"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"I hired Atlas Home Energy Solutions to remove old insulation and replace it with the foam technique. However, I ran into numerous unexpected problems due to a slow leak from old pipes. It took awhile to sort out. Atlas Home Energy Solutions gave me lots of expert advice. They were willing to come out and review the situation. They were also willing to reschedule and wait until another contractor dealt with the water issue and its ensuing problems. They helped me make some difficult decisions before they could insulate the crawl space. When it was ready for them to come and insulate the area they bumped their schedule forward to get it done. This company did sterling work. Their expertise and professionalism were outstanding. They really know what they are doing and guided me through a more protracted process than originally envisioned. I would highly recommend them to anyone."

"A Hight on Homes were amazing to work with. We've now used them 5 times over the last 5 years and each time they were quick, professional, and saved us thousands of dollars over competitors. We started with a free home energy audit they were offering. They then helped us apply for government rebates to get our entire home weatherized which cut our utility bills in half! They helped inspect our roof after a hail storm, which only needed minor repairs. They helped us when our heat pump was on the fritz and offered a substantial rebate on a replacement heat pump. And then just this month we called them again when our water heater went out so that they could help us get that replaced and again, apply for a rebate for getting an energy-star rated appliance. Bobby and his team know this business so well and are some of the kindest people we have ever met. Get your home energy audit from them so that when you have an appliance go down they will be ready to help you apply for energy rebates much more quickly."

"Highly recommend for any insulation project. Dan Hope is extremely knowledgeable concerning home insulation and was pleasant to work with. I have cantilevered second story floors and poor insulation was causing a duct vent to develop condensation with this 2024 heat wave which caused moisture to drip down inside of my first floor ceiling. Dan fixed the insulation issue and then some. He inspected the house and advised improving the insulation around a room that sits above our garage that was notoriously difficult to temperature control. I would hire him again for another project in a heartbeat."

Insulation questions, answered by experts

Glass fibers are often used in HEPA filters because of their high efficiency, durability, and thermal stability. Some HEPA filters are made with synthetic fibers, but they may not be as effective. While there is some fiberglass shedding, as long as the HEPA filter is intact and not cut open, the amount of fiberglass released by a HEPA filter is well below the breathable particulate matter.

Energy-efficient homes generally have higher appraisals and appeal to buyers.

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.

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.

Heavily exceeding building code requirements for insulation not only wastes money on materials but can also lead to ventilation and moisture problems. In most cases, the minimum amount of insulation required by code is perfectly adequate.
