Concrete work in Fullertonfrom a crew based in Diamond Bar
Most Fullerton calls start with something you can see, like a driveway cracked across the middle or a patio that holds water. We're based in Diamond Bar and do the same work next door in Anaheim and back home in Diamond Bar.
Price moves with the size of the job, how much old concrete we break out and haul off, how much the ground needs before we pour, and the finish you pick. The schedule turns on the city's permit answer and the weather. Your estimate spells out what's in the price.

Concrete services in Fullertonfor homes and small businesses
We bring the same crew and the same ground prep to every job in Fullerton, from a single set of steps to a small business lot.
- Concrete driveway building Cracked or sinking driveways come out, the base gets dug and packed, and the new slab drains to the street.
- Concrete patio construction Backyard patios pitched away from the house, so rain runs off instead of pooling by your back door.
- Stamped concrete services Stamped patterns that look like stone or brick, laid over the same packed base as any plain slab.
- Concrete sidewalk building Front walks and side paths replaced when roots or settling have lifted an edge people trip on.
- Garage floor concrete Garage floors built for a parked car and a workbench, with a smooth top that sweeps clean.
- Decorative concrete Colored and textured concrete for entries and yards where plain gray would look out of place.
- Concrete retaining walls Retaining walls for yards that step up or down, built with drainage behind them so water doesn't push them over.
- Concrete floor installation Interior concrete floors for additions, workshops and small commercial spaces, finished flat for whatever goes on top.
- Concrete pool decks Pool decks with a broom finish, a light texture that gives wet feet grip, sloped away from the water.
- Concrete steps construction Front and back steps rebuilt with even risers, because one tall step is the one everybody trips on.
- Slab foundation building Slab foundations for additions and outbuildings, set on packed ground with rebar, the steel that holds the slab together.
- Foundation installation Foundations for new structures on your lot, built to the design the job and the site call for.
- Concrete parking lot building Parking lots and aprons for small businesses that need a surface that takes daily traffic and drains.
- Concrete footings Footings for patio covers, walls and posts, dug to the depth the plans call for.
- Foundation raising Sunken slabs and settled foundations looked at first, so we can tell you whether raising makes sense.
- Concrete cutting Clean saw cuts for drain lines, door openings or pulling one bad section instead of the whole slab.
Why Fullerton calls usthe parts nobody sees, done right
You deal with me from the first look to the last sweep. If there's bad news, you hear it first, and I'll tell you why each step matters.
The owner works your job
I work alongside our crew on the job itself, so the person who looked at your ground is there when the base goes in and the concrete gets placed.
The base comes before the finish
Ground prep is buried on day one, so it's the first budget cut people suggest. I'd drop the fancy finish first, because a slab on loose dirt settles with it.
Water that runs away from the house
We check where your water goes before we form anything and pitch the slab away from your walls, so rain doesn't sit against the house.
Licensed, insured, permits checked first
We're fully licensed and insured. Fullerton's Building Division generally requires permits for patios and retaining walls, and other work is the city's call, so we check before setting a date.
Honest about what you need
If one cracked section can be cut out and replaced, I'll say so before quoting a whole new driveway. Satisfaction guaranteed on every job.
From your call to cleanuphow a Fullerton job runs
I'm the one who measures your job, writes up the price and works the pour with our crew, so you're never relaying messages between a salesman and the people doing the work.
You call or message us
Tell us what you're seeing, like a cracked driveway or water pooling by the house, at (909) 760-1399 or through the form, and we'll get back to you.
I measure and write it up
I come out myself to look at the ground and measure, then write an estimate that says what's in the price and what isn't, like hauling off the old concrete.
Permit, date, then the pour
We settle the permit question with the city and set a date, and I'm on site with our crew from forming to cleanup. Smaller projects can often be reviewed at the city counter, though bigger ones may get a closer look.
We walk it with you
We go over the finished slab together and talk through curing, the wait before you walk or drive on it, because new concrete needs time to gain its strength.
What Fullerton asks of concretecode, sun and shrinking slabs
Here's what Fullerton's code, the afternoon sun and the concrete itself ask of a new slab, and how we handle each.
Earthquake design for structural work
The city rates structural work like footings and walls in Seismic Design Category D, E or F by site, and we build to match.
Midday heat on a pour
Concrete placed in midday heat dries too fast on top and goes weak and dusty later, so we plan pours for the cooler hours.
Cracks in planned places
Concrete shrinks and cracks somewhere, so we cut control joints, grooves that tell the crack where to go, on time instead of days late.
Your Fullerton estimatemeasured and written up by me
Tell us what you want poured or fixed, the rough size, and anything you've noticed like cracks or pooling water. We respond within one business day to set up your free on-site estimate, with no pressure and no obligation.
Our work in Fullertonand what it takes here
Fullerton people spend a lot of time outside, on the trails and at places like Hillcrest Park, and at home that shows up as calls for patios, walks and steps that get used every day. We build those to take that use and still drain right.
Working here also means following the city's rules. Fullerton requires anyone doing business in the city to hold a business registration certificate, and it may ask for proof of a state license before issuing one, so it's fair to ask any contractor about both before you sign.
