Lafayette's hills and what they mean for concrete
Lafayette runs along Highway 24 just west of Walnut Creek, where we're based as a concrete contractor, and right beside Pleasant Hill. It has a small downtown, and its quiet residential streets climb into the hills from Burton Valley out toward the reservoir. Most of our calls here come from homeowners on single-family lots with mature trees, long driveways and backyards built around the land instead of flattened.
Plenty of these houses have been through a few owners, so we often find several rounds of concrete on one lot: an original walk, a patio added later and a driveway somebody widened. That mix, and the hills under it, is why we spend more of our time here on the base, the drainage and how new concrete meets old than on the finish.
Working in Lafayette: permits, licenses and access
Building permits in Lafayette come from Contra Costa County, because the city contracts with the county's building inspection department for plan review and inspections. When a job needs a permit, the city's building permit process starts with an online zoning plan check by its planning department, with a full set of plans, and the county's review comes after that, so on a permitted job the paperwork usually sets the start date more than the pour does. The city doesn't require business licenses at all, so the license to check on any contractor is the state one. We figure out early whether your job needs a city or county sign-off, and when it does, we can handle the application and paperwork for you.
Price here usually turns on the ground: how steep the lot is, how much old concrete comes out, how much base we dig out and pack, whether a wall or a drain has to go in first, and how close a concrete truck can get on a narrow hill street. The schedule turns on permits and access, and the written estimate I put together spells out what's in your price. The streets and lots look a lot like what we work on next door in Orinda, where long driveways climb from winding roads, so we plan each pour around where the truck can park and how far the concrete has to travel.
What do Lafayette driveways and yards need most?
A lot of what we see here starts with a slope. A driveway that climbs from the street sends water down across the concrete, and if nobody checked where it runs, it pools at the low end or washes dirt out from under the edge until the slab starts sinking. Before we set a single form, I work out where the water goes, then we shape the subgrade, the dirt the slab sits on, so the finished slab sheds water away from the house, and on the steep spots we'll talk about steps or a wall instead of fighting the hill.
The other common call is an older patio or walk that's sunk and cracked, usually because it was poured on dirt raked level instead of dug out and packed, sometimes with a big tree's roots lifting one corner. We take it out, pack a proper base and cut control joints, grooves that give the slab a planned place to crack, on time so any cracking lands where we chose.

Concrete work we do in Lafayette
Concrete driveway building
Sloped driveways here carry cars up and water down. We dig out and pack the base, then add rebar, steel that holds the slab together if it cracks.
Concrete retaining walls
Hillside backyards often need a wall before a patio fits. We build ours with drainage behind, because trapped water is what pushes a wall over.
Concrete patio construction
A flat patio on a sloping yard takes grading, sometimes a step. We set the fall so water runs toward the yard, not your back door.
Concrete pool decks
Pools here often sit in sloped backyards. Our concrete pool decks get a grippy finish for bare feet and a slope that sends splash water to drains.
Concrete steps construction
Houses above the street often need steps up to the door. We form every step the same height, because the one odd step is where people trip.
Concrete cutting
On older lots here, adding a drain or widening a walk often means cutting an old slab. We saw clean, straight lines so new concrete meets old neatly.
How it works when you call us in Lafayette
Call or send the form
Call (925) 448-9528 or use the form, and I'm usually the one who calls you back. We set a time for me to come see the site.
I walk the site myself
I look at the slope, the old concrete and where the water goes, and I ask a lot of questions about what you have in mind. Then you get a written estimate that spells out what's in the price, so nothing about the cost is a guess.
Sort out permits and marking
Once you're ready, we take care of the paperwork and any permits your job needs. We also get underground lines marked or scanned before anyone digs.
Prep, pour and walk through
Our own crew digs out and packs the base, pours and finishes, and I'm on site for the parts that matter most. At the end I walk the job with you and go over curing, the wait while the concrete gains strength before you use it, and how to look after it.

Questions about concrete work in Lafayette
How much does a new concrete driveway cost in Lafayette?
Your price comes down mostly to the size of the slab, how steep the lot is and how much old concrete has to come out first. Truck access on a narrow hill street, extra base work, a wall or drain, a stamped or colored surface and any work near the street add to it, while a plain broom finish, a light texture that gives tires and shoes grip, keeps it down. If the budget's tight, I'd rather you go plainer on the surface than cut the base, because the base is the part you can't fix later without tearing it all out.
Do I need a permit to pour a concrete patio or driveway in Lafayette?
Don't assume you don't, because the county says almost all projects need a building permit, and its list names pools and foundation repairs outright. A plain patio or driveway isn't named on that list, and the county asks owners to contact its staff about other permits, so we check with them early, before your schedule is set.
Do I need a city permit for concrete work near the street in Lafayette?
Yes, if any of the work, or even the materials and equipment we stage, sits in the city's right-of-way, you need an encroachment permit from the city. On most residential streets that strip reaches farther back from the road than people expect, and much farther on the main roads, so a driveway apron, the part where your driveway meets the street, often lands inside it. I look at that during the estimate so the permit is in hand before the forms go down.
Do I need a permit to pour concrete near a protected tree or a creek in Lafayette?
If the job means removing or destroying a protected tree, yes, the city requires a tree permit, and if your property sits by a creek, you need a creek setback determination before planning work there. Both can come up on a patio or driveway when a big root is in the way or the yard runs down to the water, so I ask about trees and creeks on the first visit rather than after the dig starts.
How do I check if a concrete contractor is licensed in California?
Look them up on the Contractors State License Board website, because the state license is the one that counts for this work. The board requires one whenever a job needs a building permit, uses hired workers, or costs $1,000 or more in labor and materials, and smaller jobs still need one if a permit or hired workers are involved. We're licensed and insured, and we're glad to have you check.
How do I find out if my Lafayette home is in a fire hazard zone?
Check the city's fire hazard severity zone map, because your zone depends on exactly where your house sits on it. Most of the zoned land in the city is rated High, with smaller areas rated Moderate and Very High. Concrete doesn't burn, which is one reason people ask us about concrete patios, walks and steps close to the house.
