"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 FAQs, answered by experts

Yes, professionals install and upgrade insulation for all home or business areas.

One of the biggest disadvantages of glass garage doors is that they are not the best at insulating your garage. In the summer, heat can enter through the glass, while in the winter, heat can escape through the glass, increasing your electricity and gas bills as you crank up your HVAC unit. You can help mitigate the poorer insulation by investing in insulated glass and insulating your garage.

Yes, spray foam insulation can be applied to your ductwork and effectively insulate your ducts. Blanket insulation is the easiest insulation product to DIY since it is easy to wrap around ducts. However, spray foam insulation can also benefit your HVAC system if applied to air ducts.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

It depends on your needs and preferences, though many homeowners think it is worth it. Not only is blown-in insulation easy to install, but it is highly efficient with thermal regulation. Most types are mold-resistant, flame-resistant, insect-resistant, and, most importantly, completely safe.
