"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."

"I have never been so pleased!!! Alberto and his crew were hands-down the most responsive, skilled and dedicated workers I have ever had the honor of hiring. My 1877 house has all-plaster walls and this room had major cracks across the walls and ceiling (see BEFORE photos). I had three bids, and Alberto was the only one who really knew how to handle the job. One guy wanted to sheetrock over the ceiling, another was going to treat it like sheet rock with taping and joint compound and another just said he'd spackle. Alberto knew just what to do to repair it and I knew he knew because an old friend of mine had done the same approach years ago on some cracks in a different room. It took three days just to prep and repair the walls and ceiling. Once they moved on to painting, this too was complicated because I had three different colors and molding and trim work. I couldn't believe how smooth my walls and ceiling were and how gorgeous my bookcase looked (see AFTER photos). I also added a hallway because I was so pleased with what they were doing I didn't want them to leave. Besides the exceptional quality of the workmanship, I have to comment now on the fact that they cleaned up each day and showed up when they said they would. What put me over the roof was the fact that Alberto said they would come on a Saturday because he wanted to get the job done by Tuesday (and I had added more work). Saturday was a major snow storm. I live on a big hill that wasn't even plowed but sure enough Alberto and his crew showed up in a four-wheel vehicle to get the job done. I already am planning my next painting project for them. I have had a lot of workers doing many jobs on my house over the years and Alberto is the ONLY one I have ever been fully satisfied with. I confidently and highly recommend them."

Plaster Repair FAQs, answered by experts

Your walls are likely cracking due to fluctuations in the temperature outside. Drywall tends to expand and contract when temperatures and humidity levels change, and this repeated movement can lead to cracks in your walls, particularly around door frames. If you have multiple diagonal cracks, you may want to have your foundation inspected, as cracks can also be a sign of a bigger issue.

Common causes include water leaks, settling, and impact. Address underlying issues to prevent recurring damage.

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.

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.

Yes, you can apply new plaster over an existing plaster surface, such as a wall or ceiling, provided the old plaster is in good condition. Before you begin, check the stability of the existing plaster. The surface must be clean, free of loose material, and have no peeling paint. It is also recommended to roughen the surface slightly to promote adhesion. For older plaster, applying a base coat like a PVA emulsion or a specific bonding agent or primer is crucial. This step makes the existing plaster less porous and ensures the new and old layers adhere properly for a smooth, long-lasting finish.
