Orinda homes and the concrete around them
The Orinda calls we get usually come from homeowners in established neighborhoods, where the driveway, the front steps or a backyard wall has been there for decades and is finally showing it with cracks, a sunken section or water pooling where it shouldn't. Outside the small downtown around Theatre Square it's nearly all houses, many on sloped lots with long driveways and yards that step down the hill.
We do the same work over in Lafayette and down in Danville, but Orinda jobs tend to ask more of the prep. On a sloped lot the subgrade, the ground the slab sits on, has to be dug out and packed hard, and the water has to go somewhere other than toward the house, because a slab only stays flat as long as what's under it does.
Concrete services we offer in Orinda
Concrete driveway building
Long, sloped driveways are common in Orinda, so we build them on a deep, packed base and give them a broom finish, a ridged texture that helps tires grip.
Concrete patio construction
Backyards here often fall away from the house, so a new patio usually means cutting a level spot, packing the base and pitching the slab so water runs off.
Stamped concrete services
Stamped concrete gives a patio, walk or entry the look of stone or brick, which suits Orinda homes where plain gray would look out of place.
Concrete sidewalk building
Front walks on older Orinda lots often heave or sink where roots and runoff got under them, so we rebuild them on a proper base with joints.
Garage floor concrete
Older garages here often have cracked, stained floors that hold water, and a new slab gives you a flat surface that drains toward the door.
Decorative concrete
Colored, exposed-aggregate and other decorative finishes let a driveway, patio or walk match the house, which matters on Orinda streets where every home has its own style.
Concrete retaining walls
Sloped Orinda yards lean on retaining walls to hold back the hill and make usable flat ground, and we build ours with drainage behind the wall.
Concrete floor installation
For basements, workshops and new rooms, we pour interior slabs that come out flat and ready for flooring, with steel set in where the load calls for it.
Concrete pool decks
A pool deck has to shed water away from the pool and the house and feel good underfoot, so we settle on the finish with you before we pour.
Concrete steps construction
Steep front yards in Orinda mean a lot of concrete steps, and we rebuild worn or tilting ones with even risers so nobody catches a toe.
Slab foundation building
For additions, garages and backyard buildings on Orinda lots, we build slab foundations on a packed base with rebar, the steel inside that holds the slab together.
Foundation installation
When a hillside lot needs more than a slab, we build the foundation to the engineer's plans so the structure sits on footings sized for that ground.
Concrete parking lot building
Shared driveways and small business lots around Orinda need thicker concrete that stands up to cars turning, and we grade them so the water runs off.
Concrete footings
Decks, walls, additions and posts on sloped Orinda yards start with footings, the concrete below ground that carries the weight down into firm soil.
Foundation raising
When part of an older Orinda house has settled, I look at why first, then we raise and support the foundation so floors and doors come back toward level.
Concrete cutting
Cutting lets us take out a broken section, open a path for a drain line or cut control joints, the planned grooves where a slab can crack neatly.

Working in Orinda: permits, licenses and what moves the price
The City of Orinda contracts with Contra Costa County for building services, so if your job needs a permit, the county building department issues it and does the inspections. The county only processes it once the other offices sign off, and most permit jobs here also need the city's Planning Department to approve zoning and the Waste Management Plan, the city's rule for recycling job debris, so a permit job waits on two offices before we can pour. The county's list of common permit work is about things like roofs, windows and kitchens, not driveways or patios, so I tell you at the estimate whether your job needs one and we handle the application. Before you hire anyone, check that they hold a license with the Contractors State License Board and have registered with the city, which Orinda requires of nearly every business working here. We're fully licensed and insured.
The price mostly comes down to the size of the slab, how much old concrete we tear out and haul off, how much digging and base the slope needs, whether there's steel or a wall in the job, and how easily the concrete truck can reach the spot. On a steep driveway or a tight street we sometimes need a pump to get the concrete where it goes, which adds cost, and the schedule turns on the permit, if there is one, then on a good day to pour. We're based in Walnut Creek, a short drive west on Highway 24, and your estimate is written out so you can see each part of the job.
Why Orinda driveways and slabs give out
Older neighborhoods here usually got corrugated metal storm drain pipe, which rusts through over time and is expensive to repair. When a drain like that fails near a driveway or a wall, the water soaks the base and the concrete above it sinks or cracks, so I look for drain lines before we pour, and if one is failing I'll tell you to fix it first rather than bury it under new concrete.
The other thing we see is old concrete poured on dirt that was raked level instead of dug out and packed, often with no joints at all. The base is the part you can't see on day one, and it's the first thing people want to cut from a budget, but I'd rather spend your money there than on the finish, because a pretty top on a soft base cracks just like the old one did.
How a concrete job runs when you call us in Orinda
Here's how it goes from your first call to the final walk-through, and the few points where you'll want to be around.
Call or send a message
Call (925) 532-0140 or use the form, and we'll set a time for me to come out. Tell us what you're seeing, like cracks, sinking or pooling water, so I know what to look at.
I walk the site with you
I check where the water runs, how the old concrete failed and how you'll use the new slab, so it helps if you're home for this one. You get a written estimate with each part broken out, so you can see where the money goes before you decide anything.
Permits get lined up first
If a permit, an engineer or a designer is part of the job, we get that sorted before we put you on the calendar. On a permit job in Orinda, the start date waits on those approvals.
We pour, then walk it together
My crew and I dig out, pack the base, pour, finish and cut the joints, and you don't need to be home for most of it. When it's done we walk it with you and go over curing, the wait while the concrete gains strength before it takes weight.
Questions about concrete work in Orinda
How much does a new concrete driveway cost in Orinda?
There's no honest single number, because the price turns on things I can only measure on site, mostly the size, the tear-out, the slope and how the truck gets in. If you need to save money, trim the finish and keep the base, since plain concrete on a dug-out, packed base outlasts a fancy top on raked dirt. The written estimate shows each part so you can choose where to cut.
Do I need a permit to build a retaining wall in Orinda?
Yes, a retaining wall over 3 feet tall in Orinda needs a building permit. The city also limits walls to 4 feet within 10 feet of a property line or inside the required yard setback, whichever is greater, and to 8 feet elsewhere. A bigger grade change usually means two shorter walls stepped up the slope, and I'll lay that out with you at the estimate.
Do I need a permit to replace the driveway apron or sidewalk in front of my Orinda house?
Any work in the public right-of-way in Orinda needs an Encroachment Permit from the city's Public Works & Engineering office, and that can include the part of your driveway or walk nearest the street. Whether the rest of the job needs a county permit is something I check for your address, as covered above. If your job needs either one, we handle the application.
What happens to the old concrete when you tear out a driveway in Orinda?
We break it out and haul it away, and broken concrete usually goes to a recycler. On larger projects the city requires it, with at least 65% of the construction and demolition debris going to an approved recycling facility and a hold placed on the permit for it. That applies to residential additions or alterations that affect 1,000 square feet, are valued at $50,000 or more, or add conditioned space, and to demolitions that need a demolition permit.
How long until I can drive on a new concrete driveway in Orinda?
Longer than it takes before you can walk on it, because concrete keeps curing and gaining strength well after it feels hard. The mix, the thickness and the weather all change the timing, so I give you the dates for your pour when we finish rather than a number up front.
What causes concrete driveways to crack in Orinda?
Most cracks come from what's under and around the slab, not the concrete itself: a base that was raked instead of packed, water running underneath, or joints cut late or skipped. A failing old drain line, as mentioned above, does the same thing. No slab is crack-proof, which is why we cut control joints on time, so any cracking happens where we chose and not across the middle.
