1,055 janitorial services establishments are based in the Houston-Pasadena metro. That is 17 fewer than a year ago. When a contractor closes or sells, its customers go looking for a new one. The trade is at about the national concentration. 5.6 larger cleaning-buying buildings per contractor puts Houston 11 of 100 markets, and 3 of 6 in Texas. That is more room per contractor than most metros, so systematic prospecting tends to find accounts nobody is working. If you can serve McAllen, it has more larger buildings per contractor than Houston.
