"I highly recommend Insulation Inc. They provided a timely and thorough quote for insulating my garage attic. Their team arrived on time and upon completion walked me through their work and provided pictures of areas I could not see. The crew cleaned up after completing the job. The Insulation Inc. crew was professional and delivered quality work."

"Exactly as the same as the first time I air sealed my attic in my previous house. Last year when we decided to sell our house I was inspecting my house as I would have if I was purchasing it. I noticed a small (1/4") gap between the master bathroom vent fan grill and the ceiling. I could not adjust it. Upon further inspection I realize it was because the foam that was installed when my attic was air sealed had expanded creating the 1/4" gap. I had that work done two years prior by Houle Insulation. I contacted Arne and inquired if he had any suggestions. His only suggestion was that he would correct the problem. Two days later he had two workers in my attic correcting the issue. Just like the first time, they were prompt and cleaned up after the work. I offered to pay, he would not have it. He said he should have noticed when the job was originally completed two years prior. There was no discussion or haggling, he simply said he would correct it. As impressed as I was with the lower energy bill, I was more impressed with how he and his team comported themselves. Also my house was more comfortable because the temperature was more uniform within my house. This year when we moved into our new house, built in 1992, the first thing I did was call Arne to air seal the attic. My choice of whom to hire for air sealing my attic was a no brainer, Houle Insulation. They also performed a blower door test. They also sent in all the information required for me to receive an energy rebate from my utility company. The best recommendation I can make is that when I decided to air seal our new home the first person I called was Arne. He made a wise decision to correct what needed with correcting without any questions. He did what should have been done, and therefore he got my repeat business and I was happy to give my business to him!"

"I was hesitant about installing insulation in both the attic and walls, but am really glad I did. My split level was so hot upstairs in the summer and I immediately noticed an incredibly comfortable difference on the next 80+ degree day. They also made sure I knew about rebates and tax credits available. So helpful! Thank you, USA Insulation!"

"Ryan, Miguel, Luis and staff did a great job removing old insulation, inspect, clean & disinfect, spray foam, and blow in new insulation. They were efficient, kept me informed, cleaned up well, and addressed minor issues after the completion was complete. I had planned to also spray foam the basement, but we could not vacate the house (fumes) with a member in hospice. This will be done as soon as we are able. Highly recommended!"

"Ivan came out to replace our garage trim due to squirrel damage and did a fantastic job. He was timely, responsive, and easy to communicate with where I had questions. Very easy to work with Ivan. Squirrel crisis averted and garage looks very good - high quality job by Ivan. I also had Ivan look at an ice damn issue we have been having on a section of our home. Ivan assessed the insulation, showed me the issue with lack of insulation (there was only 3 inches) and the building standards, gave me a fair price on insulating, and a week later he has insulated this section of our home. I am confident this will take care of our ice damn issue. I also could not believe this was not caught when we bought our home and again had insulation checked by a company last year after paying $3000 in ice dam removal. We are very thankful for Ivan?s expertise. Ivan stands behind his work and will help if we have additional concerns. I will 110% leverage Ivan in the future at our home."

Insulation questions, answered by experts

Hanging a thick blanket over your windows will help to keep the heat inside, but only a little. Covering the glass will also prevent the sunlight from getting in, which might actually decrease the efficiency of your window overall. If you get to the point where you’re hanging blankets over your window to keep warm, call in an expert to seal around your windows to prevent warm air from escaping. They may also recommend replacing old windows that aren’t as insulative as newer window technology. Sealing a window isn’t terribly expensive and can make a big difference.

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.

Yes, eco-friendly blown-in insulation options include materials made from recycled cellulose or wool. These offer excellent thermal performance and sustainability, reducing energy consumption and environmental impact while enhancing home efficiency.

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

The heat loss through a poorly insulated attic when you’re running your furnace or heat pump during cold weather can be as high as 25%. This means you could see significantly higher energy costs to make up for this heat loss. The cost of adding insulation to the attic may eventually pay for itself through lower energy bills. If you decide to add a radiant barrier too, the radiant barrier cost may also pay for itself over time.
