"These guys are the best. I had a complicated installation and they did an excellent job. The job went just as they explained it would. The area was left clean and there were no surprises when It came time to pay the bill. I would highly recommend them to anyone looking for insulation installation."

"So happy I went with USA Insulation. After learning about foam insulation, I knew it was the right option for my house. They insulated my walls and attic in a day and a half, and I could feel the difference right away."

"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."

"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!"

"Jimmie was professional, friendly and knowledgeable. Of the estimates and recommendations I received for mold remediation in my crawlspace, I thought Jimmie's approach seemed the most logical and thorough. Pricing was fair, and the service was prompt with regular communication from him and his team about progress and next steps. He even performed an extra preventative measure that wasn't included in the estimate. I highly recommend this company."

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.
