Our Attic Insulation Process

01

Energy Assessment

We measure existing R-value, check for air bypasses, and assess ventilation to develop the right insulation strategy.

02

Air Sealing

Before adding insulation, we seal gaps around penetrations, top plates, and recessed lights that allow conditioned air to escape.

03

Insulation Installation

New insulation is installed to the recommended R-value for your climate zone — R-38 to R-60 for most U.S. attics.

04

Verification

Final R-value is confirmed, ventilation is verified, and all work is documented for rebate and tax credit applications.

Attic Insulation FAQ for Washington DC Homeowners

How often should Washington DC homeowners get attic insulation?
Given Washington DC's hot, humid summers averaging 88°f+, most homeowners benefit from attic insulation at least once a year. Spring pollen coating all exterior surfaces often makes spring or fall the optimal time to schedule service.
What home types in Washington DC most need attic insulation?
Capitol Hill and Georgetown row houses and Colonial revival homes in Maryland suburbs are the most common home types in Washington DC and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
How much insulation do I need in my attic?
Most U.S. climate zones recommend R-38 to R-60 for attic insulation. The DOE Zone Map determines the recommended R-value for your specific location.
What type of insulation is best for attics?
Blown-in fiberglass or cellulose is most common for existing homes — it fills irregularly shaped spaces and achieves depth quickly. Spray foam is used for unvented attic assemblies. Batts work well in new construction.
How much will I save on energy bills?
Homes with inadequate insulation can save 10–50% on heating and cooling costs after proper insulation. The average homeowner sees $200–$600/year in savings depending on climate and existing conditions.
Are there rebates for attic insulation?
Yes. The Inflation Reduction Act provides a federal tax credit of 30% (up to $1,200) for insulation improvements. Many utilities offer additional rebates of $0.10–$0.20 per square foot.
