Oak View is unincorporated, so the County of Ventura is your local government, not a city hall. If your job needs a permit, I'll tell you at the estimate, and we'll handle the application and inspections with the office that issues it so that part isn't on your plate. Contractor licensing is a state matter. The Contractors State License Board licenses contractors across California, Oak View included, so ask anyone you're talking to for their state license. We're licensed and fully insured.
Price comes down to how big the slab is, how thick it needs to be, how much old concrete and soft dirt we have to dig out, how close the truck can get and which finish you pick. The schedule turns on the base prep and on curing, the days fresh concrete needs to gain strength before it can take weight. Your written estimate spells out what's included, the same way we write them up for homeowners in Westlake Village and the other cities around Port Hueneme.
