If you’re budgeting a concrete floor polishing in St. Louis, most projects run $1,586-$8,456, 6% above the $3,500 national average.

Easiest place to save: Choose Level 1-2 polish instead of Level 3-4 aggregate exposure - the visual difference is less dramatic than the price difference ($3-$6/sq ft vs $8-$18/sq ft)
In the Midwest (where St. Louis sits): Competitive market; polished concrete popular in industrial-to-residential conversions.
