Cape Ann homes take a beating from salt spray, harbor winds, and driving rain. A lot of older windows in Gloucester — from the sea captains’ houses downtown to the cottages along Bass Rocks — leak air, rattle in storms, and drive up heating costs. When we replace windows here, we focus on what happens around the window just as much as the window itself.
What Our Clients Say

Whether you’re doing a full window replacement on a Rocky Neck waterfront home, swapping out drafty double-hungs near Stage Fort Park, or upgrading a few windows in East Gloucester — we handle measuring, ordering, installation, trim, and cleanup.
It depends on the number of windows, material, and the condition of the frames and trim around them. Full-frame replacements typically range from $800 to $1,500+ per window installed. Homes that need extensive PVC trim work or structural repairs around the openings will be on the higher end. We quote after measuring on-site so there aren’t any surprises.
Fiberglass frames from manufacturers like Andersen, Marvin, or Pella are the top performers in coastal environments — they’re dimensionally stable and handle salt and moisture without expanding or contracting. For a more budget-friendly option, vinyl windows from Harvey or Mathews Brothers still perform well in Gloucester’s conditions. We’ll help you choose based on your home’s exposure and budget.
We install head flashing and sill pan flashing at every opening and tie into the home’s weather barrier so water drains out instead of getting trapped in the wall cavity. Most of the water intrusion we see in Gloucester started with an installer who skipped the flashing. It’s the single most important detail in a coastal window job.
Yes — we install cellular PVC trim on every project. It won’t rot, warp, or break down in salt air the way wood does. It holds its shape, doesn’t require painting, and gives a clean finished look that lasts. Most Gloucester homes with wood trim around their windows are already showing signs of failure, so the upgrade makes a real difference.
Most homes take 1–3 days depending on how many windows are being replaced. Homes that need significant trim or framing repairs around the openings may take a bit longer. Your home is sealed and secure at the end of each work day.
Yes — particularly in older Gloucester homes with single-pane or failed-seal windows. Modern low-E glass with argon fills cuts heat loss significantly. We also foam-insulate the window cavities during installation, which closes another common gap that most installers leave open.
Yes. Many homes downtown, in Magnolia, and around Eastern Point have architectural details worth preserving. We carry double-hung, casement, and specialty shapes in profiles that complement older homes while delivering modern energy performance. Andersen and Marvin both offer lines designed specifically for historic renovation.
Yes. D&G Exteriors LLC is fully licensed and insured in Massachusetts. We’re Google Guaranteed, BBB Accredited with an A+ rating, and carry all required certifications for window installation.
