What We Clean: Windows Inside & Out
Clean windows help your building stand out and create a brighter, more welcoming space. Whether you need service for a busy lobby, upper-floor offices, or exterior-facing glass, we’re equipped to handle it.
Our window cleaning services include:
- Interior glass (offices, lobbies, conference rooms)
- Exterior windows (low- and mid-rise buildings)
- High-access windows with professional safety equipment
- Removal of hard water stains, mineral buildup, paint, or adhesives
- Wiping of sills and frames (available upon request)
We use commercial-grade tools and proven methods to deliver clean, professional-looking windows, without disrupting your business.
Commercial-Focused Service
We work with a wide range of industries, including education, healthcare, banking, and municipal properties. Whether you need a one-time clean before an event or ongoing service for a large facility, we’ll build a plan around your building’s specific layout, usage, and cleaning needs.
Our team is familiar with the regional challenges in Eastern Washington; spring dust, rain spots, and more, and will suggest a maintenance schedule that keeps your property looking sharp without unnecessary visits.
One Team for Multiple Services
Many clients who hire us for window cleaning also rely on us for other janitorial needs. Because we handle all commercial cleaning in-house, it’s easier to streamline scheduling and simplify communication, no need to juggle multiple vendors. Whether it’s janitorial service, pressure washing, post-construction cleanup, or floor care and maintenance, bundling services with one trusted provider helps reduce downtime and keeps your entire facility looking consistent.
