Siding in Wilmington, Massachusetts

What applies to this work in Wilmington, Middlesex County: Mass Save, rebates and financing, and the permit. Then the contractors serving the town.

30 contractors serving Wilmington.

Is Wilmington in Mass Save?

Partly. Wilmington is a municipal light plant town: its electricity comes from the Reading Municipal Light Department, and light plant customers are outside Mass Save's electric program. National Grid, an investor-owned gas company, also serves the town, so a home with a National Grid gas account can use Mass Save through it.

For weatherization, a National Grid gas account is enough, even one that only heats water. A home with no gas service uses the light plant's own programs.

Wilmington is on the state's list of municipal light plants; Mass Save in municipal light plant towns has the full decision tree.

Rebates and financing for new siding in Wilmington

Mass Save doesn't pay for the siding itself: its insulation and windows offers cover insulation, air sealing and windows, and siding is not on the HEAT Loan's list of eligible measures.

The insulation can be covered through a National Grid gas account: after a Home Energy Assessment, Mass Save pays 75 to 100 percent of approved insulation and air sealing. Book the assessment before the old siding comes off, while the walls are open. Homes with no gas service use the light plant's own weatherization programs.

Do you need a permit for new siding in Wilmington?

Plan on one. Residing is not on the Massachusetts building code's list of permit-exempt work, and the Wilmington Building Department settles the borderline cases. 54% of Wilmington's homes were built before 1980 (Census ACS 2018-2022), and work that disturbs paint in a home built before 1978 has to follow the lead-safe renovation rules.
