Concrete floor installation in Santa Clara CA - a floor finished at the right time

Most calls start with an old floor that has cracked, sunk at one end or started to dust, or with a garage floor, shop or addition that needs a slab for the first time. The price moves with the size of the floor, how much old concrete has to come out, how much digging and base work it needs and the finish you want, and the schedule turns more on the permit, a dry stretch of weather and the cure than on the pour itself. The estimate is where you get your own numbers, written out so you can see exactly what's included.

We break out and haul away any old concrete, then dig down to firm ground and pack the subgrade, the soil the slab sits on, so the floor doesn't settle later on loose dirt. We lay and compact the base, set rebar, the steel bars that hold the slab together if it cracks, and set the forms at a height and pitch that send water away from the house instead of toward it. I'm there on pour day, and we start early so the top doesn't dry out in the afternoon heat and turn weak and dusty. Finishing a floor is all timing, the same as getting a plate out at the right moment, so the crew works each pass when the concrete is ready and not before. We cut the control joints, shallow cuts that give the slab a planned place to crack, while the concrete is still young, then keep it covered and damp while it cures, which is the wait while concrete gains strength before you use it. If the budget gets tight, I'd rather you spend it on the base than on a fancy finish, because the base is the part nobody sees on day one and the part that decides whether the floor stays flat.

A floor rarely stands alone. If the slab meets a back door that sits above the yard, we build concrete steps to the same finish, and if it runs out toward the pool we can plan concrete pool decks with it so the levels and drainage line up.

The City of Santa Clara requires a building permit before anyone builds, enlarges, alters, repairs or improves a building or structure, and the city decides whether your floor falls under that, so I check with the city for your address while I put the estimate together. When we're the ones pulling the permit, we handle the paperwork and the inspections. The state also maps areas where liquefaction, ground turning soft and loose in a strong earthquake, may occur, and if your property sits in a mapped zone, that hazard may need to be looked into and dealt with as part of the permit. When a job calls for an engineer, we bring one in and work from their plans.

On pour day, the city asks residents to keep concrete and wash water out of streets, gutters, storm drains and waterways, so we rinse tools and the chute in a contained spot and leave the gutter clean. We're based in Santa Clara and keep that same cleanup on floor jobs across the cities around it, including Sunnyvale and Milpitas.
