Napa neighborhoods from the river to the hills
We're a short drive over from Petaluma, and most of what we're asked to do in Napa is at people's houses: driveways, back patios, front walks and steps, with the odd slab for a shop or a small business. Older homes sit close to downtown and the river, and newer neighborhoods spread out toward Alston Park and Westwood Hills, so in a single week we might break out a tired driveway on a narrow older lot and pour a patio on a sloped yard.
The Napa River runs through the middle of town with low ground and wetland along its banks, while the west side climbs into hills with oak groves. That split shapes most of our dirt work, because near the river we spend our time on where the water will go, and on the slopes we're dealing with grade, tree roots and holding the soil back.
Concrete work we do on Napa properties
Concrete driveway building
When a Napa driveway has cracked, sunk or tipped toward the garage, we break it out, pack a new base and pour it sloped away from the house.
Concrete patio construction
A Napa patio that holds water or has sunk usually sits on soft ground, so we dig out, pack the base and pour it sloped to shed rain.
Stamped concrete services
Stamped concrete presses a stone or tile pattern into a Napa patio or front walk while it's wet, over the same packed base we use for plain work.
Concrete sidewalk building
Front walks and side paths on older Napa lots often get lifted by tree roots, so we replace the heaved sections and broom-finish them for grip.
Garage floor concrete
Garage floors in older Napa homes are often cracked, stained or uneven, so we pour a new slab with an even surface you can park on and sweep.
Decorative concrete
Decorative concrete adds color, scored patterns or exposed stone to entries and courtyards on Napa properties, where the slab is part of how the house looks.
Concrete retaining walls
Sloped Napa yards often need a retaining wall to hold back soil, and we build ours on a footing with drainage behind so water doesn't push it over.
Concrete floor installation
For shops, barns and outbuildings around Napa, we pour interior concrete floors that stay level under equipment and are easy to keep clean.
Concrete pool decks
A Napa pool deck has to grip when it's wet and drain away from the pool, so we plan the slope and the finish together.
Concrete steps construction
Front steps on older Napa houses often pull away from the porch or crumble at the edges, so we rebuild them on footings that hold them in place.
Slab foundation building
For a Napa addition, garage or backyard cottage, a slab foundation gives you floor and footing in one pour, set on ground we've dug out and packed.
Foundation installation
New construction and rebuilds in Napa need a foundation poured to the approved plans, and we form it, set the steel and pour around the city's inspections.
Concrete parking lot building
Small businesses and property owners in Napa need parking areas that carry cars and delivery trucks, so we pour thicker slabs over a deeper packed base.
Concrete footings
Footings carry a wall, deck post or porch to firm ground, and on Napa lots near the river or on a slope we dig until we reach it.
Foundation raising
When a Napa house has settled at one corner and doors start sticking, foundation raising lifts it back toward level, and I'll tell you on site what's realistic.
Concrete cutting
We saw clean openings and edges in Napa slabs and walls, so you can widen a driveway or take out a damaged section without breaking up the rest.

Working in Napa: permits, licenses and what sets the price
Concrete work inside the city goes through the City of Napa's Building Division, which enforces the building standards for every structure in town, so that's the office that decides whether your job needs a permit. Work that needs no plans can get its permit over the counter, which keeps that step short, while anything that needs drawings has to wait on review. If you're checking out contractors, know that the city issues its business license for revenue only, so it shows a business is set up to work in Napa and says nothing about how well it pours concrete.
As a concrete contractor based in Petaluma, CA, we come over to Napa the same way we head to Sonoma, and when your job needs a permit we help with the application and set our start around the city's approval and inspections. The price turns on the size of the slab, whether an old one has to come out first, how much digging and base the ground needs and the finish you pick, and the schedule turns mostly on the city's steps and the days the concrete needs before you use it. I put all of that in a written estimate so you can read it line by line. We're licensed and fully insured, and our work is backed by our satisfaction guarantee.
Why Napa slabs crack, sink and hold water
Most of the cracked and sunken driveways we look at in Napa were poured over dirt that was raked flat instead of dug out and packed, so the subgrade, the ground the slab rests on, kept settling and the concrete went down with it. On older lots you'll often find a slab that falls toward the garage or the house, which sends water to the one place you don't want it, or a corner lifted by roots from a big yard tree. We dig down to firm ground, pack the base, and set the grade so water runs away from the house before any concrete shows up.
I won't tell you a new slab can't crack, because concrete shrinks as it cures and nearly all of it cracks somewhere. What we control is where, by adding rebar, steel bars that hold the pieces together and level, and by cutting control joints, shallow grooves across the slab, early enough that the cracks follow our lines instead of running wherever they like.
How a Napa concrete job runs from the first call
Here's how it goes from your side, from the first call to the final walk-through, with a written estimate in hand before you decide anything.
Call or send the form
Tell us what you have in mind by phone or through the form, and we'll set a time for me to come see the site. It helps if you're home for that visit so we can talk through how you'll use the space.
I walk the site and estimate
I check the ground, the drainage and any old slab, ask how you'll use the space, and send a written estimate that lists what's included. That way you can see exactly what you'd be paying for before you spend anything.
We handle the city steps
If the job needs a permit, we help with the application, and work with no plans can get its permit over the counter at the Building Division, which is open to the public 8 AM to 4 PM Monday through Thursday. Once the city is ready, we set your start date around its approval and inspections.
We pour and walk it together
Our own crew digs out, packs the base, forms, pours, finishes and cuts the joints, and you don't need to be home for most of it. When we're done I walk the finished job with you before we pack up and leave the curing instructions in writing.
Questions about concrete work in Napa
Do I need a permit to pour a concrete driveway or patio in Napa?
Check with the City of Napa's Building Division before work starts, because the city's list of work that needs no permit doesn't name driveways or patios. That list does name one-story sheds of 120 square feet or less, fences no taller than 7 feet and short retaining walls. I'll go over what your job may need at the estimate visit.
Does a concrete retaining wall need a permit in Napa?
A retaining wall 4 feet tall or less, measured from the bottom of its footing to the top of the wall, is on the city's list of work that needs no permit. That exemption ends if the wall carries a surcharge, extra weight such as a driveway, a building or a slope pushing down from above, or holds back fuel or other flammable liquids. I measure the height and look at what's above the wall when I come out.
Can I submit building permit plans online in Napa?
No, the City of Napa has no online portal for submittals, so plans go to the Building Division in person. Plans for minor projects that take a short time to review are checked right at the counter, and larger jobs take longer. When we help with your application, we'll tell you what to bring.
How do I find out which building codes apply to my Napa permit?
A permit you apply for in Napa now has to meet the 2025 California codes, which the city has adopted with its own local amendments, and the city's permits and plan review page sets out that rule. Work that's exempt from a permit still has to meet the codes and the city's ordinances, so we build to them either way.
How much does a new concrete driveway cost in Napa?
It's priced from your driveway's size, the old slab coming out, the base and the finish, so the written estimate is where you'll see your number. A plain broom finish costs less than stamped or colored work, and rebar and extra thickness add to it where the ground or the load calls for them. If the budget's tight, I'd trim the finish before the base, because nobody sees the base on day one but it's what decides whether the driveway settles.
How long does new concrete need to cure before I can use it?
You'll be on a new slab on foot well before you can drive on it, because curing, the time concrete takes to harden and gain its strength, keeps going after the surface looks dry. Use it too soon and the top can chip or crack, so I give you the waits for your slab in writing when we finish.
