Garage floor concrete in Stamford CT - the right fix for a cracked slab

Cracks, chipping or a slab that's sunk by the door? We'll tell you whether it needs resurfacing or a new pour, and do it right.

A smooth, reflective concrete floor with control joints fills an unfinished room lined with pale spray-foam insulation.

Should you resurface your garage floor or replace it?

At Caliber Stamford Concrete, garage floor concrete in Stamford, CT, is one of two jobs: resurfacing the top of a slab that's still sound, or tearing out a failed slab and pouring a new floor. Which one you need decides the cost and how long you'll be parking in the driveway.

Most calls start with a crack across the middle, a chipped patch where the tires sit, or a floor that's sunk by the door so water pools. Sometimes only the top layer is wearing out, and sometimes the slab underneath has moved. Those are very different fixes, so I check which one it is before anybody talks price.

The price mostly depends on the size of the floor, whether the old slab has to come out, and how much work the base needs once we can see it. The schedule turns on the same choice, because a new slab has to cure, which means waiting while it hardens enough to take a car, and it also depends on the weather and what the city wants. We're licensed and fully insured, and your written estimate spells out the prep, the mix and what's included, so you're not guessing.

  • Resurfacing puts a new top layer on a sound slab after the old surface is prepped.
  • Replacement means breaking out the old slab, hauling the debris away and pouring a new floor.
  • Oil stains, cracks and chipping usually decide how much prep the surface needs before anything new goes on.

What happens after you call about your garage floor?

Here's how a garage floor job runs with us, from the first call to the day you park on it. I'm the one who comes out, and my crew is the one who pours.

  1. Call or send the form

    Call (475) 333-3026 or send the form and tell us what the floor is doing. Photos of each crack help me come prepared, and if you've laid a straightedge across one, tell me what you saw.

  2. I walk and measure the floor

    I come out myself to look at the cracks, measure and ask what you need the floor to do, whether that's parking two cars or holding up a workbench. Then you get a written estimate that spells out the prep, the mix and what's included.

  3. We check with the city

    Once you say go, we check with the city's building office, and I set a pour date that makes sense for the weather and the cure. If the office hasn't given us an answer yet, we tell you that too.

  4. My crew pours, I check

    My crew does the work, and I'm on site for the steps that count most: the base, the pour and cutting the joints. When we're done, we tell you when you can walk on the floor and when the car can go back in.

How we handle garage floor concrete

First I figure out whether the surface failed or the slab itself did, because that decides between resurfacing and replacing. If the slab has moved, I'll tell you straight that a patch kit won't fix it. For a resurface, we clean and grind the old surface so the new layer has something to grab, fill what needs filling and put the new top down. For a replacement, we break out the old slab and haul it off. Then we dig out and pack the subgrade, the ground the slab sits on, and set the slope so water runs out the door instead of toward the house. We set rebar, steel bars that hold the slab together if it does crack, and we pour early in the day, because midday heat leaves a weak, dusty top. Then we finish the surface and cut control joints, shallow grooves that give the slab a place to crack where we chose and not where it feels like. When budgets get tight, people want to cut the base, since nobody sees it on day one. I'd cut the fancy finish first, because a nice looking slab on a bad base is just an expensive crack waiting to happen.

Most garage floors are a job on their own, but a couple of others sometimes come along with one. If you want more than plain gray, decorative concrete can add color or a pattern to the finish. Where the yard sits higher than the garage, concrete retaining walls hold the soil back so the new floor isn't fighting the hill.

  • Resurfacing the top layer

    This suits a slab that's still flat and solid but worn on top, with chipping, pitting or stains. It costs less and you're back in the garage sooner, but it won't help a slab that has moved.

  • Tearing out and pouring new

    This suits a slab that's sunk, heaved or cracked through with one side higher than the other. It takes longer and costs more, but you get a new base under it, and the base is what decides how long the floor lasts.

  • Broom finish or smooth finish

    A broom finish is a light dragged texture that gives tires and boots some grip when the floor is wet. A smooth troweled finish is easier to sweep and is what most coatings want, so pick by how you use the garage.

Questions about garage floor concrete in Stamford

These are the questions people in Stamford ask most before they decide what to do with a tired garage floor. If yours isn't here, ask me when I come out.

Should I resurface or replace my garage floor?

Resurface if only the top layer has failed, and replace if the slab itself has failed. Resurfacing the whole floor is usually the right call only when the damage is shallow and spread across most of it. When the slab is broken or has moved, replacement is often the only real fix.

How do I tell if my garage floor slab has moved?

Lay a straightedge across each crack. A level or any straight board will do, and if one side of the crack sits higher than the other, the slab has moved. At that point you're looking at lifting the slab or replacing it, not a repair kit from the hardware store.

How much does a new garage floor cost in Stamford, CT?

Across the US, replacing a garage floor, from tearing out the old slab to pouring the new one, usually runs about $10 to $16 per square foot. That's the market's range, not our quote. Your floor's size, base and access all move it, so the written estimate is where you get your own number.

How long does garage floor replacement take compared to resurfacing?

Resurfacing can often be finished in days, while replacement adds curing time that can stretch into weeks. That matters if you plan to coat the floor, because the coating has to wait for the new slab. Water vapor coming up through concrete can also make a moisture-sensitive coating come loose later, and a loose coating is a tripping hazard.

When can I park on a new garage floor?

You can usually walk on a new garage floor after 24 to 48 hours, but the car should stay off it for 7 days. Park in the driveway for the week, because a cracked new slab is a lot more annoying than a short walk.

Can concrete be poured in a Stamford winter?

Yes, as long as the new slab is kept from freezing, because fresh concrete freezes below about 25°F and frozen concrete can lose more than half its strength. Ask any crew, us included, how they'll protect the slab for about two days after the pour. Any fuel-burning heater in a closed garage should be vented, both for safety and so the new surface doesn't turn dusty. An Ohio concrete trade group also advises keeping deicing salt off new concrete for its first year, especially if it went in after September, and using sand or kitty litter for grip instead.

Garage floor concrete in Stamford and nearby cities

The City of Stamford issues permits for replacing and demolishing work, but its list doesn't name garage floors, so before a tear-out we ask the city's building office what your job needs and handle any application with you. We see plenty of older garages here with floors that have sunk at the door, and we do the same work in Norwalk, Greenwich and the other cities around Stamford, in Connecticut and across the line in Westchester.
