Windows & Doors in Weymouth, Massachusetts

The Town of Weymouth requires a permit through the Building Division for any window or door replacement that changes the opening size, structural framing, or egress configuration. Like-for-like sash replacements typically don't need a permit but must meet current egress code. Properties in the Weymouth Landing or Old North Cemetery historic-overlay areas may need additional Historical Commission review for visible exterior changes.

Window-and-door costs in Weymouth sit a bit below Boston metro pricing and in line with the broader South Shore market. Standard vinyl replacement windows typically run $600–$1,000 installed per opening; wood or composite for historic-compatible installs are $1,400–$2,900 per opening. Entry door replacement is typically $1,900–$5,000 installed depending on material and sidelite configuration. Larger ranches with 12–20 openings benefit from quantity-discounted per-opening pricing.

Weymouth sits on the South Shore in Norfolk County, just south of Quincy — about 57,750 residents across roughly 24,500 housing units, with a median construction year close to 1957. The housing stock is dominated by post-WWII single-family Capes, ranches, and splits across North, East, and South Weymouth, with brick two-families in the original village centers, smaller pre-war stock near Weymouth Landing, and newer townhomes off Route 18.

Most local window-and-door work is full-frame ENERGY STAR replacement in 1950s–70s single-families where original wood or aluminum sash has aged out. Entry-door upgrades — often with new sidelite packages — are also a steady portion of the work, as is patio-door and sliding-door work on the area's many decks.

Weymouth is in National Grid electric territory, so homeowners qualify for the Mass Save weatherization program. Mass Save doesn't directly rebate replacement windows, but it heavily subsidizes the insulation and air-sealing work around window and door openings — typically rebated at 75%+ when surfaced through a free home energy assessment.

Note: the federal IRS 25C energy-efficiency tax credit (which previously offered up to $600/year for windows and $500/year for doors) expired for property placed in service after December 31, 2025. For Weymouth's mid-century single-families, the Mass Save air-sealing subsidy is now the primary available incentive alongside the long-term energy savings of ENERGY STAR-certified units.
