Common Questions

Homeowners in historic districts like Beacon Hill or Back Bay should expect to pay 20% to 40% more. The Boston Landmarks Commission often requires specific wood-clad materials and muntin patterns, which can increase per-window costs to between $1,800 and $4,500.

Boston uses a 'short-form' permit for windows, which costs a base fee of $20 plus $10 for every $1,000 of the project's value. For a typical $20,000 project, the permit fee would be approximately $220.

Yes, through the MassSave program, Boston residents can qualify for rebates ranging from $125 to $500 per window in 2026, provided the units meet specific Energy Star U-factor and SHGC ratings.

Triple-pane windows are increasingly recommended for Boston's harsh winters. While they add roughly 15-25% to the material cost, they can reduce heating energy waste by 25-40% compared to aging double-pane units.
