Contra Costa Centre homes around the BART station
Contra Costa Centre is the neighborhood around the Pleasant Hill/Contra Costa Centre BART station, tucked between Pleasant Hill and Walnut Creek, with the Iron Horse Regional Trail running close by. The transit village by the station mixes offices, shops and homes, and the residential streets around it are where most of our calls come from. We see driveways that have dropped at the garage, patios that hold water, and front walks and steps that have shifted over the years.
Lots here tend to be snug, with fences, plantings and the neighbor's driveway close by, so we plan the dig-out, the forms and the cleanup around a small work area and keep the mess off the street.
Concrete work we do in Contra Costa Centre
Concrete driveway building
Helps when an older driveway has sunk at the street or cracked across, because we dig out the soft base and pack a new one first.
Concrete patio construction
A good fit for the smaller backyards here, where a patio has to fit around the house and fences and still shed water away from the walls.
Stamped concrete services
For a patio or front walk that should look like stone or brick, stamped concrete gives the pattern in one pour, though it needs resealing now and then.
Concrete sidewalk building
Replaces a front walk that has heaved or broken into trip points, and we slope it so rain runs to the yard instead of the doorstep.
Garage floor concrete
For a garage slab that's cracked, stained or dusting on top, we break it out, fix what's under it and pour a floor that cleans up easily.
Decorative concrete
Colored, pebble-finish or patterned surfaces for entries and patios close to the street, where how the concrete looks matters as much as how it holds up.
Concrete retaining walls
Holds back a sloped yard so the patio or driveway beside it stays put, with drainage behind the wall so water doesn't push against it.
Concrete floor installation
Interior slabs for small property owners' shops and storage rooms, poured flat and level so flooring or shelving sits right on top.
Concrete pool decks
A deck around a backyard pool needs a finish that grips wet feet and slopes toward the drains, not toward the pool or the house.
Concrete steps construction
Rebuilds front or back steps that have pulled away from the house or rocked loose, with even step heights so nobody catches a toe.
Slab foundation building
The slab under a new garage, shed, room addition or backyard cottage, where the base and the steel inside it matter more than anything you'll see.
Foundation installation
The footings and short concrete walls an addition or new building sits on, dug and formed to the approved plans before any framing goes up.
Concrete parking lot building
For small property owners with a lot that's broken up or holding water, we rebuild the base and slope it so rain heads to the drains.
Concrete footings
Poured footings for decks, posts, walls and small structures, sized for the load so what sits on them doesn't lean or settle over the years.
Foundation raising
When a corner of the house has dropped and doors start to stick, we lift that section back toward level and add support underneath.
Concrete cutting
Clean saw cuts through an old slab for a new drain, a door opening or a repair, so we take out only the piece that has to go.

Permits and access on Contra Costa Centre concrete jobs
The first thing I sort out on a job here is who issues the permit, because Contra Costa County handles building permits and inspections for addresses outside city limits and says almost every project there needs one, while an address inside a city goes through that city's own permit department. You can look up which one covers you with the county's CCMAP mapping tool on the county's permit page. We check with that office, handle the permit paperwork when one's needed and plan the start date around the approval, since that's usually what the schedule waits on. Before you hire anyone, ask about two things, a current state contractor license and, for work in the unincorporated county, a county business license, and the questions below cover when each one applies. We're licensed and insured.
Around the BART station and the transit village, streets carry station traffic and houses sit close to their neighbors, so before pour day we work out where the truck parks and how the concrete gets from the curb to the forms. The price moves with that access, the size of the slab, how much old concrete comes out and what the base needs, and the schedule moves with the permit and the curing, the days new concrete needs to harden before you walk or drive on it. Your own figure comes in the written estimate after I've seen the site. It's the same driveway and patio work we do in Clayton and Concord.
Sinking slabs and pooling water on homes here
Most sinking driveways and walks we tear out here failed from underneath. The base, the packed layer the slab sits on, was raked smooth instead of dug out and compacted, so it settled and the concrete cracked and dropped with it. We dig down to firm ground and pack a new base in layers, and if a budget gets tight I'd rather you spend it there than on a fancier surface, because nobody sees the base on day one but it's the one part you can't fix later without breaking out the slab.
The other call we get is a patio or driveway that pools water or tips toward the house, usually because nobody checked where the water would run before the pour. We check the fall of the ground at the estimate and set the forms so the new slab sheds water away from your walls.
How a concrete job runs when you call us in Contra Costa Centre
From the first call to the last walk-through, here's what you'll see from us and who you'll be dealing with at each step.
Call or send the form
Reach us at (925) 536-0945 or through the form, and we'll set a time for me to come out. Tell us roughly what you have in mind and where the trouble is, and a photo helps.
Walk the site together
I come out myself, look at the slab, the base and where the water runs, and explain the choices that change the price. You get the estimate in writing, so you know what you're paying for before you decide anything.
Sort out the permit
We check what your job calls for with the county or city that covers your address and handle the permit paperwork when one's needed. When a permit is involved, the pour date waits on that approval, and I'll keep you posted on where it stands.
Pour, finish and walk through
I'm on site with our small crew of form setters and finishers from the dig-out to the last joint cut. When it's done we walk the finished job together, and I tell you how long to stay off it while it cures.
Questions about concrete work in Contra Costa Centre
Do I need a permit to pour a driveway, patio or retaining wall in Contra Costa Centre?
Plan on needing one for most concrete work, and some jobs carry extra steps. The county requires a building permit for retaining walls past a set height, can ask for drainage plans when a project adds a large area of new paving that rain can't soak through, and sends jobs that dig for a foundation, piers or a retaining wall through a sanitary or environmental health review. I check what your job calls for before the estimate is final, and we handle the permit paperwork when one is needed.
Does a concrete contractor need a California license for a small driveway or patio job?
Almost always, because the state Contractors State License Board requires a license whenever a project needs a building permit, uses employees or costs $1,000 or more. The only way out is a job that needs no permit, uses no employees and comes in under $1,000, and a bigger job can't be split into smaller bills to get under that line. Ask any contractor bidding on your concrete for their state license before you sign.
Does a contractor need a county business license to work in unincorporated Contra Costa County?
Yes, the county requires a business license, which is really an annual tax, from state-licensed contractors who work or are based in its unincorporated area. It runs $100 a year plus $10 per employee, and the contractor includes a copy of their current state license with it. It's fair to ask anyone bidding on your job whether they hold one.
How much does a concrete driveway cost in Contra Costa Centre?
The price of a driveway here comes down to its size and thickness, the old concrete we break out and haul away, the base and the finish you choose. A plain broom finish, a light brushed texture that gives shoes and tires some grip, costs less than stamped or colored concrete, and if the budget is tight that's the place to save, not the base I talked about above. I'll put your own figure in writing after looking at the driveway with you.
What causes a new concrete driveway or patio to crack in Contra Costa Centre?
Concrete shrinks as it hardens, so some cracking is normal, and the real job is deciding where it happens. We cut control joints, straight grooves in the surface, early enough that the slab cracks along those lines instead of across the middle, and we pour on a packed base so it doesn't settle unevenly. Rebar, the steel rods set inside the slab, holds any crack tight so it doesn't spread or step up.
How do I plan a concrete job near the Iron Horse Trail in Contra Costa Centre?
Start by getting buried lines marked, because the county says the Iron Horse Corridor carries underground water lines, gas pipelines and fiber optic lines, along with flood control channels and power lines. We have lines located before anyone digs and keep the dig-out and forms on your property. If your job sits close to the corridor, tell us when you call so I can look at it on the first visit.
