These are the 10 industries Abstrakt's SDRs call for cleaning work, with how many of each are in the Houston-Pasadena metro and who to ask for. Compared with the U.S. as a whole, Houston-Pasadena leans toward owner-occupied and owner-managed commercial buildings (2.01x), commercial property management firms (1.44x) and ambulatory health care: physician, dental, outpatient and urgent care (1.42x).

1,072 janitorial services establishments are based in the Houston-Pasadena metro. That is 30 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. 5.5 larger cleaning-buying buildings per contractor puts Houston 10 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.

Tier 1 covers manufacturing plants, ambulatory health care: physician, dental, outpatient and urgent care and senior living and skilled nursing with 50 or more people on site.
