Concrete Contractor in Del Aire, CA - Driveways and Patios Built on a Packed Base
Keystone Beverly Hills Concrete is a concrete contractor based in Beverly Hills. In Del Aire we replace cracked and sunken driveways and pour patios, walkways, steps, garage floors and foundations for homeowners.

Concrete work for Del Aire homes
Del Aire isn't a city of its own. It's an unincorporated part of Los Angeles County, so the county acts as its local government, and that's who we deal with on the permit side. More homes here are owned than rented, so most calls come from people fixing a place they plan to stay in, like a cracked driveway, a back patio that holds water or front steps pulling away from the house. We do the same work nearby in Lennox and Hawthorne.
Your price moves with the size of the slab, how much old concrete we break out and haul away, how much base work the ground needs and the finish you pick. The schedule turns on whether the county wants a permit for your job, the weather on pour day and the wait before you can use the new slab. I come out myself to measure and look at the ground, and the written estimate we send afterward spells out what's included. Under a lot of the old driveways we break out here, the concrete went down on dirt that was raked flat instead of dug out and packed, so it settled right along with the dirt, and that's why the base is where most of the work on a new one goes.
Concrete work we do in Del Aire
Most driveways here run straight from the garage to the street. When one cracks or sinks, we break it out, pack a new base and pour again.
In a back yard here, a patio has to shed water away from the house, so we set the slope before the forms go in.
Stamped concrete gives a front walk or patio the look of stone. The pattern goes on before the slab sets, so we add hands to the pour.
We pour walkways from the driveway to the front door and down the side of the house, sloped so rain runs to the yard instead of the foundation.
Older garage floors here are often cracked or stained from years of cars. We break out the old slab, check the ground under it and pour new.
Decorative work means color, exposed stone or sawn patterns in a slab. We'll tell you how each one holds up to Del Aire sun and foot traffic.
A retaining wall holds back soil where one yard sits higher than the next. Most of our effort goes into the footing and the drain behind it.
For a converted garage or a room addition, we pour an interior floor slab with a moisture barrier under it, so the flooring on top stays dry.
A backyard pool deck takes bare feet, splashing water and pool chemicals, so we give it a texture that grips and slope it away from the pool.
Front steps here get used every day, and an uneven one is where people trip. We form each step the same height and tie them into the walk.
A slab foundation for an addition or backyard unit carries the walls, so the ground is packed and the steel set and checked before any concrete arrives.
New foundation work on a house or garage starts with a look at the soil, the old footing and any drawings, and then we form and pour.
Small apartment buildings and shops around here need parking that drains and carries cars all day, so we build it thicker than a driveway, on a deeper base.
Footings are the concrete under a wall, a post or a backyard patio cover. We dig to the depth the plans call for and set the steel first.
If a floor slopes or doors stick, part of the foundation may have settled. We find the cause first, because lifting without fixing it just buys time.
We saw-cut clean openings in old driveways and patios for a new walkway, drain line or utility trench, so the rest of the slab stays intact.
What Del Aire yards and driveways need
I come out myself to look at the job and write the estimate, then run it on site, and I'll walk you through what goes under the slab before we pour.
A base dug out and packed
We dig out soft dirt and pack the subgrade, the ground the slab sits on, because that's what keeps it from sinking.
Water sent away from the house
Before the forms go in, we check where rain runs, so the new slab slopes toward the street instead of your foundation.
Pours planned around the heat
On hot days we pour early, because a slab that dries too fast turns weak and dusty on top.
Joints cut where cracks should go
Control joints are grooves that tell the slab where to crack, so we cut them before it picks its own spot.
Licensed, insured and guaranteed
We're licensed and insured, and the work is backed by our satisfaction guarantee, with me on site while our crew pours.
What Del Aire homeowners ask us
Who issues the permit for concrete work in Del Aire?
Los Angeles County Public Works issues permits for property in unincorporated areas like Del Aire. Its permits cover new construction, alterations, repairs and replacements, along with grading work, and we ask its local office what your driveway or patio needs at your address. We take care of the paperwork when a permit is needed, and if something has to come from you, like drawings or a soils report, we tell you early.
How do I find out if my Del Aire address is unincorporated?
Look up your address in the county's Z-Net tool, which shows whether it sits in an unincorporated area or inside a city, along with its zoning. Your ZIP code alone can't always tell you, and if the address turns out to be inside a city, another office may handle the permit.
How much does a new concrete driveway cost in Del Aire?
The choices that move a driveway's cost most are the finish, the thickness and how much base work the ground needs. A broom finish, the light texture brushed across the top so feet and tires grip, costs less than stamped or colored concrete, while a thicker slab or more steel adds to it. If the budget's tight, I'd spend it on the base and keep the finish plain, because a nice top on a slab that sinks still has to come out.
How long does a new concrete driveway take before I can drive on it?
You can walk on a new driveway well before you can drive on it, because curing, the slow hardening after the pour, has to go on longer before a slab can take a car's weight. I'll give you both days for your slab before we pour, since they shift with the thickness and the weather, so you can plan where the car goes.
What causes concrete driveways in Del Aire to crack and sink?
Sinking usually starts with a base that was raked level instead of dug out and packed, and stray cracks usually start where joints were cut late or never cut. New concrete still cracks a little as it dries, so the aim is cracks in the joints, not across the middle. We set rebar, steel bars inside the slab, where the job calls for it, so if a crack opens the pieces stay together and level.
How much can a contractor ask for as a down payment in California?
In California, a down payment on a home improvement job is capped at $1,000 or 10 percent of the contract price, whichever is less. The state contractors board, which licenses contractors here, says every other payment has to be listed in the contract and tied to work done or materials delivered. It's worth checking any contract against that before you sign.
