Garage floor concrete in Arlington VA - a level slab that holds up to your car
Cracked, sinking or dusty garage floor? We pack a solid base and pour a new slab, finished on time so it stays flat.

What does a new concrete garage floor involve in Arlington?
Garage floor concrete in Arlington is a slab poured on packed ground inside your garage, then finished, jointed and cured into a hard, flat surface you can park on and work on for years.
Most calls start with a floor that's cracked, sinking, holding puddles or wearing to dust under the tires. The price turns on the garage's size, the slab's thickness, which for garages around Northern Virginia runs on the thicker end of home floors, and whether we break out and haul away an old slab first, since that adds demolition on top of the new pour. The schedule turns on curing, the stretch when fresh concrete gains strength, so you'll park somewhere else for a while, and your own figure comes in the written estimate. If the garage is dug into a slope that needs holding back, we also build concrete retaining walls.

Why homeowners trust Mainstay Arlington Concrete Construction for garage floors
I start with the slope and where water runs, so the floor falls toward the door and not toward the house. We dig out and pack the subgrade, the ground the slab sits on, so it carries the floor evenly. Nobody sees that base once it's poured, so if the budget's tight, I'd trim the finish before the base.
Timing matters on a garage floor, a lot like getting plates out on time, because finishing, cutting joints and curing at the wrong moment can leave cracks, high and low spots, puddles and a top that wears fast. Ask any contractor you're comparing how they time finishing and curing around the pour, and I'll walk you through ours.
Garage floor questions we hear
How much does a new concrete garage floor cost in Northern Virginia?
A reinforced concrete slab in Northern Virginia usually costs about $7 to $12 per square foot, and that's the going rate around here for the slab itself, not our quote. Your figure depends on the size and the prep your garage needs, and I put it in writing after seeing the space.
How long does a new concrete garage floor take before I can park on it?
Plan on about a week before you park on it or move heavy storage back in, though you can usually walk on it within 48 hours. Concrete keeps curing for about a month, so that first week is the safe wait, and it's a good time to park in the driveway or on the street.
Do I need a permit for a new garage floor in Arlington County?
Two Arlington County permits can come up on a garage floor job. The county requires a land disturbance and stormwater permit for work that disturbs 2,500 square feet of land or more, and a right-of-way permit when work blocks or limits a travel lane or curbside parking. If your job needs one, we handle the application with the office that covers your address, and the county's Building Permits line at 703-228-3800 answers questions on what's required.
Who licenses concrete contractors in Virginia?
Virginia's Board for Contractors licenses businesses that do construction, removal, repair or improvement work on property owned by others. Each license has a class, A, B or C, that sets how large a contract it allows, plus a specialty for the type of work, and Class C covers a single contract over $1,000 but under $30,000, so ask any contractor which class and specialty they hold.
Should I plan for an epoxy coating before pouring a new garage floor?
Yes, tell us before the pour, because water vapor rising through a slab can make moisture-sensitive coatings fail. That can show up as peeling, discoloration, loose spots you could trip on, and sometimes mold and musty odors, and knowing your plans up front changes how we prep the slab.
How do I keep a new concrete garage floor from cracking?
Ask for control joints, straight cuts that give the slab a planned place to crack, and find out before the pour where the crew will put them. It's also worth asking whether the mix has entrained air, tiny evenly spread bubbles that leave room to relieve the pressure when water in the concrete freezes.
