When Should Insulation be Upgraded or Replaced?

Draftiness, a damp attic (identifiable by mold or mildew in the attic), water leakage in ceilings or walls, rat or mice droppings found in the attic or elsewhere in the home, or unusually high energy bills are all key indicators that insulation is likely in need of an upgrade.

Secondly, if insulation appears compressed down, damp, or bent in any way, this is usually a sign it is in need of a replacement.

When checking insulation in your attic, use a yardstick to check the depth. The average home needs up to 19 inches of fiberglass attic insulation for maximum energy efficiency. It’s also important to remember that just because there is insulation in one part of the home, there still may be other areas of the house that do not have insulation.

For larger concerns or a more in-depth evaluation, contact an insulation contractor or expert for a full house energy assessment. This typically involves taking an infrared photo of the home and is one of the simplest ways to determine how energy efficient a home is. Alternatively, if the home is relatively new, the homebuilder is another good resource for this information.
