Commercial Window Cleaning Services in Denver, CO

Commercial window cleaning is priced per pane. On a recurring schedule, windows are $8 a pane inside and out, or $5 a pane exterior only. A one-time clean, or the first visit of a recurring account, is $14 a pane inside and out, or $7 a pane exterior only, because the first clean takes the longest. A small office building with 40 panes on a recurring schedule comes to about $320 a visit inside and out, or $200 exterior only. Paint-covered or construction glass is quoted per job, and high-rise windows are quoted per building. Your exact price is confirmed after a free walkthrough.

Office buildings in standard environments should have windows cleaned at minimum quarterly (4 times per year)—more frequently for ground-floor and high-visibility areas. Retail storefronts in high-traffic areas benefit from bi-weekly or weekly cleaning to maintain customer-attracting curb appeal. High-rise buildings typically schedule 2–4 cleanings annually, with more frequent service for lower, street-facing floors exposed to dust and traffic film.

Yes, we provide comprehensive interior and exterior window cleaning services. Our interior service includes screen cleaning, window frame wiping, and sill dusting. When scheduling interior work, we coordinate with your team to minimize disruption to employees and customers—often cleaning during early morning hours, evenings, or weekends based on your preference.

For buildings over four stories, access is by rope descent, boom lift or scaffolding, depending on the building and what it takes to reach every window safely. High-rise work is scoped and quoted per building rather than per window. Crews use rope descent systems secured with double-anchored safety lines. When roof anchors aren't available, we coordinate boom lift or scaffolding access. Certificates of insurance are available on request.

Yes, we clean windows in temperatures as low as 20°F using specialized cold-weather solutions formulated to prevent freezing on glass. We avoid cleaning during heavy rain, snow, or high winds for both safety and quality reasons—water drops and wind-carried debris prevent streak-free results. Our scheduling team monitors forecasts and reschedules when conditions aren't suitable.
