Brentwood homes, lots and the ground under them
Brentwood is a short drive from our base in Antioch, and most of the calls we get here come from neighborhoods with wide lots, long driveways and big backyards. Most of our Brentwood work is flatwork like driveways, patios, walks and steps. People want a parking pad beside the garage, a patio that reaches out toward the back fence, a walk down the side yard or a tired pool deck redone. We do the same work next door in Oakley and out in Discovery Bay.
Big lots mean big slabs, and a big slab moves with whatever is under it. A lot of the ground we dig into around here is clay that swells when it's wet and shrinks when it dries, so we dig out the soft soil, bring in base rock and pack the subgrade, the ground the slab sits on, before any forms go up.
Concrete services we pour in Brentwood
Concrete driveway building
Long Brentwood driveways and extra pads beside the garage get a dug-out, packed base and rebar, the steel bars that hold the slab together under cars and trucks.
Concrete patio construction
Wide backyards here have room for a real patio, and we slope it away from the house so sprinkler water and winter rain run off into the yard.
Stamped concrete services
Stamped concrete gives a Brentwood patio or front entry the look of stone or brick in one poured slab, with the color and pattern picked before we pour.
Concrete sidewalk building
Side-yard walks and paths out to the garden or trash cans, set on a packed base and cut with joints so any cracks land in straight lines.
Garage floor concrete
A cracked or sunken garage floor in an older Brentwood house can come out and go back in level, sloped toward the door so water runs out.
Decorative concrete
Color, exposed aggregate or a custom border around the patio or front walk, for homeowners who want the concrete to match the house and the landscaping.
Concrete retaining walls
Where a backyard steps up or down, a concrete retaining wall holds the soil back and gives you flat ground for a patio, lawn or garden beds.
Concrete floor installation
Interior slabs for shops, sheds and added rooms, poured over a packed base and a vapor barrier so ground moisture doesn't come up through the floor.
Concrete pool decks
Pool decks here take full summer sun and wet feet, so we give them a broom finish, a lightly brushed texture that grips, and slope them to drain.
Concrete steps construction
Front porch steps and the steps off a back door, formed so each rise is the same height and finished with a texture that isn't slick when wet.
Slab foundation building
Slabs for a new garage, workshop or backyard building on a Brentwood lot, with the ground dug out and packed so the building has a firm base.
Foundation installation
Foundations for additions and outbuildings, laid out to the plans and set on ground we've checked and prepared, because that ground carries everything built above it.
Concrete parking lot building
Parking areas for small shops and offices around Brentwood, graded so rain runs to the drains and laid out with joints that handle daily traffic.
Concrete footings
Footings for patio covers, fences, decks and walls, dug to the depth the plans call for so the weight above sits on solid concrete.
Foundation raising
When a slab or part of a house has sunk on shifting clay ground, we find out why it moved and raise it back toward level.
Concrete cutting
Saw-cutting old slabs to make room for a wider driveway, a new walk, a utility line or a door, with clean straight edges and less mess.

Working in Brentwood, from permits to price
Before we pour in Brentwood, we check with the city or county office that handles your address, and if a permit is needed, we apply for it as your contractor or help you file it yourself if you'd rather. That check comes before any forms go up, so it can set the start date. The City of Brentwood issues business licenses, and its application asks for the contractor's state license information, so anyone you hire here should be able to show you both. We're licensed and fully insured, and you can ask me for both when I come out.
The price here mostly comes down to size, how much digging and base rock the ground needs, whether old concrete has to be broken out and hauled off, how close the truck can get and the finish you pick. The schedule turns on that permit check, the weather and the cure. Long driveways on wide lots usually have easy truck access, but a backyard patio behind a finished house can mean a pump or wheelbarrows down the side yard, and your written estimate spells out what that does to your number. Over in Walnut Creek the yards tend to be tighter and steeper, so the same job can price differently there.
Why Brentwood driveways and patios crack and sink
Summers here are hot, and at nearby Round Valley Regional Preserve, temperatures commonly go past 100 degrees in the summer months. Concrete poured in that kind of heat dries out on top before it's finished, which leaves a weak, dusty surface that chips later. In the hot months we start pours early in the morning, have the crew ready before the truck shows up, and keep the slab damp while it cures, which is the slow stretch when concrete hardens and gains strength.
Concrete cracks, and I'd rather tell you that now than after the pour. Big slabs on that clay ground move, so we cut control joints, straight grooves that give the slab a place to crack, early enough that cracks usually land in those lines and not across the middle. If the budget is tight, I'd cut back on a fancy finish before I'd cut the base, because nobody sees the base on day one and it's the part you can't fix later.
How a Brentwood concrete job runs, start to finish
Here's how a job goes from your first call or message to the day I walk the finished slab with you.
Call or send a message
Call (925) 503-1201 or use the form, tell us what you want poured, and we'll set a time for me to come out. It helps if you can be there, so we can walk the layout together.
I measure and look around
I come out myself, measure, check how the ground sits and where water runs, and work out how we'll get the truck or a pump to the pour. Then I send a written estimate, so you see the full price before you decide anything.
We prep, form and pour
Once you say go, we handle anything the city or county needs, dig out and pack the base, set forms and pour, starting early on hot days. My crew and I do the work ourselves.
We walk the job together
I walk the finished job with you before we leave and tell you how long to keep feet and cars off it. Satisfaction guaranteed.
Questions about concrete work in Brentwood
Call (925) 503-1201Yes, for almost any driveway or patio job. The California Contractors State License Board requires a license for anyone building or altering a structure when the job needs a building permit, uses employees, or totals $1,000 or more in labor, materials and everything else, and the contractor has to be licensed before bidding. A bigger job can't be split into smaller pieces to stay under $1,000, so ask for the license before you take a bid.
Under state rules, a down payment on a home improvement job can be no more than $1,000 or 10 percent of the contract price, whichever is less. The state contractors board says any other payments have to be listed in the contract and based on work completed or materials delivered to your home, and the board applies these rules to all home improvement projects.
The California Building Standards Code, known as Title 24, applies to construction across the state. On top of it come state agency amendments and any ordinances the local government adopts, which is one reason we check with the office that handles your address before we start.
Search your address on FEMA's flood map viewer, which FEMA calls the best place to start for official flood hazard determinations. Whatever the map shows, I still look at where water runs on your lot when I come out, because that decides how we slope the slab.
Your price comes from the size of the slab, how thick it needs to be, how much digging and base the ground needs, whether old concrete has to come out and the finish you choose. Long driveways and extra pads on Brentwood's wide lots add up fast, a driveway that carries trucks or an RV usually gets a thicker slab with more rebar, and stamping or color costs more than a plain broom finish. I measure on site and send a written price, because I don't quote concrete off a phone call.
You wait longer to drive on a new driveway than to walk on it, because concrete keeps gaining strength for days after the pour and a car is much harder on it than footsteps. Summer heat, the thickness and the mix all change the wait, so I give you the timing for your slab when we walk the finished job.
