5.0 Greg G. Fuquay Varina, NC

I used Triangle Radiant Barrier (TRB) to remediate a moisture issue in our crawlspace and advise on steps to prevent future problems. I had estimates from five different contractors and TRB was clearly head and shoulders above the other in terms of professionalism and competence. There was never any high-pressure salesmanship, nor was I encouraged to purchase options that wouldnâ t provide something I didnâ t need. They coordinated with the HVAC contractor to ensure each was able to complete their portion of the job while minimizing inconvenience to us during the process. Everything was scheduled to make our lives easier and everything was started and completed on time. Zoom conference with the owner ensured we were all on the same page and allowed for a lot of questions to be answered. The initial contacts were extremely educational without being pushy to sign and get started. The crews were on time and efficient. The end result surpassed all expectations and we are already seeing the change in our homes environment. On the rare occasion there was a miscommunication, it was handled promptly and to our satisfaction. No final payment was requested until one of the owners came to do a quality assurance inspection with us present. Everything was documented with photos both before and after completion. Highly recommend Triangle Radiant Barrier for any crawlspace or attic issue your house my encounter. Absolutely wonderful people at every level I dealt with.

5.0 Ken R. Wake Forest, NC

Always methodical, up front and organized, for the third time Triangle Radiant Barrier hit a home run for us. I feel the encapsulation is the single most important essential fix anyone could make to home with a crawlspace. Indoor air quality and humidity levels as well as home mechanicals and structural health and longevity have been immeasurably improved. Under very challenging conditions the installers make the work look easy, show pride in workmanship, and were professional in every way. Great office staff and communication, we couldn't be happier with the service and results.

5.0 Dan W. Raleigh, NC

Very professional and did great work. Our crawl space is clean and cool now

5.0 Tommy M. Durham, NC

They arrived as scheduled and made sure to place protective gear on the floors, before start of work. They completed the work in a timely manner and ask if I would like to inspect before they pulled the install equipment out. Job well done!

5.0 Kevin H. Raleigh, NC

They were professional in all aspects, including customer service, completing all contracted work thoroughly, and following up to see if we were satisfied with what we contracted for.

5.0 Chris W. Chapel Hill, NC

Triangle Radiant Barrier was awesome to work with -- super knowledgeable, professional, and timely. I would 100% hire them again in the future!

5.0 Tom W. Garner, NC

Great company! I was concerned based on other horror stories Iâ  ve heard about insulation companies, but not here. They worked with me to plan and schedule the work for a property distant from me. The crew showed up on time and completed the work professionally. The insulation was the proper depth, no over fluffing, and I love the zippered attic door the installed over the attic stairs. I highly recommend Triangle Radiant Barrier.

5.0 Stephen T. Garner, NC

Triangle Radiant Barrier did a great job installing radiant barrier in our unfinished storage and attic. I was pleased with the whole process from the beginning where all the options for treatment were clearly explained, to the professionalism of crew who did the install, and to the final inspection. The insulated zipper door for the attic stairs is great so I don't have insulation falling down every time I touch the pull-down ladder.

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.

    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
