"This is an awesome company to do business with. They are honest, reliable, and do an outstanding job. My insulation was very old and my upstairs had become unlivable because it was so hot. I sought out 3 bids and I decided to use this company because of the outstanding experience I had in working with them. The person who took my call was very helpful, courteous and warm. They came out right away to inspect and give an estimate. They did not try to upsell and I felt very comfortable in what they said I needed. The installers arrived on time, got the job done, were super conscientious and efficient. I cannot say enough about what a great company this is. My house feels so much better. Do not hesitate to contact them if you need insulation and you will not be sorry."

"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."

Drywall Insulation FAQs, answered by experts

Yes, professionals often repair minor wall openings made for insulation injection to restore the surface.

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. 

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.

If your premixed drywall mud is dried out or has begun to set in the bucket, you may be able to revive it by adding warm water and stirring. However, the first and most important step is to scrape off any hard, dried bits of drywall that may have accumulated toward the top of the container and throw them away because they will not easily reconstitute back into the drywall mud mix.

Technically speaking, you can use drywall primer over plasters. However, oil-based primers work the most effectively on wall plasters. Meanwhile, water-based primers work just as well with drywalls. Nowadays, there are also universal primers suitable for drywall and plaster. Overall, you will be fine as long as you are using a trustworthy brand.
