Our concrete work in Simi Valley
We come over from Oxnard to build driveways, patios, steps and foundations in Simi Valley, the same work we do in Thousand Oaks, Moorpark and Carpinteria.
The price mostly follows the size of the slab, the digging and base work under it, and the finish you choose. The schedule turns on whether the city wants a permit and on curing, the days new concrete needs before you use it. Your written estimate lists what's included.
What we build for Simi Valley homes
Here's the concrete work we take on for homeowners in Simi Valley.
- New and replacement driveways
- Patios, walkways and steps
- Indoor concrete floor installation
- Slab foundations and footings
Finishes we build in Simi Valley
- Broom finish for grip
- Stamped and colored concrete
- Steel rebar to hold slabs together
Why Simi Valley homeowners call us
When I visit, I check the ground under the old slab and where water runs, because concrete over loose dirt usually settles, and a slab sloped toward the house sends water at your walls. I mark where the joints go, our own crew does the work, and I check in as it goes along.

Do I need a permit for a concrete driveway or patio in Simi Valley?
A foundation for a new building or an addition does, because the City of Simi Valley requires a permit before new building or adding on. Its permit list doesn't name driveways or patios, so we ask the Building and Safety Division at (805) 583-6723 before work starts, and when a permit is needed we file it and meet the inspector.
Does a concrete contractor in Simi Valley need a state license?
Yes, for most concrete jobs, because California requires a Contractors State License Board license when the work needs a building permit, uses hired workers or comes to $1,000 or more in labor and materials. The license has to be in place before a contractor even bids, and we're licensed and fully insured.
How soon does the city inspect concrete work in Simi Valley?
The city inspects the next workday when the request comes in by 4:00 p.m., and a request made after 4:00 p.m. on a Friday goes to the following Tuesday. We time the pour around that, and we keep the city's stamped approved plans on site, as the city requires.
Will a new concrete driveway in Simi Valley crack like my old one?
Any slab can crack, but the random cracks you see in older driveways usually come from a base that was only raked level or from joints cut late or skipped. We dig out and pack the subgrade, the ground the slab sits on, and cut control joints on time, so a crack has a straight groove to follow.
If something isn't covered here, call us or send the form, and I'll be glad to answer it.
