Full-frame and insert window replacements for Medford homes — proper flashing, sealed transitions, PVC trim, and energy-efficient glass for pre-war colonials, triple-deckers, and multi-family buildings. Google Guaranteed. 150+ five-star reviews.






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.

Posted on Bradford JonesTrustindex verifies that the original source of the review is Google. We had been in our home a long time and exterior was due for serious updates. Roof was from the early 90s, siding was peeling in layers, and the windows were old vinyl with seal failure and had no insulation. We kept putting it off until a neighbor recommended John. He spent over an hour walking the property with us on the first visit, pointing out things we hadn't even noticed, including a section where moisture had been getting behind the siding for years. He didn’t pressure us, just a clear explanation of what was going on and what it would take to fix it right. We ended up doing everything. Full roof, new siding, all new windows, and complete trim. The crew showed up early, kept the property clean (and cleaned up after), and communicated well throughout. When they found more damage than expected behind one wall, John called same day with pictures and options before moving forward. The transparency was both refreshing and important. It's been about a year and a half and everything still looks and performs exactly as it should. Heating costs dropped noticeably and was especially apparent this year. We live on a main street and the noise in our front bedrooms is gone. The house legitimately looks like a completely different property. If you're in the north shore area thinking about exterior work, get a quote and talk to John. You'll see the difference.Posted on Roman CooperTrustindex verifies that the original source of the review is Google. We have a big old farmhouse out in Boxford with a roof that probably should've been replaced five years ago. Finally pulled the trigger and called D&G Exteriors. John came out, looked everything over, and gave us a quote that was fair and detailed. Crew did the whole tear off and install in three days. No complaints at all.Posted on Parker SimmonsTrustindex verifies that the original source of the review is Google. I’m so impressed with the service I received.

Medford homes range from 1700s colonials to mid-century builds to modern renovations. The right window approach depends on the home’s age and frame condition.

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.
Depends on your existing frames. If solid, square, and dry — inserts save time and cost. If there’s rot or water damage, which is common on Medford’s pre-war homes, full-frame is the better long-term investment. We inspect and recommend honestly.
Yes. Medford requires building permits for window replacement. We handle the application, inspections, and code compliance.
Andersen, Marvin, and Pella for premium fiberglass and wood-clad. Harvey and Mathews Brothers for high-quality vinyl. We help you choose based on the home, your energy goals, and budget.
Most whole-home projects take 2–5 days. Individual replacements can be done in a day. We protect interiors, flooring, and landscaping throughout.
Yes. We coordinate across units, schedule work to minimize disruption to tenants, and can phase the project if needed. Exterior trim work is done consistently across all floors for a clean finished look.
Yes — especially replacing original single-pane or early double-pane windows. Modern low-E coated, argon-filled units significantly cut heat loss in winter and heat gain in summer. Medford’s older homes often see the biggest improvement.
