A grit sequence run all the way out, not a coat of gloss sprayed over a tired floor.
Polished concrete gets sold two ways in this market. One is a real mechanical polish: a machine walks the floor eight to eleven times with progressively finer diamonds, a densifier hardens the surface chemically partway through, and the shine you end up with is the concrete itself. The other is a wax or a gloss coating over a lightly buffed slab, sold at half the price, and it looks great for about a year.
We only do the first one. That matters for what you'll pay and what you'll get, so this page is mostly about where the money actually goes. No dollar figures here, just the honest list of what makes one floor a two-day job and another a two-week one.
Start with the sequence. Metal-bonded diamonds do the cutting at the low end, somewhere around 30 and 50 grit depending on how flat the slab came out and how much aggregate you want showing. Then 100 and 200. Densifier goes down in there, soaking in and reacting with the concrete to harden the surface from within. After that we switch to resin pads and climb: 400, 800, 1500, and 3000 for the high gloss floors. Every one of those passes is a machine going over the whole floor, edging the perimeter by hand, and vacuuming behind itself.
Nobody pays for diamonds. They pay for passes. Skip four steps and you save real time, which is exactly what the cheap bid is doing, and the floor tells on it under raking light from a window within a season.
Grind lightly and you polish the cream, the fine cement-rich layer at the very top. It stays close to the floor's natural color, it's the least labor, and it depends entirely on that top layer being sound. Cut a little deeper and you get salt and pepper: the tips of sand and small stone showing evenly across the floor. Go all the way down and you expose full aggregate, a terrazzo look with rock faces reading across the surface.
Full exposure is beautiful and it's the expensive answer, partly from the extra cutting and partly because it's unforgiving. Once you're down in the aggregate, any place where the slab was poured thin, patched, or hit with a trench cut shows itself permanently. On new construction we can plan for it. On a slab poured twenty years ago in Castle Pines North with a plumbing repair down the middle, we usually steer clients toward salt and pepper and everybody ends up happier.
| Driver | Why it costs | How to hold it down |
|---|---|---|
| Coating or adhesive removal | The first cut clogs constantly and takes several passes before real grinding starts | Have flooring pulled well ahead and let us see the bare slab before we quote |
| Slab flatness | Low spots don't get touched until the high spots come down to meet them | Accept a lower gloss level, which hides waviness far better than a mirror does |
| Depth of aggregate exposure | Cutting into stone means more time on metal-bond diamonds and more of them consumed | Choose salt and pepper over full exposure unless the slab is new and clean |
| Final gloss level | Every step past 800 grit is a full additional pass across the whole floor | Stop at 800 for living space; save the 3000 mirror for an entry or a display area |
| Layout and obstructions | Edge work near walls, columns, and closets happens on hands and knees | Polish open areas fully and use a different finish inside small closets |
We'll grind a two-foot test square and show you the aggregate before you commit to anything. That look costs you nothing.
Clients ask which gloss level is best. There isn't one. A satin floor in a mudroom hides sand from the trail all week. A mirror in a great room shows every footprint by Tuesday. We ask what happens in the room before we ever talk numbers.What our crew lead tells homeowners
Polished floors are an indoor product. That isn't a preference, it's physics: a dense, sealed surface outdoors at this altitude gets slick when wet, and freeze-thaw works on a hard-troweled top layer the way it works on any tight surface. For exterior slabs we'll steer you to a washed or broomed finish and put the polish inside where it belongs.
Inside, the calendar is wide open. We polish in February as readily as in July, which makes this good winter work while exterior crews wait out the ground. Custom builds in Lagae Ranch and Daniels Gate usually want us after drywall and before cabinets so the slab is protected during the rest of the trades. Lower levels in The Village at Castle Pines and remodels in Castle Pines North come to us later, once the carpet is out and the room is empty. Either way we ask for the space cleared, because polishing around furniture doubles the edge work.
