Ive seen and read alot of really good stuff about this business, Im considering doing this myself in the near future as soon as I get everything down on equip., chemicals quotes etc..( All info. deeply appreciated)..But when you do these jobs, and all that grease hits the floor is the floor job included in your price, do you charge them for that or do you leave it with them??? Im sure to within reason you rinse. But now the floor needs done.. Just curious!!
