About Us

Window Cleaning Professionals

Tom Walsh owns Zenith Window Cleaning and resides with his family in Firestone, CO. Tom has been cleaning windows for nearly 20 years. Zenith Window Cleaning is a unique window cleaning company that aims to be generous and contribute to our community and each other. On the outside, we are a quality window cleaning company serving the greater Denver area.

Behind the curtains, we are a family business to empower our team towards their dreams and passions. Through coaching, equipping, and developing, Tom builds up his crew members so that within two to three years, they are out launching their own business or career. We have helped build up individuals who are missionaries and owners of film/photography, film/branding/marketing, and more.
