"We hired ThermaCore Insulation to remove our old attic insulation, air seal the attic, and install new insulation. Kamal and his crew were professional, honest, and easy to work with from start to finish. During the inspection, they found several air leaks and duct issues that other companies completely missed. They explained everything clearly, completed the work on time, and left the area clean. We noticed a big improvement in comfort right away. Great service, fair pricing, and quality workmanship. Highly recommend ThermaCore Insulation!"

"American Attic was everything they promised. Met with the owner , Sam, within a day to get a quote for removal of old insulation, rodent control and install of new insulation. He was professional and explained everything in detail of what was work was going to be done and how long it would take. We scheduled within a week at a reasonable price. His crew were neat, organized and finished on time! We were notified of some extra things that were found while they were on the job but were not pressured to have those things done. We recommend American Attic to friends or family and would definitely use them again."

"When Insulation Alliance came, they were very professional. They laid down plastic everywhere in the hallway and the bedroom. They cleaned out the whole attic. They took out the old insulation and put in the new Insulation which was R 44. They cleaned up everything and everything was clean when they left. They also sanitized the attic. You will not be disappointed that you hired."

Drywall Insulation FAQs, answered by experts

A common cause of separation between a wall and the ceiling is truss lift—this can happen to the ceiling of rooms directly under the attic when the seasons change and wood building materials dry out, shrink, and shift. Roof trusses often dry out at different speeds, and if the bottom pieces dry out faster than the top pieces, they can shrink and pull the attached drywall away from ceilings and walls, causing cracks. Fortunately, truss lift is only a cosmetic problem, not a structural problem, and you can fix it by separating the ceiling drywall from the roof trusses, and patching the cracks.

Yes, cabinets are installed over drywall. The drywall must be in good condition, and you must ensure that the wall can handle the weight of the cabinets. Secure the cabinets to studs and use proper anchoring devices, like toggle bolts.

There are several things you should not do when installing drywall. Common mistakes include: adding too many screws, over-sanding, not adding backing support, and installing drywall unevenly. You also should avoid screwing into the same place twice, installing Sheetrock with tapered edges on the outside, and making too many joints.

Yes, you can use drywall repair techniques for some types of plaster damage. Tiny holes and small cracks in plaster can be patched in similar ways to drywall. You apply the necessary compound to fill the hole, wait for it to dry, then sand it down. For larger damage, like water damage or mold, you need to use plaster-specific techniques and materials.

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.
