💬What People Actually Paid
Community❓Common Questions
Yes. Homes in districts like Beacon Hill or Back Bay often require custom wood windows to match architectural standards, which can drive per-unit costs to $2,500–$4,500. Additionally, a long-form permit ($50 base + $10 per $1,000 of cost) is typically required for these structural or aesthetic alterations.
Through the Mass Save program, Boston residents can qualify for rebates of approximately $75 per window when upgrading to ENERGY STAR Most Efficient certified units. Homeowners may also access the HEAT Loan, which offers 0% interest financing up to $25,000 for energy-efficient improvements.
For standard replacements that do not change the window size or egress, a short-form permit is required, costing $20 plus $10 for every $1,000 of the project's estimated value. For a typical $15,000 project, the permit fee would be approximately $170.
Yes. Contractors in the Greater Boston area often offer volume discounts. While a single window replacement might cost $1,000–$1,500 due to mobilization fees, a whole-home project of 15+ windows typically brings the per-unit cost down to the $750–$950 range for standard vinyl.
