In Chino, building permits come from the city's Building Division, which requires one for all work except what the state codes exempt, so if your job needs a permit, the pour waits until it's issued. When it does, we apply for it with the city and keep track of it, so you don't have to. Before you hire anyone, ask to see a California contractor license and a Chino city business license, which the city requires of anyone doing business there, out-of-town contractors included. We're based in Rancho Cucamonga, so ask us the same as you'd ask anyone else.
What moves the price is mostly what you can't see once the job's done: how much old concrete we break out and haul off, how much digging and packing the base needs, and how thick the slab is and whether it gets rebar, the steel inside that holds the pieces together if it cracks. The finish matters too, and a broom finish, the brushed texture that gives shoes and tires grip, runs less than stamped or colored work. If the budget's tight, cut the finish, not the base, because a plain slab on a packed base outlasts a fancy one on raked dirt. Your schedule turns on the permit if there is one, the weather and the cure, the time concrete needs to gain strength before you walk on it, and longer before you drive on it. Your written estimate lays all of that out for your job, the same way it does for the homeowners we pour for in Glendora and back home in Rancho Cucamonga.
