Q: What maintenance is suggested for attic insulation?

• <div><p>Periodic checks for moisture or pest issues ensure consistent performance.</p></div>

Q: Is it worth it to remove old attic insulation?

• <div><p>The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.</p></div>

Q: How long does it take to install or upgrade insulation?

• <div><p>The time required for insulation installation can range from a few hours to a few days, with most projects taking 1-3 days to complete. The final duration depends on the project's size and complexity, the area size, and the type of insulation being installed.</p></div>

Q: Do I need to air seal my attic before installing insulation?

• <div><p>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. </p></div>
