Interior & Exterior Window Cleaning

Crystal-clear windows that let your business shine — from ground-level storefronts to multi-story commercial buildings.

About This Service

Clean windows transform the look of any commercial space. R&J Janitorial provides thorough interior and exterior window cleaning for offices, storefronts, industrial buildings, and multi-story facilities across the Hamilton area.

Our teams use professional-grade squeegees, water-fed pole systems, and eco-friendly cleaning solutions to deliver streak-free results on every pane. For multi-story buildings, we deploy water-fed pole technology that reaches up to four stories from ground level — no ladders or scaffolding required for most jobs.

Regular window cleaning isn't just about appearance. Mineral deposits, hard water stains, and environmental contaminants etch glass over time, causing permanent damage. Scheduled cleaning protects your glass investment and maintains clear sightlines.

Frequently Asked Questions

How often should commercial windows be cleaned?

Most businesses benefit from quarterly cleaning, though storefronts and high-visibility buildings may need monthly service. We'll recommend a schedule based on your location and needs.

Can you clean windows on multi-story buildings?

Yes. Our water-fed pole systems reach up to four stories from ground level. For taller buildings, we coordinate with certified rope-access or lift operators.

Do you clean in cold weather?

We clean year-round. In winter, we use cold-weather solutions that prevent freezing and still deliver streak-free results.

Is there anything I need to prepare before your team arrives?

For interior cleaning, we ask that items be moved away from windowsills. For exteriors, please ensure access points are clear. We handle everything else.
