VCT, sealed concrete, vinyl plank, ceramic tile, natural stone and commercial carpet all want different products, equipment and frequencies. One approach across all of them is how finishes get damaged, months later and hard to attribute.
We identify every surface during the walkthrough and write the method for each into the scope. High-traffic corridors and entries need buffing far more often than back-of-house areas, so frequency is set by zone rather than by building.
The same logic applies to carpet. Scheduled hot water extraction removes the abrasive grit that cuts carpet fiber. Extraction only when carpet looks dirty means the damage already happened, and replacement costs an order of magnitude more than cleaning.
