"Matt Rich took the time to explain attic and crawl space insulation. I never really knew much about all the leaks that are in our homes. We had a little miscommunication near the end of the day, but it was all taken care of. He has a good crew working for him."

"One of the best most professional companies I have ever had to work with. On time! Price when the work was complete was the exact price quoted. Very reasonable. Gave me an estimate on the phone based on square footage. I highly recommend them to anyone. Kevin took and returned all my calls and answered all my questions. Austin, Gunnar and Robert came out and finished the job in 2 1/2 hours, they were very professional and courteous and did a great job!!!"

"I had Crawlspace Kings come out for basement waterproofing and they seriously exceeded my expectations. From the first inspection to the final walkthrough, everything was explained clearly and professionally. They took the time to show me exactly where the moisture issues were coming from and laid out a solid plan to fix it. The crew was on time, respectful, and worked hard the entire time. You can tell they actually care about doing the job right, not just getting in and out. After everything was finished, my basement feels completely dry and I have so much more peace of mind knowing it’s protected long-term. If you’re dealing with moisture, leaks, or just want to prevent future problems, I 100% recommend Crawlspace Kings. Super reliable, honest, and great quality work."

FAQs for spray foam insulation projects in Knoxville, TN

Local and federal rebates are available for insulation installation, which can significantly reduce your overall costs. Many utility companies offer incentives or rebates to homeowners who improve their home's energy efficiency. Contact your local energy provider or government agencies to learn about available programs in your area, and consult with a professional insulation installer to maximize your savings.

It's not necessary to remove old insulation before adding new insulation, as long as the existing insulation is in good condition—dry, free of mold, and not damaged. Adding new insulation on top of old insulation can improve your home's energy efficiency by increasing the overall R-value. However, if the old insulation is wet, moldy, or damaged, it's best to remove it before installing new insulation to prevent potential health risks and ensure optimal performance.

Insulating a house takes between five and twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the size of your home, the type of insulation, and the accessibility of the areas being insulated. Keep in mind that projects may take longer if old insulation needs removal, if there's a larger square footage, or if spaces are difficult to reach.
