Attic Insulation FAQ

How much insulation should I have in my attic?

R-38 to R-60 insulation is recommended for attics in Maryland & Washington, DC. Each type of insulation material, whether it’s fiberglass, spray foam or another option, has a different R-value per inch. Your attic would need a different thickness of insulation, depending upon the type used. Your existing insulation may count toward the total thickness unless it needs to be removed.

Should I remove old attic insulation before adding new?

You can add new insulation on top of old insulation that is still effective and undamaged.

If you’ve had a roof leak, this can wet the insulation, compact it and render it ineffective. Hidden roof leaks can also cause significant property damage, including wood rot and mold growth.

If your home is older, it may have vermiculite insulation, which contains hazardous asbestos. It’s typically best to leave this insulation undisturbed — homeowners should never disturb suspect insulation.) Call in our expert insulation contractors to evaluate whether your old insulation should be removed or can remain.

How long does insulation last in an attic?

When properly installed, attic insulation can last 80 to 100 years. We recommend that Maryland & Washington, DC, homeowners also consider attic sealing for the ultimate home energy efficiency. Air sealing drastically reduces air infiltration into your attic. To ensure proper ventilation and avoid damaging moisture or condensation, the attic roof should be equipped with ridge vents at the peak and inlet soffit vents below the roof’s edge.

When should I replace my attic insulation?

Replace your insulation if you’re noticing inconsistent temperatures throughout your home. Your insulation could be damaged, or it may have settled excessively due to a shoddy installation. This means you’re likely using your HVAC system more to keep your home comfortable, which is yet another sign it’s time to have your insulation evaluated.

If your energy bills are increasing, you may need insulation replacement or additional attic insulation added. Boosting energy efficiency with insulation will bring your energy bills under control.

Infestations of insects or mice can make a mess of your insulation. Wet or moist insulation should be replaced to avoid property damage. Ensure you find the source of the moisture first so that it can be corrected. The cause might be a roof leak or a poorly vented attic.

Drafts in your attic and home living areas can also mean your current insulation is not doing its job and should be replaced.
