"Met Mike, had a nice visit on my front porch. I accepted his proposal and his men came to install the insulation. I made a pathway for his men s access, showed them the area to be done. A few hours, they were done. They cleaned up after themselves."

"Alpha insulation is a good choice. Their installation was great. The guys cleaned up all their mess. Which is a plus for me. Miguel was easy to talk to. I told him what I wanted done to my house and he gave me a great price for what I asked for. So I hired him. I would recommend alpha insulation to friends and family."

"Geovany and his team did an amazing job at my house cleaning attic removing all debris lid insulation, sanitizing and air sealing attic, installing new insulation and radiant barrier. Job was done in a clean and professional manner. Team was polite and professional. I would recommend Fibers Insulation to anyone looking to upgrade or replace their insulation or just looking to add radiant barrier to their attic for a cooler more energy efficient home."

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.
