We Graded 67 Denver Cleaning Services. Here's What We Found.
We ran every major Denver cleaning service through the GradeMyBiz scoring engine — Google reviews, website basics, response rates, and recency. The results were brutal. Only 11% earned an A. The bottom 40% had review scores so low they're effectively invisible in local search. The gap between the top and bottom wasn't quality of service — it was systems. The businesses winning on Google asked for reviews. The ones losing didn't.
