Concrete floor installation in San Leandro CA - a floor built around how you use it
Old floor cracked, sunken or crumbling? We dig out soft ground, pack the base and pour a new concrete floor made for what it holds.
What does a new concrete floor in San Leandro involve?
Concrete floor installation in San Leandro means our crew forms, pours, places and finishes a new concrete slab for a room, garage, shop or addition. We pour it over ground we've dug out and packed, so the floor stays flat once you start using it.
Most people who call about a floor have an old slab that's cracked, sunk at one end or dusting off, or a new space that needs a floor for the first time. If the old one has to come out first, we handle that with concrete cutting so the break is clean. The price moves with the size of the floor, how thick it has to be for what sits on it, how much steel goes in and how much old concrete or soft ground comes out before we pour. The schedule turns on that same prep, on any permit and on the wait while the concrete cures before you load it. We check early which city or county office covers your address, and when the job needs a permit we handle the application. Your written estimate lays out each option and what it means for your floor.

Concrete floors, pool decks and steps
How we handle concrete floor installation
I start by asking what the floor has to carry, because a laundry room, a shop with a rolling tool chest and a spot for a parked truck each want a different slab. I'm also straight with you that a concrete floor will show some cracking, and the rest of the job is about keeping it small. Our crew digs out the topsoil and any soft spots, then packs the subgrade, the soil the slab sits on, or brings in gravel fill and compacts it, since a slab only stays flat if what's under it does. Rebar, the steel inside the slab, goes in on supports so it sits where it can hold cracks tight instead of lying in the dirt. We pour in the cooler part of the day, because midday heat can leave a weak, dusty top, and after we finish the surface we cut control joints, shallow grooves that give the slab a straight place to crack where we chose. Then comes curing, the wait while the concrete gains strength. If the budget gets tight, I'd rather trim the finish than the base, because nobody sees the base on day one and everybody sees it when it settles. Does that make sense? A pretty finish over soft ground is still soft ground.
A floor job often runs into the work around it. When the new slab ends up higher or lower than a doorway, we can build concrete steps so the rise from the floor is even. If the project heads outside to the pool, our concrete pool decks start from the same dug-out, packed base, and doing both in one stretch of work saves setting up twice.
Why San Leandro owners call us for concrete floors
I measure, estimate and run it
I come out to look at every job myself and write the estimate, and I'm on site running the pour with our crew. The person who heard how you'll use the floor is the one making sure it gets built that way.
Trained on slabs, in business since 2023
I framed houses for years, then learned concrete on a crew forming and finishing slabs before starting this business in 2023. Framing taught me what ends up sitting on a floor, which is why I ask so many questions about yours.
Licensed and insured for city permits
We're fully licensed and insured. The city issues building permits only to a California-licensed contractor or the property owner, so hiring licensed means the permit doesn't land on you.
Cleanup planned for city recycling rules
The city requires residential and commercial projects to recycle or salvage most of their nonhazardous construction and demolition waste. When an old slab comes out, we plan where the broken concrete goes before we break it, so cleanup fits the rule.
On a concrete floor, the ground under it counts for more than anything you'll see on top, so the first step is a look at yours. Ask for a site visit or call (510) 766-7334 with the floor's rough size and what it'll hold.
Get a written estimate for your new concrete floor
Send the form with your floor's rough size and how you'll use it, and we'll reply within one business day to set up a free visit. I measure and write the estimate, with no obligation.

What happens after you call about a concrete floor?
Call or send the form
Call (510) 766-7334 or use the form, and we'll set a time for me to come out. Have the floor's rough size and what it'll hold handy.
I walk the site and measure
I look over the site, measure and ask how you'll use the floor, because a home gym and a parked truck need different slabs. You get a written estimate that explains each option and what it adds, so you can see where the money goes.
We sort permits and prep
Once you pick an option, we look into permits for your address and prep the ground. Prep is the part you won't see later, so it's the part we don't rush.
We pour, finish and explain care
I run the pour and the finish with our crew. When we're done, I walk you through how to care for the floor while it cures and after.
Concrete floor questions from San Leandro
How much does a concrete floor cost in the Bay Area?
A reinforced concrete slab in the Bay Area usually costs about $9 to $16 per square foot, without staining or stamping. One Bay Area guide prices reinforced slabs higher than plain, un-reinforced pads, so the steel is part of that number. Your written estimate shows where your floor lands and what each option adds.
Will a new concrete floor crack, and does rebar stop it?
Some cracking is normal, and so is a little curling at the edges, because no concrete floor is free of both, even with the best design and building methods. Wire mesh or rebar can't prevent cracks, but set at the right spot in the slab it keeps them narrower. Ask any contractor where the steel will sit in your floor, and judge the finished floor with that in mind.
How long does a new concrete floor take to cure before I can use it?
You should be able to walk on a new slab within 48 hours, but concrete takes a month to fully cure. To be safe, you may want to wait a week before putting heavier loads on it, so plan when the shelves, tools and furniture come back in.
Where do I apply for a building permit for a concrete floor in San Leandro?
You apply at the city's Permit Center at City Hall, which takes building permit applications. Plans and a soils report are typically required whenever new construction work is proposed. The state and the city have also added local requirements to the building code, including earthquake design standards for structural work, so a floor that's part of new construction gets planned to them from the start.
Does a commercial concrete floor need to be thicker than a home floor?
Yes, commercial floors, industrial uses and foundations need thicker slabs than residential floors, and they cost more. That's why I ask what the floor will carry before I price anything.
How do I know if my concrete floor job needs a licensed contractor in California?
California requires a contractor license for work that builds or alters a structure when the project needs a building permit or uses additional workers, and also when labor and materials total $1,000 or more. The state licensing board's concrete class covers forming, pouring, placing and finishing flat concrete work, which is what a floor is.
Work that goes with a new concrete floor
Concrete pool decks
If your project runs outside to a pool, the deck needs the same packed base plus a slope that sends splash water away from the house.
Concrete steps construction
When a new floor changes the height at a doorway or back entry, solid concrete steps give you an even climb that matches the new slab.
