"Everything went according to plan. Crawlspace insulation was replaced and closed space was sealed up. A air inducer was also installed. The environment is totally different down there now and is much closer to the temperature of the house. I kept my vapor barrier the same."

"Insulation Commandos insulated my garage drywall, and I had a great experience working with them. Tony was especially helpful in explaining the available options and recommending the solution that best fit my garage and specific needs. He was knowledgeable, professional, and even managed to fit me into his schedule on short notice, which I greatly appreciated."

"I contacted 6 other contractors to foam insulate a home addition that I am building. One gave me a price and then later told me he couldn't do it and gave my name to another contractor I had not interviewed and this contractor wanted to charge more. Another sent out a man who knew nothing about insulation and this rep told me only that he used to install pools had no tapes, etc.. James Ivey came out and it was clear that he knew his business. He measured up the work, gave me a fair price and completed the work and provided the data sheets for inspection. Work was done professionally, on time and no problem with inspection. After dealing with many other contractors, I can save you some time. Hire James and his company. He knows what he is doing. Passed inspection and MY inspection in a breeze."

"I recently had Home Shield install new insulation in my home, and I couldn't be happier with their work! From start to finish, they were professional, punctual, and efficient. They arrived right on time and completed the job in a timely manner without cutting corners. What really stood out to me was how clean they left everything. They made sure to clean up thoroughly after themselves, which is always appreciated. Additionally, their expertise was evident—they not only knew exactly what needed to be done but also took the time to explain what steps we could take to keep our home warm during the colder months. Overall, their excellent service and attention to detail exceeded my expectations. I highly recommend them"

"I had recently bought a house and wanted to know if my upstairs insulation was doing its job. I found Koons Crawls Space Solutions through Angie's List. Literally within minutes of requesting a quote, Tim got back to me. He was able to come out the same day and check out my attic insulation. He was by far the fastest to respond. Unlike the large well-known company that first gave me a quote, Tim gave me his honest opinion that my current insulation was fine and we didn't need more. He showed me how the big-name company was looking to make some money rather than address my personal needs. I still had him quote me what it would cost to do the same work the larger company quoted, and Tim's price was significantly less. I highly recommend Tim from Koons Crawl Space Solutions. He saved me thousands!"

Insulation questions, answered by experts

Combining insulation service with upgrades like HVAC improvements, air sealing, or roofing work in Raleigh can maximize energy efficiency and home comfort while saving on labor costs. Scheduling multiple projects together often streamlines the process. Fall and early spring are ideal times for these upgrades, and you may qualify for local rebates or federal tax credits, further increasing your return on investment.

Helpful?

In Raleigh, insulation service projects can reveal hidden costs such as the need for air sealing, mold remediation, or electrical upgrades, especially in older homes. Structural repairs or improving ventilation may also become necessary. If your home was built before 1980, addressing potential asbestos or lead is important. Permit fees for larger projects can add to expenses, so it’s wise to anticipate these possibilities before starting.

Helpful?

If your Raleigh home has high energy bills, inconsistent room temperatures, or drafts near windows and doors, it’s likely a good candidate for insulation service projects. Homes in neighborhoods like Five Points or Oakwood—especially those built before 1980—often lack modern insulation. Feeling cold or hot walls, or noticing ice dams in winter, are strong signs that an insulation upgrade can improve your home comfort and energy efficiency.

Helpful?

In Raleigh, most insulation service projects take between one and three days, depending on your home’s size and the specific areas being insulated. Attic or crawl space insulation is typically completed within a day or two, while wall insulation—especially if drywall removal is necessary—may extend up to five days. Factors like weather, accessibility, and contractor scheduling can also influence the overall project timeline.

Helpful?

For Raleigh’s humid climate, blown-in fiberglass or cellulose with R-38 to R-49 ratings are excellent for attics, helping to boost energy efficiency. Spray foam works well in crawl spaces or basements for air sealing, while rigid foam boards with vapor barriers help manage moisture. Choosing mold-resistant and fire-resistant materials, along with proper vapor barriers, is essential to protect your home and maintain long-term comfort.
