"Angel and his crew did a great job. It was complicated because of pipe configurations in the basement. His carpenter Juan did a good job of boxing piping and providing access panels to shutoffs as requested. During the process a water pipe got punctured accidentally but he shut off the water, cleaned up and reported it right away and repaired it at no additional cost to me. The finished job looks great. Angel communicated with me throughout the process and finished the job within the time agreed on."

"Geronimo Plaster was awesome to work with. Every step of the process was excellent, from the very first contact on the phone to the completion of the work Geronimo Plaster was a true professional. Geronimo Plaster has unbeatable prices, free estimates and they do top-notch work. I had a large-sized hole in my bathroom ceiling and when Geronimo Plaster got done with the work my ceiling looked new. You couldn’t even tell that I ever had a hole in my ceiling. Most of the time when people repair drywall, afterwards you can see lines and crevices where the work was done. Not with Geronimo Plaster! My ceiling was smooth and looked like new when he was finished with the job. Also, you don’t have to worry about cleaning up anything afterwards because they did a good job of that as well. Geronimo Plaster came in and knocked the job out without playing around. Some companies milk the job so they can charge you for more hours. Not Geronimo Plaster. They were all business no games. Geronimo Plaster is trustworthy, reliable and professional. If anyone needs any home repair or remodeling work done I can say from my own personal experience with Geronimo Plaster that you can hire them with peace, knowing that the job is in good hands."

Plaster Repair FAQs, answered by experts

Plaster ceilings can sag for several reasons. In some cases, the plaster and other building materials shift and come apart over time, which is why you’ll commonly find drooping plaster ceilings in older homes. Improper installation, foot traffic, and water damage—often from a leaky roof or a broken pipe—can also cause plaster ceilings to sag.

You can plaster over regular drywall, but it's essential to prepare the surface properly. Before plastering, the drywall should be clean, free of dust, and any loose or peeling paint should be removed. Applying a primer specifically designed for plastering can improve adhesion. Some professionals recommend applying a base coat of plaster or joint compound to create a better surface for the plaster to adhere to. Proper preparation ensures a smooth and durable plaster finish over regular drywall.

It depends on the construction of your wall. Most handypeople can fix small holes in drywall. If your wall is plaster or brick, more significant damage may require a drywall contractor or a mason. Hiring a handyperson costs less than a more specialized type of contractor, but they’re not trained in all types of wall repairs.

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.

Regular inspections and cleaning to prevent moisture or pest issues.
