"Max was on time, professional, and very dedicated to getting the job done. He went above and beyond to paint our four rooms and our hallway - ceilings, trim, and walls. He fixed all of the drywall imperfections, moved all of the furniture, covered all of the area that was being painted and did an excellent job! He finished in two and 1/2 days. It looks to us like we have a new house. He also did an excellent job powerwashing our metal roof and gutters! We will definitely hire him again!"

"Taz was great! He responded so quickly when I reached out for a ceiling repair. He was reasonable working within my budget. He was able to get started right away, and completed the project in less than 2 days. He's very personable and easy to talk to. He explained everything he'd need to do so there were no surprises. I'd definitely recommend him to anyone I know looking for home repairs!"

Plaster Repair FAQs, answered by experts

Yes, you can speed up the time it takes for plaster to dry, but it's important to do so carefully to avoid issues like cracking or crumbling. Proper ventilation is key; open a window or use a fan to circulate air in the room. Heat can also accelerate drying, but be cautious, as too much heat can cause the plaster to dry too quickly and crack. Check the plaster's packaging for the recommended drying temperature and set the room's thermostat accordingly. While managing humidity is important, avoid using a dehumidifier, which can remove moisture too aggressively and result in crumbly plaster.

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. 

Whether you can install or repair plaster yourself depends on the project's size and your comfort level with DIY projects. It's possible to handle small repairs on your own, but for larger projects like a room restoration or a full installation, it's often best to hire a local plaster professional. The final appearance, even coverage, and durability of the plaster depend heavily on proper wall preparation and application. If you are not 100% confident in your ability to achieve a professional result, letting an expert handle the job is a worthwhile investment.

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.

Drying alone can take 1 to 4 hours to dry to the touch per plaster layer, but some types of plaster take several hours longer to dry. However, this doesn’t mean the job is done because plaster doesn’t fully harden until it cures, which can take a few days to a couple of weeks. It may take even longer if you’re building a new, pretty thick plaster wall. Allow the plaster to cure before painting it.
