Deck Building Services We Offer in Boston
We do decks. New ones. Old ones. The ones your uncle fixed with nails and hope.
We can only offer a custom deck design Boston houses really deserve. We sketch it first, then turn it into something that won’t collapse when your dog jumps on it. That’s what only a few deck replacement Boston companies are capable of.
We remove rot, fix the boards, replace what is damaged or worn beyond repair. We’ve handled enough deck repair Boston jobs to know everything about doing it right.
We’ve completed lots of rooftop deck Boston jobs as well. We’ve built them on triple-deckers with 200-year-old joists that groan like ghosts. After reinforcing them, of course.

Decking Materials We Work With
Trex is the first option.. We’re TrexPRO installers. After 12 winters in Boston, cheap pressure-treated wood looks like a zombie. Trex doesn’t rot. Doesn’t splinter. Doesn’t need sealing. It simply continues to exist. Pressure-treated wood can be really fine if the brand is right.
IPE hardwood is the second option. It’s gorgeous. It’s expensive. It looks like it belongs in a Bali villa. Though it’s vital to keep it from cracking when the freeze-thaw hits. We frame with pressure-treated lumber unless you’re ready to afford cedar. It always costs extra but it’s worth it.
Why Boston Decks Need to Be Built Right the First Time
Boston doesn’t just have seasons. It has moods. One day it’s spring. The next day it snows. Then it rains. Then salt air from the Atlantic crawls in. Then more snow.
If a ledger board is flashed the wrong way it turns to mush. Bad footings sink like a sinking ship. Unpermitted deck? Your next buyer will give you a look of disdain. Or the city will force you to tear it down.
We don’t cut corners. We go below the frost line. We use galvanized hardware. We get all the required permits. We know the code. We’ve been in basements across Massachusetts. We’ve seen more than one DIY deck that became a lawsuit. We don’t do that.

Frequently Asked Questions — Deck Builders in Boston, MA
Do I need a permit to build a deck in Boston, MA?
Yes. We've seen decks get demolished because someone thought they didn't need no permits.
How long does it take to build a deck in Boston?
Depends. Around five days for a 12x16 one. Rooftop deck on a brownstone? Two weeks. The most time-consuming process is getting the permit — four to six weeks. That's why we start the paperwork before you say yes.
What is the best decking material for New England weather?
Trex. Honestly. No maintenance. It doesn't warp. It doesn't fade. Wood is also a decent option but it requires sanding. IPE? Only if you want to pay $15K for a deck that looks like it belongs in a magazine. We've done all three. Trex wins.
How much does a new deck cost in Boston, MA?
$8K for a basic wood deck. $15K for Trex. $25K+ if you want lighting, stairs, a built-in planter, or a pergola.
Can you build a rooftop deck on a Boston triple-decker or brownstone?
We've done more than a hundred of them. We engineer them. We reinforce the structure. We get the permit. We've had inspectors say they've never seen this done right. We take that as a compliment.
Do you build decks for Boston's smaller urban yards?
Yes. We build and replace decks across Boston — from compact yards in South Boston and Charlestown to larger properties in West Roxbury and Newton.
