"Used Crystal Clear after 3 different companies couldn't get hard water spots off our skylights. They restored them with cerium oxide polishing in one visit. $600 well spent."

FAQ

Common questions about commercial window cleaning

How often should I clean my windows?
Most Seattle homes do 2-3 times per year: spring (after pollen), mid-summer (after window-fly season), late fall (before holiday entertaining). Coastal homes benefit from a 4th cleaning.
Will rain re-streak my freshly cleaned windows?
No — properly cleaned glass with rinse-aid finish doesn't streak from rain. Even Seattle rain. If you're seeing streaks after rain, the wipe job wasn't done properly.
Do I need to be home?
Not for exterior-only work. For interior service we need access — most customers leave a key or have us schedule when you're home.
What about my screens?
We remove all screens, clean them with mild detergent, dry them, and reinstall. Screens often hold pollen and dirt that re-coats windows within days.
Are you insured?
Yes — $2M general liability plus full workers comp on every employee. Important for any work where ladders or lifts are involved.
