Window Cleaning Services

Residential Window Cleaning

We charge a starting rate of $6 for each window pane, with a minimum charge of $150, including the inside and outside surfaces, without regard to size or travel costs. As part of our residential cleaning service, we will clean your screens and wipe off all tracks and sills. For an extra charge, we can also remove hard water, remove paint and clean skylights.

Commercial Window Cleaning

For commercial windows, we charge a starting rate of $3 per pane, which includes the inside and outside surfaces in addition to wiping of the sills and travel fees. We do charge a minimum of $100 for commercial window cleaning jobs and do charge extra for paint and hard water removal, skylight cleaning and 3rd story glass cleaning. High rise and other large commercial buildings are bid on site.

Post Construction Cleaning

Construction projects can leave your windows extremely dirty, not to mention that construction clean up is a very delicate process. Starting at $10 a pane, we will carefully check and clean every window with extra caution to avoid scratches. The service includes screen cleaning, track and sill cleaning and ladder work.

Frequently Asked Questions


Finding a time during the work week can be a challenge so we do not require you to be present. We just need to know which surfaces you want cleaned (basement and/or garage), how to gain access to the inside (our clients often leave a key in a secret location), and where to leave the invoice. We are happy to work with any specific instructions that you have for us.


We understand that plans change so we ask that you give us at least 48 hours notice on all non-emergent cancellations that way we can fill the time gap.


We reschedule appointments for 3 reasons; 1) active precipitation, 2) the high temperature for the day is below 37 degrees, and 3) wind gusts above 50 mph. Generally we try to wait until the morning of the cleaning before making any changes to the schedule. Having closely watched Denver weather for many years, we’ve seen plenty of rainy forecasts turn to beautiful sunny days so we are hesitant to reschedule on the basis of a 7 day forecast. On a day when it is necessary to reschedule we do our very best to inform you before 8:30am.

Winter Window Cleaning: We clean through all seasons so long as it is not precipitating and the forecast calls for a high temperature above 40 degrees.


Residential = $3.00 per pane. Commercial = $1.50 per pane. Post-construction = $5 per pane (these are all starting base rates)
