Services in Lafayette, CA
Concrete driveway building
Long, sloped driveways here settle and crack when the base under them wasn't packed. We dig out to firm ground, pack the base and pitch it to drain.
Concrete retaining walls
Sloped yards here often need a wall to hold soil back above a drive. We set it on solid footings with drainage behind it.
Concrete steps construction
Houses above the street often have steps that heave and tip with age. We pour new ones with even step heights and a slight fall to shed water.
Concrete pool decks
Pools on graded hillside lots often sit beside a deck that's sunk on the low side. Our concrete pool decks start with a packed base and drain away.
Concrete patio construction
Patios here are often squeezed onto the flat spot behind the house, where water pools against the wall. We slope ours toward the yard instead.
Concrete footings
Decks, walls and additions on sloped ground need footings dug into firm soil, not loose fill. We dig, set the steel and pour to your plans.
Lafayette, CA properties and local conditions
Most of the concrete we pour in Lafayette goes on sloped ground. On a hillside lot the subgrade, the soil the slab actually sits on, is often part cut into the hill and part filled in, and the filled side settles if nobody digs it out and packs it, which is why so many older driveways here crack along the low edge. We dig past the loose fill, pack a base you could park a tractor on, and set the fall of every slab so water heads off the drive and away from your house instead of running underneath it.
Big trees are the other thing we plan around, because their roots lift old walks and drives at the edges. If a tree near the work is protected, the City requires a Tree Permit before it can come out, so we lay the slab out around the roots rather than count on losing the tree.
What it takes to get a concrete job done in Lafayette
Lafayette's building permits and inspections run through Contra Costa County, which the city contracts with, but the City's own Planning department does a zoning plan check first, before the county reviews anything. That means a job needing a permit clears two desks before we dig, so we start the paperwork once you've okayed the estimate, pull the permit as your contractor and handle the inspection calls for our part. You'll want to see your contractor's state licence, which the questions below cover, but don't bother asking about a City business licence, because Lafayette doesn't require one as long as the business follows the zoning rules.
Price here mostly moves with how much old concrete comes out and gets hauled, how much digging the base takes on a slope, how close the truck can get, and the finish you pick, and the schedule turns on permit review and the curing wait after the pour. Your written estimate spells out what's included, like whether hauling the old slab away is part of it. We come over the hill from Orinda on Highway 24, and we do the same driveway, wall and step work in Moraga and over in Piedmont, so steep, tight lots like the ones here are familiar ground for our crew.

Call or send the form
Call (925) 257-6590 or use the form and tell us what you're thinking about. We pick a time for me to come out to your house.
Walk the job together
I look at the ground, where the water runs, the trees and anything in the way, and ask what the concrete has to carry or hold back. You get a written estimate that says what's included, so you see the number before anything gets booked.
Line up permits and marking
Once you're ready, we line up any permits and get the utilities marked before we dig. If your job goes through the plan check and county review, that sets our start.
Prep, pour and walk it
Our crew lead and finishers dig and pack the base, form, pour and finish, and I'm usually there on pour day. I walk the finished work with you before we pack up and tell you when it's ready for feet and for cars.
Frequently asked questions
Do I need a permit to pour a concrete driveway in Lafayette?
Plan on checking, because the county that runs Lafayette's building permits says almost all projects need one, and its permit information page asks owners to contact its staff about any additional permits. Work at the street end of a driveway, or materials stored in the strip along the road that the City controls, also needs a City Encroachment Permit. We check your job with the right office before we start rather than guess.
How much does a concrete driveway cost in Lafayette, CA?
It comes down to the tear-out, the base work, the slope and access, and the finish, so I give you a written number after walking your lot. A broom finish, the light brushed texture that gives tires and shoes some grip, costs less than stamped or colored work, and rebar, the steel inside that holds the slab together if it cracks, adds a little but earns its keep on a driveway. If the budget's tight, cut the fancy finish and keep the base, because nobody sees the base on pour day and it's what decides whether the slab settles.
When does a contractor need a state license in California?
A contractor needs a state license whenever the job needs a building permit, uses hired workers, or runs $1,000 or more in labor and materials. Even a small job under $1,000 needs one if it takes a permit or a crew, so that covers about any driveway or patio. We're licensed and fully insured, and you can look up any contractor with the Contractors State License Board before you sign.
How do I find out if my Lafayette home is in a fire hazard zone?
Look your house up on the City's Fire Hazard Severity Zone Map, because your zone depends on exactly where your house sits on it. The map rates parts of the city Moderate, High and Very High. Concrete doesn't burn, so a patio or walk against the house won't add fuel, and it's worth knowing your zone before you plan the yard around the house.
How long will I be without my driveway in Lafayette?
You're usually without it for the tear-out, base work and pour, plus the curing time, the wait while the concrete gains strength before it can take weight. Feet come back before cars do, and on a long driveway we can sometimes pour in sections so you're not cut off from the street the whole time. I walk the finished work with you and tell you when it's ready to drive on.
What causes concrete driveways to crack on Lafayette hillsides?
Most cracks we see come from a base that was raked level instead of dug out and packed, water running toward or under the slab, and control joints cut late or skipped. Concrete cracks a little no matter who pours it, so we cut control joints, shallow grooves that give it a straight line to crack along, and set the slope so water runs away from your house. A packed base and good drainage are what keep a slab from sinking with the dirt under it.
About Lafayette, CA
Lafayette sits between Orinda and Walnut Creek along Highway 24, with a small downtown, quiet neighborhoods like Burton Valley, and homes tucked up into the hills on winding roads. Most of what we work on is single-family houses, plenty of them older, with yards that step up or down from the street and driveways that climb to the garage.
That ground shapes the job more than anything. Flatwork, our word for driveways, patios and walks, rarely stands alone here, because a new drive often needs a wall to hold the bank and steps up to the front door, so I look at the whole slope on the walk-through, not just the slab.
