the short answer

designed, permitted and built from the footings up

Most of the decks we build in Wellesley are composite, because composite boards do not rot, splinter or need staining, and they handle freeze-thaw cycles far better than wood. We design the layout with you, pull the building permit, set footings below the frost line, frame with pressure-treated lumber and finish with the decking and railing you choose. A typical deck takes one to two weeks to build once the permit is issued.

custom design, permits and construction

Design around how you use the space

We start with how you want to use the deck: dining, grilling, a hot tub, stairs down to the yard or a connection to a patio door. Then we size it, plan the stairs and railings and pick a board color and pattern that suits the house.

Permits handled for you

Building or replacing a deck in Wellesley requires a building permit and inspections. We prepare the plans, file the permit and schedule the footing, framing and final inspections so the deck is approved and safe. Depending on the town's requirements, some decks also need zoning approval, which can require a property survey at additional cost. We tell you during the estimate if yours does.

Built to code from the ground up

Footings go below the frost line so the deck does not heave in winter, the ledger is flashed and fastened to the house to keep water out of the wall, and framing, guardrails and stairs are built to Massachusetts building code.

decking materials we build with

Wood deck at dusk

Composite decking

We install Trex, TimberTech and Fiberon composite decking. Premium capped lines such as Trex Transcend and TimberTech's polymer-capped boards resist stains, fading and scratches and carry some of the longest warranties in the industry. Fiberon's slip-resistant texture is a practical choice for wet springs and icy mornings. See our composite decks page for every line we offer.

Composite deck with cable railings

Pressure-treated and cedar

Wood keeps the upfront cost down and gives a natural look. It needs regular cleaning and sealing to last, and we will explain the upkeep before you choose it.

Still deciding? Our guide to the best decking materials compares cost, maintenance and lifespan.

Deck Replacement

If your deck has soft boards, loose railings or a framing problem, we inspect it first. When the frame is sound, new decking and railings may be enough. When it is not, we take the deck down and rebuild it properly. We have rebuilt decks after storm damage too: a homeowner in nearby Ashland had a deck badly damaged by a fallen tree, and our team set an accelerated timeline so the rebuild lined up with the rest of their repairs.

Railings, Stairs and Finishing Details

We install composite, aluminum and wood railing systems, with matching post caps, stair treads and optional deck lighting. Railings are built to code height and spacing, and we coordinate color between the railing and the decking so the deck reads as one design.

frequently asked questions

Do I need a permit to build a deck in Massachusetts?

Yes. Most towns, including Wellesley, require a building permit and inspections for a new or replacement deck. Depending on the town's requirements, a deck may also need zoning approval, which can require a property survey at additional cost. We handle the permit for you.

How long does it take to build a deck?

Most decks take one to two weeks of construction, depending on size and complexity. Permit review comes before that, and we include it in the schedule we give you.

Is composite or wood better in New England?

Composite needs far less maintenance and holds up better to freeze-thaw cycles. Wood costs less upfront and looks natural but needs regular sealing. Most Wellesley homeowners choose composite.

How do I choose a deck contractor?

Ask for a registered Massachusetts contractor with insurance, written warranties, photos of finished decks and a clear plan for permits. We provide all of it with every estimate.

When is the best time to build a deck?

Decks can be built for most of the year. Planning ahead gives time for design and permit review, so the deck is ready when you want to use it.
