaster less porous and ensures the new and old layers adhere properly for a smooth, long-lasting finish.

Repairing plaster walls or ceilings is almost always worthwhile. It restores the appearance of your home, and if it's an exterior wall, the repair can improve curb appeal and provide a great return on investment when selling. Plaster repairs can also reinforce the wall, preventing minor cracks from spreading, and improve your home’s energy efficiency by fixing gaps in the insulative material, potentially lowering your heating and cooling bills. Additionally, hiring a professional allows them to check if the damage is from a serious underlying issue, such as foundation instability. Catching a problem like this early could save you thousands.

To maintain plaster walls, inspect them regularly for cracks and seal them early. Clean the walls by dusting regularly or using a gentle, damp cloth. It's also important to avoid moisture exposure. Repainting as needed will help maintain the wall's appearance and longevity.

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.
