"Luis was on time, professional, polite, very reasonably priced, and he did impeccable work. Each project i gave him big or small, he completed beautifully. I’ve lived in my house 27 years and have dealt with more house issues and repair/home improvement people than i can count. Luis is the only one I have ever wrote a review for because in all honesty he’s the only one I can highly recommend for any work you need done in your home. FIVE STARS.."

"When confronted with a crisis because of a copper plumbing burglary, Mr. Grady, of Grady's Painting, Plastering and Construction, willingly traveled many miles to come to my aid. Requesting only a $1.00 deposit against a $4,500.00 job, he masterfully reconstructed my nineteenth century lath and plaster hallway wall, also thoroughly compensating for a missing portion of a central stud unwittingly removed by a plumber! After his extensive search for appropriate composition and dimension of material, he replaced and replicated a section of my forty-year-old faux onyx tub surround with common white PVC sheet, tinted oil-based colors, glaze, paint brush, and a rag. His applied natural talents and superlative skills saved me thousands of dollars! On the basis of both professional conversation and knowledgeable observation, Mr. Grady possesses the intrinsic knowledge of old-world trades, the artistic capabilities, the problem=solving thought processes, and the personal work ethic to accomplish a broud scope of reconstruction and restoration."

Plaster Repair FAQs, answered by experts

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.

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.

While it’s most common to sand plaster dry, it is possible to wet-sand plaster, too. Doing so can reduce the amount of plaster dust released into the air and make it easier to work in smaller, more delicate areas (such as around wall trim). However, some people find that wet sanding leads to more imperfections, which is why larger walls are more often dry sanded to ensure an even finish.

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

You can repair plaster ceilings yourself after the cause of the ceiling damage has been addressed. However, the repair can easily take 5 hours and can be slightly challenging for those without previous experience. If you do decide to flex your DIY muscle, have a helper to help hold the ladder and pass you the tools for safety purposes.
