"Eric responded immediately and set up a consultation. He was prompt, very polite, thorough and knowledgeable. He explained everything in detail and was very professional throughout the entire process. His pricing was also quite fair. The only reason I did not go with him was that I needed other work done outside of his area of expertise. I was able to bundle that work with another insulation contractor which better suited my budget at this time. I would absolutely recommend Eric and will definitely contact him, should I need any additional work in the future."

"Everyone I worked with at USA Insulation was courteous and professional. Cliff walked through my home and gave me a thorough estimate, going over all the work that would be done to insulate my home. Tyler and his crew arrived just over a week later. They were quick and efficient and walked me through my house to show me the work was done. I would absolutely recommend USA Insulation to anyone looking for a refresh."

"The work they did was fine, but the marketing department needs to chill out. I tried multiple times to unsubscribe from their emails and phone calls, but they just kept coming. I finally had to block them. I ordered gutters without any filter because the only option they offer is the comically huge gutter helmet. I later installed leaf filters myself."

"The salesperson who came out was very nice and professional - however, he did not tell me that I needed to have everything in the basement 3 feet from the walls. This caused us to scramble on the day of installation and i'm certain that this made it more difficult for the installers as well. Additionally, no one had warned me of how strong the smell would be initially and I had to scramble a bit to get my very young family out of the house to avoid it and/or off-gassing. The installers arrived on time and were ready to roll. They did an excellent job insulating the rim joists and did a pretty good job of cleaning up. There were some spots where I had to scrape the insulation off of the floor and wall. Overall, I would recommend them for small jobs such as this.

"Verwys has done new slider door and aluminum wrap work and all the work/results have been excellent. I would recommend them. The also repaired attic insulation work done by a previous company."
Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
