One certification. Zero competition.
Most cleaning companies can't even get on a construction site. No OSHA 10-Hour certification means no access, plain and simple. Jani-King walks right in, fully cleared, while everyone else gets turned away.
Our Tulsa team got certified, partnered with JE Dunn Construction, and ended up becoming their exclusive cleaning provider. That one relationship turned into years of repeat business.
Why? Because we show up knowing PPE, safety documentation, and job site protocol inside and out.
"We are absolutely more safety aware, and we look like we know what we're doing when we walk on a job site." Dawn Arbo, Jani-King of Tulsa
This is what happens when you invest in the right credentials. Doors open, and they stay open.
