About Bob Popp Building Services

Window Cleaning is  one of the things we do best 

Founded in 1975 and based in Denver, BPBS provides high-rise, mid-rise, and ground-level window cleaning services for commercial businesses across Colorado. Top Gun and BPBS have a long history of successful partnership, as the companies have collaborated on many projects, buildings and shared customers over the past 20+ years.

Stephanie White, President of Top Gun, commented, “We are excited to partner with the entire Bob Popp Building Services team and capitalize on the Company’s significant growth opportunities in the Colorado market. BPBS is the clear market leader in Colorado commercial window cleaning due to its deep industry expertise, customer-first business model, and outstanding reputation. Combining Top Gun and BPBS, who together have 73 years of operating experience in the Rocky Mountain region, reinforces our commitment to delivering quality, environmentally-friendly services and provides us with the resources and support to continue to grow our business.”

Ben Moe, a Managing Partner at Osceola Capital, added, “The acquisition of BPBS is consistent with Top Gun’s growth strategy of building a leading provider of facilities services in the Rockies and nationwide through the acquisition of strong regional players that complement our existing portfolio of services. The addition of BPBS solidifies our core offering of pressure washing, window washing, power sweeping, and snow removal services, and we look forward to continuing to expand our geographic footprint and service suite.”
