Garage floor concrete in San Leandro CA - a slab built for how you use your garage
Cracked, dusty or sinking garage floor? We pour a new slab planned for your car, storage and coating, on ground that's packed firm.
What does it take to pour a new garage floor in San Leandro?
Garage floor concrete in San Leandro means taking out a worn or cracked floor where there is one and pouring a new slab built for how you actually use the garage, whether that's parking, a workshop, heavy shelving or a coated floor.
Most people call us because the old floor is cracked, sinking in spots or chipping and dusting up, or because they want a coating or a car lift the current slab wasn't built for. The price mostly moves with the size of the garage, whether an old floor has to come out, and how much weight the slab has to carry, since a thicker slab with steel or a moisture barrier under it costs more than a plain one. The schedule turns on whether a permit is needed and on curing, the wait while fresh concrete hardens before it can take a car. My written estimate lays out each option and what it means, so you're deciding with your own garage's numbers in front of you.

Garage floors and the concrete around them
How we build garage floor concrete
A garage floor should be built for what you'll do in it, so I ask about coatings, a car lift or heavy storage before we price the slab, because each one changes the thickness, the steel and what goes underneath. If there's an old floor, we break it out and haul it off, then dig out and pack the subgrade, the soil the slab sits on, because a base that's only raked level settles with the dirt and takes your new floor down with it. We set the forms, lay rebar, the steel bars that hold the slab together if it cracks, wherever your loads call for it, and we pour in the cooler part of the day, since a slab finished in midday heat tends to end up with a weak, dusty top. We finish it smooth for a coating or with a broom finish, a light brushed texture that gives tires and shoes some grip, then cut control joints, shallow grooves that give the slab a planned place to crack as it shrinks, before it picks its own spots. If the budget is tight, I'd rather you spend on the base than the finish, because the base is the one part nobody can get back to once the concrete is on top of it. We also help you plan where the car and your stored things go while the new floor cures.
Garages rarely stand alone. If you want the floor or the walk to the door to look like more than plain gray, our decorative concrete work can be planned along with the slab, and on a lot where the ground rises beside the garage, concrete retaining walls keep that dirt where it belongs. If your project has a piece I haven't covered, bring it up at the estimate.
Why San Leandro homeowners call Complete San Leandro Concrete for garage floors
I write every estimate myself
I come out to look at every job myself and write the estimate after measuring and hearing how you'll use the garage. That way the person pricing your slab is the same one who heard about the lift or the epoxy you're planning.
Learned on a concrete crew
I framed houses for years, then learned this trade forming and finishing slabs on a concrete crew before I started this business in 2023. I'll tell you why we do each step, so you can look after your floor and judge the work fairly.
Fully licensed and insured in California
The California Contractors State License Board requires a state license when a job needs a building permit, uses employees, or comes to $1,000 or more in labor and materials, and we're fully licensed and insured. Ask any contractor you're comparing about their license before you start weighing their prices.
Permit question settled up front
We check early which office covers your address, and for a San Leandro home that's the city, whose Permit Center at City Hall takes applications in person and reviews plans for new construction before it issues a permit. When a job needs a permit, we handle the application and set up the inspections with you, so a review doesn't surprise you after a pour date is set.
On a garage floor, the ground under the slab matters more than the shine on top. Send us the form with your garage size, any coating or lift plans and the shape the current floor is in, or call (510) 766-7334.

What happens after you call about a garage floor in San Leandro?
Call or send the form
You call (510) 766-7334 or send the form, and we set up a time for me to come see the garage. It helps to have the garage size, any coating or lift plans and a few words about the current floor ready.
I measure and ask questions
I come out myself, look over the floor and the ground around it, and ask how you'll use the space. You get a written estimate that explains each option, like steel or no steel, and what it does to the price.
We sort permits and prep
Once you choose, we take care of the permit steps we checked at the start, then our crew breaks out any old floor and digs out and packs the ground. This is also when we settle where the car and your stored things will go during the cure.
We pour, finish and explain
Our crew does the pour and the finish with me on site running it. Then I walk you through how to care for the new floor and when it's ready for the car.
Questions about garage floor concrete
How much does a new concrete garage floor cost in San Leandro?
A concrete slab in the Bay Area usually costs about $9 to $18 per square foot installed, and one Bay Area cost guide puts a reinforced slab higher per square foot than a pad without steel. That's the going rate around here, not our price, so for your own garage we measure it and give you a written estimate with each option laid out.
How long does a new garage floor need to cure before I can park on it?
A new slab should be walkable within 48 hours, and one Bay Area guide suggests waiting a week before putting the car or other heavy loads on it. The concrete keeps curing for a month, well past that first week, so plan another spot for the car and heavy stored things for at least the week.
How thick should a garage floor slab be?
Slabs for residential floors typically run 4 to 6 inches thick, and the right one for your garage depends on what it has to hold. If a car lift is anywhere in your plans, one guide says to plan the thickness and the joint layout around where the lift posts will go, so tell us about it before the pour.
Will my new garage floor crack like the old one?
Concrete can still crack as it shrinks, settles or carries heavy loads, and industry guidance is that slabs carrying significant weight or thicker than 4 inches will often need reinforcement to handle those. What you plan to park or store decides whether steel belongs in your quote, and I'll show you that choice on the estimate.
Do I need a vapor retarder under my garage floor?
You'll want one if the floor will get an epoxy or polyaspartic coating or become a heated, finished room, according to one garage slab guide, because a vapor retarder is a barrier under the slab that limits moisture coming up from the soil. The same guide says a bare broom-finished floor in an unheated garage goes without one, so your plans for the floor make the call.
How do I get rid of an old concrete garage floor in San Leandro?
In San Leandro, the city's construction recycling rules call for recycling all of the old concrete and asphalt from a job and keeping at least 65% of other debris out of the landfill. The city also assigns waste haulers by service area, so a debris box has to come from the hauler designated for your address, and we plan the tear-out and haul-off around both.
Work that goes with garage floor concrete
Decorative concrete
Color, scored patterns or a textured finish can give the slab or the area outside the garage door a look that matches the rest of the house.
Concrete retaining walls
When the garage or the driveway leading to it is cut into a slope, a poured wall keeps the hillside soil from pushing in or washing down.
