Ontario homes and the concrete work they need
The short answer: Yes, Covina Concrete works in Ontario, CA. We're a concrete contractor best known for driveways, patios and flatwork, which covers the walks, slabs and steps that sit on the ground around a house. We also take on foundations, retaining walls, cutting and small parking lots for landlords and business owners in Ontario.
Ontario is a big city, and the calls we get there run from older single-story houses still on the driveway they were built with to newer homes where the builder left a narrow walk and a back yard of dirt. In between are plenty of rentals, plus shops and small business lots with a broken slab out front. It's much the same mix we see next door in Pomona.
Most lots here are flat, so the job rarely turns on a hill. It turns on what's under the old concrete and where the water goes, and on older houses those two things usually explain why the slab failed.
Why Ontario driveways and patios give out
Water is the first thing I look at on an Ontario patio or driveway. On a lot of houses here, an old slab has sunk next to the house or was poured falling toward it, so rain runs back against the wall and sits in a puddle by the door. Before we set a single form, we work out where the water should go and build the new slab to carry it away from the house.
Rentals and small business properties take a beating from cars, trash bins and years of put-off repairs. For those, we'd usually rather cut out and replace the worst sections cleanly than patch the whole thing, because a patch over a broken base comes back.
Concrete services we offer in Ontario
Concrete driveway building
When an Ontario driveway has sunk, split or holds water at the garage, we tear it out, dig to firm ground, pack a new base and pour.
Concrete patio construction
For a back yard that's still dirt or an old patio that tips toward the house, we pour a slab sloped to carry rain away.
Stamped concrete services
Stamped concrete pressed with a stone or brick pattern suits a front walk or back patio when you want more than a plain gray slab.
Concrete sidewalk building
Cracked or lifted walks from the driveway to the front door trip people up, so we replace the bad sections and set them flush with what stays.
Garage floor concrete
A garage floor that's pitted, oil-soaked or broken around the door can be cut out and repoured, with the slope kept running toward the opening.
Decorative concrete
Colored concrete, a top that shows the stones in the mix, or a border around a plain slab can dress up a front entry.
Concrete retaining walls
Where a yard steps down or soil is pushing against a fence or slab, a concrete wall holds the dirt back, and we plan drainage behind it.
Concrete floor installation
For a new room, a converted garage or a shop space, we pour an interior floor that's flat, level and ready for whatever goes on top.
Concrete pool decks
Around a pool, the deck has to drain away from the water and give bare feet some grip, so we finish it with a texture that isn't slick.
Concrete steps construction
Front steps that have settled away from the porch or vary in height are worth redoing, because a step that's off by an inch catches toes.
Slab foundation building
For an addition, a back house or a garage on your lot, we pour the slab foundation it sits on, with the steel and base the plans call for.
Foundation installation
When a building needs more than a slab, like a raised floor on a short concrete wall, we form and pour the foundation to your plans.
Concrete parking lot building
For a small business or a rental with a shared lot, we replace broken parking areas with slabs thick enough for daily car traffic.
Concrete footings
Patio covers, block walls and posts need footings, the concrete pads or trenches that carry the weight down, and we dig and pour them to size.
Foundation raising
If a slab or a section of foundation has dropped and left cracks or a sloping floor, raising it can sometimes cost less than tearing it out.
Concrete cutting
We saw-cut clean openings for a new walk, a drain line or a wider driveway, so only the part that has to go comes out.

What we deal with on Ontario concrete jobs
When a concrete job in Ontario needs a permit, it comes from the city's Building Department, which reviews the plans and inspects the work, and nothing goes on our calendar until it's issued. We first check whether your address is under the city or the county, since that decides which office we work with, and then we pull the permit as the licensed contractor and set up the inspections. Before you hire anyone, ask for two things, a current California contractor license and an Ontario business license, which the city requires of contractors based outside Ontario as well as inside it. We're fully licensed and insured.
What moves the price is mostly the size of the job, whether an old slab has to be broken out and hauled away, how much digging and base work the ground needs, how thick the slab is, how much steel goes in it and the finish you choose. Access matters too, because a back patio behind a narrow side yard means wheeling or pumping the concrete past the house, and on a busy street we have to plan where the truck sits. The schedule turns on the permit, if there is one, and on how much tear-out comes first, and your written estimate gives you your own figure with everything it covers. We price jobs the same way in Citrus and the other cities around Covina.
How a concrete job goes when you call us in Ontario
Here's how a concrete job in Ontario runs once you reach out, from the first call to the final walk-through, and who you'll be dealing with along the way.
- Step 01
Call and talk it through
Call us or send the form, and we'll talk through what you want poured and what's wrong with what's there now. Then we set a day for me to come out.
- Step 02
I measure and write the estimate
I walk the job, measure it and look at the base and the drainage, and it helps if you're home so we can go over it together. You get a written estimate that lists what's included, so you know what the price covers before you decide.
- Step 03
Permit first, then the schedule
If the job needs a permit, we get it and set up the inspections before anything goes on the calendar. The city's plan review sets that part of the timeline, and I'll tell you where it stands.
- Step 04
Pour day and final walk-through
Our crew forms, pours and finishes the job, and I'm on site for the pour. Once it's done we walk it with you, and I go over how long to keep feet and cars off while it cures, which is the wait while the concrete hardens and gains strength.
Questions about concrete work in Ontario
How do I know if my concrete job in Ontario needs a licensed contractor?
In California, you need a state-licensed contractor for any job that needs a building permit, uses hired workers, or comes to $1,000 or more in labor and materials combined. The state licensing board only exempts jobs that need no permit, use no employees and total less than $1,000, and a bigger job can't be split into smaller contracts to get under that line. Ask for the license number before you sign anything.
How much of a down payment can a contractor ask for in California?
Under the state licensing board's rules, a contractor can't ask for or take more than $1,000 or 10 percent of the contract price as a down payment, whichever is less. After that, payments are listed in the contract and tied to work done or materials delivered. That holds for every home improvement job, a driveway or patio in Ontario included.
How much does a new concrete driveway cost in Ontario, CA?
The price comes from your driveway's size and what's under it, so I give you a number only after I've measured. The biggest swings are the ones covered above, mainly tear-out, base work, thickness, steel and the finish. Your written estimate spells out each one.
What causes concrete driveways in Ontario to crack and sink?
Most of the cracking and sinking we see starts under the slab, with a base that was raked level instead of dug out and packed, so the concrete dropped as the dirt settled. The rest usually comes from control joints cut late or skipped, and those are the grooves that make a slab crack along a line we chose instead of across the middle. Concrete shrinks as it cures, so we pack the base, cut the joints on time and pour early on hot days, because concrete that dries too fast in midday heat ends up with a weak, dusty top.
How much does it cost to extend a building permit in Ontario?
The first extension on a plan check or permit in Ontario is free, and each extension after that costs $150 on a residential permit or $300 on a commercial or industrial one. Those fees only come up when a job drags on, so we line up the crew and the pour once the permit is in hand.
Is stamped concrete worth it for a patio in Ontario?
It can be, as long as the money for it doesn't come out of the base, because a stamped top on a base that wasn't dug out and packed cracks and sinks like any other slab. If the budget is tight, I'd spend it on the base and the rebar, the steel bars that hold the slab together, and go with a broom finish, the light brushed texture that gives shoes some grip. The base is the one part you can't go back and fix without breaking the slab out.
