How Often Do I Need to Replace the Insulation in My Attic?

If you notice your heating or cooling bill skyrocketing, it may be time for you to change your attic insulation. There are a few different signs that tell it’s time to have your insulation replaced.

How Often Do I Need To Replace Insulation in My Attic?

Standard insulation starts to degrade and start peeling from walls after about 15 years. If you have an older home, chances are the attic insulation is the same insulation that was installed when the house was built.

Insulation should also be replaced, in some cases sooner than 15 years, if it is no longer doing its job properly. You’ll know it needs to be replaced if there are insulation leaks or if it is peeling from the walls.

Signs My Insulation Needs to Be Replaced

If you don’t know how old your attic insulation is, there are a few signs that can tell you it is time to have your insulation replaced.

  • Issues With Heating Or Cooling – If you have to blast the heater or the AC at all times to keep your house at comfortable temperatures, this is a good sign that the insulation is failing to trap the cold or hot air and should be replaced.
  • Drafts – If you notice cool drafts, this means your insulation isn’t properly keeping the air outside from entering the house and needs to be replaced.
  • Mold or Wet Insulation – If your insulation is continually damp or you have noticed mold on your insulation, you should have the insulation removed, your attic inspected and repaired, and then new insulation installed.

Types of Insulation

There are a few different types of insulation you can choose from.

  • Batt Insulation – This is probably the most common type of insulation. It is made from fiberglass or natural fibers and reliably captures (or keeps out) heat.
  • Spray Foam Insulation – Spray foam insulation is insulation that is sprayed into an area and then expands to fill the area. It is very effective at insulating, especially if you are insulating hard-to-reach areas.
  • Reflective Insulation – This type of insulation reflects heat or cold and is usually made from reflective materials or cardboard.
