How this list was built

We pulled Google Maps listings categorized as janitorial or commercial cleaning services within about 25 km of central Denver on October 22, 2026 (our data provider last refreshed these listings between September 11, 2026 and October 8, 2026). We kept businesses that were not marked closed, had at least 5 Google reviews and an average rating of 4.0 or higher, and dropped house-cleaning-only, carpet-only and pressure-washing businesses. The list is ordered by number of Google reviews. Ratings and review counts change daily, so check each company's current Google listing before you hire.

No company paid to be listed. If you run one of these businesses and something is wrong, the Google listing is the source; correct it there and it will update here on our next refresh.
