Deck Builder on the South Shore
Composite and pressure-treated decks, porches, stairs, and railings — built for years of outdoor living, with the structure underneath done right.
What deck building covers — and who it's for.
Deck building is the whole outdoor structure — framing and footings, decking, stairs, and railings — in composite or pressure-treated wood. It's for homeowners who want usable outdoor living space that's safe, level, and built to handle New England seasons year after year.
Deck services we offer.
Composite decking
Low-maintenance composite boards that resist fading, staining, and rot.
Pressure-treated decks
Classic, cost-effective wood decks built to last and ready to stain.
Porches & stairs
Porch systems, landings, and stairs integrated cleanly with the home.
Railings
Wood, composite, and metal railing systems that are safe and code-compliant.
Why homeowners pick us for decks.
A deck lives or dies on what's underneath it. We get the footings, framing, and ledger connection right so your deck stays solid and level for decades — then finish it cleanly with decking, stairs, and railings you'll be glad to use.
We've built decks and porches of every size across the South Shore over 30+ years, from simple platforms to elevated decks with full stair and railing systems.
Solid structure
Footings and framing built to code and to last, not just to look finished.
Material choice
Composite or pressure-treated, matched to your budget and upkeep preference.
Clean finish
Stairs, railings, and skirting detailed so the whole deck ties together.
How a deck build goes.
We handle the design, permitting, and build, and keep you updated throughout. The structure goes in first, then the finish work you'll see and use.
1. Design & permit
We plan the layout, choose materials, and pull the permits the job needs.
2. Footings & frame
Footings, posts, beams, and framing go in level and to code.
3. Deck, stairs & rails
Decking, stairs, and railings are installed and finished, then we clean up the site.

What customers say about our work.
We had all of the exterior trim around our house replaced, and I couldn't be happier with the work Chris did. The quality and attention to detail really stood out, and it was clear from day one that he genuinely cared about doing the job right — making sure the end result was something he'd be proud of, as if it were his own house. Beyond the great craftsmanship, I truly enjoyed working with Chris along the way. He was easy to talk to, communicative throughout the project, and clearly invested in the outcome. We loved the finished product so much that we've already scheduled him for more work, and I wouldn't hesitate to recommend him to anyone looking for a contractor who truly cares about both the process and the result.
Kyle Jennings South Shore, MAI've used CB Builders many times, for many projects. They're excellent at roofing and siding. Every time, they walk me through the specific challenges of the project and offer solutions to all of them. When I bring them onto a project, I'm confident the job will be done right. Will definitely use them again.
Dominic Watkins South Shore, MAWhether you need a roofer, new siding on your house, new windows, or even a deck — no need to look any further. They are very affordable, reliable, and very informative. I give them 5 stars and would recommend them to everyone.

Deck questions, answered.
How much does a new deck cost?
Most decks on the South Shore run from roughly $8,000 to $30,000+, depending on size, height, material, and features like stairs and railings. Composite costs more up front than pressure-treated but needs far less upkeep. Your estimate is free.
Should I choose composite or pressure-treated?
Composite is low-maintenance and holds its look for years without staining or sealing. Pressure-treated wood costs less up front and can be stained to taste. We build both and will help you weigh cost versus upkeep.
How long does it take to build a deck?
Most decks take about one to two weeks depending on size, height, and complexity, plus any permitting time. We'll give you a clear schedule before we start.
Do I need a permit for a deck?
Most decks do require a permit in Massachusetts. We handle the permitting and build to code so it passes inspection and is safe for the long haul.
What about the structure underneath?
The framing, footings, and ledger connection are what keep a deck safe and level for decades. We do that part right — it's the work you don't see that matters most.
