A polished, stained concrete floor fills a bright industrial garage with a roll-up door and open bay.

Is polished concrete right for my floor?

Polished concrete flooring in Concord, CA is bare concrete ground with machines in steps until the whole surface is refined, so you end up with a hard, shiny floor and no coating on top. Concord Precision Epoxy Flooring polishes floors in homes, garages, basements and shops.

Most people who call about polishing have a slab they'd like to show off, or one they've just found under old carpet or tile and want to know what it'll look like. The price moves with the size of the floor, its condition, how much stone you want showing and how high a shine you want, because more stone and more shine both take more grinding passes. The schedule mostly depends on the slab itself, meaning any cracks or old patches to deal with, and on whether the city needs a permit. I'll give you your own figure in a written estimate once I've seen the floor.

How we do polished concrete flooring

I start by looking at the slab and asking how you'll use the room, because a polished floor shows what's in the concrete instead of hiding it. Then we pick two things together, one of three classes for how much stone, or aggregate, shows and one of four sheen levels, so we both agree up front on what the finished floor looks like. An older slab shows its history once it's polished, old patches and cracks included, so I walk you through what yours will show before we start. The look also depends on the type, size and spread of stone in your concrete, so we can show you samples or a mockup before anything gets ground. After that, we grind in steps, each finer than the last, until the whole surface is refined and at the sheen you chose.

If you want color, stains can be built into a polished floor, and our stained concrete flooring page covers how that works. If you're after more stone and pattern than your slab holds, terrazzo flooring is a floor built around the stone and color you choose.

Polishing the slab you have

This suits a sound slab where you're fine seeing its character, marks and all. It's the most direct route to a polished floor, since we work the concrete that's already there.

A polished overlay over a rough slab

A polished overlay is a decorative layer bonded and cast over your existing slab, made to be diamond ground for a polished look. It suits a slab too patched or uneven to show off as it is.

A lower sheen where the floor works hard

The higher the sheen, the sooner a floor shows wear, so for garages, shops and busy entries I usually point people to a lower sheen. Save the high gloss for rooms with lighter traffic where you really want the shine.

I come out to look at every job and write the estimate myself, and I'm on site working with our crew when the job gets done. The person who told you what your slab will show is the same one watching the grind.

We find out what the slab is doing

Most failed floors I've looked at went wrong because of what was under them. Since I started this business in Concord in 2023, checking the slab has come first, so you hear about cracks, patches and uneven spots before you pick a finish.

Planning polished concrete flooring in Concord

In Concord, the city's Permit Center handles permits, and its Project Pal tool shows which permits a project needs and estimates the fees. I don't assume a floor job does or doesn't need one, so before we schedule, we check with the city or county office that covers your address, and if your job needs a permit, we take care of the application and plan the work around it. If you'd rather ask yourself, the Building Division answers at 925-671-3107, weekdays from 8 a.m. to noon and 1 to 4 p.m. Concrete also contains crystalline silica, and Cal/OSHA sets standards to control how much of it workers are exposed to, because it can cause silicosis, an incurable lung disease, as well as lung cancer and kidney disease. We plan the grind around those standards before it starts.

Around Concord we see plenty of garage and basement slabs that have been patched over the years, and older floors coming out from under carpet or tile. That history is exactly what a polish brings out, so it's the first thing I look for. We do the same work in Walnut Creek, Pleasant Hill and the other cities around us.

Questions about polished concrete in Concord

How much does polished concrete flooring cost in Concord, CA?

Polishing concrete across the US usually costs about $8 to $9 per square foot. That's a national figure and a starting point, not our price, and your slab's condition, the stone and sheen you pick and any repairs all move it. We're based in Concord and work in the cities around it, and I'll give you a Concord number in writing after seeing the floor.

Will cracks in my old slab show after polishing?

Yes, usually. On an existing slab, old repairs and cracks become visible once it's polished, and an uneven floor shows its stone unevenly. That's why we go over it before we start, and if you'd rather not see those marks, a polished overlay is the other route.

Is a glossy polished concrete floor slippery?

Not by the numbers we've seen. In reported tests, slip resistance changed with gloss level but not with how much stone showed, and every result well exceeded the required slip rating, even at very high gloss. A wet floor still deserves care, like any hard floor.

What is the best way to care for a polished concrete floor?

Keep stains and chemicals off it, because that's its weak point. Compared with coatings, polished concrete costs little to keep up over the years, but it has limited resistance to stains and chemicals, so wipe up spills like oil or cleaners quickly. If the room sees a lot of chemicals, ask me whether a coating would suit it better.

Which California contractor license covers concrete floor work?

In California, the C-8 Concrete Contractor class covers contractors who form, pour, place, finish and install flat and other concrete work. It's a fair question to ask anyone who quotes your floor.

How do I get started on a polished concrete floor in Concord?

Call (925) 536-0504 or use the form on this page, and have the room size handy along with photos of any cracks or repairs, since those show after polishing. I'll come out, look at the floor and write up what I'd suggest and why.
