Commercial Cleaning & Post-Construction Services

Our Services

  • After-hours cleaning services for offices, fitness centers, and business facilities. We work while you're closed, so your team walks into a clean, professional space every morning. Systematic protocols ensure consistency across every visit.

  • Specialized cleaning for medical offices, chiropractic clinics, and healthcare facilities. We understand compliance requirements and use color-coded tools to prevent cross-contamination. HEPA filtration and medical-grade protocols protect your patients and staff.

  • Final cleaning services for commercial buildings, multi-family developments, and residential subdivisions. We handle the detail work that gets you from construction complete to move-in ready and certificate of occupancy.

Trusted by Seattle Businesses

Mark and his team do a great job with our chiropractic office. Always on time, very reliable, and they understand the cleaning standards we need for a medical facility. Would recommend.

Switched to Cascade Clean a few months ago and happy with the service. They're consistent, easy to work with, and pricing is fair. Mark is responsive if we need anything adjusted.

Used these guys for final cleaning on our new office building. They got us ready for certificate of occupancy on time and the work was thorough. Would hire again for future projects.
