Batt, Rolled or Reflective Insulation Install or Upgrade
I had my crawl space encapsulated. An evaluation was completed, and an online Zoom appointment was scheduled to review the proposal and the different options that were available. This Zoom call was very beneficial and gave me a greater understanding of the different options that were available. A decision was made on the work to be done, and the work was scheduled in a reasonable amount of time. The work was scheduled to occur over two days. The employees arrived on time and finished on time with no surprises. Once the work was completed, another appointment was scheduled with the inspector from Triangle Radiant Barrier, to have an independent inspection of the work that was done. There were no surprises. The work was done right the first time! I highly recommend Triangle Radiant Barrier.

I am very pleased with the job Triangle Radiant Barrier did encapsulating my crawl space and attic. While it is too soon to quantify the benefits, both spaces have undergone a significant transformation. If you are looking to encapsulate, I would highly recommend this company. Very professional!

Batt, Rolled or Reflective Insulation Install or Upgrade
This is one of the best small investment that I made. The air in our crawlspace, smelled organic or musty. The neighborhood and home is two years new, before that, this was a tobacco field for about 100 years. The encapsulation services rendered fixed the issue. Never once did they try to oversell if anything, they are an advocate of not having the homeowner make unnecessary repairs or payments.

This company did an outstanding job testing, explaining the results, and encapsulating the crawl space. Not only do they do a wonderful job but they also enjoy working with customers. Thank you so much. I have noticed an immediate result in the air quality of our home and my headaches are no more!

Professional and honesty. That pretty much sums up our experience in 2 words. I would recommend them to others who have a potential problem with a crawl space.

This is a first-class organization!!! Just recently had a vapor barrier installed by TRB and the quality was top notch!! I was kept informed throughout the entire process. All of the Team members had smiles on their faces, arrived early and communicated frequently throughout the entire process. I also had a follow-up inspection to ensure the work was done to my satisfaction. It is a shame that more companies do not operate like Triangle Radiant Barrier. I will definitely call on them in the future for any needs!

We had our attic insulation replaced and gaps sealed. We also had a door replaced to our side attic. Charlie made the perfect door that looks great and keeps all the heat out of our house. Really wish I had all this done years ago!

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.

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!

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!

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.

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.

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!
