Chicagoland's Premier Commercial Cleaning Company
Cortex Cleaning is based in Geneva, IL, and clean glass is usually the thing that gets noticed first. A streaked storefront or a smudged lobby door says something about a business before anyone walks through it.
Clean glass doesn’t take much effort to maintain once it’s on a schedule, but it falls apart fast without one. We handle both interior and exterior glass for offices, storefronts, and multi-story buildings, sized to whatever the property actually needs.
Ground-level and low-rise exteriors get cleaned with a water-fed pole system, purified water run through an extendable pole, which lifts dirt without leaving mineral streaks behind and doesn't require a ladder against the building.
Taller buildings need something different entirely: suspended equipment operated by technicians trained under OSHA fall-protection standards, since a water-fed pole simply can't reach a fourth-floor window safely.
Neither method is a downgrade from the other. They're built for different heights, and using the wrong one is either impractical or unsafe.
Plenty of window cleaning companies do windows and nothing else, which means a building often ends up managing a separate vendor just for glass on top of whoever handles the floors and the nightly cleaning.
Cortex Cleaning is a Geneva-based crew that handles window cleaning alongside janitorial service, carpet care, and floor maintenance, so a property manager isn’t juggling four different companies and four different invoices for what is, in the end, one building. More than 10 years in business, every crew fully insured and certified.

Same-Week Walkthrough
Interior cleaning covers glass, frames, and sills from the inside, on whatever recurring schedule fits the space.
Exterior cleaning depends on the building's height, using either the water-fed pole method for ground-level and low-rise work or suspended equipment for anything taller.
Frames and sills get wiped down along with the glass itself.
A spotless pane surrounded by a grimy frame doesn't actually look clean.
Talk to a real person about your window cleaning, your schedule, and the finish it needs.
