Attic Insulation in Maryland & Washington, DC

Q: 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 towards the total thickness, unless it needs to be removed.

Q: Should I remove old attic insulation before adding new?

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

Q: 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. (Make sure to find the source of the moisture first, so 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.

The average home loses 85% of its heat through the attic. Even the strongest HVAC system will struggle to beat that statistic, so this oft-forgotten room needs a little extra attention. Attic insulation alone can reduce your energy costs by as much as 50%.

Attic Insulation FAQ

How much insulation should I have in my attic?

Every insulation material has its own density and R-value. Your climate also plays a role in your choices. Washington, DC and Maryland attics should have an R-value of 38 to 60.

Should I remove old attic insulation before adding new?

It’s possible to add new insulation over old insulation, but it depends on the condition of your existing material. A contractor can inspect your insulation to detect leaks, infestations or asbestos and determine if it needs to be removed.

How long does insulation last in an attic?

Well-installed insulation only needs to be replaced every 80 to 100 years. You’ll lose much of that life span through negligence, so make sure your insulation and roofing are regularly inspected for leaks and infestations.

When should I replace my attic insulation?

Rising energy bills are the first sign of inadequate insulation. If your bill skyrockets without a significant change in your HVAC usage, it could mean you have air leaks due to poor insulation.

You should also replace your insulation if it gets wet or moldy. If you’re in doubt, Accurate Insulation can perform an inspection and provide expert advice.
