Window cleaning across the entire Flathead Valley

Local cleaning, done right

Kalispell sits at the heart of the Flathead Valley with the busiest mix of homes, businesses, and new construction. Properties here range from older homes around Main Street to new builds out toward Lone Pine, Whitefish Stage, and the airport corridor. 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.

What we do for Kalispell customers

• Residential window cleaning — interior, exterior, screens, and tracks
• Post-construction cleaning — stucco splatter, paint overspray, and labels removed without scratching
• Commercial maintenance — storefronts, offices, and multi-story buildings on a recurring schedule
• Pressure washing — driveways, decks, siding, fences
• Hard-water stain inspection and treatment options
• Skylights, sun rooms, and awkward second-story access
