Rebate Program Participation

Steps to Participate

After the eligibility requirement has been met, the following steps are applicable:

After your initial audit is completed you will receive a list of eligible measures for your home.

We offer a courtesy list of area contractors available in our Chehalis, and Morton offices, or by downloading the weatherization packet below. While not required, you are encouraged to get more than one bid to fully research the options available to you.

A bid review appointment can be requested by customers who are considering multiple bids and would like assistance in comparing bids.

A verification of the measures installed may be conducted by a member of our energy services team to ensure the installed measure(s) meet program specifications (see below).

Payment of the verified incentive is made to the chosen party.

  • Please note that if you choose to do the work yourself or have an installer other than one on our provided list do the work, you must complete and submit the weatherization homeowner acknowledgement form, and all receipts and/or paid invoices for verification. The incentive will be paid to the homeowner after a measure verification appointment has been completed.

The Conservation Participation Agreement must be completed prior to receiving a rebate. If the homeowner and account holder are different parties, both parties must complete and submit the conservation participation agreement before an incentive can be processed. This form is available by using our online form or by completing the program packet, both found below.
