Corte Madera jobs run from bay flats to hillsides
We're based in San Rafael, and Corte Madera is a short drive south, between Larkspur and Mill Valley. Most calls here come from homeowners with a driveway that's cracked across, a patio that's dropped away from the back door or a garage floor that's gone uneven. Builders call too, when they need footings for an addition. It's mostly houses and yards, so most of what we pour is flatwork, the slabs that lie on the ground like driveways, walks and patios.
The ground changes from one street to the next. Hillside lots send rain straight at driveways and garages, and the bayside neighborhoods sit on filled land that has been settling for years, so I look at the dirt and the water before we talk about finishes.
Why Corte Madera slabs need a solid base
- Parts of Mariner Cove and Marina Village sit on filled baylands that have settled up to four feet, depending on mud thickness, leaving some homes with tilted floors.
- A slab moves with what's under it, so we dig out and pack the subgrade, the layer the concrete sits on, and say when ground needs an engineer.
- We check where the water runs before we form anything, because a patio or driveway that falls toward the house sends rain to your foundation.
- Price and schedule here turn on what's under the old slab, how much base work it needs and whether a permit applies, which I'll pin down on site.
Concrete work we do for Corte Madera homes
Concrete driveway building
When a driveway has cracked or sunk, we tear it out, rebuild the base and cut control joints, grooves that tell the slab where to crack.
Concrete patio construction
For a patio that holds puddles or tilts toward the house, we pour a new slab that sheds water, with a broom finish, a light texture for grip.
Stamped concrete services
Stamped concrete gives a patio or entry the look of stone or brick, and it needs the same packed base as plain concrete to stay flat.
Concrete sidewalk building
We replace walks and front paths that have heaved or split into tripping edges, setting them on a packed base so the sections stay level with each other.
Garage floor concrete
A garage floor that's cracked, stained or sloped wrong gets broken out and repoured with rebar, steel bars that hold the slab together if it cracks.
Decorative concrete
Colored and textured finishes suit a front entry or courtyard, and I'll tell you which ones hold up and which only look good the first year.
Concrete retaining walls
On sloped lots, a concrete retaining wall holds back soil that's creeping onto a driveway or patio, and taller walls usually need an engineer's design first.
Concrete floor installation
I set tile for years, so we pour interior floors flat enough for tile, wood or epoxy to go down without fighting a wavy slab.
Concrete pool decks
Around a pool, we slope the deck to carry splash water away from the pool edge and the house, with a textured surface that's less slick underfoot.
Concrete steps construction
Steps that rock, crumble or have uneven risers get rebuilt on a solid base, with every step the same height so you're not catching a toe.
Slab foundation building
For a new garage, studio or addition on a slab, we build to the approved plans and have the base and steel ready for inspection before the pour.
Foundation installation
Builders and owners call us for foundations under new homes and additions poured to plan, with the forms checked for square and level before the truck comes.
Concrete parking lot building
For shared lots at small buildings and condos, we pour concrete thick enough for daily traffic and slope it so rain heads to the drains, not doorways.
Concrete footings
Decks, posts and additions sit on footings, concrete pads that carry the weight down to firm ground, and we dig them to the depth on the plans.
Foundation raising
When a house has settled and the floors slope, I start by finding out why it moved, because lifting it without fixing the cause only buys time.
Concrete cutting
We saw-cut openings for doors, drains and utility lines, and cut out damaged sections cleanly so a repair ties into the old slab without ragged edges.

(628) 234-2042Corte Madera concrete questions we hear most
How do I get a permit for concrete work in Corte Madera?
Permits go through the Town of Corte Madera's Building Division, which reviews applications against state and local codes and inspects building construction. I check with the Building Division whether your job needs one, and when it does, we handle the application and the inspections. Every submittal needs the property owner's approval, so you'll sign off before anything goes in.
How do I find out if my Corte Madera property is in a flood zone?
Corte Madera's Public Works Department can help you check, because part of Corte Madera lies in a mapped flood hazard area. If your property is in it, any new development, or an addition or renovation to an existing structure, needs a Floodplain Development Permit. That's worth knowing before we plan footings or a slab for an addition, so I'll ask about it when I come out.
Does a concrete contractor in Corte Madera need a California license?
Yes, a concrete contractor needs a state license for almost any job in Corte Madera. The state licensing board requires one whenever a project needs a building permit, uses any additional workers or comes to $1,000 or more in labor and materials, and the contractor has to hold it before bidding. We're licensed and insured.
Which building codes apply to concrete plans in Corte Madera?
Plans submitted in Corte Madera have to follow the 2025 California codes, including the building, residential, energy and wildland-urban interface codes. Corte Madera adds its own amendments on energy efficiency and EV charging for certain new and renovation projects. For a foundation or a slab under an addition, those plans are what our work gets built to, and I read them before I price anything.
How do I keep a new concrete driveway from cracking in Corte Madera?
You can't keep concrete from ever cracking, but you can keep it from sinking and decide where it cracks, and that comes down to the base and the joints. Most bad cracks I see started with a base that was raked level instead of dug out and packed, so it settled with the dirt, and on the soft ground near the bay that matters even more. We pack the base, slope the slab away from the house, pour early instead of in midday heat that leaves a weak, dusty top, and cut the control joints on time. Then comes curing, the wait while the concrete gains strength, and you'll walk on it well before you drive on it. If the budget's tight, I'd rather cut the finish than the base, because you can't fix a base later without tearing the slab out.
How much does a new concrete driveway cost in Corte Madera?
The cost of a concrete driveway in Corte Madera comes down mostly to its size, what it takes to break out and haul away the old one, and how much base work the ground needs. A steep or tight approach, steel reinforcing, a stamped or colored finish and a permit, if your job needs one, all push it up, while a plain broom finish on firm ground keeps it down. I'll give you a number after I've measured and looked at the ground.
