Insulation questions, answered by experts

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.

Duct insulation typically has a long lifespan, often exceeding 10 to 15 years. However, periodic inspections are crucial to check for signs of damage, wear, or deterioration. If you notice issues such as torn or water-damaged insulation, it may be time for replacement or repairs. Additionally, consider upgrading insulation if you're looking to improve energy efficiency or enhance your HVAC system's performance.

Regular inspections for moisture damage, pest infestations, and proper R-value performance help maintain efficiency.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.
