"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 had an excellent “remodeling” experience with Zohar! Zohar came over to discuss our kitchen and bathrooms remodeling project - he listened, was courteous, gave us many options, gave us an estimate and time frame for the entire work. We found him to be slightly on the pricier side, but we would hire them again in a heartbeat! Absolutely worth each and every penny! Zohar showed up on a regular basis to make sure all was on track and was available any time we had a question/concern. He walks with you through the whole project and is in constant communication. He then gives you a 3D version photo, with the tiles you select so you can see what your kitchen and bathrooms will look like before even starting - super cool. Zohar would also approve any purchases to ensure everything would fit properly (vanity, mirror, toilet, shower fixtures). Was very comforting to have someone available to assure that all your purchases would work out. Zohar’s team was great–they know their stuff — he knows what he’s doing! All the guys were very polite, respectful of my privacy, and cleaned up every day. The work finished on time, and we were so pleased that the project cost exactly what Zohar quoted. We look forward to working with them again on our next project!"

Plaster Repair FAQs, answered by experts

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly. 

Ceiling-mounted curtains won’t damage the ceiling if they’re installed properly. Using the right anchors or securing the brackets into joists will ensure the curtain weight is properly supported and prevent damage. However, overtightening screws, using weak anchors, or repeatedly removing and reinstalling hardware in the same spot can cause cracking or sagging over time. In that case, you might have to call a pro for ceiling repair.

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.

Plastering and skimming are two different techniques for finishing walls. Plastering involves applying a thick layer of a plaster mixture—typically containing gypsum, lime, cement, sand, and water—to create a new surface. This process often requires multiple coats and is used for repairing significant damage or creating decorative textures. Skimming, on the other hand, is a technique that involves applying a thin layer of drywall compound or joint compound over an existing surface to smooth it out, covering minor imperfections, small cracks, or uneven textures for a polished look. Plastering is generally more costly and labor-intensive than skimming. Although some people use the terms interchangeably, they refer to different processes and materials.

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.
