We believe that a respected staff of cleaners is essential to the consistent delivery of high-quality janitorial services and measurable change for our clients. We’re dedicated to building a trusted, professional cleaning staff and to do so, we cultivate an environment where our employees can thrive and grow. Through fair compensation, training and development, we empower our staff to achieve the highest levels of professionalism and success. We not only care about clean, but we care about our people too.


GSF USA is a sustainable company, and our sustainability begins with our Research and Development department. Composed of microbiologists, pharmacists, medical engineers, quality engineers, time and motion engineers, and industrial engineers, our R&D; team creates best-in-class cleaning processes that maximize efficiency and cleaning quality.

Our R&D; team also tests techniques and chemicals on site in our “clean room” allowing them to recommend equipment and chemicals for the entire company based on efficiency, safety, and environmental friendliness.





GSF USA uses the latest technological tools to ensure smooth workflow, consistent quality control and a high level of client satisfaction. Our customized scheduling and workloading software allow us to quickly fill open shifts, thus avoiding unnecessary idle time. In addition, our software also allows us to monitor productivity, and to put together competitive and transparent bids for our potential clients. We synchronize our software with time-tracking, communication, and quality control tools, as well as tools that aid various supervisory tasks, providing the greatest level of consistency and accountability



GSF USA strives to use the most advanced equipment whenever possible, minimizing excess noise and maximizing filtration levels and air quality. Our equipment meets requirements for LEED-certified buildings, and GSF purchases are approved by our R&D department after rigorous testing for performance prior to use in our client’s buildings. Each piece is selected based on the individual needs of each site, ensuring productive, efficient cleaning. GSF’s equipment must:

  • Ensure high efficiency and productivity
  • Be environmentally friendly and meet best industry standards
  • Operate safely for our operators as well as customers
  • Be certified by the appropriate and recognized institute


Through our maintenance program, we repair or replace malfunctioning equipment ensuring its safety, efficiency and green cleaning capabilities. Maintenance logs are kept at each site, ensuring that each piece of GSF equipment is in perfect working condition

GSF’s choices in equipment are:

  • ProTeam SuperCoach Vac
  • Windsor Sensor XP
  • Tennant T3 Walk Behinds
  • Tennant Floor Machines
  • Bissell Big Green Commercial Extractor BG10
  • Tennant Wide Area Vacuum
  • Taski Swingo 150E
  • Taski Automatic Scrubber



At GSF USA, we are committed to the communities we serve by providing professional cleaning services and by finding opportunities to share our passion for what we do. We reach out to communities in an attempt to find people with exceptional talent and dedication, and offer them a way to become part of our team of experts. By regularly holding recruiting events in communities that otherwise have scarce access to job resources, we are able to empower people and put them on a track to pursue promising careers. We are most proud when our recruits achieve personal success, and make a positive impact on their own immediate environment.


Each of our service offerings is regularly reviewed and adjusted to meet the highest standards of environmentally-friendly practices. We use the best available technology to maximize efficiency, and best-in-class high- tech equipment to reduce waste. In addition, our cleaning chemicals go through rigorous evaluation by our research and development team to ensure that they are safe for employees as well as for our clients.



Daytime cleaning services are often much more efficient and sustainable than cleaning during the evenings. Expansive and heavily-used areas accumulate dirt quickly, and less frequent cleaning can easily create an unhealthy and unsafe working environment. Plus, cleaning during the day while a property is already in use, can bring tremendous energy savings.



At GSF USA, we have rigorous quality control measures in place to ensure that when we select, purchase and use our cleaning substances, we remain efficient, cost-effective and adhere to the most progressive environmental standards. We share our thorough understanding of materials and how to best procure them with our clients, allowing them to rely on our expertise when restocking supplies like towels, soap and paper products.

GSF USA staff participate in the Coalition for Construction Safety (CCS) Certification Program. Various members of our team either hold the Occupational Safety and Health Administration (OSHA) 30-hour Certification or the OSHA 10-hour Certification, and we also have a Fall Protection Certified Trainer on our GSF USA Management Team.
