Spray Foam Insulation in Durham, NC

Very professional and courteous. This company just did my ducting system for 1/10 of the price for new duct work charge by other company in Fayetteville. If you planning to do any type of insulation work I recommend this company. The owner give me a courtesy visit to ensure my work was done to my satisfaction. This is the way company should do business.

These guys did a great job on one of my buildings.

Very polite and quick to unload. Definitely a challenge to get backed in to there dock.

Courteous fast unloading but u will need to use your backing skills

They dismantle it quickly. But be prepared that docking will take time. A gentleman helped me; following his directions, I quickly docked. Thanks for your help.

Positive Energy has been a great company to work with. Our home (1950s house) had ZERO insulation in our attic space. Dewitt came out to our house, evaluated the attic, and explained everything he recommended very well. He made things easy to understand and was very straightforward regarding his recommendations and pricing. What we paid was more than fair and the work they did was excellent. They cleaned up well afterwards and were respectful of our whole home. We noticed an immediate difference in the comfort level upstairs, and are now reaping the energy benefits as winter has set in. Overall, very pleased and would highly recommend PENC for all insulating needs!

Could not recommend PENC enough!! Dewitt and Karen were awesome. They took the time to explain multiple different options of spray foam, coatings, and colors. They worked through my building size changes - several times. And they explained how each would work, what goes into it, (even did a cool fire demo). I feel like I actually KNOW about the product I had installed. The crew was quick, efficient, and clean!! Beyond happy with the finished product. Highly highly recommend PENC for any insulation needs!

I recently hired Positive Energy of North Carolina to encapsulate my home's attic and crawl space with spray foam insulation. DeWitt promptly responded to my query to inspect my house and provide a competitive estimate. Once the deposit was paid, Dewitt promptly did the job and dramatically improved my home's comfort. Dewitt has a deep knowledge of home performance and building science. If the need arises, I will again hire Positive Energy of North Carolina.

Oscar and his team are outstanding to work with. He was able to provide a more than fair quote from my measurements. His communication is outstanding. He provided knowledge and recommendations that made the job even better than I was expecting. The foam has reduced the temperature in the building by at least 15 degrees. The building has an exhaust fan and the amount of time the fan is running has decreased significantly after adding the foam. I highly recommend working with Oscar and his crew. They are top notch and highly competent with the foam product.

Amazing, Professional, and Affordable! I have used five different spray foam contractors. These guys are the best and they take pride in the work. They treat your house like it's their house!! Highly Recommend.

I had Oscar and his crew do a open cell spray foam on my attic space project and it turned out wonderful. They did a awesome job with pricing, quality, cleanup and great communication. I will definitely be using your service again for future projects. Thanks Oscar to you and your team job well done! 💯

The owner, Jeremy, did a great job. He was enthusiastic, knowledgeable, and great to work with. He is a good communicator and he and his crew cleaned the place up great. I would use EcoCrawls again.

We can’t say enough good things about Jeremy and his team. The air quality in our 25 y.o. home had been getting worse, and while trying to figure out the cause, we discovered that our crawl space needed serious attention. Jeremy’s team responded quickly, they checked our crawl space, found issues we were worried about, provided a clear quote, and completed the entire crawl encapsulation job within a week of the quote. Everything was handled professionally. We also had to replace our furnace at the same time, and the inspector confirmed that all of the work in the crawl space was done perfectly. The air quality in our home has improved dramatically. Highly recommend!

We had an exceptional experience with Jeremy, owner of EcoCrawls! From start to finish, the service provided by him and his team was nothing short of excellent.
The crawl space of our 30-year-old home was plagued by moisture, mold, and sagging insulation, and I’m incredibly grateful we entrusted EcoCrawls to encapsulate the entire space. The end result is a remarkable change from what it was originally. EcoCrawls expertly removed all the old materials, treated the mold, installed French drains and a sump pump to manage and redirect incoming water, and then encapsulated the entire space. The quality of work done by Jeremy and his team was outstanding, with great attention to detail and a clear commitment to high standards. I would highly recommend EcoCrawls LLC to anyone looking for top-notch service.

Triangle Radiant Barrier did a great job on my crawlspace some months ago. It looks good. The humidity sensors indicate the humidity dropped quite a bit. The tech was polite and professional. He left everything in a clean state each day. Wish I would have done this sooner. I got 5 different quotes for this job. Triangle Radiant Barrier was the right choice.

After getting multiple quotes from different companies around the triangle I decided to go with Triangle Radiant Barrier based off the reviews and the price. They did my crawlspace encapsulation and I am extremely impressed and pleased with the results. From the start I knew the company was an honest company. I started with someone coming out to take photos and measurements, then had a zoom meeting with one of the owners to go over the price and upgrade options, and then had someone reach out to schedule. Once my install date came they had the old insulation and vapor barrier out, the fungus fogging and scrubbing, and new vapor barrier down in 2 days. Then a few days later they came out and did the spray foam in less than 1 day. Afterwards one of the owners came out and inspected the work and answered all my questions. As someone who is very picky on hiring companies, I can’t say enough about how good this company treated me and my home. I HIGHLY recommend going with them for your crawlspace needs!

Triangle Radiant Barrier did an amazing job on my crawl space encapsulation. I shopped around with more than six contractors, and these guys were hands-down the most professional and knowledgeable. They took the time to explain everything and gave me several options to fit my situation. Jason and Marty knocked out the installation in just one day and did fantastic work. And huge shoutout to Ignacio — the spray foam looks great and he clearly takes pride in his craft. Couldn’t be happier. Highly recommend this team!

Insulation Commandos was a great company to work with from the beginning until they finished. The scheduling was easy and they were up front with the pricing. They were willing to help us with our situation and removed the items from the attic before they began. Even though the weather was below freezing, they removed the old insulation and replaced it with the new all in a few hours. We had a medical incident with me and the workers helped my wife control the situation. My wife said they were wonderful in helping her, which could have turned into a much worse situation. We are very satisfied and highly recommend Insulation Commandos!

Tony and his crew from Insulation Commandos transformed my crawl space from a scary mess into something far cleaner, more organized, and much more effective for moisture control. They worked around my schedule, arrived exactly when they said they would, and used high-quality materials to get the job done right—in just one day. The improvement is so impressive, I might even be brave enough to step inside someday! I highly recommend Tony and the team at Insulation Commandos for their professionalism, efficiency, and quality work.

Had the plastic sheets on our crawl space dirt floor replaced and upgraded with new, thicker, better vapor barrier that is sealed to walls and pillars. Also added a commercial dehumidifier to address summertime dampness. Tony’s team of Chris, Patrick and Parker were here for about 8 hours. I inspected at completion and they immediately took care of a few issues. Looking forward to reorganizing and using my dry, clean new looking crawl space for storage. Thanks guys!

Martin Martinez, Estiven Melgar, Grease Melgar and their entire team did a superior job on the spray form in my attic roof and attic walls. First and only estimate that I received. No need to waste my time getting more estimates after their quote. They came out the same week and did the entire job in a long 12 hour day. Nice cleanup in the attic and even vacuumed the grass area outside once they finished. A superior work quality and work ethic. A +++ to their entire team. I highly recommend General NC Insulation LLC for all your spray foam needs. A ++++++ I would hire again for other houses with no hesitation. A+++++

Estiven and Martin were great to work with, had my attic and second floor walls done with spray foam and they encapsulated my crawlspace too. Left everything clean. would recommend.

General nc insulation has now spray foamed our current home as well as our previous home. The AC in our upstairs could not keep up during 90+ degree days. Insulation solved the problem. Hhey are very professional to work with and they did a great job. Definitely recommend.

Masco/Eastern Insulation did a great job with the installation of my addtional attic insulation. They were very courteous and professional, great prices and friendly staff. Extra thanks to our rep, Cydney Graham. I would recommend them to my friends and neighbors for all their insulation needs.

Nice people. Unloaded pretty quickly. Only unload at night but you can park here if you need to

Fast unload

Dave and the team were easy to work with, responsive with questions and timely with their completion of the project. They installed the glass shower enclosure quickly and at an excellent price as well. Would use them again in the future and would recommend them for friends and family!

Tri City did a great job on our attic. They showed up on time, put down plastic and protective measures, and were finished quickly. The installation team asked me to check their work and made some final touch ups and were done quickly! Great experience all around.

Had spray foam and crawlspace plastic installed. Worked with Brian and Nathan. Both were great to work with. Plenty of communication back and forth. Nathan did a really nice job cutting in the plastic around the piers. Would recommend them.
