The Town of Arlington Inspectional Services requires a permit for any window or door replacement that changes the opening size, structural framing, or egress configuration. Like-for-like full-frame replacements in the existing rough opening typically don't need a permit but must meet current egress code — relevant on older two-families where original bedroom openings can be undersized. Arlington has an active Historical Commission for properties in the local historic districts (notably around Pleasant Street and the Jason Russell House area) where visible exterior changes are reviewed. Pre-1978 housing — most of East Arlington and large parts of the Heights — falls under federal lead-safe RRP rules, adding $50–$150 per opening.

Window-and-door pricing in Arlington runs in the upper inner-128 band — below Cambridge and Somerville on per-opening rates but above the outer 128 suburbs because of access constraints and the older stock. Standard vinyl full-frame replacements typically run $700–$1,200 per opening installed; mid-grade composite or wood-clad units run $1,500–$3,200 per opening. Entry door replacement is typically $2,300–$5,200 installed depending on material. Parking-permit and staging coordination can add several hundred dollars to project mobilization.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential window & door installation work; ask for the registration number and check it before paying a deposit.
