"So happy I went with USA Insulation. After learning about foam insulation, I knew it was the right option for my house. They insulated my walls and attic in a day and a half, and I could feel the difference right away."

"These guys, from GW the sales man to Bradley and Adam the installers were first class. I would recommend them to anyone, both the salesman and service techs were here at the time they said , not one min. late and their care for their work is second to none. Having been in the building business for years, I can say these guys are growing a co. on quality service bar none. Also the care they have for your house is great, from start to finish, couldn't tell anyone ever set foot in my house. Also the price was hard to beat.

"We are thrilled with their work, Mitch was easy to talk to, arrived on time, explained his procedures well and did an excellent job of insulating an older home without having to tear down walls. We definitely recommend Carolina Energy Concepts, LLC for retro insulation and all insulation. We will hire him again if needs arise."

"Our builder had never used spray foam, so once we decided to go spray foam, we got a great education from Rich Brown of Prime Energy group. He was wonderful to work with, and helped guide us on some very important issues including HVAC sizing. His company had all their paperwork ready for Orange County NC inspectors, and he was very flexible given all the delays we experienced before we were ready. When our spray day finally was approaching (4 months after the initial consultation), Rich came out again to go through the job again with us, answer any last minute questions, and make sure he did not see any concerns for going forward. Once we were ready, the company sent two crews. Rich went through the job with them and they finished it in one day! The crews even did a good job of keeping the mess to a minimum, despite the fact the trimmed foam bits are very much like styrofoam to manage. The inspection went off without a blink, and the job looks great! I really would recommend them as top notch, and priced fairly for the level of job they did for us. My only remark for those considering spray foam: make sure all outlets, vent pipes or air inlets are in their final place and fastened down before spray. You cannot easily reposition or push them into place afterword, and who wants to damage their new insulation? Thankfully, we thought of that for the outside vents because those would have been a nightmare to fix. On inside, we had two outlets that were screwed only from one side rather than nailed and the dryer vent 'hutch' that was not fastened that were pushed out by the foam which are going to be difficult to fix. My husband will also have to pull the sides of our shower pan liner and cut some foam back before that area is tiled since the flexible liner pushed in, but that should be simple. We used open cell foam and are very happy with the results, and there are no weird odors or fumes after a day's curing. Call Rich, he knowns his stuff."

"Wishing there were more stars to give to Newtonian's Renovation than the 5 offered! For their estimate for more attic insulation at our house they arrived on time and went into the attic and took photos to show my husband what we currently had and what their plan was to bring us up to the R49 level. My husband discussed with them his concerns about the baffles and the HVAC unit in the attic. This company listened and discussed w hubby what their plans were to fix any issues first so the extra insulation will do the job it is for which is to make the attic more energy efficient. When the workers came to do the job they cleaned up as they went along and let my husband know their progress and again took photos to show him what the end result looks like now. This is an upstanding company and they offer more services than just attic insulation! Happy we found them through Angi.com!!"

FAQs for insulation service projects in Nashville, 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.
