Concrete work for Cotati homes
Most Cotati calls start with a cracked driveway, a sinking patio or an uneven walk. Summer fog often slips in through a gap in the ridges near Petaluma, so Cotati runs cooler and grayer than Santa Rosa. Concrete sets and cures slower then, so we time the pour and the finishing to the day.
We're a concrete contractor based in Santa Rosa, working the cities around it, like Windsor and Rohnert Park. Cotati's Building Division permits most work on a property, with a few exceptions, so I check with the city before we bid. If you need a permit, we handle it and meet the inspector, and it sets the start date along with the weather.
Concrete work we do in Cotati
Get a quoteConcrete driveway building
When the old driveway is cracked and sinking, we tear it out, dig down to firm ground and pack a new base before the steel and the pour.
Concrete patio construction
A patio slab off the back door, sloped so rain runs to the yard and not toward your house, with a finish that suits bare feet and chairs.
Stamped concrete services
Concrete pressed with a pattern and colored to look like stone, brick or slate, for a patio or walk that should look like more than plain gray.
Concrete sidewalk building
Front walks and side paths replaced where a lifted panel trips people, then given a broom finish, a light dragged texture so shoes grip in the wet.
Garage floor concrete
A garage slab poured thick enough for the car and the workbench, with control joints, the cuts we make on purpose so shrinkage cracks follow a straight line.
Decorative concrete
Colored, exposed-aggregate or saw-cut patterned surfaces for patios, walks and entries. Tell us the look you want at the estimate and we'll show you what holds up outdoors.
Concrete retaining walls
Poured walls that hold back a slope where a yard steps down, built on footings with steel inside and drainage behind so water doesn't push them over.
Concrete floor installation
Interior slabs for shops, studios and additions. We prepare the subgrade, the packed ground the slab sits on, so the floor stays flat under whatever sits on it.
Concrete pool decks
The deck around a pool, sloped away from the water and finished for grip, so splash drains off instead of pooling where people walk barefoot.
Concrete steps construction
Front and back steps formed so every step is the same height, since the odd one is the step people trip on, and tied into the walk or slab.
Slab foundation building
A slab foundation for a new home, garage or backyard unit, with the base, steel and plumbing sleeves checked before the pour, because none of it can move afterward.
Foundation installation
Perimeter foundations and stem walls for homes and additions, laid out to the plans and checked for square and level before any concrete arrives.
Concrete parking lot building
Parking areas and wide aprons for shops, churches or multi-unit properties, built thicker on a heavier base because cars and delivery trucks load it every day.
Concrete footings
Footings for decks, posts, walls and additions, dug to firm soil and sized for what sits on them. They're small, but they carry the whole load.
Foundation raising
When floors slope or doors stick because a foundation has dropped, we lift it back toward level and support it from below so it holds.
Concrete cutting
Saw cuts for a new doorway, a drain line or a damaged section, so we replace only the part that's failed instead of tearing out the whole slab.

Why Cotati homeowners call us
On site from estimate to pour
I come out to every estimate myself and I'm on site the day we pour. Our own crew does the work, so you're not handed off to strangers.
Money goes into the base
Price turns mostly on size, finish and how much digging the base needs. If money's tight, I'd cut the finish before the base, since the base decides whether the slab sinks.
Licenses you can ask about
We're licensed and fully insured. Cotati also requires a city business license from every business working here, even one based in Santa Rosa, so ask anyone you hire about both.
