Services in Chino Hills, CA
Concrete driveway building
Many driveways here climb steeply from the street, so rain runs hard across them. We dig out, pack the base and pitch the slab away from the garage.
Concrete retaining walls
Hillside lots here often need a wall where the yard was cut into the slope. We pour on solid footings and give water a way out behind it.
Concrete steps construction
Hillside yards here often sit on two or three levels. We form and pour concrete steps between them with even risers and a textured top for grip.
Concrete patio construction
Backyard patios here often back onto a slope that sheds water in storms. We pitch the slab away from the house and cut joints to guide cracks.
Concrete pool decks
A lot of yards here have a pool ringed by a deck that takes splash and bare feet. We slope it to drain and texture it so wet feet hold.
Stamped concrete services
Front walks and patios on the newer houses here call for more than plain gray. We stamp and color the slab after the base and joints are right.
Chino Hills, CA properties and local conditions
Rain is the big one here. The hills, along with the way the streets and storm drains carry water, mean a heavy storm can flood roads and even start slides, and on your lot that same water comes down hard across the driveway and around the patio. Water that gets under a slab softens the subgrade, the ground the slab sits on, and that's when you start seeing sinking, cracks and puddles that weren't there last year. So before we set a single form, we look at where the water goes, slope the new slab toward the street or a drain, and make sure it has somewhere to go other than under your concrete.
Most lots here were cut into the hill, with part of the yard sitting on dirt that was moved and filled in. Fill that wasn't packed well keeps settling, and a slab poured on top settles right along with it. We dig out soft ground and pack a real base, and where the grade change is big, we'll talk about a wall or steps instead of forcing one flat slab onto a slope.
Working in Chino Hills: permits, licenses and what moves the price
Building permits in Chino Hills come from the city's Building and Safety Division, and that's the office to ask whether your concrete job needs one, because the city's rules talk about buildings and structures, not driveways and patios. When a job does need a permit, nothing gets poured until it's issued, so it's the first thing that sets the start date. Two licenses are worth checking on anyone you hire. The state requires a license from the Contractors State License Board when the work needs a building permit, uses employees, or adds up to $1,000 or more in labor and materials, which covers most concrete jobs. A contractor based outside the city also needs a Chino Hills business license, and since the city's fee for that is $17.83, there's no good reason to skip it. We're fully licensed and insured.
Price here follows the ground more than anything. A sloped lot means more digging and hauling, sometimes a wall or steps to handle the grade, and some planning to get the truck close on the steeper streets, and the finish you pick adds on top of that. The schedule turns on the permit and the forecast, since we won't pour with a storm coming. Your written estimate spells out both for your job. We're based in Pomona and do the same work down the hill in Chino, where the lots run flatter and the ground asks for less.

(909) 729-4086How it goes when you call us about a job in Chino Hills
Call or send us a message
Call (909) 729-4086 or use the form and tell us what you've got, whether it's a driveway that's sinking or a slope that needs a wall. We'll set a time for me to come out to your place.
I look at the ground first
I check the ground, see where the water runs, measure and ask how you'll use the space, and it helps if you're home to show me where water sits after rain. Then you get a written estimate that spells out the base and drainage work, not just the surface, so you can compare bids on what matters.
We handle permits and pour
If the job needs a permit, we pull it and handle the paperwork with the city, and the pour waits until it's issued. My crew forms, pours and finishes, and I'm on site to check the work.
We walk the job together
Before we pack up, we walk the finished job with you and look over the edges, joints and drainage. I'll tell you when you can walk on it and when you can drive on it, because the concrete needs time to cure first.
Frequently asked questions
Do I need a permit for a concrete driveway or patio in Chino Hills?
The city's rules don't give a flat yes or no for flatwork like driveways and patios, so it's worth checking for your job. What the city does say is that grading or excavation of any kind needs a permit first, apart from a few listed exemptions, and a grading permit is only issued once the project has its zoning approvals. That's why we settle the permit question before we book a pour date.
Do I need a permit to replace the sidewalk or curb in front of my house in Chino Hills?
Yes, work in the public right-of-way, which covers sidewalks, curbs, gutters and the street, needs an encroachment permit, the city's OK to work on public ground. If your driveway job reaches the sidewalk or curb, plan on that piece needing one.
Does a concrete retaining wall need a permit in Chino Hills?
Often it does, because the exemption only applies when a wall meets every condition on the city's list of work exempt from permits. A concrete wall up to 4 feet tall, or a retaining wall holding back less than 3 feet of soil, is exempt only if the soil behind it slopes gently, no nearby structure puts weight on it, it holds back no fuel or similar liquids, and every part sits more than 5 feet from the property line. On a hillside lot, the slope behind the wall or the property line often rules that out.
How much does a concrete driveway cost in Chino Hills?
It comes down to size and, more here than in flatter cities, the ground under it. A sloped lot means more digging, hauling and base work, and truck access, tearing out an old slab, thickness, and a stamped or colored finish all add to it. If something has to give, keep the money in the base and go simpler on the finish, because the base gets buried the day we pour and it decides whether the slab stays flat. Your written estimate gives you the number.
How long does a new concrete driveway take before I can use it?
Pour day is the short part, and the wait comes from any permit before it and the curing after it. Curing is the stretch where concrete hardens and gains strength, and keeping weight off it then is what keeps the top from cracking or going dusty. You'll walk on it well before you drive on it, and since rain can push a pour here, we watch the forecast and set the date around it.
What causes concrete to crack and sink on hillside lots in Chino Hills?
Usually it's the ground, not the concrete. A base that was raked level instead of dug out and packed settles with the dirt, and on fill, or where storm water gets underneath, that happens faster. Cracks that wander across a slab usually mean the control joints, the cuts that tell concrete where to crack, went in late or not at all. Concrete cracks, and the joints decide where, so we cut ours on time and spend the most effort on the part you'll never see.
About Chino Hills, CA
Chino Hills is mostly houses on rolling ground, with streets that wind up and over the hills and open hillside left between the neighborhoods, a lot of it out toward Chino Hills State Park. Many homes sit on pads cut into a slope, so the street, the front yard and the backyard can all be at different heights. It reads a lot like Diamond Bar next door, and we get the same calls in both, mostly sinking driveways, cracked patios and slopes that need a wall.
That's why a job here starts with the ground. On a flat lot the base is part of the work. Up here it's most of it, and it's the part I won't trim to win a bid.
