Our Story

Mammoth Janitorial is a locally owned commercial cleaning company based in Reno, NV, backed by more than 30 years of experience in the janitorial industry. After decades in the field, we launched Mammoth Janitorial with a simple goal in mind: give businesses a cleaning partner they never have to worry about.

We know what separates a good janitorial service from a forgettable one. It comes down to showing up, paying attention to the details other crews miss, and communicating clearly when something needs attention. That's the standard we built Mammoth Janitorial on.

We clean offices, commercial buildings, and medical and professional suites on a schedule that works for you, whether it is nightly, weekly or monthly. Our services cover routine janitorial work, restrooms and break rooms, hard-surface floor care and carpet cleaning, and commercial move-in/move-out cleaning.
