Clean windows transform the look of any Ottawa home or business — letting in more natural light, improving curb appeal, and creating a brighter, more welcoming interior. But achieving truly streak-free, spotless windows requires more than a squeegee and a bucket of soapy water. Crystal Plus Ltd's professional window cleaning service in Ottawa uses professional-grade equipment, purified water systems, and proven techniques to clean every pane to a flawless finish — inside and out. We serve residential and commercial clients throughout Ottawa, Kanata, Nepean, Barrhaven, Gloucester, Stittsville, and surrounding communities. Our window cleaning team is trained to work safely at height, handle all window types, and clean frames, sills, and screens as part of every service. Ottawa's climate — with its freeze-thaw cycles, pollen seasons, and summer dust — means windows accumulate grime quickly. Regular professional window cleaning not only keeps your property looking its best but also extends the life of your window seals and frames by removing corrosive buildup. Crystal Plus Ltd has been Ottawa's trusted window cleaning provider for over a decade.
