Crystal-clear residential, commercial, and post-construction window cleaning across Kalispell — fast quotes, fair prices, and a job done the way you'd do it yourself.
From the older homes around Main Street to the new builds out toward Lone Pine and Buffalo Hill, Kalispell windows take a beating from blowing dust, sap from cottonwoods, and the harsh glare off snowpack in spring. We clean every pane inside and out, then polish the frames, sills, and tracks so you don't see streaks the moment the morning sun comes through.
OCS LLC is locally owned and operated by Barrett Teeney. We're licensed, insured, and we show up when we say we will. No call centers, no contractor relays — you talk to the same person who's going to be on your ladder. Most Kalispell estimates come back the same day, and we typically schedule one to two weeks out depending on the season.
