Concrete polishing and resurfacing covers two different repair paths that often get lumped together. Polishing grinds down an existing slab in stages, using progressively finer diamond tooling, to expose a smooth, dense surface that can be left as a satin or high-gloss finish. Resurfacing is different: it applies a new cementitious or polymer-modified topping over a slab that's cracked, pitted, spalled, or uneven, effectively giving you a fresh wearing layer instead of a full tear-out and repour. Garages, basements, warehouses, retail floors, and patios all show up as common jobs for Mississauga contractors in this category, and a lot of the work overlaps with epoxy and polyaspartic coatings once the concrete itself is prepped and sound.
We list 24 businesses doing this work across the city, ranging from small crews that focus on residential garages and basements to larger operations set up for commercial and industrial floors. Before hiring, ask what grinding equipment they run (dust-collection matters, both for cleanup and for air quality during the job), whether they test moisture and slab hardness before quoting a fix, and how they handle cracks or joints so they don't telegraph through a new topping. Get a clear answer on cure times and when the floor can take foot or vehicle traffic.
Our scores weigh licensing, warranty terms, project photos, and verified customer feedback so you're not guessing. For the full ranked breakdown, see our best epoxy flooring companies in Mississauga guide, and check how we score and rank contractors for the details behind the list.
