Composite decks built for Swampscott’s oceanfront lifestyle. Certified Trex and TimberTech installers with precision framing, hidden fasteners, and premium finish details. Google Guaranteed with 150+ five-star reviews.






Swampscott is one of the North Shore’s most desirable coastal towns, and the homes here reflect that — from the oceanfront properties along Puritan Road and Humphrey Street to the established neighborhoods off Paradise Road and Redington Street. But ocean proximity means constant exposure to salt air, moisture, and wind. Older pressure-treated decks along this stretch of coastline deteriorate fast — warped boards, corroded fasteners, and soft spots that make the whole structure feel unreliable. We build decks in Swampscott that match the quality of the homes they’re attached to and hold up against everything the ocean throws at them.

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.

Whether you’re replacing a worn-out deck on a raised foundation off Humphrey Street, adding outdoor living space to a home near Phillips Beach, or building a ground-level entertaining area in one of Swampscott’s inland neighborhoods, we manage the entire process. Design, permitting, teardown if needed, and a complete build with composite materials and the kind of detail work that belongs on a home in this town.

It depends on the size, material choice, elevation, and how complex the design is. Most Trex or TimberTech composite decks in the Swampscott area fall between $20,000 and $45,000 for a standard residential project. Larger builds, multi-level layouts, or features like built-in seating and cable railings will run higher. We put together a detailed proposal after visiting your property so you know exactly what you’re getting.
We start by understanding how you want to use the space. Are you looking for an area to entertain and host dinners? A quiet place to sit and enjoy the ocean air? Do you want an outdoor kitchen or a spot for a hot tub? Should the underside be usable — maybe as a dry storage area or a shaded patio below? Those details shape everything from the structural requirements to the layout and material choices, so that conversation always comes first.
That’s exactly why we recommend it here. Composite decking from Trex and TimberTech is engineered to resist moisture, salt, UV fading, and insect damage — all the things that destroy pressure-treated wood along the coast. It won’t warp, crack, or splinter, and it never needs staining or sealing. For a town like Swampscott where the ocean exposure is constant, composite is the clear choice.
Yes — deck projects in Swampscott typically require a building permit from the town. Properties close to the ocean or in certain zones may have additional requirements. We handle the full permitting process on every job, including any coordination needed with the building department, so nothing gets held up.
The ledger board — where the deck connects to your home’s framing — is the most critical waterproofing detail on any deck project. We install proper flashing behind the ledger, use stainless steel fasteners rated for coastal environments, and make sure water has a clear path to drain away from the connection. Most of the deck failures we see in Swampscott started right here, with a builder who skipped or shortcut the flashing.
Most deck projects take 1–3 weeks once construction starts, depending on the size and complexity. Permitting and material lead times can add a few weeks before that. We include a clear timeline in every proposal so you know what to expect from start to finish.
If you want to keep an unobstructed sightline — which a lot of Swampscott homeowners do — cable rail is the best option. It’s clean, modern, and doesn’t block your view. We also install composite railings from Trex and TimberTech and aluminum rail systems. The right choice depends on your budget, the style of your home, and how much you want to see through the railing. We’ll go over the options during design.
