Weatherization Assistance Program (Massachusetts)

Massachusetts weatherization provides home energy efficiency services for households eligible for HEAP. The HEAP application also serves as the weatherization application.

Who can apply

['Households meeting Massachusetts HEAP eligibility.', 'The local weatherization agency determines the work suitable for the property.']

What help is available

Energy efficiency improvements determined by the local agency, followed by inspection of completed work. This is a home service rather than spending money paid to the household.

Documents to prepare

Have the HEAP application information ready and note drafts, insulation concerns and heating problems. If renting, ask what property owner paperwork is required before arranging work.

How to get started

  1. Find the agency serving your town through the state weatherization page.
  2. Submit a HEAP application online or through the local energy assistance agency.
  3. Ask to be considered for weatherization and arrange the property assessment.

After applying

Ask about the assessment queue, access arrangements and approved work. Keep the agency’s inspection information and report any concern about completed work to it.
