Should I resurface my garage floor or pour a new slab?

Garage floor concrete work in Union City usually means one of two jobs. One is a thin new surface over a floor that's worn but still solid. The other is a new reinforced slab strong enough to carry your cars. Professional Union City Concrete does both, and we'll tell you plainly which one your floor needs.

Most calls start with a floor that's chipping, stained, cracked across the middle or sinking in one corner, or with a remodel that needs a fresh slab. The price moves with the size of the garage, whether it gets a new surface or a full new slab, how much steel goes into it and how much work the ground needs before we pour. The schedule turns on that same choice, because a new slab has to cure, the waiting time that lets concrete gain strength, before you can put your car back in. I come out, look at the floor and write an estimate that shows what's included, so you get your own number instead of a guess.

How we handle garage floor concrete

I start by checking whether your floor just needs a new surface or a full new slab, and I note any paint, sealer or settled spots, because those decide which way the job can go. If it's a new slab, our crew compacts the subgrade, the ground the slab sits on, carefully before we pour, since a base that's only raked level settles with the dirt and pulls the floor down with it. Garage slabs carry real weight, so we reinforce them with rebar or wire mesh, steel that holds the concrete together if it cracks. We set the forms so water runs toward the garage door and away from the house, and we pour early in the day so the heat doesn't dry the top too fast and leave it weak and dusty later. Once the floor is finished, we cut control joints on time. These are shallow grooves that give the concrete a place to crack where we chose, instead of across the middle of your floor.

Some owners want more than a plain gray floor, and color or texture is part of our decorative concrete work. If the budget gets tight, though, I'd put the money into the base before the finish, because the ground under the slab is hidden the day we pour and it's the one part you can't fix later. When the driveway slopes toward the garage, we also build concrete retaining walls to hold the soil back beside it.

Garage slabs, permits and site work in Union City

The City of Union City asks for the appropriate permits when you build, remodel or improve a home. It also asks for a grading permit on any project that grades, digs out, fills or clears soil. The list doesn't name garage floors on their own, so I check with the city before we start. When your job needs a permit, we take care of the application and inspections and keep you informed along the way.

Standard floor slabs in Bay Area homes run four to six inches thick, and garage slabs sit at the thicker end because they hold vehicles. Many of the garages we see here have floors that have worn down, picked up oil stains or settled in a corner over the years. We see the same floors on jobs in Fremont and Hayward.

How garage floor work goes

  1. Call and set a visit

    When you call or send the form, we set a time for me to come out, look at the garage and listen to what you have in mind. If you can, move enough off the floor that I can see the cracks and low spots.

  2. Go over the written estimate

    My estimate lists what's included and what isn't, from the slab thickness to the reinforcement and joints, so you can compare it line for line with other bids. We talk through resurfacing and a new slab before you decide anything.

  3. Prepare the ground and pour

    Once you're ready, we handle any permit steps, and then our crew prepares the ground, pours and finishes the floor while I check in on site. Plan to keep the garage empty until the concrete has cured enough to use.

  4. Walk the finished floor together

    When the job's done, I walk the floor with you and explain how to care for it while it keeps curing. You'll leave knowing when it's ready to walk on and when it's ready for the car.

Common questions about garage floor concrete

How much does a new concrete garage floor cost per square foot in Union City?

A concrete slab in the Bay Area usually costs about $8 to $18 per square foot. That's what slabs generally go for around here, not a quote from us. Where your garage lands depends on its size, how much the ground needs and how the slab is built. You'll get your own figure in writing after I see the floor.

Can I resurface my garage floor instead of replacing it?

Often you can, if the floor is worn on top but still solid underneath. One resurfacer maker designs its product for thin repairs that bring back worn or scaled concrete. Its guide warns that cracks can show back through the new layer, especially where a slab has settled or doesn't have enough control joints. That product also goes only on bare concrete, so paint or sealer on your floor changes the plan.

How long does a new garage floor take to cure before I can park on it?

Concrete takes about a month to fully cure, but you should be able to walk on a new slab within 48 hours. To be on the safe side, it's worth waiting a week before you park a car or roll anything heavy onto it. Plan the garage's downtime around that week.

How do I make sure the ground under a new garage slab is prepared right?

Ask the contractor how they'll compact the ground and how they handle its moisture. One concrete maker advises compacting the ground under a slab at the right moisture, so it supports the slab evenly and doesn't draw water out of the concrete during the pour. A clear answer to that question tells you a lot about who you're hiring.

What is the best way to compare garage floor estimates?

Check that every estimate prices the same kind of slab, because reinforced slabs cost more per square foot than plain pads. One concrete maker also suggests reviewing the slab thickness, how the joints are spaced and put in, and whether you need a vapor barrier, a sheet that keeps ground moisture from coming up into the slab. If one bid leaves those out, ask about them before you compare prices.

Can my general contractor pour my garage floor, or do I need a concrete contractor?

A general contractor can take on the concrete work if they hold the concrete classification or hire a licensed concrete contractor to do it. The state's concrete classification covers forming, pouring, placing and finishing flatwork, the flat concrete like floors, driveways and patios. Before you sign, it's fair to ask who will actually be doing the concrete.

Why Union City homeowners call Professional Union City Concrete for garage floors

  • The owner writes every estimate

    I come out myself to look at the garage and write the estimate, and our crew of finishers and laborers does the work with me checking in on site. That way, the person who priced your floor is also the one making sure it's built the way the estimate says.

  • Licensed and fully insured, easy to check

    We're licensed and fully insured. You're welcome to look up any contractor with the state licensing board before you sign anything, including us.

  • In business since 2021

    I started on concrete crews while I was still in school and opened our business in 2021, after years of learning from the finishers who trained me. Those years taught me that most floor problems start in the ground and the joints, so that's where I spend my attention.

  • Washout kept out of storm drains

    The city inspects construction sites and follows up on complaints about anything washed into the public storm drains. We keep concrete washout and cutting slurry out of the gutter, so your street stays clean and your project doesn't turn into a complaint from a neighbor.

On a garage floor, the part that matters most is the ground under it and where the joints fall. If you'd like me to take a look at yours, request an estimate or call (510) 319-6825.

  • Decorative concrete

    If you'd like your garage floor to look finished rather than plain gray, color, texture and patterned surfaces can make the slab feel like part of the house.

  • Concrete retaining walls

    When your driveway climbs or drops toward the garage, a concrete wall can hold back the slope beside it so soil and runoff stay off the new floor.
