What does it take to put in a new concrete floor in Boston?

Concrete floor installation in Boston, MA means pouring a new slab on a packed base, laid right on a vapor retarder, a sheet that holds back moisture coming up from the ground, so the floor covering you put on top isn't fighting damp from below.

Most people call us when an old basement floor is cracked, sinking or damp, or when they're adding a room that needs a slab under it. The price moves with the floor's size, whether an old slab has to be broken out and carried up the stairs, how much digging and packing the base needs, and whether we're pouring in the cold, which takes extra protection. The schedule turns on any permit, the weather and curing, the wait while the slab hardens before anyone loads it. If the budget's tight, I'd keep the money in the base and save on the finish, because you can redo a surface but you can't fix what's under it without tearing it out. The written quote I give you shows what goes under the concrete as well as what you'll see, so you get your own figure.

Concrete floors, from the dirt up

I decide what a floor needs by looking at what's under the old one and asking what's failed before, the same thinking we bring to concrete steps and concrete pool decks.

  • Dig out and pack the base

    We dig out and pack the subgrade, what the slab sits on, because a base that's only raked flat settles and cracks the floor.

  • Lay the vapor sheet intact

    We lay the vapor sheet right under the slab and patch every tear, since even small holes let moisture through to your flooring.

  • Pour and trowel smooth

    We plan the pour around the weather and trowel the floor smooth, because a slab that dries too fast gets a weak, dusty top.

  • Cut joints and let it cure

    We cut control joints, grooves that steer cracking to lines we choose, on time, then keep traffic off while the slab cures.

Why homeowners hire Ironset Boston Concrete Construction

I spent years patching steps, walks and slabs on rental buildings around Boston and kept asking why they broke down. I started this business in 2023 to build concrete that doesn't need that patching, and we're best known for awkward jobs like a slab that keeps cracking.

  • I come out and quote it myself

    I look at your floor and write the estimate myself, then work alongside our crew while they form, pour and finish, so the person who quoted it is there on pour day.

  • Licensed and fully insured

    We're licensed and fully insured, and we'll show you that before any work starts, so you're not guessing about who's covered while a crew is working in your house.

  • Satisfaction guaranteed, hidden work first

    Satisfaction guaranteed. We put our care into the parts you won't see once the floor is down, the base, the drainage and the prep, because those decide how it holds up.

What happens when you call about a concrete floor in Boston?

We plan the floor around how you'll use the room and what you'll lay on top. Once the quote's agreed, our crew forms, pours and finishes it, and I walk the floor with you at the end.

    Call (617) 226-2081 or fill in the form with the room, the rough size of the floor and what's there now.

  2. I look at the floor

    I come out, look over the old floor and ask what's gone wrong there before, since old cracks and damp spots usually have a cause.

  3. You get a written quote

    Your quote shows what goes under the concrete, not just the floor you'll see, and if a permit's needed, we line it up before we schedule the pour.

Questions about concrete floors in Boston

How much does a new concrete floor cost in Boston?

A concrete slab in Boston usually costs about $4.50 to $8.50 per square foot, and that's the going rate in the area, not our price. Where your floor lands depends on breaking out the old slab, how hard the room is to reach, how much base work it needs and whether it's poured in the cold. Your written quote gives you the figure for your own floor.

Will my new concrete floor crack?

A few small random cracks should be expected in any new concrete floor, even when the joints are cut close enough together. That's normal for a new slab, so we tell you before the pour and you can pick a floor covering that handles it.

How long does a new concrete floor need protecting when it's cold out?

A Michigan concrete association's guide advises keeping fresh concrete at 50°F or above for at least 3 days, covered right away with insulated blankets, straw or heated enclosures. Cold weather counts once the air falls, or is expected to fall, to 40°F while the concrete still needs protecting, so a winter pour in Boston needs that plan settled before we set a date.

How do I know if a contractor can legally pour my floor in Massachusetts?

On most owner-occupied 1- to 4-family homes, the state requires a licensed construction supervisor or a registered design professional to oversee the work. The contractor also has to be registered as a home improvement contractor, which is a separate credential from the supervisor license and can't stand in for it, so ask about both.

Can I pour my own concrete floor in Boston?

Only if you own and live in a 1 to 2 family home, since that's when the city lets homeowners do the work themselves. If you own a unit in a building with 3 or more homes, you have to hire a licensed contractor.

Can work on my floor start before the Boston permit is issued?

No, work should wait until the permit is issued, because the city may otherwise charge double the permit cost or issue a building code violation. When a job needs a permit, we have it in hand before the crew shows up.

Concrete floor installation inside Boston city limits

Inside the city, Boston's Inspectional Services issues the permits, Long-Form for work that changes a home's structure or use and Short-Form for minor work that doesn't. The city doesn't say which one a new floor slab falls under, so we check with the building office about your job instead of guessing, and we help line the permit up before work starts. If your house is in the city's Flood Hazard District, bring it up early, because homes there can't have a basement whose floor is below grade on all sides, and that can change whether a basement floor is the right plan at all.

We're based in Boston and work across the cities around it, and we see the same older houses on jobs in Somerville and Cambridge, with tight basement stairs and old floors poured with no sheet under them. So we plan how the old concrete comes out and the new concrete gets in before pour day.
