Window Cleaning


We use a streak-free pure water system to clean exterior windows, enabling us to reach up to 3 stories without leaving the ground. It's an eco-friendly process that allows us to get your windows sparkling clean quickly without sacrificing quality - that's the One Stop Guarantee!


Our clients love our window cleaning service program! With our automatic scheduling and reminder messages to keep you updated, you won't get any surprises; we will show on time. The benefit of using a pure water system is that we eliminated about 99 percent of streaking on the glass. It also preserves your window glass from being damaged.

Our XERO Screen Cleaner system washes screens quickly and can clean screens as large as a standard patio door screen. The brushes take care of the screen and frame all in one. With a built-in shut-off valve, it's eco-friendly.

Hard water

Hard water is full of minerals such as calcium, magnesium, metal cations, and compounds such as sulphates and bicarbonates. When it contacts glass, it can form water spots that are unsightly and hard to get rid of. These spots can also provoke irreparable damage to your windows if you don't get rid of them quickly.

Window track

Neglecting window tracks can build up dirt, grime and mold. It also can prevent windows from shutting properly, allowing drafts into the house. Regular maintenance and cleaning also prolong the lifespan of your windows sills, so long-term, you'll save money!

Window Cleaning & Janitorial Services


Headquartered in Fontana, California, our team offers service excellence using the latest innovations and technologies in the window cleaning industry.

It not only reduces the liability and risk of using boom lifts and suspension equipment, but it also allows us to clean the windows more thoroughly than the traditional method.
