Commercial Window Cleaning
Interior and Exterior. Scheduled and Documented.
Commercial window cleaning is not just aesthetics. Dirty glass affects natural light levels, communicates a facility maintenance standard to visitors, and in some climates accelerates glass degradation from mineral deposits and oxidation. We provide interior and exterior window cleaning for office buildings, storefronts, and corporate campuses on a scheduled, documented program.
Commercial Window Cleaning services
Every service GPS-verified and tracked through our proprietary MillenniumOS platform. No more wondering if your crew showed up.
Exterior Window Cleaning
Ground-level and elevated exterior window cleaning using water-fed pole systems for mid-rise buildings and ladder access for lower floors. Pure water systems leave no residue or streaking. We access exterior glass safely without equipment that damages landscaping or facilities.
Interior Window Cleaning
Interior window, glass partition, and glass door cleaning using squeegee technique and commercial glass cleaner. We work around office furniture, equipment, and personnel without disrupting daily operations.
Storefront and Lobby Glass
High-frequency cleaning for storefront glass, lobby windows, and entry vestibules that accumulate fingerprints, smudging, and exterior soil quickly. Can be included in day porter scope for daily or multiple-times-weekly service.
High-Access Window Cleaning
Elevated window cleaning for multi-story buildings using water-fed telescoping poles that reach up to 60 feet without ladders. Pure water fed through carbon fiber poles and brush heads agitates and rinses glass in a single pass.
Glass Partition and Interior Glass
Conference room glass, office dividers, glass railings, and interior atrium glass. We clean both sides of all glass surfaces and address any hard water staining or film buildup from cleaning product residue.
Scheduled Window Cleaning Programs
We set a cleaning frequency based on your building type, location, and glass exposure. Urban storefronts may need weekly exterior cleaning. Corporate campuses with sheltered glass may need quarterly exterior and monthly interior service. Every visit is documented.
Why facilities choose Millennium
Window cleaning is one of the most visible indicators of a well-maintained facility. Visitors, clients, and employees form impressions from the building exterior before they enter. Yet most facilities treat window cleaning as an afterthought, calling for service only when complaints come in. A scheduled commercial window cleaning program keeps the building looking professional year-round, prevents mineral buildup that requires more aggressive treatment to remove, and extends glass life in high-UV climates like Georgia's.
Part of an Integrated Facility Program
Window cleaning is more effective when coordinated with the rest of your facility cleaning schedule. We integrate window service into your existing program so lobby glass gets cleaned before major events, exterior glass is addressed after storms, and you are not managing a separate vendor relationship for one service.
Proper Equipment for Every Building Type
Ground-floor storefronts and 40-foot atrium windows require different equipment and approach. We use water-fed pole systems for elevated exterior glass, squeegee technique for interior glass, and document the access method and products used for each area of your facility.
Scheduled, Not Reactive
Calling for window cleaning only when glass looks bad means mineral deposits have already started etching the surface. A scheduled program maintains glass in condition before buildup requires restoration treatment. We define frequency based on your exposure and track every visit.
GPS-Verified and Documented
Window cleaning visits are tracked through MillenniumOS the same as every other service we provide. GPS verification, crew assignment, time on-site, and areas completed are all logged. You have a documented cleaning history for every glass surface in your facility.

Industries we serve
Commercial Window Cleaning: FAQ
Common questions answered by our operations team.
Frequency depends on building location, exposure, and the impression standard required. Urban storefronts and high-traffic lobbies often need exterior cleaning weekly and interior cleaning biweekly. Corporate office buildings typically run monthly interior and quarterly exterior. Facilities in areas with high pollen, construction dust, or industrial fallout may need more frequent exterior service. We assess your specific building and recommend a schedule.
Yes. We use water-fed pole systems that reach up to 60 feet for exterior glass on mid-rise buildings. Pure water is fed through telescoping carbon fiber poles with brush heads that agitate and rinse glass in one pass without ladders. For buildings above that height, we coordinate with rope access or aerial lift specialists as part of the project scope.
Yes. Interior glass cleaning covers office dividers, conference room glass, glass doors, interior atrium windows, and glass railings. We work around furniture and active workspaces without disrupting operations. Interior glass is typically done during business hours for lobbies and common areas, and after hours for offices and conference rooms.
A water-fed pole is a telescoping pole, typically carbon fiber, with a brush head and pure water fed through the pole from a tank on the ground. The purified water has zero dissolved minerals, so when it dries on the glass it leaves no residue or streaks. No squeegeeing required at height, which is safer and faster for elevated exterior glass. We use this system for exterior windows above ladder access height.
Yes, in most cases. Light to moderate mineral deposits can be removed with mild acid treatment, mechanical agitation, or specialized glass restoration products. Severe etching that has penetrated the glass surface may require glass polishing or replacement. We assess the condition of the glass and recommend the appropriate treatment before starting.
Interior window cleaning in offices and conference rooms is typically scheduled for evenings or weekends when the space is clear. Lobby glass, storefront, and common area glass can be cleaned during business hours with crew working efficiently around foot traffic. We coordinate scheduling with your facilities team to minimize any disruption.
Interior lobby glass, storefront doors, and glass partitions are often included in a janitorial or day porter scope. Full interior window cleaning and exterior window cleaning programs are typically scoped separately and priced by the visit or on a scheduled contract. We can include window service in a comprehensive facility program or quote it as a standalone service.
We provide commercial window cleaning as part of integrated facility programs across metro Atlanta and statewide Georgia. This includes corporate campuses, entertainment venues, storefronts, and office buildings. Window cleaning is part of our broader facility services operation, not a standalone trade contractor business.
Yes. If you are already on a Millennium facility cleaning program, window cleaning can be added to your scope at any time. We schedule a walkthrough to assess all glass surfaces, define frequency for each area, and add it to your program with documented scheduling through MillenniumOS.
