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 composite deck building to complete replacements, we handle every deck need for Marblehead’s oceanfront estates and historic homes. 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.
Marblehead’s salt air and multi-directional coastal exposure cause wood to rot, splinter, and fail within 3–5 years. Pressure-treated lumber, cedar, and composite alternatives with wood cores all deteriorate rapidly in peninsula environments. Trex and TimberTech composite decking is engineered for salt air — it won’t rot, splinter, or degrade in coastal exposure. Over a 20-year lifespan, composite is the only choice that makes sense.
We’re a certified installer for Trex, TimberTech, and Azek composite decking. All three are premium composite lines engineered for coastal environments that won’t rot, warp, or splinter. We help Marblehead homeowners choose based on color, texture, budget, and use. All come with manufacturer warranties that we can activate as a certified installer.
Most composite deck projects in Marblehead range from $20,000 to $50,000+, depending on size, material choice, railing systems, stairs, and custom features like lighting or under-deck drainage. Oceanfront properties and multi-level decks with premium options run higher. We provide detailed estimates after an on-site consultation.
Most deck builds take 2–4 weeks from start to finish, depending on size, complexity, and permitting. Marblehead’s permitting process requires structural plans and inspections. We handle all coordination with the building department. Weather and material delivery timelines can affect scheduling in coastal areas — your project manager keeps you updated throughout.
Yes. The Town of Marblehead requires building permits for new deck construction and most major replacements. The permit process includes plan submission, structural review, and inspections at key stages. We handle the full permitting process — plan preparation, submission, and scheduling inspections — so you don’t have to navigate it yourself.
Many Old Town properties have compact backyards with setback requirements that limit how far the deck can extend. We design around these constraints — sometimes that means creative multi-level layouts, built-in seating, or vertical details that maximize usable space. We pull setback requirements and easements for your property before design starts.
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.
