Repair, resurface or replace

Which one your deck needs depends on the frame, not the boards. Worn decking can sit on a frame with years left in it, and a deck that looks fine from the yard can be soft where it meets the house. We check the structure first, then tell you which of these it needs.

Repair

The frame is solid and only a few parts have failed, like a handful of soft boards, a loose rail or one rotted stair. We replace those and leave the rest.

Deck repair

Resurface

The frame is good but the surface isn't. We keep the framing and replace the boards, railings and stair treads, as long as the joists are close enough together for the new boards. Most composite decking is rated for joists 16 inches apart.

Deck resurfacing

Replace

The frame is the problem: rot at the ledger where the deck meets the house, joists that have gone soft, or footings that have heaved and pulled the deck out of level. Everything comes out, and the deck is rebuilt from the footings up.

What a deck replacement includes

A replacement covers every part of the deck, from the footings to the trim.

Tear-out and haul-away

The old decking, railings, stairs and framing come down, and the debris leaves with us.

Footings below the frost line

48 inches deep in Massachusetts and 42 in Connecticut. An existing footing stays only if it's that deep and still sound.

Pressure-treated framing

New posts, beams and joists, with the ledger bolted to the house and flashed so water can't collect behind it.

Composite or wood decking

Most of our replacements are composite from Trex, Azek, Fiberon or Deckorators. Pressure-treated and cedar boards are there if you'd rather have wood.

Compare decking materials

Railings and stairs

White vinyl railings with white or black balusters, and new stairs built to today's code.

PVC trim, post wraps and lattice

PVC fascia and sleeves over the posts and beams so nothing you can see needs painting, and lattice to close in the space underneath.

Can the new deck be bigger than the old one?

Yes, and replacement is the easiest time to do it. The old deck is coming down anyway and the new one needs its own permit, so adding a few feet of depth, a wider landing or stairs that land somewhere else is part of the same job rather than a second project. The usual limit is your town's zoning setback, which fixes how close a deck can come to the property line. We measure the new footprint against your lot at the estimate, and the layout you approve is the one that goes on the permit application.

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.

Excellent experience from start to finish! The team was professional, on time, and did an amazing job building our deck. The craftsmanship is top-notch, and everything turned out even better than we expected. I highly recommend them to anyone looking for quality work and great customer service!

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 deck replacement

Sometimes. A footing can stay if it reaches below the frost line, 48 inches in Massachusetts and 42 in Connecticut, and the concrete is still sound. Older footings set shallower than that get replaced. We check depth and condition at the estimate, and the quote shows which ones stay.

Yes. In most Massachusetts and Connecticut towns, replacing a deck takes the same building permit as building a new one. We file it with your town's building department, and the inspector typically checks the footings before concrete is poured and the finished deck at the end.

It depends on the size of the deck, the materials and your town, so the timeline is written into your quote alongside the scope. The permit is usually the longest wait: some Massachusetts and Connecticut building departments take a few weeks to issue one, and work can't start until it's in hand. Once it is, one crew stays on your deck from tear-out to the final walkthrough.

Yes, as long as the frame they're attached to is sound. New stairs and white vinyl railings are a smaller job than a full replacement, and we'll check the framing at the estimate. If it turns out to be failing, you'll hear that before anything is replaced.

It comes apart during the tear-out and leaves with us, so there's no dumpster to rent and no disposal to arrange on your end.

Yes, through Hearth. You can check your options on our financing page before the estimate or once you have the quote.

We replace decks across the South Shore and MetroWest from our Braintree and Wellesley offices, and across central Connecticut from Middletown. If you're not sure your town is covered, give us a call and ask.
