Deep scratches are different from an uneven floor
A scratch is damage within the stone surface; lippage is a height difference between neighboring tiles. Both may lead to a grinding assessment, but their causes and limits are different. A worn traffic lane can sometimes be refined without leveling every tile. Conversely, polishing a raised edge does not necessarily change the height difference. Describe where you feel or see the problem and whether it has changed over time, so the assessment can address the actual condition rather than only the shine.
Grinding cannot create sound support beneath an unstable installation. Tile movement, excessive height differences, very thin stone, and vulnerable borders can change the recommendation. Ask which areas can be included and which may need an installer or another trade first. An estimate should distinguish open-floor work from detailed edge treatment and explain the desired honed or polished finish. Removing more material is not automatically a better result; the suitable amount depends on the installation and the damage.
