Oakley homes, lots and the ground under them
Oakley sits between Antioch to the west and Brentwood to the south, with the Delta along its north edge. Most of my calls here come from homeowners in newer subdivisions who want a wider driveway, a back patio or a walk down the side yard. The rest come from older places on bigger lots, where the original concrete has settled and cracked over the years.
The ground here is mostly flat, so water doesn't run off on its own the way it does on a hillside lot. On a lot like that, the slope we build into the slab and the base under it decide whether rain drains away or sits against your house.
Concrete work we do for Oakley homes
Concrete driveway building
Many Oakley driveways are too narrow for two cars and a boat trailer. We widen or replace them on a dug-out, packed base so nothing settles.
Concrete patio construction
Flat backyards here hold water after a rain. We pour patios that slope away from the house, so water runs to the yard instead of your back door.
Stamped concrete services
Stamped concrete gives a patio or entry the look of stone or brick. We get the base right first, because a pattern can't hide a sinking slab.
Concrete sidewalk building
Front and side-yard walks on older lots heave or sink once roots and water get under them. We replace the bad sections on a packed base.
Garage floor concrete
Garage floors in older Oakley homes often crack or turn dusty on top. We break out the old slab and pour a new one built to carry cars.
Decorative concrete
Color, exposed aggregate and saw-cut patterns let a plain slab match the stucco and trim on newer Oakley homes. We pick the finish with you before anything is poured.
Concrete retaining walls
Where a yard steps down next to a higher lot, a concrete wall holds the dirt in place. We drain the back side so water doesn't push it over.
Concrete floor installation
Shops, sheds and small commercial spaces around Oakley need an inside floor that's flat and level. We level it carefully so shelving and equipment sit true.
Concrete pool decks
Pool decks here bake in the afternoon sun and stay wet all summer. We give them a textured finish for grip and slope them so water drains off.
Concrete steps construction
Front steps on older homes crack or pull away from the porch as the ground moves. We pour new ones with even step heights and a solid footing.
Slab foundation building
Room additions, backyard units and detached garages usually sit on a slab. We dig, pack and form to the plans so it carries the building it was drawn for.
Foundation installation
When an addition or workshop on one of Oakley's bigger lots needs a full foundation, we lay out, dig and pour it to the engineer's plans.
Concrete parking lot building
Small business owners in Oakley call us for parking areas that drain and hold up under traffic. We build them thicker than a driveway, on a well-packed base.
Concrete footings
Patio covers, fences and walls all start with footings, the concrete underneath that spreads the weight into the ground. We dig them to the depth your plans call for.
Foundation raising
If part of a slab or foundation has dropped, I find out why it sank first. Then we raise it and support it from below.
Concrete cutting
We saw-cut openings for new doors, trenches for pipe and clean edges where old concrete meets new, so a widening doesn't leave a ragged seam.

Working in Oakley: permits, licenses and what sets the price
Building permits in Oakley come from the city's Building Division, and the city says most construction projects need one before work starts, so the permit review is usually the first thing that sets your start date. Before you hire anyone, ask to see two things. One is a state contractor license, which California requires when a job needs a permit, uses employees or runs $1,000 or more in labor and materials, and a bigger job can't be broken into small contracts to get under that line. The other is an Oakley business license, since the city's program covers contractors who come in from outside city limits too. We're licensed and fully insured, and before we start we check with the office that handles your address. If a permit is needed, we apply for it as your contractor, or we help you through it if you'd rather file it yourself.
Oakley is a short run from our base in Antioch, so getting a truck and crew here is no harder than on our jobs farther west in Bay Point. What changes the price from one Oakley job to the next is the size and thickness of the slab, how much old concrete comes out, how much of the ground has to be dug out and rebuilt, and whether the truck can reach the forms or we have to pump into a backyard. The schedule turns on the permit review, the weather and curing, the days fresh concrete needs to gain strength before you use it. Your own figure comes in a written estimate after I measure.
Sinking, pooling and cracking on Oakley lots
Most sinking slabs we tear out here were poured on dirt that was raked level, not dug out and packed. When that step is skipped, the subgrade, the ground the slab sits on, keeps settling for years, and the concrete drops with it, usually at the edges first. A flat lot makes it worse, because water sits under the slab and softens what's left. We dig out the soft material, bring in base rock and pack it in layers, then set the slope so water moves away from the house. That base is the part you never see once it's poured, and it's the first thing people want to cut from the budget. I'd rather you get a plain broom finish, the light texture that gives you grip when it's wet, over a good base than a fancy surface over a bad one.
Summer afternoons here get hot, and that's hard on fresh concrete because the top dries out before the slab underneath, which leaves a weak, dusty surface that chips later. We pour early in the day and keep the slab damp while it cures, so the top wears as well as the rest.
How a concrete job runs when you call us in Oakley
Here's how it goes from your first call or message to the walk-through at the end, and who you'll deal with along the way.
Call us or send the form
Tell us what you have in mind and where the house is, and we'll set a time for me to come out. You don't need plans or measurements yet.
I walk and measure the site
I look at the ground, where the water runs, what's around it and how we'll get concrete to the forms. Then I send a written estimate, so you know the number before anything gets dug.
We handle permits, then pour
Once you say go, we sort out anything the city needs, and the city's permit review has to clear before we can start digging. Then my crew and I dig out, pack the base, set forms, pour and finish.
We walk the finished job
Before we leave, I walk the slab with you and tell you when it's ready for foot traffic and when it's ready for cars. Satisfaction guaranteed.
Questions about concrete work in Oakley
Call (925) 503-1201Ask the city's Building Division, because the city says most construction projects need a permit before work starts, and its list of exempt work doesn't name driveways or patios. The division can tell you whether your project needs plans at 925-625-7005, and zoning rules like driveway width can still apply even when a permit doesn't. Before we start, we check with the city for your address either way.
A wall up to 4 feet tall, measured from the bottom of the footing to the top of the wall, is on the city's exempt list, unless it holds up an added load, like a driveway or a slope above it, or holds back certain soil types the code names. For exempt work, the city says to check with its Planning Division, since setbacks and other zoning rules still apply. If there's any doubt about your wall, we treat it as permit work.
Only the property owner, someone the owner authorizes or a contractor licensed by the state board can get a building permit in Oakley. We apply as your contractor, or we help you through the city's online permit portal if you'd rather file it yourself.
On a home improvement job, the state caps the down payment at $1,000 or 10 percent of the contract price, whichever is less. Any other payments have to be spelled out in the contract and tied to work done or materials delivered. If someone wants more than that before they start, keep looking.
It comes down to how much driveway you need and how much work the ground takes before we pour. Widening an existing driveway usually costs less than tearing out and replacing the whole thing, and a broom finish costs less than stamped or colored concrete. A backyard pour that needs a pump costs more than one the truck can reach. I don't quote concrete off a phone call, so I'll measure and send you a written number.
Concrete cracks mostly because it shrinks as it dries and the ground under it moves, so yes, expect some cracking even on a good job. Control joints, the grooves we cut across the slab, give those cracks a straight line to follow, so we cut them on time instead of letting the slab pick its own spot. Rebar, steel bars set inside the slab, helps hold the pieces together. What you shouldn't see is a slab that drops or splits wide, and that's a base problem, which is why we spend our time there.
