Our COVID-19 Pandemic Response

We were one of the first building maintenance companies in the US to be involved with the COVID-19 pandemic. Since then we have been providing pandemic responsive services to clients while following health and safety guidelines and practices, as well as compliance with relevant public health agencies.

Our practices include and are not limited to using an electrostatic sprayer with disinfecting solution to exposed areas, cleaning touchpoints in exposed areas, collaborating between your team and our team regarding people whom may have been exposed to COVID-19,  training our employees on best practices from public health agencies as we manage exposures to COVID-19 on a case-by-case basis to ensure our employees and your employees are safe and healthy, and more practices ensuring health and safety.

About Us

For 25+ years we serviced the Greater Seattle Area from humble beginnings to hundreds of employees, accounts, and satisfied customers, especially today as essential workers providing various cleaning services. ​Cascadian Building Maintenance was founded in 1994 by 2 owners whom decided to leverage their 20+ years of experience in building maintenance to start our company in Redmond, Washington. As the company rapidly expanded, a General Manager was hired to oversee the business as a business partner and co-owner. Later, an Operations Manager was hired to oversee the operations aspect of the business. Today our headquarters reside in Bellevue, Washington. With 50+ years of combined experience, along with hundreds of employees, our leaders made it possible for our company to be a competitor in the industry serving the Greater Seattle Area and beyond.

Our mission is to provide quality and consistent services, be an inspirational partner for our clients, form a premier, ethical, and value service business, sustain environment and support communities, and provide safe, respectful, supportive, and educated jobs to our employees.
