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.

Sustainable Decks did a great job replacing our rotting old deck with a bigger, beautiful Trex deck. The guys who did the work did a great job, and on schedule. Ben was great to work with on coordinating everything and working with us to design an improved layout.

We recently had our deck rebuilt and couldn’t be happier with the results. The team was professional, punctual, and paid attention to every detail from start to finish. The quality of the workmanship is outstanding, and the finished deck looks absolutely amazing. They kept the work area clean, communicated clearly throughout the project, and completed everything on time. I highly recommend this decking company to anyone looking for top-quality work and excellent customer service. Five stars all the way!

Amazing work. Ben's been great to work with on our new deck and it turned out better than my wife and I hoped. We can't wait to move into our new space and start enjoying a bug free outdoor space! If you're thinking about building a screened in porch these guys are great!

We had Sustainable Decks replace our old dilapidated deck and add an extension so it encompassed the entire back of our house. We could not be more IMPRESSED with their work. Ben was hands on from the initial estimate to the completion and walk through. Nick and Chucky were the guys that did all the work and it looks amazing. Also we thought their pricing was incredible. We had several estimates and they came through with the best price and the craftsmanship is awesome. I will be including before and after photos. If you want to get a deck replacement or add a new one THESE ARE THE GUYS TO CALL. Thanks Ben and crew for taking such good care of us and our property. They finished in the time frame promised and their attention to detail is awesome. We will definitely be using them to put a farmers porch on the front of our house next year. You will not be disappointed when you have these guys do work for you.

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.
