Corte Madera homes from the hillsides to the bay
Corte Madera fits a lot of different ground into a small city. Older homes sit along sloped streets toward the hills, newer houses and townhomes fill the flatter land near the bay, and shops and offices line the busier roads, so one week we're rebuilding a steep front walk and the next we're pouring a patio on soft, flat ground. Most of what we pour here is flatwork, the driveways, patios, walks and garage floors that lie flat on the ground, along with steps, walls and foundations for additions.
We do the same work next door in Larkspur and as far north as Windsor, and what holds true everywhere is that the ground decides the job. Here that means handling water coming down a hillside lot, or soft soil near the bay that has to come out before it can pull a slab down with it.
Concrete services we offer in Corte Madera
Concrete driveway building
Driveways here often sit on soft ground near the bay or climb a sloped lot, so we dig out and pack the base before any concrete goes down.
Concrete patio construction
A backyard patio that tips toward the house sends water where you don't want it, so we set the slope away from your walls before we pour.
Stamped concrete services
Stamped concrete gives a patio or entry the look of stone or brick, and it still needs the same packed base underneath to stay level.
Concrete sidewalk building
We replace walks that have heaved or sunk, and cut control joints, shallow grooves in the surface, so any cracking follows a line we chose.
Garage floor concrete
Garage floors in older homes here that have cracked or settled can be broken out and repoured on a packed base, with a smooth finish that sweeps clean.
Decorative concrete
Colored or textured concrete suits entries and garden paths on homes where plain gray would look out of place, and we talk through upkeep before you choose.
Concrete retaining walls
On hillside lots, a concrete retaining wall holds back soil for a flat yard, with drainage behind it so water doesn't push it over.
Concrete floor installation
Interior concrete floors work well for workshops, studios and additions, and we prepare the subgrade, the soil the slab sits on, before setting the finish height.
Concrete pool decks
Pool decks need a surface that grips wet feet and a slope that carries splash water away from the pool and the house, which we plan before forming.
Concrete steps construction
We rebuild front steps on homes set above the street with even step heights and rebar, steel bars inside the concrete, to hold them together.
Slab foundation building
A slab foundation for a new home or addition starts with what's under it, and on softer ground near the bay that prep is most of the job.
Foundation installation
We form and pour foundations for additions and rebuilds to the approved plans, with forms checked for size and height before any concrete arrives.
Concrete parking lot building
Lots for shops, offices and apartment buildings take steady traffic, so we build them thicker than a home driveway and plan drainage across the whole surface.
Concrete footings
Footings carry decks, fences, posts and small additions, and we dig and pour them to suit the soil we find, which near the bay is often soft.
Foundation raising
When a house on settling ground has tilted floors or sticking doors, raising the foundation can bring it closer to level, and I'll tell you plainly what's realistic.
Concrete cutting
On older patios and driveways here, we saw-cut out the damaged section so you replace only the part that's failed, not the whole slab.

What we know about getting concrete work done in Corte Madera
Permits here go through the Town of Corte Madera's Building Division, which checks applications against state and local codes and inspects the building work, so whether your driveway, patio or wall needs a permit is the city's call, and their office at 415-927-5128 is the place to ask. When a job does need one, we help with the application and plan our start around the city's approval and inspections, which is why a permitted job usually can't begin the week you call. You can check any contractor's state license with the Contractors State License Board and ask whether they hold a Corte Madera business license, and I'm happy to answer either question for us. We're licensed and fully insured, and our work is backed by our satisfaction guarantee.
The price on a job here moves with what I find on the visit, mainly the size and thickness of the slab, whether old concrete has to be broken out and hauled off, how much soft soil has to come out before we pack a new base, and how close a concrete truck can get on a narrow or steep street. The schedule turns on the city's review when there's a permit and on curing, the days fresh concrete needs to gain strength before you use it. Your written estimate spells out each of those for your property, the same way we write them for homeowners in Mill Valley.
Soft bay ground and sloped lots wear on concrete
Mariner Cove and Marina Village, the bayside neighborhoods built on filled baylands, have settled as much as four feet since they were built, depending on how thick the bay mud is underneath, and in some spots that's left homes with tilted floors and storm drains that no longer flow the way they were designed to. On your property that shows up as a driveway that dips, a patio that tips back toward the house, or water pooling where it used to drain. We can't stop ground like that from moving, and I'd rather say so plainly, but we can dig out the soft top layer, pack a solid base, add rebar and set the slope so water runs away, which gives a new slab its best chance.
Up the hill, the trouble is usually water rather than mud. Runoff coming down a slope works under walks and steps and washes out what's beneath them, so on those lots we look at where the water runs before we price anything, and add drainage or a retaining wall when the slope calls for it.
What to expect when you hire us in Corte Madera
From your first call to the final walk-through, here's how a job runs with us, and where the city's steps fit in when your project needs a permit.
Call or send the form
You call (707) 283-3110 or send the form with a few lines about the job. We set a time that suits you for me to come out and see it.
I look at your site
I check the ground, the drainage and how a truck will reach the pour, and ask how you'll use the space, so it helps if you can be there. You get a written estimate that lists what's included, base work and all, so nothing in the price is a mystery.
We sort out city steps
Once you're ready, we take care of any city steps and set a date with you. Then our own crew digs out, packs the base, forms, pours and finishes, cutting the control joints while the concrete is fresh.
We walk the finished job
I walk the finished work with you before we pack up and tell you when it's ready for feet and when it's ready for cars. Staying off it until then lets the concrete cure properly, which matters more than most people expect.
Questions about concrete work in Corte Madera
Do I need a permit to pour a foundation for an addition in a Corte Madera flood zone?
Yes. If your property is in Corte Madera's Special Flood Hazard Area, any new development or an addition or renovation to an existing structure needs a Floodplain Development Permit. Part of the city lies in that area, and the city's Public Works Department can help you check whether your lot is one of them. If it is, tell me on the visit so the estimate allows for it.
Does a concrete contractor need a California state license to work in Corte Madera?
Yes, in most cases. California requires a state contractor's license whenever a job needs a building permit, uses any additional workers, or comes to $1,000 or more in labor and materials, and contractors need it before they even bid. For nearly any driveway, patio or wall, that means whoever gives you a price should already be licensed, and you can look the license up with the board before you sign.
What building codes apply to concrete plans in Corte Madera?
Plans submitted to the city now have to follow the 2025 California codes, including the building, residential, energy and wildland-urban interface codes, with the city's own amendments added. Corte Madera has a wildland-urban interface boundary that's treated as a very high fire hazard zone under state law, so wildfire rules can apply to work inside it. If your job needs drawn plans, we build to whatever the approved set calls for.
How do I schedule a building inspection for a permit in Corte Madera?
You schedule it through the city's Online Permit Center once you've registered as a user. The same account lets you search a property's permit history, pay fees and see inspection results, which is handy for checking whether earlier work on your lot was signed off.
What causes new concrete to crack or sink near the bay in Corte Madera?
Most of the time it's what's underneath, a base that was raked level instead of dug out and packed, sitting on soft ground that keeps settling. Water running toward the slab, joints cut too late or not at all, and a pour in the heat of the day that leaves a weak, dusty top all add to it. Concrete can still crack, and I won't tell you otherwise, but packing the base, setting the slope, cutting joints on time and letting it cure is how we keep cracks small and in places we chose.
How much does a new concrete driveway cost in Corte Madera?
It depends on what I find on the visit, mainly the size, the ground prep and the finish, so your figure comes in a written estimate after I've seen the site. A broom finish, the light texture brushed in for grip, costs less than stamped or colored concrete. If the budget is tight, I'd rather you save on the finish than the base, because the base is buried on day one and decides how the slab holds up for years.
