Frequently Asked Questions
Everything you need to know about our window cleaning process, safety standards, and pricing.
Our multi-stage Reverse Osmosis and Deionization (RO/DI) filtration system removes 100% of dissolved minerals, calcium, and salts from Montreal tap water, reaching a certified 000 PPM purity. Because pure water is naturally unstable, it actively attracts dirt particles off the glass like a magnet. When rinsed, it evaporates completely spot-free without squeegeeing and leaves no chemical residue, meaning your windows stay cleaner significantly longer.
Yes, absolutely. The Montreal Window Cleaners carries a comprehensive $5,000,000 Commercial General Liability Insurance policy that protects your residential or commercial property against any accidental damage. Furthermore, our entire staff is covered by Quebec’s CNESST workplace safety board and certified in ladder safety and working at heights.
Pure clean rain does not make clean windows dirty; rain only spots glass when dirt and dust are already present on the pane or frames. However, for complete peace of mind, we provide a 48-Hour Weather Guarantee: if rain or storm conditions spot your windows within 48 hours of service, simply call us and our crew will return to touch up the affected exterior panes free of charge.
For residential properties in Greater Montreal, we recommend at least twice a year: once in early spring to eliminate winter salt spray and grime, and once in autumn combined with gutter clearing. For high-traffic commercial storefronts and restaurants, bi-weekly or monthly maintenance keeps your business looking sharp and inviting.
