Services in Avocado Heights, CA
Concrete driveway building
Many driveways here run past the house to a back garage or barn. We tear out the cracked slab, regrade it to drain and pour new.
Slab foundation building
Horse properties often need a barn, tack room or workshop on a level floor. We pour the slab foundation on a dug-out, packed base.
Concrete patio construction
Backyards here often have room for a big patio on flat ground. We pour it with a slight fall away from the house so rain runs off.
Concrete sidewalk building
Deep lots mean long walkways from the gate to the house and out back. We replace cracked, uneven runs and pack the base under them first.
Concrete steps construction
Front steps on the older houses here often settle, chip or pull away from the porch. We break them out and pour new concrete steps that rise evenly.
Concrete parking lot building
Small property owners here call us for lots behind shops and rentals that see daily trucks. We pour them reinforced and sloped to drain.
Avocado Heights, CA properties and local conditions
The ground in Avocado Heights is mostly flat, which sounds easy until it rains and the water has nowhere to go. A flat slab holds puddles, and a slab that tips the wrong way sends water toward your house or garage. So before we set a single form, I check where the water runs now and where it should end up, then we build the slab to fall away from the house toward the street, a drain or the yard. You won't feel that fall standing on it, but you'll see it work the first time it rains.
A lot of driveways here carry more than a car, with work trucks, horse trailers and the odd camper parked to one side. That weight is why I care more about the subgrade, the dirt the slab sits on, than about the finish on top. We dig out soft soil, pack in base rock and add rebar, steel bars set inside the slab to hold it together, where the load calls for it. A nicer surface can come later, but the base can't, so it's the last place I'd cut to save money.
What it takes to work in Avocado Heights
Avocado Heights isn't a city, so there's no city hall in the picture. The County of Los Angeles is the local government, and LA County Public Works issues the building permits. When your job needs one, we pull it and line up the inspections, and if the county wants a soils report or an engineer's plans first, I tell you at the start and help you get them, because that paperwork sets the start date more than the pour does. We're fully licensed and insured, and before you hire anyone, check that the contractor holds a license from the Contractors State License Board, the state board that licenses builders. A business located in unincorporated LA County also needs a County Business License if its work is on the county's list. Your price moves with the size of the slab, how much digging and base the ground needs, whether old concrete comes out first, and the finish, where a broom finish, the brushed texture that keeps feet and tires from slipping, costs less than stamped work.
We come over from El Monte, on the far side of the 605 and the San Gabriel River. What slows a pour here is usually access on the lot itself: a long driveway, a gate too narrow for the truck, or a slab out back that means pumping the concrete instead of pouring straight from the chute. I check that on the first visit, because it changes both the price and how the day runs. We do the same kind of work next door in West Puente Valley and across the river in South El Monte.

(626) 416-2123What happens after you call us about a job in Avocado Heights
Call and set a visit
You call (626) 416-2123 or send the form, and I call you back to set a time to see the place. Pick a time you can be there, because I want to walk it with you.
Walk the job together
I look at the ground, where the water goes and what you'll put on the slab, and I ask what it's for. You get a written estimate that says what's in the price and what isn't, so you know the cost before you decide anything.
Line up permits and reports
Once you say go, we file for any county permit the job needs and order any report the county asks for. We book the pour around that paperwork, not ahead of it.
Pour, cure and walk through
Our own crew, led by a crew lead, does the work with me on site, and we pour early in the day so the top doesn't dry out before it's finished. When it's done we walk it with you and tell you how long curing, the time the concrete needs to harden, will take before you walk or drive on it.
Frequently asked questions
Is Avocado Heights its own city or part of LA County?
Avocado Heights isn't its own city. It's an unincorporated community in the East San Gabriel Valley, and LA County is its local government, so county rules apply to your concrete job, not the rules of the City of Industry next door.
How do I find out which office issues permits for my address in Avocado Heights?
Put your street address or parcel number into the county's permit site, and it shows which office gives permits for that property. That's worth a minute if you live near the City of Industry line. When the county handles it, the result names the local Building and Safety office, and we take it from there.
Which small concrete jobs need no permit in Avocado Heights?
The county exempts some small work, like fill dirt that holds up no structure and blocks no drainage, within limits such as fill under a foot deep on fairly flat natural ground. That doesn't settle whether your driveway, patio or walkway needs a permit, so I check each job with the county before we price it. Exempt work still has to follow zoning, and separate plumbing or electrical permits can still apply if the job includes them.
How much can a contractor ask up front for a concrete job in California?
On a home improvement job, the Contractors State License Board caps the down payment at $1,000 or 10 percent of the contract price, whichever is less. Every other payment has to be listed in the contract and tied to work done or materials delivered.
How much does a new concrete driveway cost in Avocado Heights?
I can't give you a fair number without seeing the lot, because the price here turns on how far the driveway runs and what it has to carry. A driveway that takes a horse trailer needs more digging, more base rock and more steel than one built for a car. Tearing out the old slab, any permit or soils report, and a stamped finish all add to it, and I write each of those into the estimate so you can see where the money goes.
What causes a concrete driveway to crack, and will a new one crack too?
Most driveway cracks start with a base that settles, water working under the slab, or joints cut late or skipped. A new slab can still get fine cracks, because concrete shrinks as it hardens, so we cut control joints, straight grooves that give it a place to crack, while it's fresh. Those cracks then land in a line we chose instead of across the middle, and the packed base is what keeps the slab from sinking.
About Avocado Heights, CA
Avocado Heights sits between the City of Industry to the north and east, Hacienda Heights to the south, and the 605 and the San Gabriel River to the west. It's mostly houses on flat ground, with an equestrian district that allows more horses than most of the county, so plenty of lots have stalls, arenas and trailer parking out back. You'll see riders on the decomposed granite trail that runs past homes, schools and parks, and at the arena in Avocado Heights Park.
Coming over from El Monte, what we notice most here is how hard the lots get used. Trailers, hooves and work trucks are tough on concrete, and flat ground gives water no help running off, so most of the work on a job here goes into the base and the grade before anything gets finished.
