If you manage an office, clinic, nonprofit, or commercial workspace, one of the first questions you'll ask is: how much does commercial cleaning cost in Seattle?
Seattle is a high-cost market compared to many U.S. cities, and commercial cleaning prices vary depending on the size of the facility, service frequency, restroom usage, and type of space.
Quick Answer: Typical Price Ranges in Seattle
Most commercial cleaning services in Seattle are priced based on a combination of square footage, number of rooms and restrooms, cleaning frequency, facility type and usage level, and service timing (daytime or after hours).
Small Office (1,000–2,500 sq ft)
- Weekly cleaning: ~$250–$700/mo
- 2–3 times per week: ~$700–$1,800/mo
- Ideal for: small professional offices, startups, administrative spaces with moderate traffic
Medium Office (2,500–7,000 sq ft)
- 2–3 times per week: ~$1,200–$3,000/mo
- Daily cleaning for higher-traffic teams: ~$2,800–$6,000+/mo
- Ideal for: growing companies, office suites with multiple restrooms, businesses with regular meetings and visitors
Large or Multi-Use Facility (7,000+ sq ft)
- Daily service: ~$4,000–$10,000+/mo
- Day porter services are often added as an extra monthly cost
- Ideal for: high-traffic facilities, multi-use spaces, buildings with multiple restrooms, kitchens, and shared areas
Hourly Commercial Cleaning Rates in Seattle
Some commercial cleaning providers price by the hour, especially for smaller offices or specialized projects. In the Seattle market, commercial cleaning is generally priced around $65–$80 per hour (depending on scope, facility type, supplies, and schedule). For recurring service, most businesses receive a fixed monthly quote based on the expected cleaning time and frequency.
What Affects Commercial Cleaning Prices the Most
1. Cleaning Frequency (Biggest Factor)
Frequency often impacts price more than any other variable. The more frequent the service, the more consistent the results — but also the higher the monthly cost.
2. Number of Restrooms and Break Rooms
Restrooms are one of the most labor-intensive parts of any commercial cleaning scope. Price increases when the facility has multiple restrooms, high restroom usage, restrooms shared by tenants, and kitchens and break rooms with frequent daily use.
3. Office Layout and Room Types
Two offices with the same square footage can have very different prices depending on layout. Open floor plans are generally faster to clean; many small rooms increase time and detail work; conference rooms require presentation-focused cleaning; break rooms and reception areas often demand extra attention.
4. Facility Traffic and Usage
A quiet professional office generally costs less than a facility with a high volume of visitors, rotating training programs or events, shared public spaces, or multi-use rooms.
5. Service Timing
Many Seattle businesses prefer after-hours cleaning to avoid disruptions. Price can vary depending on whether the service happens early morning, in the evening, on weekends, or during business hours.
How to Reduce Commercial Cleaning Costs Without Sacrificing Quality
- Prioritize high-traffic areas
- Increase restroom cleaning frequency while reducing frequency in low-use rooms
- Schedule deep cleaning quarterly instead of monthly
- Clearly define what's included and what isn't

A defined scope keeps expectations clear and avoids overpaying for unnecessary tasks.
