Why Medford Homeowners Choose D&G for Windows

Medford’s windows cover every era — original wood double-hungs on West Medford colonials, aluminum storms on mid-century homes, early vinyl replacements already fogging on 1990s-era installs. On triple-deckers, you might find three different window generations in the same building. Whatever you’re replacing, the work behind the frame matters as much as the window itself.

Common Questions About Window Services in Medford, MA

How much does window replacement cost in Medford?

Most whole-home projects range from $25,000 to $65,000+ depending on window count, frame type, and installation method. Triple-deckers and multi-family buildings with more units and openings will be higher. Detailed estimate after on-site measurement.

Most whole-home projects take 2–5 days. Individual replacements can be done in a day. We protect interiors, flooring, and landscaping throughout.
