WHY D&G ・ BEVERLY'S CERTIFIED DECK BUILDER
Most deck builders frame it up and slap boards on top. We start by understanding how you’ll actually use the space — entertaining, cooking, lounging, hot tub — then design and build around that.

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.

Quality workmanship. No BS. Would hire D&G Exteriors again without hesitation.Posted on Zamer GambrellTrustindex 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.

OUR APPROACH ・ HOW WE BUILD DECKS
A deck is only as good as what’s underneath it. We engineer the structure first, then build the surface you’ll actually enjoy.
Building or upgrading a deck raises important questions. Here, we address some of the most common inquiries about our deck services to help you get started.
We specialize in composite decking from Trex, TimberTech, and Azek — low-maintenance materials that won’t warp, rot, splinter, or need annual staining. We also build with pressure-treated lumber and cedar for homeowners who prefer natural wood. For railings, we install composite, aluminum, and cable rail systems. As certified Trex and TimberTech installers, our work is backed by full manufacturer warranty coverage.
Most deck builds in Beverly take 2–4 weeks from start to finish depending on size, complexity, and permitting. Multi-level decks, custom features like built-in seating or outdoor kitchens, and elevated builds take longer. We handle design, permitting, and construction — you’ll get a detailed timeline before we start.
Yes. We handle board replacement, railing repairs, structural fixes, stair rebuilds, and full deck resurfacing. If your deck’s framing is still solid but the surface is worn out, we can replace just the decking and railings with composite without tearing down the whole structure. We’ll inspect what you have and tell you whether a repair, resurface, or full rebuild makes the most sense. We also provide other outdoor services like painting, roofing, and more to keep your exterior in great condition.
Understanding how you plan to use the space. Entertaining, grilling, hot tub, kids’ play area, quiet sitting area, usable space underneath — each one changes the design, materials, layout, and structural requirements. We start with a conversation about how you live and what you want, then design around that. Not the other way around.
A typical Trex or TimberTech composite deck runs $20,000–$45,000 depending on size, elevation, and features. Multi-level builds, cable railings, lighting, and under-deck drainage systems push the cost higher. Pressure-treated wood decks cost less upfront but need annual maintenance that adds up over time. We provide a detailed written estimate after visiting your property.
Composite doesn’t rot, warp, splinter, or fade — and it never needs staining or sealing. Pressure-treated wood needs refinishing every 1–2 years, and in Beverly’s climate it still cracks and deteriorates over time. Composite costs more upfront but eliminates recurring maintenance costs. Most homeowners break even within 5–7 years and get a better-looking deck for the life of it.
Yes. Deck projects in Beverly require building permits and inspections. We handle the full permitting process — drawings, applications, and coordination with the building department — so you don’t have to deal with it.
Manufacturer certifications for the materials they install — not just a contractor’s license. A Trex or TimberTech certification means the builder has been trained and vetted by the manufacturer, and your deck qualifies for full warranty coverage. Also look for proper structural engineering, verified reviews, and insurance. D&G Exteriors is Google Guaranteed with a 5.0-star rating across 150+ reviews.
