Custom composite decks for Somerville homes — Trex and TimberTech certified installer. Designs built for tight urban lots, multi-family buildings, and rooftop applications where every square foot of outdoor space counts. Google Guaranteed. 150+ five-star reviews.






Outdoor space is scarce in Somerville. At 4.2 square miles with 81,000 residents, the city is the densest in New England — and backyards are either tiny or nonexistent. A well-designed deck turns a narrow rear yard, an unused flat roof section, or an awkward side space into the outdoor room your property doesn’t otherwise have.

Posted on Bradford JonesTrustindex verifies that the original source of the review is Google. We had been in our home a long time and exterior was due for serious updates. Roof was from the early 90s, siding was peeling in layers, and the windows were old vinyl with seal failure and had no insulation. We kept putting it off until a neighbor recommended John. He spent over an hour walking the property with us on the first visit, pointing out things we hadn't even noticed, including a section where moisture had been getting behind the siding for years. He didn’t pressure us, just a clear explanation of what was going on and what it would take to fix it right. We ended up doing everything. Full roof, new siding, all new windows, and complete trim. The crew showed up early, kept the property clean (and cleaned up after), and communicated well throughout. When they found more damage than expected behind one wall, John called same day with pictures and options before moving forward. The transparency was both refreshing and important. It's been about a year and a half and everything still looks and performs exactly as it should. Heating costs dropped noticeably and was especially apparent this year. We live on a main street and the noise in our front bedrooms is gone. The house legitimately looks like a completely different property. If you're in the north shore area thinking about exterior work, get a quote and talk to John. You'll see the difference.Posted on Roman CooperTrustindex verifies that the original source of the review is Google. We have a big old farmhouse out in Boxford with a roof that probably should've been replaced five years ago. Finally pulled the trigger and called D&G Exteriors. John came out, looked everything over, and gave us a quote that was fair and detailed. Crew did the whole tear off and install in three days. No complaints at all.Posted on Parker SimmonsTrustindex verifies that the original source of the review is Google. I’m so impressed with the service I received.

Every deck starts with one question: how do you want to use this space? In Somerville, the answer matters more than most places because the space is limited and the design has to be smart.

Understanding how you plan to use the space. In Somerville, outdoor space is at a premium, so the answer shapes everything — entertaining, a quiet retreat, container gardening, a grilling station, a play area. The layout, size, materials, and structural requirements all flow from how you’ll actually live on the deck.
Most composite deck projects range from $25,000 to $75,000+ depending on size, materials, railing systems, and features. Somerville’s urban conditions — elevated builds, multi-family attachment points, rooftop applications — can add structural complexity that pushes toward the higher end. Detailed estimate after on-site consultation.
Trex and TimberTech/Azek. Both are premium composites that won’t rot, warp, or splinter. We help you choose based on color, texture, budget, and use. As a certified installer for both brands, we activate full manufacturer warranties.
In many cases, yes — but it depends on the building’s structural capacity and local zoning. Rooftop decks require structural engineering review, proper waterproofing of the roof membrane below, railing systems that meet code, and permitting. We assess feasibility before committing to a design.
Yes. Somerville requires building permits for new decks and most major replacements. The city’s Inspectional Services department reviews structural plans and conducts inspections at key stages. We handle all of it — plan preparation, submission, and inspection coordination.
Yes — and that’s the norm here. Zero lot lines, narrow side yards, and compact rear spaces are standard Somerville conditions. We design around the constraints with creative layouts, multi-level designs, and built-in features that maximize every square foot without violating setback requirements.
Pressure-treated is cheaper upfront but needs annual staining, sealing, and maintenance. It warps, splinters, and degrades in Middlesex County weather — and on a Somerville deck where neighbors are close by, a deteriorating deck is hard to ignore. Composite costs more initially but requires zero maintenance, won’t rot, and holds its appearance for decades.
Yes. If your existing deck is failing — rotted framing, wobbly railings, soft spots — we tear it down, inspect the ledger connection and building attachment, and rebuild to current code. Many older Somerville decks were built with substandard framing or before current ledger flashing requirements existed.
