Our Methods
One of the things that truly sets Spectrum apart from other janitorial companies is our ability to take on the toughest jobs and do so quickly and to a high level thanks to our extensive, cutting-edge technology. We are a CIMS Certified janitorial company, demonstrating our commitment to maintaining hygienic environments that benefit building occupants through strict management and attention to detail.
We maintain this standard by utilizing the latest technology, including robotic cleaning tools, electrostatic disinfecting, and so much more. We do so much more than just vacuum carpets and mop tile—we are capable of providing a deep and thorough level of regular cleaning that protects your workforce and preserves your environment long-term.
A member of our team will be in touch shortly to confirm your contact details or address questions you may have.
Our Team
What makes for a high-quality cleaning company? The answer is simple: the people who provide the service. At Spectrum, we recognize that we must attract, hire, train, motivate, and retain the best staff in order to provide the elite level of services our customers have come to expect and demand from us. That means hiring people who are more than just cleaners—they also care about the cleanliness, security, and well-being of your facility.
Our first step in doing so was to create a culture that values the employees who are delivering your service. Employees who feel valued, respected, and rewarded for going above and beyond will consistently deliver better service over time. That’s why this philosophy is engrained in our company culture, from how we hire to how we conduct ourselves each and every day.
- We screen for the best. All of our employees undergo extensive screening for honesty, integrity, and pride in what they do. That means a full background check and a thorough interview process.
- We equip our team. Our crew can only be their best if we equip them as such. That means providing thorough training and cutting-edge tools.
- We reward excellence. Our staff is rewarded when they serve our customers with excellence. Every team member is incentivized to help our company perform well and earn the satisfaction of every client.
- We follow up. Our customers should be 100% satisfied with every service, so we follow up with you through tracking technology that allows you to actively manage how we serve your facility.
