Garage floor concrete in Menlo Park CA - a level floor on firm, packed ground
Cracked, sunken or uneven garage floor? We dig out, pack the ground and pour a new slab that sits level and drains out the door.
A garage floor is flatwork, the flat slabs we pour for floors, driveways and patios, and it carries more weight than most of them. People call us about garage floor concrete in Menlo Park when the old slab has cracked across, sunk by the door or started holding water, and the trouble usually started in the ground under it, not in the concrete.
So compaction under the slab gets our closest attention. Price moves with the garage's size, whether an old slab has to come out, how much ground needs packing and what you plan to do with the floor later, and the schedule turns on what the city asks for and the curing wait before you load it up. Your estimate puts all of that in writing.
What our garage floor concrete work covers
- Estimate and job run by me. I come out and write the estimate myself, then run the job on site while our crew works. I started this business in 2023 after learning the trade on other people's crews.
- Ground dug out and packed. We haul out the old slab, dig to firm soil and pack the subgrade, what the slab sits on, in layers, because uneven ground is what cracks a garage floor.
- A slope toward the door. We set the forms so the floor falls gently toward the door, and check that fall before we pour, because water that sits on a garage floor finds every crack.
- Joints cut on time. We cut control joints, grooves that give the slab a straight line to crack along, as soon as the concrete is firm enough, because joints cut late leave cracks where nobody chose.
- Licensed and fully insured. We're licensed and fully insured, and you're welcome to ask for proof of both when I come out to write the estimate.
What goes wrong with garage floors
| Problem | What it looks like | Usual fix |
|---|---|---|
| Cracks across the floor | What it looks like: Lines running wall to wall, sometimes with one edge sitting higher | Usual fix: Break out, repack the ground, pour a new slab |
| Sunken section | What it looks like: A low spot near the door where water collects | Usual fix: Cut out the section, pack the ground, repour |
| Water at the back wall | What it looks like: Damp concrete along the back wall after a hard rain | Usual fix: Regrade outside, or hold back the slope with a concrete retaining wall |
| Dusty, flaking top | What it looks like: Gray powder on your shoes and chips where the tires roll | Usual fix: Grind and coat if sound, otherwise replace |
Repair part of it or pour new
- Seal the cracks. If the floor is still level and the cracks are thin, sealing them keeps water and oil out, though it won't stop ground that's still moving underneath.
- Replace one section. When one area has sunk, often by the door, we cut it out, pack the ground and pour that piece new, knowing the new concrete won't match the old in color.
- A new floor. If it's cracked all over or slopes the wrong way, I'd replace it, because patches sit on the same bad ground, and decorative concrete finishes can go on later.
How a garage floor job runs
- You get in touch. Call (650) 582-0556 or send the form with your garage's size and plans, and we'll set a time for me to come out.
- I look and write it down. I measure, check the ground, nearby trees and where water runs, then write in plain words what we'll build before I put a price on it.
- Permits, then forms. We sort out what the city for your address asks for before setting a date, then set and check the forms before any concrete is ordered.
- Pour, clean up, walk through. We pour and finish, wash tools and the mixer only in a set-aside spot away from the driveway, street and gutters, as the county's stormwater guidance asks, then walk the floor with you.
Keeping your garage floor sound afterward
Concrete can crack a little even when it's built right, and I'd rather tell you now than have you find out later. The control joints give those cracks a straight line to follow, so keep the joints sealed, wipe up oil before it soaks in, and hold off on heavy loads for the wait the questions below explain.
We pour garage floors for homeowners in Menlo Park and the cities around it, from San Mateo down to Cupertino and beyond, including Redwood City and Palo Alto. Call or send the form, and I'll come out to look at your garage and write you an estimate.

Garage floor questions we hear
How much does a new concrete garage floor cost in the Bay Area?
A reinforced concrete slab in the Bay Area usually costs about $9 to $16 per square foot, going by one regional cost guide, and that's the market's range, not our price. Your estimate spells out the thickness, since floor slabs for homes typically run 4 to 6 inches.
How soon can I walk on a new concrete garage floor?
A new slab should be walkable within about 48 hours, and waiting a week before heavier loads is the safe choice. Concrete keeps curing, slowly hardening, for about a month, so plan where your boxes, tools and anything heavy go for that first week.
When can I epoxy or coat a new garage floor?
Plan the coating as a later step, because a floor that looks dry can still be too young or too dirty for a coating to hold. Moisture, oil, curing compounds and chemicals from tires all affect how well it sticks. Tell us before the pour, since a vapor barrier under the slab may matter for a coated floor.
Do I need a permit for a new garage floor in Menlo Park?
We check that for each address before we set a date, against the city's list of work exempt from building permits. If a permit is needed, Menlo Park takes building permit applications online only, with digital plans, and we handle the paperwork or help you with it and don't start until it's in place.
What license does a concrete contractor need in California?
California's C-8 Concrete Contractor classification is the one for forming, pouring, placing and finishing concrete, flat slabs like a garage floor included. The state lets someone work without a license only on minor jobs up to $1,000 that need no permit, with no one employed on the job. You can check a contractor's license with the state licensing board.
