About Us In Fort Collins
Matt is a Fort Collins teacher who built Clean as a Whistle around the way he'd want his own home treated. He lives here, shops here, and cleans windows here — so when you book, you get the owner at your door, on time, with a plan for your glass.
Fort Collins glass takes a beating: sprinkler overspray leaves mineral spotting on ground-floor panes, spring winds blow dust and cottonwood off the Poudre corridor, and hail season leaves grit in every track. We work window by window instead of blasting through a route, so you actually see the difference from the inside.
