"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."

"We just completed our remodeling project with Best Builders Group and it was a great experience overall. We added a master suite (appx 350 sq. ft.) to our house. We got several estimates from several construction companies and we decided to hire Best Builders Group for that because of their big experience in design, great price and great approach. The addition project was not simple at all but Zohar handled each stage of the work very productive and he always kept us up to date about the entire progress. His design was a huge advantage and it was the main thing that we couldn’t fins in the other ones. Our bathroom addition is definitely stunning and it’s our favorite part at the house now. Zohar also recommended to have a tile wall and floor tile that made the bathroom a beautiful one! More than that, he was very hard working worked extra hours because of our long schedules. Zohar and his professional crew were very respectful of our time and space. Overall, we are excited with the addition and thankful to Zohar and Best Builders group."

Plaster Repair FAQs, answered by experts

If your home was built before the 1940s and was not remodeled in the past 50 or so years, you probably have plaster walls. Aside from assuming, there are some practical ways to tell if you have plaster walls, including the following: If you knock on the wall and it feels solid, not hollow, if you can’t insert a thumbtack easily, if there are cracks that look like spiderwebs, or if your home has curved, arched, or swirled walls, doorways, or window openings.

If you have an unfinished basement or attic, you could examine the backs of any finished walls to check, too.

It is possible to apply plaster on the interior or exterior of your home, but we don’t recommend it. Plaster is easy to apply in theory, but in reality, it can be a challenging material to work with, and it’s difficult to get the finished product to look clean, even, and smooth. Many DIYers end up calling in a professional afterward to touch up the area or even redo it entirely because of mistakes they made in the process. Hiring a plaster pro will cost more, but it’s usually the best option to achieve high-quality results.

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.

Technically speaking, you can use drywall primer over plasters. However, oil-based primers work the most effectively on wall plasters. Meanwhile, water-based primers work just as well with drywalls. Nowadays, there are also universal primers suitable for drywall and plaster. Overall, you will be fine as long as you are using a trustworthy brand.

Many services include repainting to match the existing surface. Confirm with your provider.
