Terrazzo Repair-Only Estimator

This one is for floors that do not need the full grind and polish: a couple of plumbing holes, a crack, a stain that will not mop out, or a sealer that has run its course. Count the patches and stain areas, choose whether you want sealing, and the range comes straight from the pricing page. No email, no signup.

Read the minimum honestly before you plan around this. $600 to $1,000 covers getting a crew, grinders, water, and materials to your address for a repair-only visit, and it applies whether you have one patch or four. That is the real economics of the trade rather than a fee, and it is why the advice on nearly every small job here is the same: batch it. Get every hole, crack, and stain in the house done in one visit, or fold the repairs into a full restoration where they cost very little on top of work that is happening anyway.

What each answer changes

• Patches are the core line, at $75 to $250 each. A single plumbing hole is at the bottom. A long crack that has to be cut back to a divider strip and refilled with matched aggregate is at the top. The cracks page explains which is which, and the chips and pits page covers the doorway damage that usually comes in groups.
• Stain and rust areas are $150 to $600 per area, and this line only applies to marks that need a poultice or chemical treatment. Most shallow rust rings and dye bleed disappear during ordinary grinding at no extra charge, so if you are having the floor ground anyway, do not count them here.
• Sealing is $1 to $2 per square foot and only belongs on a floor that has already been restored. If the floor is dull, coated, or hazy, sealing it now seals the problem in. The sealing and maintenance page explains why the sealer is penetrating rather than a film.

The honest limit of a repair-only visit

A patch has to be ground flush after it cures. On a repair-only job that grinding is local, so the patched area ends up at a slightly different polish level than the floor around it, and the boundary is findable. The NTMA restoration guide is candid that color matching existing aggregates may not be exact, since marble is a mined product that alters over time, and it calls for a mock-up so expectations are set before the work starts. That applies doubly to a spot repair.

If you can see yourself restoring the whole floor within a few years, the repairs are worth waiting for and folding in. If the floor is already polished and you just need two holes gone, this is the right visit and this is the right number.

What is not in this tool

A full perimeter of tack-strip nail holes, because that is a per-room price quoted after a look. Delaminated or hollow sections, because the extent is unknown until the loose material comes up; the hollow spots page shows how to map yours with a golf ball first. And anything involving removing a covering, which belongs in the restoration cost calculator instead.
