"I contracted USA insulation to do a R35 fill for my attic and get about another 9 inches of spray in installed. They came in and quickly did the quote and provided me all the information regarding tax incentives and power company vouchers as well. They also provided a good discount if I could meet their scheduled availability. Paul the inspector was great, and the installation went well with Cassie and her co-worker today. It did not take long, and they made sure to not create a mess and clean up any particles that were on the floor. It was a painless process and no my attic is up to code and the upstairs hopefully will be a few degrees cooler."

"Standard Insulating Company was a pleasure to work with from start to finish. I had received 2 quotes prior to their quote. All of the quotes were comparable in price. However, Standard went above and beyond just blowing in insulation. They sealed around all the light fixtures and added foam to a chase I had in my attic. Who even knew what a chase was?!? They were very detailed and explained exactly what they were going to do. I did not get this level of knowledge from the other 2 companies. This is a wonderful company and I highly recommend doing business with them."

"Behr was fantastic! Nick and Dakota were extremely professional and provided a fair quote. They removed the old insulation, installed new insulation in my attic, and sealed all the gaps to help improve my heating efficiency. I have nothing but positive things to say about their work."

FAQs for spray foam insulation projects in Charlotte, NC

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.
