Clayton homes and yards near Mount Diablo
Clayton sits close to Mount Diablo, and the calls we get from there are mostly from homeowners. We see driveways that have dropped at the garage, back patios people want bigger or flatter, and front walks and steps that have started to tip. That's flatwork, the slabs you walk, park and sit on, and it's the same work our crew does next door in Concord and over in Walnut Creek.
Plenty of yards here have some fall to them, so before we talk about finishes we look at which way your water runs and what the new slab will sit on.

Concrete services for Clayton homes and businesses
Concrete driveway building
When a Clayton driveway has sunk at the garage or cracked through, we tear it out, rebuild the base and pour a new slab.
Concrete patio construction
We pour back patios that fall away from the house so rain runs into the yard, sized for the table and chairs you actually plan to put out.
Stamped concrete services
Stamped concrete pressed with a stone or brick pattern suits a Clayton front entry or patio, and we still grade and base it like any other slab.
Concrete sidewalk building
A front walk that has heaved or tipped is a trip waiting to happen, so we take out the bad sections and pour new ones that line up.
Garage floor concrete
If your garage slab is cracked, stained or sitting lower than the driveway, we can break it out and pour a new floor that meets the driveway flush.
Decorative concrete
Color, exposed stone and borders let a Clayton patio or path match the house, and we talk through upkeep before you pick, since some finishes need resealing.
Concrete retaining walls
On a sloped lot, a concrete retaining wall holds back the hill so you can get a flat spot for a patio or yard.
Concrete floor installation
For a shop, shed or room addition behind a Clayton house, we pour an interior slab that's flat and level enough to build on or finish over.
Concrete pool decks
Around a pool, we slope the deck away from the water and give it a texture that stays grippy for bare, wet feet.
Concrete steps construction
Front steps that have settled away from the porch or rock underfoot, we tear out and re-form with even step heights so nobody catches a toe.
Slab foundation building
For a new garage, workshop or addition, we pour the slab the building sits on, set to the plans your builder or engineer gives us.
Foundation installation
When a Clayton project needs a full foundation rather than a slab, we dig, form and pour it to the plans before framing starts.
Concrete parking lot building
For a small business lot, we build a parking area with a packed base and enough fall to drain, so it holds up to cars turning all day.
Concrete footings
Decks, patio covers and garden walls all need footings, the concrete pads or trenches that carry the weight down into firm ground, and we dig and pour them.
Foundation raising
If a slab or foundation has dropped and doors stick or cracks are opening up, we look at what's sinking and talk through lifting it back.
Concrete cutting
We saw-cut out a broken section of driveway or walk, or open a slab for a new drain line, with clean straight edges so the patch looks planned.

What we check before pouring concrete in Clayton
Clayton is an incorporated city in Contra Costa County, so before we start we check with the city or county 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, and that check comes before we set a pour date. Contractors here are licensed by the state through the Contractors State License Board, the same as anywhere in California, so ask anyone you're thinking of hiring for their state license before you sign. We're licensed and fully insured.
What moves the price is how much old concrete comes out, how much digging and base the ground needs, how close the truck can get and the finish you pick. The schedule turns on that permit check, the weather on pour day and curing, the days fresh concrete needs to harden before it can take weight. I don't quote concrete off a phone call, so you get a written price after I've walked and measured the job. We work the same way here as we do out in Discovery Bay or back home in Antioch.

Why Clayton driveways and patios sink and pool water
Most sunken, cracked driveways and patios we get called about failed from underneath, because the subgrade, the dirt the slab sits on, was raked level instead of dug out and packed, so it settled and took the concrete with it. On a lot with any slope, water running under the slab speeds that up. If you've got a budget to stretch, I'd rather cut back on the fancy finish than on the base, because you can redo a surface later but you can't fix the ground once concrete is on it.
The other thing we see is water pooling against the house from a patio or walk that was poured falling toward the wall. We set the grade so water runs off toward the yard or the street before a single form goes in.
How a concrete job in Clayton runs from start to finish
Here's how a job goes from your side, from the first call to standing on the finished slab with me.
Call us or send the form
Tell us roughly what you want poured and where, and we get back to you to set a time for me to come by. It helps if you're home for the visit so we can talk it over on the spot.
I walk and measure it
I come out myself, look at the ground, what's around it and how we'll get concrete to it, then send you a written estimate. It costs you nothing, so you have a real number in hand before you decide.
We prep, form and pour
Once you say go, we sort out anything the city or county needs, then dig out, pack the base, set forms, pour and finish the slab. Your part is keeping cars and kids off it until I tell you it's ready.
We walk the finished job
I walk the finished job with you before we leave, so you can see the edges, the finish and where the water runs off. My crew clears out the forms and leftover dirt before we go.
Questions about concrete work in Clayton
Call (925) 503-1201I can give you a real number only after I've walked it, because the biggest costs on a Clayton driveway are the ones you can't see from the street. The choices that raise or lower it are yours, though. A driveway that takes heavy trucks may need a thicker slab with rebar, steel bars laid inside that hold cracked pieces together, and a plain broom finish, the light brushed texture that keeps it from getting slick, costs less than stamped or colored concrete. Call (925) 503-1201 and I'll come measure it.
Under California's rules for home improvement work, a contractor's down payment can be no more than $1,000 or 10 percent of the total contract price, whichever is less. Any other payments have to be listed clearly in the contract and tied to work already done or materials already delivered to your home.
Look up your address on the State Fire Marshal's fire hazard severity zone map for Clayton, which rates how severe the fire hazard is across the city. The Contra Costa County Fire Protection District's updated maps took effect in July 2025, so if you looked before then, look again. Concrete doesn't burn, which is one reason a patio or walk right up against the house makes sense out here.
You can walk on it a good while before you can drive on it, and I'll tell you the day for each when we pour. Concrete keeps curing well after it looks dry, and a car on it too early can crack a slab that would have been fine with more time.
It will probably crack somewhere, because all concrete does, but it shouldn't crack like the old one. We use control joints, the straight grooves we cut into the slab so it cracks along a line we picked instead of across the middle. Old slabs crack in ugly places when the joints were cut late or skipped, or when the ground under them settled, which is why we cut joints on time and pack the base first.
Often, yes, if the ground under the rest of it is still solid. We saw-cut out the bad section along a clean line and pour a new piece, though new concrete won't match the color of the old exactly. If the whole driveway has sunk, a patch just moves the problem, and I'll tell you that at the estimate.
