Windows

$1-$12 per square foot

Replacing old, leaky windows with energy-efficient windows can do more than save energy. It can also improve indoor air quality, reduce drafts and condensation, decrease outside noise and increase curb appeal.

If you own an individual condominium unit, townhome, duplex, triplex or fourplex in Washington, view available cash incentives for windows upgrades.

Projects must be installed in accordance with the specifications outlined in the Specifications Manual.

To get started on your energy-efficient upgrade follow the steps below or contact a program representative.
