When to Replace Old Insulation

 

Insulation is the unsung hero of any home, silently working to keep conditioned air inside and energy bills low. But insulation doesn’t last forever, and there comes a point when it needs to be replaced with new, up-to-date insulation. When should that happen? The answer depends on a few factors.

Whether you have attic insulation or cellulose insulation, both can lose their effectiveness over time. The key signs that it’s time to replace insulation include:

Mold and mildew growth. Insulation that’s water damaged will no longer be able to regulate indoor temperatures, and it’ll be vulnerable to pests who find shelter within the material.

Pests and rodents. It’s a common problem for rodents to tear apart and nest in old insulation, which can be especially damaging to open-cell cellulose.

Cost vs. Efficiency: Attic Insulation Materials Compared

If you notice rodent droppings or nesting materials in your attic, it’s probably time to remove and replace insulation. This is a crucial step in preventing health problems, as pests can spread harmful bacteria and allergens throughout the home.

Old insulation can also deteriorate over time due to moisture and pests, and it’ll no longer be effective in regulating the indoor temperature. This can lead to high energy bills and uncomfortable rooms, and it’s important to act quickly before problems escalate.

It’s generally better to add an additional layer of insulation over existing insulation rather than removing and replacing it altogether, depending on the condition of the older insulation. This is a cost-effective option, and it’s often possible to achieve a higher R-value with this approach.
