Whether your job needs a permit is the City of Agoura Hills' call, so before I price anything I check what the city asks for at your address and tell you what I found. If an approval is needed, we plan the start date around it, and that's usually the first thing that sets the schedule. You can check two things on any contractor you're considering. One is a state license from the California Contractors State License Board. The other is a current city business license, which in Agoura Hills runs one year from the day it's issued and has to be renewed before then. We're fully licensed and insured, and for questions about your own lot, the city has the final word.
The price moves with the size of the slab, how much old concrete we break out and haul away, how deep the base has to go, how much rebar goes in to hold the slab together, and the finish, from a plain broom finish with a light texture for grip up to stamped. Access counts too, because some hillside and canyon streets are tight for a concrete truck, and a steep lot can mean a pump or a retaining wall. Your written scope breaks each of those out with its own price. We take the same kinds of jobs in Westlake Village and the other cities around Malibu.
