Concrete Polishing Contractors in Connecticut— Rated & Reviewed
Polished concrete is ground and refined to create a hard, glossy surface without a topcoat. In Connecticut, it's popular for retail and commercial spaces that want a low-maintenance floor with a clean industrial look. Unlike coatings, polishing densifies the slab itself — there's nothing to peel or delaminate.

Concrete polishing costs $3–$15 per square foot. Basic honed finishes run $3–$7/sqft; high-gloss residential polishing $7–$12/sqft; and large commercial projects with economies of scale as low as $4–$6/sqft for 5,000+ sqft floors. Sealing and densifying adds $2–$4/sqft every 2–5 years.
- Finish level — honed (flat) vs. semi-polished (800 grit) vs. high-gloss (3,000 grit)
- Aggregate exposure — cream finish vs. salt-and-pepper vs. full aggregate exposure
- Concrete condition — existing cracks, coatings, or contamination add prep cost
- Square footage — large commercial projects reduce cost per sqft significantly
- Guard/sealer application — penetrating lithium silicate densifier is usually included
- Ongoing maintenance — periodic resealing or burnishing every 2–5 years
What to Ask Before Hiring
- Confirm they use planetary diamond grinders, not rotary buffer machines — the difference is significant
- Ask about the grit sequence they use (e.g., 30/50/100/200/400/800/1500/3000 grit for high-gloss)
- Verify they apply a lithium silicate or sodium silicate densifier — this hardens the surface and is not optional
- Ask about their crack and joint treatment process before polishing
- Check if they use wet or dry polishing — both are valid; dry is faster but wet produces finer results
- Ask for photos of finished projects at the specific gloss level you want
