Concrete contractor in Azusa, CA - driveways and patios built for foothill ground
Modern Covina Concrete is a concrete contractor based in Covina that pours driveways, patios, walkways, steps and retaining walls for homeowners in Azusa, with the base dug out and packed before any concrete goes down.
How Azusa's houses and ground shape the work
Azusa sits right up against the San Gabriel foothills in LA County, and you see that on the jobs. The flatter streets are mostly older single-story homes with driveways and walks that have been down a long time. The closer you get to the hills, the more the lots slope, so water runs across the slabs toward the street or toward the garage. We're a concrete contractor based in Covina, CA, a short drive away, and we see the same mix in Glendora and back home in Covina.
That's why most flatwork here, the driveways, patios and walks we pour on the ground, starts with grade and drainage and gets to the finish last. On a sloped lot the slab has to carry water away from the house, and under an old one the dirt has usually moved.
Services in Azusa, CA
Concrete driveway building
Older Azusa driveways often sink because nobody packed the base. We break out the old slab, compact new base and pour with a swept broom finish for grip.
Concrete patio construction
Backyards on sloped lots tend to send water toward the house. We set the patio to drain away from your walls before we think about the finish.
Stamped concrete services
Plenty of homeowners here want a walk or patio that looks like stone. Our stamped concrete services give you that on a new slab, prepped like any other.
Concrete retaining walls
Foothill lots often need a wall to hold back a slope or level a yard. We build them on proper footings with steel inside and drainage behind.
Concrete steps construction
Houses set above the street lean on their front steps, and old ones start to tip. We form new steps with even step heights and footings under them.
Concrete footings
Garage additions and patio covers on older lots need footings that reach firm soil. We dig, set the steel and pour them to the approved plans.
What we check before a concrete job in Azusa
Azusa handles its own permits through the city's Building Division, and the city asks for a building permit whenever a structure is built, altered, repaired or torn down. Its list of exempt work names things like small sheds, low fences and short retaining walls, not driveways or patios. So I check your job with the city before we schedule anything, because a permit adds the city's sign-off and inspections to the timeline. On bigger work, like a slab for an addition, the first stop is the city's Planning Division, to see whether it needs design review. Before you hire anyone, check two things, a state contractor's license and an Azusa business license.
Price and schedule here mostly come down to the ground and the access. The price moves with the size of the slab, how much old concrete we break out and haul off, how deep we dig to reach firm dirt, how far we wheel concrete from the truck on a tight driveway, and the finish you pick. A permit or a rainy week moves the start date. It's the same on the older streets in Baldwin Park, and in both places I measure on site and put it all in a written estimate that spells out what's included.
Why slabs on Azusa lots crack, sink and hold water
Parts of Azusa sit in earthquake fault zones, and other parts are in zones the city marks as prone to liquefaction, where wet ground can loosen in a quake, or to landslides. That doesn't change much on a patio. Before we plan footings, a retaining wall or a slab foundation, though, I check where your address falls, because it can change what the plans need.
The more common problem is the subgrade, the dirt and gravel the slab sits on. On a sloped lot, water gets under an old driveway and softens or washes out what's below it, and the slab settles with it. So we dig down to firm ground, pack the base in layers and set the grade so water runs off toward the street instead of into your garage.

How a concrete job in Azusa goes once you call
Call or send a message
Call (626) 412-8842 or use the form and tell us what's going on with the slab. A couple of photos of the cracks or the pooling water help me know what to look at.
I come out and measure
I come out myself to look at the slope, the drainage and the old concrete, and I check your address to see whether the city or LA County handles the permit. Move the cars off the driveway if you can, so I can see the whole slab.
You get a written estimate
I send a free written estimate that spells out what's included, from tear-out and base work to the finish. Nothing starts until you say go.
We handle permits and inspections
If your job needs a permit, we apply for it as the licensed contractor and set up the inspections with the city. Plan on that adding time before the pour.
We pour and walk it together
Our crew does the work with me on site, and we keep the mess off your neighbors' driveways and clean up when we pack up. Then I walk the finished job with you and tell you when you can walk and drive on it, because new concrete needs time to cure, or harden, before it takes weight.
Questions about concrete work in Azusa
How much does a new concrete driveway cost in Azusa?
I price each driveway in Azusa after I've seen it, because what's under the old slab and how much of it has to come out matter as much as the size. Stamped or colored finishes raise the price, and a plain broom finish keeps it down. If the budget's tight, cut the finish, not the base, because nobody sees the base on day one and it's what decides whether the slab settles. Call (626) 412-8842 and I'll come out and put a number in writing.
What causes a concrete driveway to crack in Azusa?
Most cracks come from the ground moving under the slab or from the concrete shrinking as it dries, and the bad ones usually trace back to a base that was raked flat instead of dug out and packed. Concrete will crack somewhere. That's why we cut control joints, shallow grooves that give it a straight place to crack, while it's still fresh, and set rebar, steel bars that hold the pieces together. On a packed base with joints cut on time, a new slab usually cracks in the joints, where you'll hardly notice it.
How do I know if my retaining wall needs a permit in Azusa?
Plan on a permit if the wall is taller than 4 feet, measured from the bottom of its footing to the top of the wall, or if it holds up extra weight like a slope or a driveway above it. Shorter walls with nothing pushing on them are on the city's list of work that doesn't need a building permit. Most people measure from the yard, which leaves out the footing, so I measure it when I come out.
Does a small shed need a permit in Azusa?
A one-story detached shed or playhouse up to 120 square feet is on the city's exempt list for a building permit. If you're running power or water to it, that still needs its own electrical or plumbing permit, because the city requires those separately even when the building permit is waived. If you want a slab under the shed, I'll check that with the city before we pour.
Does a contractor based outside Azusa need a city business license?
Yes. The city requires every business located or working in Azusa to get a city business license before doing business there, and that includes companies based outside the city limits. That applies to us, since we're in Covina, and it's fair to ask any contractor you're considering. The city's business licensing page is where to look into it.
When does a concrete contractor need a state license in California?
A contractor needs a license from the Contractors State License Board when a job needs a building permit, uses employee labor, or adds up to $1,000 or more in labor and materials across one or more contracts. Any job done with a crew falls under that, so ask for the license before you sign. We're licensed and fully insured.
