"I hired Carolina Crawlspace Services to completely clean out the crawlspace under my townhome, remove all of the old insulation and vapor barrier, and install new insulation along with a stronger, higher-quality vapor barrier. I received estimates from four other companies and chose Kyle and Carolina Crawlspace because their pricing was competitive, included more work than the others, and was slightly lower overall. Kyle communicated clearly throughout the entire process, arrived on time, and did a fantastic job. The quality of the work and professionalism exceeded my expectations. I would highly recommend Carolina Crawlspace Services to anyone who needs crawlspace work done."

"GreenServe blew insulation into our attic and also put down a vapor barrier in our crawlspace. The crew had to work under very difficult weather conditions and did not complain at all; they were very friendly and professional and did exactly what I expected for a reasonable price.."

"My family and I have been living in an RV for over a year now, due to hurricane Florence. It has been a nightmare dealing with shady, lazy and difficult tradesmen but doing business with Mitch has been the easiest thing in this whole process. I called him on a Friday to insulate my entire home and he was completely done by the following Tuesday, before lunch time. He s extremely friendly and an excellent communicator. He kept me in the loop the entire time and showed up when he said he was going to. He does quick work but he is very proficient and he actually cleaned up after himself, which seems to be completely unheard of. We called around to multiple businesses for spray insulation and Mitch is by far the BEST price you will find out there. He even gave me a really good discount because I think he s just a nice guy. I highly recommend Mitch. He will make your life easier in regards to upgrading your home."

"I would highly recommend Prime Energy!! Rich (Sales Mgr.) was exceptional from the first contact to the last experience. The crews were top notch in all they did and finished a large project in just 3 days (removal & installation). Very pleased with the final results and the temp difference in our attic has gone from 150 down to upper 70 s. I would definitely recommend this type of insulation and Prime Energy to do it. Very Satisfied Customer, Jason C."

"I was considering foam insulation for the last two years and got several quotes from different companies but it was always unaffordable till I came across NC foam Pros, the price was very affordable so I decided to try their service on rental home first , The process was smooth , promptly responded to my questions .Had same week appt, and the difference the foam insulation made was very noticeable, the house was old built in 1958 and barely kept heat now it feels very comfortable, so this week we gave them three more jobs and I will consider them for any future insulation job because I can Finally say I found a good deal without surprises"

Insulation FAQs, answered by experts

The cost to install a radiant barrier ranges from $700 to $2,800, depending on the size of your roof and the type you choose. Most people pay an average of $1,700 to install a radiant barrier. Foil options, both single- and double-sided, cost between $0.10 and $0.90 per square foot, while spray-on options start at $0.60 and go all the way up to $1 per square foot—which can add up quickly.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Minimal maintenance is required, though regular inspections to ensure insulation hasn't shifted or deteriorated can improve performance over time.

If you’re a savvy DIYer around the house, own the basic tools, and have enough time on your hands, you can definitely install fiberglass insulation yourself. Doing the work yourself will certainly keep overall insulation costs down. However, if you’re not confident in your handy skills around the house, call in a professional.
