237 janitorial services establishments are based in the Columbia metro. That is 15 fewer than a year ago. When a contractor closes or sells, its customers go looking for a new one. The trade is 46% more concentrated than the U.S. as a whole. Facility and office managers here already hear from commercial cleaning companies, and a specific reason to talk beats a generic pitch. 2.8 larger cleaning-buying buildings per contractor puts Columbia 87 of 100 markets, and 3 of 3 in South Carolina. That is toward the crowded end, so growth here comes mostly from displacing incumbents at renewal. If you can serve Charleston and Charlotte, they have more larger buildings per contractor than Columbia.
