"I was happy with the job that was done. It provides insulation plus a vapor barrier. He put in a radiant barrier. It looks almost like tinfoil. They crawled around under the house installing it. It insulates better then conventional insulation. My house is warmer when it is cool and cooler when warm."

"Attic Professionals was awesome to work with and highly recommend their business for anyone looking for attic work. We hired his business to replace the insulation in our attic after I took care of a rat issue. We needed all the insulation and droppings removed, cleanse, and replace. Attic Professional crew were diligent with making sure the interior of our home was protected covering the walls and floors to remove the old insulation and did a great job installing the new insulation. Thank you for great service!!!!!!!!"

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.
