"Owners did the estimate, were on site for the insulation install...what more can be said about customer service! They were 5+. Now I must tell you about the job...it was difficult adding insulation to the underside of floor boards in our crawl space. Other insulators said it couldn't be done. Kelly took her flashlight, measuring tape and looked really hard and said "We can do this!" What a "can do attitude" and they accomplished it. I will definitely use them again and so should you!"

"I called 5 Insulation companies for estimates in Oct.2025, when we were having other work done to our home & discovered we had No insulation between the studs. USA 🇺🇸 Insulation was the most expensive but they were the most thorough during the sales process, as far as explaining how everything was to be done & showed me photos. They were the ONLY company that offered the blown in expansion Insulation. Which is what made the job a little more costly, but they used the best product because it doesn't settle over time, which to me made it worth it. They came on Dec.15th which was a VERY cold day, with a 4 man crew,each with a specialized task, (Foreman, siding removal, hole driller, foam insertion). They were very professional, answered all my questions, cleaned up my property when done & did a heat camera procedure that showed me how the walls were cold before hand & were already warming by end of job. I highly recommend this company to anyone needing to have this done."

Insulation questions, answered by experts

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.

Fiberglass is the best insulation for HVAC ducting because it's inexpensive, widely available, versatile, and long-lasting. Fiberglass also offers acoustic insulation in addition to thermal insulation, which can contribute to a more peaceful home environment. You can use other materials like mineral wool, but fiberglass is the industry standard.

Water heater blanket prices range from $20 to $40 on average, though you typically won’t need to spend more than $30 for all the tools and materials required for installation—which include the blanket itself, heavy-duty scissors, and electrical tape. Blankets with higher R-values will also be slightly higher in price.

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.

The primary purpose of insulation is to maintain comfortable temperatures in a home, whether that’s cool air when it’s hot out, or warm air in winter, but that’s not all it can do. All options will also minimize heating and cooling needs, lowering both your carbon footprint and energy bills in turn. And some options, like rigid foam boards, even offer soundproofing benefits, too.
