In Concord, permits go through the city's Permit Center, and when a job needs one, the review and inspections set part of the schedule, so I sort that out before we put you on the calendar. The city's list of work needing a permit on single-family homes names things like roofs, water heaters and windows, and it doesn't settle driveways or patios either way, so we check your address with the city instead of guessing, and when a permit's needed we handle the application and set up the inspections. Two things are worth checking on any contractor you're comparing, us included. The state licensing board requires a license when a job needs a building permit, uses any extra workers or runs $1,000 or more in labor and materials, and the city requires its own business license of contractors who work here, even ones whose office is in another city, like ours in Vacaville.
What moves the price on a Concord job is mostly what's under and around the slab: how much old concrete comes out, how far we dig to reach firm subgrade, the ground the slab actually sits on, how big and thick the slab is, how close the truck can get, and whether you want a broom finish, the light brushed texture that keeps a driveway from getting slick, or stamped work. The schedule turns on the permit, if there is one, and on curing, the days new concrete needs to harden before it carries feet and then cars, and your estimate spells all of that out. We drive over from Vacaville for this work the same way we do for jobs in Napa, and we usually start Concord pours early in the day, which also keeps fresh concrete out of the midday heat that can leave a weak, dusty top.
