Permit questions in Vallejo start with the city's Central Permit Center, which you can reach through the City of Vallejo website. Before we schedule, I check with the city about your address. If the work needs a permit, we take care of the application and plan the job around it, so the permit and any slab repairs are usually what move the start date. Price follows the slab more than the coating. It turns on the size of the floor, how much grinding and crack repair the concrete needs, whether old paint or sealer has to come off, and which system fits how you use the space, and my written estimate spells out each of those for your floor.
Vallejo is on the far side of our area from Concord, so we plan around the drive and load the truck with everything for prep and coating before we leave, the same way we run a job in Pleasant Hill. If your building is on Mare Island, where there's a historic district, I bring that up when I check with the city before we schedule.
