"Chris with St. Louis Insulation went above and beyond, he dispatched Brian out to inspect our insulation as we thought it was getting wet on the same day we called. Ultimately it was determined we did not have an issue. If an issue ever does come up we will be calling Chris with St. Louis Insulation. Thanks, Russ"

"Well, the was too much on the second floor but Aladdin solved that with blown insulation. I look forward to the cool savings in the summer and warm savings in the winter. The house has not added insulation since it’s manufacture in 1989. We have been here for 4 years. Should have done it four years ago. Thank you Aladdin!"

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.
