Your attic floor insulation is important to keep your entire home protected. The attic is where a lot of heated or conditioned air escapes your home, so keeping your insulation in good condition is critical. Here are four signs it’s time to replace your attic floor insulation.

1. Water Damage

If you have a roof leak, appliance leak, or another water breach, your insulation is vulnerable to damage. Water can wear away at the insulation and lead to mold growth, which can be unsafe. If you notice water damage in your attic insulation, it’s time to replace it.

2. Drafts

Your attic insulation — especially spray foam insulation — should not be letting any noticeable drafts through. If you walk by your attic entry point and notice a draft, there’s a good chance there is a problem, and you may need to replace the insulation.

3. Dirty Insulation

Insulation in good condition should not have any dirt or dark spots visible. If you notice your attic insulation has become discolored or has visible dirt or marks, it’s probably time for a replacement. 

The appearance of dirt can also signify that your insulation has been disrupted by unwanted critters like insects or rodents, which can become a real problem for your home if not addressed.

4. Odors

Insulation should not have much of a smell. If you notice an odor coming from your insulation, that’s a strong signal that it has water damage, an infestation, or another problem. Attic insulation with odors should be replaced immediately, as odors can often mean that mold and allergens are making their way into your home.

Consider Replacing Your Spray Foam Insulation
