Window replacement built for Gloucester’s coastal conditions. Proper weatherproofing, rot-proof PVC trim, and energy-efficient glass packages chosen for your home’s exposure. Google Guaranteed with 150+ five-star reviews.






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.

Posted on Curtis MatthewsTrustindex verifies that the original source of the review is Google. Our house in Danvers needed new siding and trim, and this was not an easy project. There were surprises once the old siding came off, but John walked us through everything calmly and professionally. The final result looks incredible and feels built to last.Posted on Joshua DixTrustindex verifies that the original source of the review is Google. Very professional operation. Clear contract, good communication, and high-quality work. Our new roof looks great and the flashing details are far better than what we had before.Posted on Imani YussifTrustindex verifies that the original source of the review is Google. We’re in Marblehead, close to the water, and needed exterior work that could actually stand up to the elements. D&G Exteriors replaced our roof and trim, and the difference in quality compared to previous work on the house is obvious.Posted on Miguel RojasTrustindex verifies that the original source of the review is Google.

We live right on the ocean in Gloucester, and the weather absolutely beats up our house — constant wind, salt spray, storms rolling in off the water. After years of patching things, we finally decided to hire D&G Exteriors for a full roof replacement and some badly needed trim repairs. I’m so glad we did. Working on a house this close to the shoreline is no simple job. The crew had to deal with strong winds almost every day, and once they pulled the old shingles off, we found sections of the roof deck that were softened from years of salt exposure. John didn’t overreact or try to turn it into a huge problem — he showed us the damage, explained what needed to be replaced, and kept everything straightforward and fair. Despite the tough conditions, the team worked cleanly and efficiently. You could tell they were used to handling challenging environments. They installed new CertainTeed shingles, repaired the compromised areas, and replaced all the rotten fascia and trim with PVC so we won’t have to worry about it again. The house looks incredible now — sharper lines, cleaner edges, and a roof that finally feels like it can handle a real coastal storm. The best part was how professional the whole process was. They kept the site tidy even with the wind constantly blowing debris around, communicated every day, and never left us guessing about what was happening next. If you live anywhere near the water and need roofing or exterior work, D&G Exteriors is absolutely the company you want. Five stars, without hesitation.Posted on brian haskinsTrustindex verifies that the original source of the review is Google. We’re in Ipswich, and hired D&G Exteriors to replace our roof and correct a long-standing issue around a valley that had leaked during heavy rain for years. Previous repairs never fully solved it. John identified the problem immediately, reworked the flashing detail, and rebuilt that section properly instead of just patching it again. Since the replacement, we’ve been through multiple hard storms with zero issues. The roof looks great, but more importantly, the problem is finally gone. Very happy with the work and the attention to detail.
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.
