Polished concrete finishes we grind to
Cream and salt and pepper
A light grind keeps the smooth cement surface, or goes a little deeper to show fine sand. These suit floors where you want a quiet, even look.
Full exposed stone
We grind deeper until the coarse stone in your slab shows across the whole floor. It suits a slab that was placed well and has stone worth showing.
What does it take to polish a concrete floor in Martinez?
Polished concrete flooring in Martinez, CA means grinding your existing slab to show its cement, sand or stone, then refining it to the shine you pick, so the look comes from the concrete itself instead of a coating sitting on top.
Most people who call me have a plain gray slab that looks unfinished, or an old coating that's peeling and needs stripping off first. The price moves with the size of the floor, how deep we grind for the look you pick, how many cracks and pinholes need filling and how high a shine you want. The schedule turns on the same things plus how easily the room can be cleared, and my written estimate lays out both for your floor.
Grinding, testing and sealing your concrete floor
Your slab decides what's possible, so I look at its stone and its flaws before we pick a finish. If polishing won't give you the look, we'll talk about stained concrete flooring or terrazzo flooring instead.
Sample patch first
We grind a sample patch on your actual slab, so you see how much stone shows and approve the real color first.
Grind in passes
Our crew grinds the floor in passes down to the level you approved, then refines it with finer passes toward the sheen you chose.
Test before sealing
We test the polish before any sealer goes on, since sealers can hide scratches, so your shine comes from the grinding.
Seal and clean up
Once the polish passes, we seal the floor, vacuum up the last of the dust and clear out our equipment.

I come out myself to look at the slab and give the estimate, and I'm on the job with our crew while they prep and polish.

Polished concrete questions we hear
Which polished concrete look suits my slab in Martinez?
The look your slab can support depends on the stone in its mix and how it was placed and finished, so your existing concrete narrows the choice. A cream finish shows mostly cement, salt and pepper shows fine sand, and full exposure shows the coarse stone. Color can shift a lot between them, since a cream finish that looks gray may turn brown once the surface paste comes off, which is why we start with the sample patch.
How shiny can a polished concrete floor be?
You choose the shine separately from the stone, because the industry's polishing classes set a range of sheen levels on top of how much aggregate shows. So you're really making two picks, how much stone and how much gloss. Tell me how the room gets used when I come out, and we'll talk through which level fits.
How much does polished concrete flooring cost in Martinez?
Polishing concrete across the US usually costs about $8 to $9 per square foot, and that's a national figure, not our price. Your own cost turns on the floor's size, how deep we grind, how much filling it needs and the shine you pick, and my written estimate gives you the number for your floor.
How do I polish a concrete floor that has pinholes and small cracks?
Floors with a lot of pores, like sand pop-outs, tiny cracks, pinholes or air voids, generally need grouting worked into the surface to reach the finish you picked. If your slab shows these, ask whether grouting is part of the plan, and I'll point them out when I look at the floor.
Will my polished concrete floor look like the photos I've seen online?
Probably not exactly, because polished concrete varies from one area to another with the type, size and spread of the stone in the mix. A floor in a photo from somewhere else was ground from different concrete, so we'd rather show you a patch of your own.
How do I keep concrete dust under control when a floor is polished indoors?
California's safety rules require a dust reduction system whenever powered tools grind concrete, either a water feed at the cutting surface or a dust collector the grinder's maker recommends. Indoors, the state also calls for a HEPA-filtered vacuum, a fine-dust vacuum, to pick up loose dust between grinder passes, so ask any crew how they handle dust before they start.

Polished concrete flooring in Martinez and nearby
In Martinez, the city's Building Department issues building permits to homeowners and licensed contractors for work inside the city limits, and new applications, residential ones included, now go in online through the city's portal. I won't guess whether polishing your floor needs one, so we sort out with you which city or county office covers your address and who pulls the permit, and we work with that office from there.
Most of what we polish around here is home garages and working shops, and older slabs often carry old coatings or patches that have to come off first. We're based in Martinez and do the same work in Concord, Benicia and the cities around them in Contra Costa and Solano counties.
