Why do you offer Tri-weekly service when none of your competitors seem to?

Frankly, we are surprised. Weekly to bi-weekly is a double time interval, just as bi-weekly to monthly is. We can understand the rationale in how it may sound to our customers however from a cleaning perspective cleaning every three weeks means less accumulation of dirt, dust, and pet hair than cleaning once a month. Our discount structure favors cleaning every three weeks over the discount provided for monthly service.
