"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."

"They were great at explaining the many options they offer. At first I was overwhelmed. They patiently explained why I needed this and that option. We had our attics insulated and our Crawlspace dry iced to get rid of mold. Then we went back with white foam board with lights running throughout the Crawlspace. A dehumidifier in Crawlspace is preventing mold from reforming. They were wonderful and professional. 2 thumbs up!"

"Spray Foam Insulation of North Carolina was quick to respond to my initial inquires and they were quick to provide me a quote. I have a 30' x 40' x 12' high metal building sprayed with closed cell foam 2" thick. So far, it seems pretty good. Before (in month of March cold to cool temps) the metal siding would be hot after the sun would shine on it and now it is not. The vast inside building temperatures swings have been greatly reduced. I will have to wait until this summer to see how it handles summer temps and humidity. I plan on having a dehumidifier and window A/C to help maintain temps/humidity during the summer. The only negative thing is that they drop sheet metal screw all over the place. I'm surprised that I haven't gotten a flat tire yet, but other than that all was good."

"We recently worked with Evergreen Foam & Insulation on a new construction project where they applied spray foam insulation to the walls and roof deck. Their team was professional, efficient, and maintained clear communication throughout the process. The quality of their work met our expectations, and they completed the job on schedule without any issues. The attention to detail during application was excellent, and the site was left clean and ready for the next phase of construction. We’re pleased with the results and look forward to working with Evergreen Foam & Insulation on future projects."

FAQs for spray foam insulation projects in Raleigh, 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.
