Concrete contractor in Charter Oak, CA - driveways and patios that drain on flat lots
Modern Covina Concrete is a concrete contractor based in Covina that builds driveways, patios, walks and steps in Charter Oak, with the base dug out and packed and each slab pitched so water runs off.
What Charter Oak's streets and lots are like
Charter Oak is a small, flat, mostly residential community between Covina to the west and south and Glendora to the north. It's single-family homes on suburban blocks and cul-de-sacs, with some strip-mall frontage along Arrow Highway and not much else commercial.
Most of our work here is flatwork, the driveways, walks and patios that lie on the ground, and on these lots the hard part is what goes under the slab and where its water goes.
Services in Charter Oak, CA
Concrete driveway building
Old driveways here often sink by the garage where the base was only raked level. We dig out, pack the base and pitch the slab to the street.
Concrete patio construction
Many backyard patios here pool water against the house after rain. We pitch the new slab away from your walls so it drains to the yard.
Concrete steps construction
Front steps here often crack or pull away from the porch as the ground settles. We build new concrete steps on a packed base with steel tied in.
Concrete sidewalk building
Front walks here get lifted and chipped until someone trips on the edge. We tear out the bad sections and pour new ones flush with what stays.
Garage floor concrete
Garage floors here end up cracked and pitted from years of parked cars. We break out the old slab and pour a new one on a rebuilt base.
Concrete cutting
Owners here often want a driveway widened without tearing out the good slab. We saw-cut a straight edge so the new pour meets the old one clean.
Working in Charter Oak: what gets settled before the pour
Charter Oak isn't a city, so LA County is the local government here, and the County's Public Works office issues building permits. Covina's building office only handles addresses inside Covina, and a lot of what people call Charter Oak actually sits inside Covina or Glendora city limits, so I check your address before anything else. When the job needs a permit, we apply for it as the licensed contractor, and that wait comes before the pour, so it usually sets the schedule more than the concrete does. Before you hire anyone, ask for their state contractor license, and know that the County only requires its own business license for the kinds of business on its licensed list. The price moves with the size of the slab, how much old concrete comes out, how much base work the ground needs and the finish you pick, and the written estimate lays out each of those for your job.
On the cul-de-sacs here, the concrete truck usually can't park wherever it wants, so we plan where it sits, how the concrete reaches the backyard and how to keep your neighbors' driveways open on pour day. We leave the street clean when we pack up, the same way we run residential jobs around Covina and in Vincent.
Why slabs here hold water, crack and sink
The ground in Charter Oak is flat, so rain on a driveway or patio doesn't run off unless the slab is built to send it somewhere. We look at where water goes before we set forms, then pitch the slab away from your walls, because a patio that falls toward the house puts water right at your foundation.
The cracked, sunken slabs we tear out here usually have the same story underneath. The subgrade, the dirt the slab sits on, was raked level instead of dug out and packed, so it settled and the concrete went with it. That's the trade-off I'll point out on your estimate. The base is hidden by the end of day one, and it's the first thing people want to trim, but I'd put your money there before a fancy finish, because a nice surface on a soft base still cracks. We also cut control joints, shallow grooves that give the slab a planned place to crack, while the concrete is still fresh, so the cracks land where we choose.

What happens after you call us about a Charter Oak job
Call or send the form
Call (626) 412-8842 or send the form with your address and what's going on with the slab. A couple of phone photos of the cracks or low spots help me plan the visit.
I come out and measure
I come out myself, look at the slab and the ground around it, check where the water runs and measure. It helps if the driveway is clear of cars so I can see the edges.
Get a written estimate
I send a written estimate that spells out what's included, from tear-out and base work to the finish and cleanup. You'll see where the money goes before you decide.
We handle permits and inspections
Once you say go, we confirm whether the County or a city handles your address. When the job needs a permit, we apply for it and set up the inspections.
We pour and walk it together
Our crew forms, pours and finishes the slab with me on site, keeping trucks and mess off the neighbors' driveways. When we pack up, I walk the finished job with you.
Charter Oak concrete questions we hear
Do I need a County permit for a concrete patio in Charter Oak?
Usually, yes, because the County's permit list puts patios and retaining walls under building permits, and grading work is on it too. The list also covers repairs and replacements, so before we quote a patio or driveway replacement, I check what your address needs and you'll know up front whether a permit is part of the job.
How do I find out if my Charter Oak address is County or city for a permit?
Look up your address in the County's Public Works Service Locator, which works for any address in LA County and shows the phone and email of the office to contact. Don't go by your ZIP code, because more than 60 ZIP codes in the County cross County and city lines. If you'd rather not sort it out yourself, I check the address as part of the estimate.
Does a concrete contractor in Charter Oak need a California license?
In almost every case, yes. The state licensing board requires one when the project needs a building permit, uses any extra workers, or runs $1,000 or more in labor and materials, and a bigger job can't be split into smaller contracts to get under that. We're licensed and fully insured.
How much does a new concrete driveway cost in Charter Oak?
It comes down to the size and thickness of the slab, how much old concrete we break out and haul away, and how much base work the ground underneath needs. A driveway carries cars, so it takes more thickness and rebar, steel bars that hold cracks tight, than a patio does, and a plain broom finish, the light texture that keeps it from getting slick, costs less than stamped. If the job needs a County permit, that goes in the price too, and I measure on site so the written number fits your driveway.
When is the first inspection due on a County concrete permit in Charter Oak?
The County wants the first inspection requested within 12 months of getting the permit, and follow-up inspections every 6 months after that to keep the permit active. On our jobs, we set up the inspections, so you're not the one tracking those dates.
How long until I can drive on a new concrete driveway in Charter Oak?
Longer than you can walk on it, because concrete keeps curing, gaining strength as it hardens, for days after the pour, and a car on it too soon can crack or mark it. The exact wait depends on the mix and the conditions after the pour, and I'll give you the walk-on and drive-on dates for your slab. On a cul-de-sac, plan to park on the street for that stretch, and we'll leave you a way to your front door.

Call (626) 412-8842 or send the form while the crack is still small, because water working under a broken slab softens the base and makes the tear-out bigger.
