"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."

"I love this company! Garrett came to my home and assessed how efficient our current insulation, etc was. He was very informative and friendly — explained what we needed and how they could help. At the time, I decided to hold off and he never pushed the sale. When I was ready, he was quick to accommodate my schedule. His team: Angel, Luis, Tommy and TJ were great! They arrived early, were professional, courteous, kind, very helpful with my questions and were above and beyond to help fix things that I wasn’t even aware of. They also were more than happy to help with small problems that I had no idea how to fix. They worked quickly and cleaned up afterwards. You could tell they cared about their work which makes me feel confident that the job was done right. They were also fun to have around — my Great Dane loved them too! Garrett and Dave checked in with me during and afterwards to make sure things were going well and if I had any questions. I highly recommend Eagle Shield."

"I was impressed with Aaron, the owner. He thoroughly explained what he was going to do, and took before and after photos of the job. I have noticed a big difference in the comfort level of my home. The HVAC unit rarely kicks on, as the insulation is holding the temp much better."

"The workers did the work well. I added more attic insulation, install walkways in the attic, seal our two crawl spaces My only issue was the salesman would never get back to us with the before and after air tightness results. I wrote down the raw numbers when the workers did the air tests, but they promised 6 times that the salesman would get back to me on the final results and impact it should have on our bills. Workers great, office terrible."

"Right from the get go Brian was very helpful. He was very up-front and patiently explained all the kinds of insulation and suggested which ones to use. He even went so far as to include the inside wall insulation for soundproofing at no cost since the project was large. Very easy to work with and flexible."

"I hired these guys after getting five bids. They were cheaper for the same amount of insulation and they did not try to sell me insulation I did not need"

Local and federal rebates are available for insulation installation, which can significantly reduce your overall costs. Many utility companies offer incentives or rebates to homeowners who improve their home's energy efficiency. Contact your local energy provider or government agencies to learn about available programs in your area, and consult with a professional insulation installer to maximize your savings.
It's not necessary to remove old insulation before adding new insulation, as long as the existing insulation is in good condition—dry, free of mold, and not damaged. Adding new insulation on top of old insulation can improve your home's energy efficiency by increasing the overall R-value. However, if the old insulation is wet, moldy, or damaged, it's best to remove it before installing new insulation to prevent potential health risks and ensure optimal performance.
Insulating a house takes between five and twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the size of your home, the type of insulation, and the accessibility of the areas being insulated. Keep in mind that projects may take longer if old insulation needs removal, if there's a larger square footage, or if spaces are difficult to reach.
