"The company rep came out as scheduled and conducted a thorough and professional estimate for the added insulation. Then the installers came out and again did an outstanding job adding insulation to our attic. They worked well as a team and did an excellent job."

"Matthew did a thorough quote at my house shortly before Thanksgiving. Matthew was very professional, on-time and friendly. The technology was impressive as you could see the ?cold spots? around my attic space. I plan to execute the job after the holidays. I highly recommend Matthew and Insulation Commandos if you need any insulation related work."

"Eddie fully explained the benefit of the planned level of insulation for our attic, uses quality Owen's Corning fiberglass blown in insulation and recommended adding an roof vent attic fan to remove heat/moisture in the summer and moisture in the winter. Currently, we have passive eve vents and roof ridge vent. Cooling inside of the roof with air flow should help extend the life of the shingles by removing stagnant hot air. We chose an electric roof vent fan rather than solar because of the # of cloudy days in our area and humidity. Everything was done quickly on scheduled time, all contacts were professional, kept our home as clean as possible and swept up loose insulation. Pricing was very competitive plus we qualified for TVA energy rebate."

Spray foam insulation has the power to improve energy efficiency by up to 30 percent because of its ability to combat air infiltration. While this can mean savings for your home or business, it can also help with seasonal allergies, indoor air quality, and reduced mold. However, the efficacy of your insulation is largely dependent on the capabilities of the installers. Making mistakes during installation can reduce the benefits you receive, which is why it's always best to hire a professional. \n

"When I had originally contacted Bia Insulation I was pleasantly surprised at how quick and easy the process was to set up my appointment with them. Once everything logistically was taken care of, insulation install process came and went in a swift manner. I was highly impressed with not only how professional but personable Jeremy was. He was my go to guy from start to finish and that meant a lot to me. Having the one point of contact throughout the whole process was breathe of fresh air. As far as savings go, my wallet and my wife are VERY happy. We noticed savings on our bill within the first couple of months."

Insulation FAQs, answered by experts

Insulating your ducts offers several benefits, including:

  • Improved energy efficiency: Duct insulation prevents energy losses, reducing heating and cooling costs.

  • Cost savings: Lower energy bills make insulation a cost-effective investment.

  • Environmental benefits: Enhanced efficiency reduces your carbon footprint.

  • Consistent comfort: Insulated ducts help maintain a stable indoor temperature.

  • Better indoor air quality: Reduced allergens and pollutants improve air quality.

Reduces energy costs, improves comfort, and prevents ice dams in winter.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.
