Lafayette homes, lots and the concrete around them
Lafayette is mostly homes, from the streets around downtown out to Burton Valley, with shops and offices through the middle of town and a lot of yard around everything else. When we're here, it's usually for a driveway that's cracked and sunk, a patio that tips toward the house, front steps pulling away or a wall holding up a hillside garden. It's a short drive out Highway 24 from Walnut Creek, CA, where we're based as a concrete contractor, so Lafayette jobs get the same crew and the same prep as the ones close to home.
Plenty of these houses have been standing for decades, and many sit on lots that slope, with big trees close to the drive. That means more digging and grading before a pour, careful work around roots, and real attention to where the water goes once the new slab is in.
Concrete work we do for Lafayette homes
Concrete driveway building
Plenty of Lafayette driveways climb up to the garage, so we dig out the old base, pack new rock and pitch the slab so water runs off.
Concrete patio construction
A backyard patio here often sits on uneven ground, so we cut and pack the subgrade, what the slab sits on, before we set forms.
Stamped concrete services
Stamped concrete gives a patio or front walk the pattern of stone or brick, which suits the mix of older houses and remodels we see in Lafayette.
Concrete sidewalk building
Lafayette's yard trees often heave front walks into trip edges, so we replace the lifted sections and slope the new walk so water runs off instead of pooling.
Garage floor concrete
When an older Lafayette garage slab is cracked or sunken, we break it out, rebuild the base and pour a new floor that drains toward the door.
Decorative concrete
Color, exposed stone or a sandblasted finish lets a Lafayette entry or patio match the house, but we build the base first, since no finish fixes a bad one.
Concrete retaining walls
On sloped Lafayette lots, a concrete retaining wall holds back the hill for usable flat ground, with drainage behind it so water doesn't build up.
Concrete floor installation
For a workshop, studio or new room in a Lafayette remodel, we pour interior slabs over a vapor barrier so ground moisture doesn't come up through the floor.
Concrete pool decks
Plenty of Lafayette backyards have a pool with a cracked old deck, and we replace it with a textured surface sloped away from the pool and the house.
Concrete steps construction
Lafayette homes set above the street often need front steps, and we form each rise the same height, because an uneven step is the one people trip on.
Slab foundation building
For an addition or backyard studio here, we pour slab foundations on a packed base with rebar, steel bars that hold the slab together if it cracks.
Foundation installation
When a remodel or new build here calls for a perimeter foundation, we build it to the engineer's plans and line up inspections before anything is poured.
Concrete parking lot building
For offices, shops and shared lots around downtown Lafayette, we pour parking areas built for daily traffic and graded so water drains off instead of pooling.
Concrete footings
Decks and walls on a sloped lot sit on footings, the concrete that carries their weight into firm ground, so we dig as deep as the plans say.
Foundation raising
If doors stick and floors tilt in an older Lafayette house, I'll tell you straight whether raising and leveling the foundation is worth doing.
Concrete cutting
We saw-cut openings for doors and drain lines, and cut a clean edge around a damaged section so the rest of a Lafayette driveway can stay.

Working in Lafayette: permits, licenses and access
Building permits for Lafayette are handled by Contra Costa County, which does the plan check and inspections for the city, but a permit job usually starts with the city's zoning plan check, so there are two reviews to clear before a pour date is real. The license to ask any contractor about is their state contractor license, because the city's own policy is that businesses don't need a local business license to work here. We're fully licensed and insured, and if your job needs a permit I'll tell you at the estimate and we'll handle the application. Price here turns mostly on how much old concrete and soft ground has to come out, how much the lot slopes and how far the truck sits from the forms, and the schedule turns on whether a permit is part of it. Your written estimate shows each of those parts separately.
A lot of Lafayette jobs come down to access as much as concrete. Streets off the main roads get narrow and curvy, driveways climb, and the truck often can't get close, so we plan where it parks, whether we pump or wheel the concrete in, and how to keep a neighbor's drive clear on pour day. We work the same way just over the hill in Orinda, where the lots raise the same questions.
Why Lafayette driveways and patios crack and settle
A lot of the concrete around older Lafayette houses was poured on dirt that was raked level instead of dug out and packed, so as that dirt settled over the years, the slab went with it. That's where the sunken driveway corner and the patio tipping toward the back door come from, and pouring a thin new layer over the top doesn't fix it. We break out the old slab, dig down to firm ground and pack a new base in layers, which is the part you never see and the first thing a cheaper bid cuts. If the budget is tight, I'd rather keep the base and go with a plainer finish, because a nice surface on a bad base cracks just the same.
On a sloped lot, water runs toward whatever is downhill, and too often that's the house. We check where the water goes before we set a single form and pitch the new slab away from your foundation, and where the hill is too steep for that, a retaining wall or a drain becomes part of the plan.
What happens after you call us about Lafayette concrete
Here's how a job runs from your first call to the final walk-through, so you know who you'll talk to and when the concrete actually goes in.
Call or send the form
Call (925) 532-0140 or use the form and tell me roughly what you want built and where. I answer my own phone, and we set a time for me to come out.
I look at the site
I walk the ground with you, check the slope and where water runs, and ask how you'll use the slab, so it helps if you're home. You get a written estimate with each part of the job listed, removal and base included, so you can see where the money goes.
Permits and plans come first
If the job needs a permit, an engineer or a designer, we get that lined up before we schedule, which in Lafayette means clearing the city and county reviews described above. Once it's approved, we set your pour date.
We build it and walk it
My crew and I dig out, pack the base, set forms, pour and finish, with me on site the whole time. When it's done, we walk it together and I go over when you can start walking and driving on it.
Questions about concrete contractors in Lafayette
How much does a new concrete driveway cost in Lafayette, CA?
The price of a Lafayette driveway comes down to its size, what has to come out first and how hard the site is to reach, so I price each one after seeing it. Tearing out an old slab, hauling away soft dirt, building up a sloped section or adding a retaining wall all add cost, while a broom finish, the light texture that gives tires and shoes grip, costs less than stamping or color. The one thing I won't trim to hit a number is the base, because that's what keeps the new driveway from sinking like the old one.
Do I need a permit for a concrete driveway or patio in Lafayette?
Possibly, and it's worth checking before anyone digs, because the county building office that handles Lafayette's permits says almost all projects need one. Its list names pools and foundation repairs but doesn't name driveways or patios, and the county asks owners to contact its staff about other permits a project may need. I'll tell you at the estimate whether your job looks like it needs a permit, and we handle the application if it does.
How do I know if my concrete contractor needs a state license?
Under the California Contractors State License Board's rules, a contractor needs a state license when the job needs a building permit, uses hired workers, or costs $1,000 or more in labor and materials. Even a job under $1,000 needs a licensed contractor if it needs any kind of permit or anyone is hired to help. Most driveway and patio work lands well inside those lines, so ask any contractor for their state license before you sign.
What causes concrete patios to crack, and will a new one crack too?
Most patio cracks come from a base that settled, joints that were cut late or skipped, or a midday pour in the heat that left a weak, dusty top. Concrete shrinks as it hardens, so some cracking is normal, and control joints, the straight grooves we cut across the slab, give it a place to crack in a clean line instead of wandering across the middle. We pack the base, cut joints on time and pour in the cooler part of the day, which keeps cracks few and where we chose, but nobody can honestly promise a slab that won't crack at all.
How long before I can walk or drive on new concrete?
You can walk on new concrete well before you can drive on it, and I give you both dates on pour day because they depend on the mix and the weather that week. Concrete keeps curing, slowly hardening and gaining strength, long after it looks dry, and a car or a moving truck on it too early can crack a slab that would otherwise have been fine. If it's your driveway, plan on parking on the street for a while, and keep heavy trucks off it longer than your car.
Do I need a city permit to work near the street or a creek in Lafayette?
Often, yes, because the city requires an encroachment permit for work or for storing materials and equipment in its right-of-way, which on most residential streets reaches a good way in from the middle of the road. That means the bottom of a driveway or a rock pile by the curb can fall inside it. Owners along a creek need a creek setback determination before work, and taking out a protected tree takes a tree permit, so I'll flag any of those at the estimate.

Calling before you settle on a finish lets me check the ground under your old slab first, and that's the part that decides how long the new one lasts.
