Weatherization Assistance Program (Delaware)

Delaware weatherization provides free energy-efficiency services for qualifying homes. The Energy Coordinating Agency handles statewide intake.

Who can apply

Eligibility depends on household size and income. Homeowners and renters can apply; service priority and annual funding affect the waiting list.

What help is available

An energy audit selects conservation work such as insulation and air sealing. This is not a general home-repair program or a routine window replacement service.

Documents to prepare

  • Household income and member information.
  • Property address and ownership or lease records.
  • Any owner permission or other property evidence the provider requests.

How to get started

  1. Arrange intake

    Call Energy Coordinating Agency at 302-504-6111 through the DNREC WAP page.

  2. Confirm the document list

    Bring the requested records and discuss the home’s heating and safety concerns.

  3. Arrange audit and contractor access

    An approved home is assessed before recommended work and a final quality inspection.

After applying

An adult must be available for contractor visits. DNREC says households not served within 12 months must reapply annually.
