5.0 Scott N. Willow Spring, NC

Top-notch professionals from beginning to end. Communication about project progress was great. Discovered leak in 1/2 bath toilet and let us know so we could get that fixed.

5.0 Jennifer Blakeslee Google Review

Shannon, Brock, Brian, Charlie and Robert were all quick, efficient and very communicative throughout the whole process of getting our attic up to snuff with an insulated barrier. I will recommend the company to friends in future!

5.0 Joseph Seftner Google Review

After speaking to several other companies about having my crawlspace encapsulated, I selected Triangle Radiant for the job. From the start to finish everyone was responsive, courteous and professional. They explained the process and the work to be done. The Pricing was very reasonable. The Job was scheduled, and the workers arrived on time and the job was finished in several days. After completion Quality control came and we examined the job to make sure everything was done. All in all a job well done. Thanks Joe S. Fuquay Varina

Jason, Robert and the whole team did an excellent job on my attic. They were all professional and they did exactly what I wanted them to do. I greatly appreciated their hard work.

5.0 Brian Braswell Google Review

Honest, thorough, on-time, and understanding. This was one of the best experiences plus the price was in line with the work. Very competitive.

5.0 Joe Wilkins Google Review

I am very happy with the crawl space encapsulation work done by the pros at Triangle Radient Barrier. The work was done in only two days, but the improvement was immediately noticeable. I was also pleased with the quality of their work and its affordability. I whole heartedly recommend Triangle Radient Barrier!

5.0 Frances M. Cary, NC

Top-notch professionals from beginning to end, at a surprisingly reasonable cost. I have an older home built in 1977 that had minimal attic insulation, and some of it was degraded and useless. Brian did an initial inspection and I received a summary of what needed to be done, with five different cost options. A zoom meeting with Brock clarified work elements and any questions I had. A very efficient Triangle Radiant Barrier crew installed fiberglass batts against interior walls, radiant barrier on flooring and walls, an insulation cover for the pull-down stairs, air-sealed utility penetrations, and sealed HVAC connections. Even though this work was recently done, I can already tell a positive difference. The air flow inside the house is more even (no warm/cool pockets) and I don't have to wear layers of clothing on cold nights. It's early days yet, but the insulation work should also save 10%-15% on energy costs over time. Triangle Radiant Barrier will adjust their work elements to your budget and needs, and they are 100% reliable in standing behind their work. Payment is not due until work is completed and inspected. I highly recommend them!

5.0 Thomas K. Raleigh, NC

Transparent pricing, and excellent work. After completing the work, they walk you through it and make sure you're satisfied before asking for payment. Great customer Experience.

5.0 James B. Durham, NC

Very professional

5.0 Ken B. Pittsboro, NC

Work was done carefully. They checked with me part way through the job to verify that all was going according to my expectations.
