Gloucester’s Cape Ann location means ocean exposure from three sides — wood decks rot within years here. Composite is the only material that makes sense for coastal outdoor living.

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.
From oceanfront composite builds to complete tear-down replacements, we handle every deck project on Cape Ann. Certified, licensed, and insured.

Understanding how you plan to use the space. Are you building for entertaining, a quiet sitting area, an outdoor kitchen, a hot tub, or creating usable space under the deck? The answer determines the layout, size, material choices, and structural requirements. We don’t start with a standard design — we start with a conversation about how your family actually lives outside.
Gloucester sits at the tip of Cape Ann with ocean on three sides. Salt air, fog, wind-driven moisture, and nor’easters cause wood — even pressure-treated and cedar — to rot, warp, and splinter within 3–5 years. Composite decking from Trex, TimberTech, and Azek is engineered for this environment. It won’t rot, splinter, or degrade. Over a 20-year lifespan, it’s the only material that holds up and makes financial sense.
We’re a certified installer for Trex, TimberTech, and Azek. All three are premium composite lines engineered for coastal environments. We help Gloucester homeowners choose based on color, texture, budget, and intended use. All come with manufacturer warranties that we activate as a certified installer — your investment is protected from day one.
Most composite deck projects in Gloucester range from $30,000 to $80,000+, depending on size, material choice, railing systems, stairs, and custom features like lighting or under-deck drainage. Oceanfront properties at Eastern Point or Bass Rocks with multi-level decks and premium options run higher. We provide detailed estimates after an on-site consultation.
Most builds take 2–4 weeks from start to finish, depending on size, complexity, and permitting. Gloucester’s coastal weather can affect scheduling — wind and fog days are real. Your project manager keeps you updated on timeline and adjusts for conditions. We handle all permit coordination with the City of Gloucester building department.
Yes. The City of Gloucester requires building permits for new deck construction and most major replacements. The process includes plan submission, structural review, and inspections at key stages. We handle everything — plan preparation, submission, and scheduling inspections — so you don’t have to navigate City Hall yourself.
Yes. Many Cape Ann properties sit on granite ledge or steep coastal terrain. We design around these conditions using engineered post foundations, helical piers where needed, and multi-level layouts that work with the natural grade rather than fighting it. Some of the best deck designs in Gloucester take advantage of elevation changes to create dramatic views and tiered outdoor living spaces.
We are Trex Certified Installer, TimberTech Pro Certified, Google Guaranteed, and BBB A+ rated. These credentials mean we meet strict licensing, insurance, and quality standards for composite deck installation. Manufacturer certifications ensure your deck is backed by the brand and installed to their specifications.
