Robert Carroll, the owner, has 30 years of experience in the insulation and ventilation business. Attic Air has been in business since 1996 and specializes in insulating and ventilating residential homes. Attic-Air will come out free of charge to evaluate your home. Robert Carroll will be at every site to ensure a job well done and that you will be a satisfied customer. (No subcontractors used)

"It went really well. Robert Carroll really knows his stuff. Hire this guy. I say that without reservation of any kind. Don't look any further, believe me, I did. This is the smartest guy. He is honest, dependable, offers fair pricing, and his team can do all the work. I got several estimates from A+ rated insulation companies, but Robert was more knowledgeable than the other companies. He was the only one to point out that my soffits were not vented. Apparently, my house was built on the day no one was inspecting. The builder never cut open the soffits. That meant there was zero airflow going through my attic. The attic fan could run all day, but without air to move, it would not do any good. Only Robert noticed this and offered a solution to fix the problem! I asked some of the other A+ companies if they would vent the soffits and they all said they don't do that work, but they would be happy to add more insulation, which would not fix the problem if the attic was not vented."

FAQs for insulation service projects in Libertyville, IL

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.
