About Us

A private-owned operation

for commercial janitorial services

Across our 38 years in operation,
we keep developing & advancing

In an industry that’s often stuck to old ways, we’ve continuously advanced our cleaning service since starting in 1986. Our unique methods clean better, faster, and save resources over large areas. And for our quality assurance program, we let our cloud-based software enhance accountability, communication, and client satisfaction.


Our teams have been the cleaners behind 1.3 million sq. ft. of the Department of Transportation for 23 years, 1.4 million sq. ft. of the Constitution Center for 12 years, and more. And always committed to the long-term, we extend 90% of our contracts—a rate far above industry others.

Why we have a higher level of cleaning solutions

Serving Washington DC, Maryland, and Northern Virginia

Bringing cleaning practices unique to the industry

Coming from a background of hospital cleaning in the 70s and 80s, we’ve developed a unique cleaning procedure that rigorously prevents cross-contamination from different parts of the building—keeping your occupants their healthiest and safest.

Using industry-leading technology & automation

Doing away with antiquated mops, we use industry-leading micro scrubbers that clean significantly better—all while using 50% less chemical discharge and 70% less water. For efficiency and top notch results, we embrace every opportunity for automation.

Meeting contract specifications—and going beyond

While we consistently adhere to contract specifications, we never stop there. Contracts often neglect changes in traffic patterns, occupant density, and other variables—all which we go the extra mile for to keep your environments always sparkling clean.

Green Cleaning not for trends, but for total impact

Instead of the common practice of switching one traditional product for a green alternative, we seek to make a 360° impact. We reduce waste at buildings and landfills, save energy with team efforts, and clean efficiently with healthier products.

Always selecting the best equipment & supplies

As a privately-owned company, we’re never restricted by a predetermined supplies budget that is often inadequate. Using the best equipment and supplies is certainly an investment, but one that definitively yields you better hygiene and cleaning results.

Responsiveness to your changes. Offering the best prices

As an independent family-owned business, we are ready to rapidly respond to any changes that arise to ensure your spaces are cleaned without disruption. And with no bureaucracy in our operations, we carry over the cost-savings straight to our clients.

Our core is our loyal employees
& specialized Team Cleaning

At the heart of taking the best care of each facility is our employees—who uphold the high standards of service our clients know us for. In recruiting: we hire locally, select motivated team members, and provide highly specialized field training for efficiency and online e-learning for compliance.

In the operations: our unique Team Cleaning system of working one floor at a time (with workers completing specific tasks before a leader inspects, corrects, and moves to the next floor and finishing with a report) is what gives us speed and cleaning excellence.
