Using proven techniques and quality equipment, our team completes your window cleaning efficiently while maintaining a high standard of detail, care, and consistent results.
We review the work carefully to ensure everything meets our standard, leaving your windows spotless and your property clean, refreshed, and looking its best.
When you book a window cleaning with Sierra Services, our team arrives on time with all the equipment needed to leave your windows spotless. We clean both the interior and exterior of every window, including frames, sills, and tracks. Screens are carefully removed, cleaned, and reinstalled at no extra charge.
We use a specially formulated, biodegradable cleaning solution that cuts through Whistler's unique mix of pine sap, mineral deposits, and mountain dust without leaving streaks or residue. For multi-storey properties, we use professional water-fed pole systems that reach up to four storeys safely from the ground.
Whether you have a compact townhouse in Whistler Village or a sprawling estate in Kadenwood, we tailor our approach to your property. Most residential jobs are completed in 2-4 hours, and we always do a final walkthrough with you to ensure every pane meets our standard.
Whistler's mountain environment is tough on glass. Heavy snowfall leaves mineral deposits when it melts, pine pollen coats surfaces in spring, and wood-burning fireplaces create a film of soot during winter. Regular professional cleaning — ideally twice a year — prevents permanent etching and keeps your views crystal clear. Many of our clients in Squamish and Pemberton schedule spring and fall cleanings to stay ahead of seasonal buildup.
We recommend at least twice a year — once in spring after the snow melts and again in fall before winter sets in. Properties near construction sites, busy roads, or surrounded by pine trees may benefit from quarterly cleaning.
Yes. We clean windows year-round in Whistler, Squamish, and Pemberton. In winter, we use heated purified water systems and adjust our scheduling around weather windows to ensure safe, streak-free results.
