Why Professional Window Cleaning Matters

Windows impact your facility in ways that transcend aesthetics.

Natural light quality

Dirty windows can reduce natural light penetration by 20-40%. Clean glass maximizes daylight, reducing artificial lighting needs and improving occupant wellbeing.

Building appearance

Exterior windows are your building's first impression. Spotted, streaked glass suggests deferred maintenance throughout the facility—regardless of what's actually happening inside.

Window longevity

Environmental contaminants, hard water deposits, and oxidation gradually damage glass surfaces. Regular professional cleaning removes these before permanent etching occurs.

HVAC efficiency

Dirty windows can reduce solar heat gain in winter (increasing heating costs) and may absorb more heat in summer, affecting cooling loads.

Pure Water Technology Explained

Traditional window cleaning uses squeegees with chemical cleaning solutions. This works, but leaves microscopic residue that attracts dust and dirt, meaning windows soil faster after cleaning. Pure water cleaning is different.

1

Multi-stage filtration

Water is filtered through multiple stages of deionization and reverse osmosis, removing all minerals and contaminants. The result is water that's "hungry" to absorb impurities.

2

Active cleaning

When this ultra-pure water contacts dirty glass, it aggressively bonds with contaminants—dirt, dust, hard water deposits, environmental pollutants. The water does the cleaning work.

3

Residue-free drying

After scrubbing with water-fed brushes, pure water rinses the glass completely. Because there are no minerals in the water, it evaporates without leaving any residue behind.

The result: Streak-free glass that stays clean longer because there's no chemical residue attracting new soil.

Frequently Asked Questions

What is pure water technology and why is it better?+
Traditional window cleaning uses squeegees with chemical solutions that leave microscopic residue attracting dust and dirt. Pure water cleaning uses water filtered through deionization and reverse osmosis, removing all minerals. This ultra-pure water bonds aggressively with contaminants and evaporates without leaving residue—resulting in streak-free glass that stays clean longer.
How high can you reach without aerial lifts?+
Our water-fed pole systems can reach windows up to 60+ feet from ground level. This covers most 4-5 story buildings without requiring ladders or aerial lifts, reducing setup time, disruption, and safety exposure.
Do you clean both interior and exterior windows?+
Yes. Interior service covers all accessible glass including conference rooms, partition glass, vestibules, and restroom mirrors. Exterior service covers ground-accessible windows through water-fed poles and, when needed, aerial lift access for high-rise buildings.
Can you provide certificates of insurance?+
Absolutely. We carry comprehensive liability insurance and workers' compensation coverage appropriate for commercial work. We can provide certificates naming your organization as additionally insured upon contract execution.
What if weather prevents exterior cleaning on the scheduled day?+
Exterior work is weather-dependent. We monitor forecasts and will reschedule if conditions will compromise results—rain, high winds, or freezing temperatures can affect quality. We coordinate with you to find the next available window.
