Deck Builder in Wellesley, MA
Decks, porches, patios and siding from our office on Worcester Street, for Wellesley houses from new builds to a century old. We also work across Newton, Needham, Natick, Weston and Dover.
In Wellesley Hills and Cliff Estates, a new deck often goes onto a house that's stood for a century or more. We open up the framing and check what the deck will hang from before anything is attached, then match the railing and trim to the house so the new work looks like it belongs. Sustainable Decks builds across Wellesley from our office on Worcester Street, with 1000+ projects completed and a 5.0 rating on Google. One crew stays on your job from the first footing to the last board.

Decks on century-old houses
On a house that old, what changes most is the way the deck attaches. A deck usually hangs off the house on a ledger board, and on framing from the early 1900s there's no telling what's behind the siding until it's opened up, so that's the first thing we do. When the framing is sound, the ledger goes on with flashing behind it to keep water from sitting against the old wood. When it isn't, the deck stands on its own posts instead and never leans on the house at all. Getting that right frees the visible part to follow the house. The railing, post caps and trim are chosen to suit it, which is how a composite deck ends up looking at home on a house a hundred years older than its boards.

Do you need a permit for a deck in Wellesley?
In most cases, yes. A deck or porch attached to the house, or more than 30 inches off the ground, needs a permit and inspections from the Wellesley Building Department, while a patio laid at grade usually doesn't. Footings go down 48 inches, the Massachusetts minimum, and the framing is sized for the 40 pounds per square foot of ground snow the state sets for Wellesley. Lots near Fuller Brook, Morses Pond, Lake Waban or the Charles add a step, because anything within 100 feet of a wetland or 200 feet of a river also goes through the town's wetlands review. We confirm all of it for your address before the quote is final, and we file the permit ourselves.

Questions people ask about building in Wellesley
At 888 Worcester Street #130, on Route 9 in Wellesley. It's our MetroWest office, and the jobs we run across Wellesley, Newton, Needham, Natick and the towns around them all start from there.
A standard single-level deck usually takes one to two weeks once the material arrives, with weather and permit timing on top of that. Footings can go in once the ground is workable in spring, and the season runs roughly April through November. Planning over the winter means the permit can be in hand when it opens.
Yes. We build covered, screened-in and farmers porches as well as decks, along with patios and siding. A porch follows the same rule a deck does here, with the roofline, columns and trim taken from the house it's attached to so it reads as part of the original.
Yes. Financing is available on larger projects, so the scope of the job can follow what the house needs rather than what fits this month's budget.
