"Juan, repaired a few holes we had from birds pecking at our stucco. After being told we needed to replace whole trim pieces for an excessive cost, Juan inspected and was able to patch and repair the holes much more cost effectively.. He also found a couple other smaller areas that needed minor repairs and fixed those too. Juan is prompt, friendly, trustworthy, skilled and kept his word on days and arrival times. We will definitely use Juan for future projects."

"PatchMaster repaired the drywall in a 3x4' portion of the ceiling that had a water leak repaired. the estimation process was simple. Russel and I exchanged text and photos, and he came to the house to confirm his understanding of the scope of the work. I was on their schedule a week later, and the drywaller arrived a few minutes early. He installed furniture and carpet protection from the job site all the way to the door to ensure that he kept the hours clean. His demolition was fast and he let me inspect the are in the cavity before install the patch so I could quickly check for other plumbing issues. His patch work and texturing were also quick and tidy, and the match to the surrounding/untouched ceiling looks pretty good. Over all, I am very happy with PatchMaster and will use them again for drywall needs. Their price was fair as compared to several other quotes I received. I felt that Russel demonstrated the most comprehensive understanding of the work and what needed."

Plaster Repair questions, answered by experts

You’ll want to inspect your plaster walls for signs of damage before painting. If you notice soft spots, deep cracks, bubbling, or areas where the plaster is crumbling or pulling away from the wall, it likely needs repair. While small hairline cracks are common and likely cosmetic, you should address larger issues before painting to ensure a quality, smooth finish.

Plastering lasts for around 15 to 20 years without needing repairs or maintenance in most cases, and with proper upkeep, plastering can last a lifetime—sometimes more than 100 years. Plaster repair costs between $1 and $3 per square foot, and you may need these services once every 15 to 20 years or so unless you have a harsh climate where humidity changes are a constant issue. You can also opt to skim-coat plaster for between $0.90 and $1.30 per square foot, which may serve you better in the long run.

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.

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.

While you should consult with a ceiling professional for larger cracks, especially if you’re not sure what’s causing your ceiling to crack, you can certainly try to repair small cracks on your own. If you’re up for the task, here’s how to repair ceiling cracks for $150 or less.
