Concrete polishing and resurfacing covers two related but distinct jobs. Polishing grinds down an existing slab in stages, using progressively finer diamond-impregnated pads, then densifies the surface with a chemical hardener to produce a smooth, glossy, low-maintenance floor. It works on slabs that are structurally sound but worn, dull, or stained. Resurfacing is used when the existing concrete has cracks, spalling, pitting, or uneven patches that grinding alone can't fix. A contractor applies a cementitious overlay or micro-topping to rebuild the surface before it's ground, sealed, or coated. Many jobs in Hamilton involve both: patching and leveling first, then polishing or coating over the repaired slab.
We list 6 businesses in this category. When comparing them, ask what grit sequence they run (a proper polish usually works through several steps, not two or three), whether they densify with lithium silicate or an older sodium/potassium hardener, and how they handle joints and cracks before topping. Get a look at a completed floor in person if you can, ideally one that's a few years old, since gloss and clarity fade faster on jobs that skipped steps. Ask about dust control too: dry grinding without a good vacuum shroud leaves silica dust everywhere.
Our ranked guide orders these 6 contractors by the scoring approach explained on our methodology page, weighing things like documented process, warranty terms, and project history. See the full breakdown at best epoxy flooring companies in Hamilton.
