"GIC added insulation and air sealing in our attic. I had multiple bids and felt that GIC was the company that best understood what needed to be done to make our home more comfortable and energy efficient. The team was thorough and did the work quickly and efficiently. I was impressed with their attention to detail and I look forward to a much more comfortable home this summer."

"We had 1 inch of insulation in our attic. Hired the fellas at Green Star Energy to blow in insulation throughout the whole attic. I felt a difference immediately once the project had been completed. Our ac is getting a much needed break."

"Excellent work, competitive pricing and hard working staff! After initial consultation Mauricio gave me multiple options of insulation level for my attic to bring it up to date and/or blow in additional and that's what's I decided to go with. On the day of appointment their team got right to it and figured out best point of entry and only took a few hours to complete the job! They come with a special ruler indicator that verifies the insulation is to the level requested, then after a quick clean up they were on their way to the next job with another satisfied customer. Overall a great help and I've already booked them for some additional work in my basement as well! Would definitely recommend C4 insulation for all your home needs!"

"My experience with Victory Insulation went extremely well. They installed blown fiberglass insulation in my attic. The installation crew was very helpful and easy to work with. Since the install, my family has already noticed our hvac running a lot less within the last few months. I highly recommend working with Victory."

Before we started you could see the ceiling joists. We made sure this insulation was up to EnergyStar recommendations, R49 (about 18" of blown fiberglass insulation).

FAQs for insulation service projects in Dearborn, MO

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.
