"Glen has been my go-to plaster repair expert for more than 15 years. His work is always top quality. I have seen him fix drywall in very tricky locations on small and extensive projects. He is reliable, punctual and reasonably priced. I recommend him without reservation."

"Did a great job plastering the exterior of my house. Covered the areas where a door had been removed and windows had been enlarged to perfection. All the work was very detail oriented and completed on time. Kept the area clean and neat as he completed each stage of the work. I would highly recommend Robert for any job large or small."

"Zohar at Best Builders Group came out to our house in order to check and see how and what to change in the existing kitchen. Zohar and his team of people did a wonderful remodeling job from A to Z. We were very impressed and surprised from the high quality of the work and from the professionalism of the workers. During the work, several issues came up during the remodeling project but the team and Zohar handled all of them with no effect to the completion date and with no additional cost. We are looking forward to hire them soon and to remodel all of our bathrooms."

Plaster Repair FAQs, answered by experts

It’s not a good idea to plaster over broken plaster (unless by broken you’re referring to cracked, in which case that’s perfectly fine). However, broken plaster can be a sign of a larger underlying issue like foundation damage or severe damage to the lath holding up the plaster, so it’s worth investigating before you simply plaster on top of the damage.

Generally, your homeowner’s insurance might only cover ceiling collapses caused by problems under the coverage, such as a busted pipe. But if the ceiling collapse resulted from owner negligence, maintenance issues, or other reasons excluded by your policy, you could be on your own. Some policies might cover damages caused by the collapse but not the repair itself. Check with your policy carrier for the most accurate information regarding ceiling collapse coverage.

You can put certain types of plaster over other types, but doing so isn't always the best idea. For example, putting a coat of gypsum over lime plaster is possible, but doing so will limit the lime plaster's breathability and potentially affect its performance.

Since cement plaster tends to leave a textured surface, no matter how much you smooth it, some people prefer to use gypsum plaster as a topcoat over cement plaster, creating a smoother surface.

Installing or repairing plaster on ceilings differs slightly from performing the same motions on a wall. You’ll apply slightly less plaster to lower the overall weight of the ceiling. Wall texturing is common, whereas most ceilings are smooth plaster. Tough coat plaster is strong, meaning you can use less while retaining a solid surface.

Like many other repair projects, the cost to fix a behind-the-wall shower leak depends on several factors. The cost of your repair may depend on the type of leak (from a clog or burst pipe), type of piping, and location of the leak. The extent of the issue and how difficult it is to access the pipes can greatly impact and increase your price. On average, you can expect to pay around $150 to $600 to repair a leaking shower.
