Flooring contractor jobs in Concord, CA

Concord is the next city over from us in Martinez, and the calls we get there cover a lot of ground. There are garages in established neighborhoods with years of oil on the slab, newer homes where the builder left bare gray concrete, and shops and warehouses on the commercial side that run carts and spill chemicals every day. We do the same work in Pleasant Hill and Walnut Creek next door and up in Vallejo. The price on any of them moves with the floor's size, its condition and how much old coating has to come off, and the schedule turns mostly on prep and how long the system you pick needs to cure, so I'll give you your own number when I come out to see the floor.

What shapes a Concord job is usually what's already on the concrete. Old sealer, paint or a coating that's lifting has to come off, and cracks and damp spots get found before anything goes down, because a coating is only as good as the slab it's stuck to.

Floor work we do in Concord

What Concord slabs ask of a coating

I started this business in Martinez in 2017, after learning coatings on my own garage and then beside experienced crews. What's different is where the time goes. We put it into testing and grinding the slab before any color goes down, because that's what keeps a floor bonded.

  • I look at your floor myself

    I come out to Concord myself to check the slab and give the estimate, so the person pricing your floor has seen what's under it.

  • On the job with our crew

    Our crew does the grinding and install, and I'm on site with them, so a crack or damp spot we find gets dealt with instead of coated over.

  • Know the plan before you sign

    I walk you through what we'll do and why, from the grinding to the system that fits your floor, before you sign anything, so you can compare bids fairly.

Concord floor questions we hear

How much does an epoxy garage floor cost in Concord?

Your price comes down to the size of the slab, its condition and the coating you choose, and I'll give you that number when I come out to see the floor. Cracks to fill, a damp slab or an old coating to strip all add work, while a sound slab with a basic epoxy system keeps it lower. Polyaspartic and metallic finishes usually cost more.

Do I need a permit for a garage floor coating in Concord?

Concord's permit list doesn't answer it either way, so check with the city's Permit Center before you assume you can skip one. The city's partial list for single-family and duplex homes, from an older bulletin, names work like roofs, water heaters, windows and air conditioning, but not floor coatings. If your job does need a permit, we work out with you who pulls it and deal with the city from there.

How do I find out which permits my Concord floor project needs?

Start with the Permit Center page linked above, which points you to a way to look up zoning, see which permits a project needs and estimate the fees. It's worth doing before you ask for bids. If the job moves soil or reaches the public strip along the street, the city also wants separate grading or encroachment permits from its Engineering Division, so plan for that step early.

Does a contractor based outside Concord need a Concord business license?

Yes, the city requires a business license to do business in Concord, and that includes state-licensed contractors whose office sits outside the city. So a crew driving in from Martinez, like ours, falls under the same rule as one based in Concord.

When does a flooring contractor need a California license?

A California contractor needs a state license when the labor and materials on a project's contracts total $1,000 or more, when the job needs a building permit, or when it uses any additional workers. The Contractors State License Board licenses anyone who builds or alters a building in the state, and we're licensed and fully insured.

How do I check if my Concord address is in an earthquake hazard zone?

Type your address into EQ Zapp, the California Geological Survey's statewide map, and it shows whether the property sits in any of its mapped earthquake hazard zones. It won't tell you about your slab itself, so I still look at the cracks in person when I come out.
