Seattle’s fast-paced business environment demands a cleaning partner that can keep up. Whether you operate a corporate headquarters overlooking Elliott Bay, a medical clinic on Capitol Hill, or a coworking space in Pioneer Square, our team of 130+ trained professionals delivers consistent, reliable results. We understand that Seattle’s commercial spaces range from historic brick-and-timber buildings in the International District to modern glass towers along the waterfront, and we tailor our approach to match every environment.

Why Seattle Businesses Choose FCBM

Our deep experience in the Pacific Northwest means we understand the unique challenges Seattle buildings face. The region’s damp climate requires proactive attention to floor care, entryway maintenance, and moisture management. Our green cleaning program uses environmentally responsible products and practices that align with Seattle’s sustainability values, helping your business maintain LEED certification and meet the expectations of environmentally conscious tenants and employees.

We provide day porter services for busy lobbies, shared amenity spaces, and high-traffic common areas in Seattle’s premier commercial properties. From the office towers along 5th Avenue to the mixed-use developments in Belltown and Fremont, our daytime staff keeps facilities presentable and welcoming throughout the business day.

Comprehensive Janitorial Programs

FCBM’s janitorial programs for Seattle clients include nightly office cleaning, restroom sanitation, trash and recycling removal, and surface disinfection. We also offer specialized floor care services including hardwood refinishing, tile and grout restoration, and VCT stripping and waxing for lobbies, corridors, and common areas.

Window cleaning is another area where our Seattle teams excel. We maintain interior and exterior glass for multi-story commercial buildings, retail storefronts along Pike Place and University Village, and medical office windows that require streak-free clarity.

Serving Seattle’s Key Industries

Seattle is home to some of the world’s largest technology companies, a thriving healthcare sector anchored by institutions like the University of Washington Medical Center and Swedish Medical, and a growing life sciences corridor. FCBM serves clients across all of these sectors with cleaning programs designed to meet industry-specific standards, including healthcare-grade disinfection protocols and cleanroom-adjacent maintenance.

Our 25+ years of experience in the Pacific Northwest have taught us what Seattle businesses need: dependable crews, consistent quality, transparent communication, and a willingness to adapt.
