"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."

"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

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.

It is possible to insulate your walls without removing drywall, but it’s not a good idea to attempt the work yourself. A professional can use blown-in insulation or spray foam insulation to fill wall voids without opening up the walls, and the option they use typically depends on your climate and whether or not there’s insulation in your wall already that can remain in place. Spray foam insulation costs more and isn’t always a viable option, but it’s a better insulator. Call in an expert to help decide which is right for you.

The ideal temperature for your garage in the winter is between 40 and 68 degrees Fahrenheit. Maintaining a minimum temperature of at least 40 to 50 degrees is crucial to prevent pipes, liquids, and other items from freezing. Low temperatures can also drain your car battery, so keeping the garage stable is vital for your vehicle. While the lower end of the range protects your belongings, the higher end is based on your personal preference for a comfortable space. If you struggle to keep the temperature from dropping below 40 degrees, consider installing a garage heater.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.

Yes, brick houses are better insulated, because the bricks slow down the passage of air from the outside to the inside and vice-versa. This helps to stabilize the internal temperature of the home. When combined with proper residential insulation, brick houses are more efficient and better insulated than other types.
