FREQUENTLY ASKED QUESTIONS
Can hard water stains be completely removed from windows?
In most cases, yes. Our specialized treatment process can remove even severe hard water staining and mineral deposits. The success depends on the stain's age, severity, and glass condition. During our assessment, we'll evaluate your specific situation and provide realistic expectations for restoration results.
How often should commercial windows be professionally cleaned?
Most commercial properties benefit from quarterly window cleaning, while high-traffic locations like restaurants and retail stores often opt for monthly service. Environmental factors like construction, coastal location, or irrigation systems may necessitate more frequent cleaning. We can recommend an appropriate maintenance schedule based on your specific conditions.
Do you work on multi-story buildings?
Yes, our technicians are trained and equipped to safely clean windows at height. We utilize water-fed pole systems, lifts, and other professional equipment to access upper stories.
Will window cleaning disrupt our business operations?
We understand the importance of minimizing disruption. Our team can work during off-hours, early mornings, or weekends to accommodate your schedule. For retail and restaurant locations, we often schedule services before opening or section-by-section to maintain business continuity.
