Alamo isn't an incorporated city, so Contra Costa County handles building permits and inspections here, and the county says almost all projects in its unincorporated areas need a building or grading permit. Before we put your floor on the calendar, we check with the county about your job, and if it needs a permit, we take care of the application and plan the work around it, so that answer is usually the first thing that sets your start date. Two things are worth checking on any contractor you hire here: a state contractor's license from the Contractors State License Board, and a county business license.
We're based in Concord, a short drive from Alamo, and we work here the same way we do in Walnut Creek and the other cities around us. What moves the price on an Alamo floor is mostly how much work the slab needs before anything goes on it, then the size of the space and the system you pick. The schedule turns on that same prep and the permit answer, and your written estimate gives you your own figure with the reasons behind it.
