"I had an emergency and JR Insulation Drywall did an amazing job. I had just sold my house, and in the process of moving, the movers broke a pipe that had to be repaired behind a wall on the day we gave possession to the new owners. I called JR Insulation Drywall and they were there the same day I called and did a wonderful job of the repair. Responsive, quality, and for a great price. Would definitely hire again if I needed help. I so appreciated their help in a stressful time for me."

"We re-sided our 1929 house recently, and during the tear-off phase it was the perfect time to have blown-in insulation performed to insulate our exterior walls. Ryan and his crew worked quickly and we are so much more comfortable with our walls finally insulated. We had a minor repair needed as a result of the drilling, and the company worked quickly to resolve it to our satisfaction. I will happily recommend them to others, and feel like this project pays for itself quickly in terms of energy efficiency and comfort."

"Ulises and his team were very efficient in their install of additional insulation in our attic. Not only that, but the price we got beat out the other two quotes! We were very happy with our hire of Ulises Pro Insulation."

"They installed new insulation for us in an um-insulated attic space. They were well-priced, on-time, and very easy to work with. Workers all wore protective equipment and were both professional and friendly."

"Kirk and his team helped investigate the source of a leak, remove and replace caulking, and repair drywall. They were efficient and did no more than necessary. Project came in slightly under the estimate as a result. I'm very thankful and pleased with their work."

"I had an extensive rat issue in the insulation under my house. The Crawlspace Crew came over the same day to give me a quote and inspect my crawlspace. They organized the entire job, including removing the insulation, setting up a new barrier, spray underneath my house with an antimicrobial chemical and reinstalling new insulation. They also orchestrated with a pest control company to come and set traps, and close up any holes that were ports of entry for the rats. They were extremely efficient at communicating back with me and Two to the timeline. Overall, I was very impressed with the Crawlspace Crew."

Drywall Insulation questions, answered by experts

Plaster is a pretty tough surface, but it can still sustain damage from things like bumping against it, water issues, dampness, extreme humidity changes, and plain old age. Most plaster walls last hundreds of years and will only be taken down to the base layer when major repairs are required. Being cautious around the wall, not placing furniture against it, and ensuring stable humidity are all great ways to reduce possible 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.

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.

It’s always better to follow proven drywall repair tips and fix the seams that look bad. However, if you simply want to make them less noticeable until you have time to fix them, you can use paint. A darker color of paint makes bad drywall tape seams less noticeable than light-colored paint. Matte paint hides bad seams better than glossy paint does, too.

It’s not a good idea to plaster over broken plaster (unless by broken you’re referring to cracked, in which case that’s perfectly fine). However, broken plaster can be a sign of a larger underlying issue like foundation damage or severe damage to the lath holding up the plaster, so it’s worth investigating before you simply plaster on top of the damage.
