Frequently asked questions
How much does commercial cleaning cost in Seattle?
A 10,000 square foot office cleaned five nights a week typically runs $2,850 to $3,450 a month in Seattle, based on the local median janitor wage of $22.35 an hour. Medical offices and gyms cost more per square foot, and churches and warehouses cost less.
Is janitorial service the same as commercial cleaning?
Mostly. Janitorial service usually means the routine cleaning done every visit: trash, restrooms, dusting and floors. Commercial cleaning also covers periodic and specialty work such as floor refinishing, carpet extraction and window washing. Most commercial cleaning companies in Seattle do both.
