"Fabia recently did a total renovation of my bathroom down to studs. The end result was a 10/10. He was punctual every day and conferred w me continually, providing advice and tips every step of the way. The finished product is a masterpiece in tiling. Of all contractors used in 30 yrs as a homeowner, I rate him at the top. He has been asked to return for a 2nd bathroom fix and will be our man for a future kitchen redo."

"Dino contacted me right away when I was looking for a handyman to help fix up my parent's home to put it on the market. There were a bunch of small projects that my sister and I just couldn't handle. Dino was super nice and we felt comfortable with him right away. He did everything we asked of him in a short amount of time. I highly recommend Dino if you want a great handyman with excellent customer service!"

"We had cracks in the dyed mortar of the bricks above our garage. Grady took the time to match the color, even with the color having aged 10 years, and you would not even be able to tell that there was new mortar. If your project is anything like ours, you will not be disappointed."

Plaster Repair FAQs, answered by experts

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.

To maintain plaster walls, inspect them regularly for cracks and seal them early. Clean the walls by dusting regularly or using a gentle, damp cloth. It's also important to avoid moisture exposure. Repainting as needed will help maintain the wall's appearance and longevity.

If you already have plaster walls and ceilings, adding new plaster costs $2 to $10 per square foot. For an average-sized room, that would come out to $1,200 to $10,000. However, the cost to replace plaster with drywall is higher—running between $720 and $1,250 for a 10-by-8-foot wall or ceiling (not including drywall finishing).

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. 

Plaster can be a difficult DIY to master, especially if you plan to plaster an entire room, rather than patch a small area. Before you begin a plaster DIY project, you need to know which tools and type of plaster to use. It's also important to know how to prepare the surface and apply the plaster for a smooth finish. If that all sounds like a lot of work, you may prefer hiring a local plaster repair contractor to do the job.
