Terrazzo Restoration Cost Calculator

Pick the floor area, what is on the terrazzo now, what shape it is in, and how much shine you want, and this gives you the typical range for that floor. It is built from the same numbers on the pricing page, there is no email gate, and the answer appears on the page as you change the dropdowns.

Two honest notes before you use it. The job minimum is real: mobilizing planetary grinders, water, tooling, and a crew costs the same whether the floor is one bedroom or the whole house, which is why a single room lands at $600 to $1,000 and why doing the whole floor at once is always the better buy per square foot. And the biggest unknown in terrazzo pricing is not the terrazzo. It is what is on top of it, which is why the covering question moves the number more than anything else here.

What each answer changes

• Floor area carries most of the cost, at $4 to $8 per square foot for the grind and polish. Larger floors sit nearer the bottom of that range because the crew mobilizes once and the machines run continuously.
• What is on it now is the swing factor. Nothing at all, which is common in houses that were gutted after a flood, means no removal charge. Carpet and glue is $2 to $3 per square foot. Tile and thinset is $4 to $5, the most expensive thing to find, and it usually brings pitting with it, covered on the ridges after tile removal page. An old coating is ground off in the same metal-bond passes but adds time, which is why it carries a smaller line of its own.
• Condition adds repairs and stain work. Patches are $75 to $250 each and the tool assumes a handful; stain and rust treatment is $150 to $600 per area and only applies to marks that survive the grind, which most do not. The rust rings page explains which ones grind out for free.
• Finish is time on the floor. Matte and satin stop around 400 grit. High gloss runs up through 1500 or 3000, and every step past 400 is another pass, which is why it is a multiplier rather than a flat add.

What the calculator cannot see

Three things, and all three get found the same way, by exposing the slab.

Under tile, nobody knows what the terrazzo looks like until the tile is off. That is not a sales line; it is why the pricing page says the final number is confirmed once the slab is exposed.

Hollow areas do not show in a photograph. If a section has lost its bond to the slab, it gets stabilized or replaced before any grinding starts, because a planetary grinder can break up loose material. The hollow spots page shows how to sound your own floor with a golf ball in twenty minutes.

And a full perimeter of tack-strip nail holes is priced by the room rather than per hole, because a 12 by 14 bedroom has a 52-foot perimeter and somewhere between 200 and 300 holes in it. That line is quoted after a look, so it is deliberately not in the tool.

If you only need repairs and no polishing, the repair-only estimator prices that visit instead. If you want the full sequence explained first, start with the restoration page.
