I was impressed with the speed of the installation, but the mess that was left was inexcusable. Nails, insulation, and trimmings were left everywhere in the yard. I pointed this out, but their solution was to bring a leaf blower and blow everything around. Useless.

It was excellent! The installer was punctual and had the work done in half the time that it would have taken me with a higher quality insulation than I would have purchased at a home improvement store. The actual cost was less expensive than if purchased at the store as well.

Insulation questions, 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.

Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.

Most insulation lasts 15 to 20 years, but it really depends on the type of insulation. Spray foam is a permanent insulation material that can last up to 100 years. Fiberglass and cellulose typically settle, shift, or deteriorate around 15 years. Once your insulation reaches the 15-year mark, it's time to check it for signs of needing to be replaced.

Insulating your basement walls offers numerous advantages that make the project well worth it. By adding insulation, you can reduce the chances of moisture damage to the house's structure and lower the odds of mold growth. You'll also add comfort to the space by reducing temperature swings and increasing your home's energy efficiency, potentially reducing your energy bills to earn your investment back.

All garage doors, particularly newly installed models, add value to your home. Higher-quality and higher-priced doors increase the ROI, so a well-insulated custom garage door increases the value of your home more than a poorly-insulated stock model. Updating a garage door boasts the second-highest home improvement ROI, at nearly 95%.
