Bundle up your home to save money and significantly increase comfort.

Designed to keep your home warm in the winter and cool in the summer, properly installed insulation can significantly lower your electricity bill. There are several common types of insulation – fiberglass, cellulose, rigid foam board and spray foam – all of which can help you save electricity and money. When adding insulation, make sure you know the R-value of the product you are considering. Used to measure the insulation's thermal performance, a higher R-value will deliver more insulating power.

Getting Started

Insulation may be self-installed by homeowners or installed by a contractor. Customers interested in using a contractor can find a participating contractor using the Washington Participating Weatherization Contractors list. When choosing to use a contractor, review the Incentive Application with them to determine eligibility requirements, incentive qualifications and review the list of required documents to submit for an incentive.

Incentive application and required documents must be received within 90 days of the work completed date. Insulation must be fully installed prior to submitting an incentive application. Incentive checks are issued within 45 days of receipt of the completed and approved application. Checks are only payable to the account holder or property. Incentives are not to exceed the project cost and are limited to the square footage of the qualified area of the home (wall, floor or attic). Work may be inspected for compliance. Incentives are subject to tariff approval and may change with 45 days notice. Additional terms and conditions may apply.

To ensure your home is eligible for an incentive and below the maximum insulation depth requirements, please use the insulation depth calculator. Prior to your contractor recording measurements, take a peek in your attic and do it yourself!
