Seal in $avings Year-Round with Insulate Colorado

Properly insulating and sealing a home can help reduce your heating and cooling costs by up to 20% or up to 10% on your total annual energy * and make your home more comfortable. Xcel Energy has partnered with the Governor's Energy Office's Insulate Colorado program to offer cash rebates to qualifying homeowners in the Xcel Energy service area.

The rebates will be issued for the installation of either attic or exterior wall insulation and basic air sealing measures, performed by an Insulate Colorado approved contractor (do-it-yourself projects are not eligible).

The rebates cover 20 percent of the total cost of insulation and air sealing upgrades or $300, whichever is less. Rebates will be awarded on a first-come, first-served basis until program funding is exhausted. This is a limited time offer, so contact an approved contractor today!
