"Dennis and his son Nathan were great! Expert service, did what was promised, and more! The quote was lower than other company quotes, and that included a higher R rating. Definitely got more for our money...at a lower price, and appreciate the opportunity to provide business to a local small business. Due to our tight schedule and urgent need as our attic was exposed over the garage, D&N even squeezed us in after hours because the cold weather was settling in. We not only recommend this company, we will call them in the future for further insulation needs. Grateful for their service and the recommendation from Angie's List."

"I had someone come out to my home to take a look and they were very professional and answered every question I had. The install guys came a couple days later and they were both great and showed me the work they did and I was very pleased. So far I have noticed a huge change in my bill and will definitely be recommending to my friends and family!"

"The owner of USA Insulation, Mark Owens, and his associate spent over an hour inspecting every nook and cranny of my 2800 Sq. Ft. two story home. After which, Mark spent a lot more time reviewing the current situation regarding my home's insulation. Then he thoroughly explained what needed to be done to correct the situation I was so impressed with his knowledge and professionalism and explanation of options. In the end, I decided that the one or two more years I intended to be in this home was not worth the investment. I suggested a partial and less expensive fix that would have resulted in a contract for him. Instead of taking my money, he explained why this would not fix the issue in the coldest room in the house and why it would not be a wise investment for me. I have great respect for his integrity and would recommend him as a professional of the highest caliber. If I should decide not to move in a few years, I will be calling USA Insulation, Mark Owens."

Insulation questions, answered by experts

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

If you have blown-in insulation, using an insulation vacuum will quickly and easily suck up all the insulation. Many come with built-in HEPA filters for added safety. While some people suggest breaking up large batts and feeding them into the vacuum, this can expose you to more fiberglass fibers. With batts and rolls, carefully removing them and placing them into garbage bags is a better process.

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.
