"I contacted 6 other contractors to foam insulate a home addition that I am building. One gave me a price and then later told me he couldn't do it and gave my name to another contractor I had not interviewed and this contractor wanted to charge more. Another sent out a man who knew nothing about insulation and this rep told me only that he used to install pools had no tapes, etc.. James Ivey came out and it was clear that he knew his business. He measured up the work, gave me a fair price and completed the work and provided the data sheets for inspection. Work was done professionally, on time and no problem with inspection. After dealing with many other contractors, I can save you some time. Hire James and his company. He knows what he is doing. Passed inspection and MY inspection in a breeze."

"We hired Triangle Radiant Barrier to install spray foam insulation in a bonus room we were finishing. This is a professional operation. They responded to my inquiries promptly, provided a clear and detailed estimate, and worked with me every step of the way to coordinate the schedule. The process was smooth and easy, with online estimates, invoices, and payment processing. Needless to say, the work itself was flawless as well. This was a complex process that I hadn't been through before, but Matt Patmon went out of his way to explain everything and answer questions. And when inevitable confusions arose, Matt went out of his way to help solve problems and keep us on schedule, even when this went outside the scope of the contract. From start to finish, this was one of the best experiences I have had with any home-improvement contractor."

"Jimmie was professional, friendly and knowledgeable. Of the estimates and recommendations I received for mold remediation in my crawlspace, I thought Jimmie's approach seemed the most logical and thorough. Pricing was fair, and the service was prompt with regular communication from him and his team about progress and next steps. He even performed an extra preventative measure that wasn't included in the estimate. I highly recommend this company."

FAQs for spray foam insulation projects in Dunn, 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.
