Our story
Built on Hard Work, Built for Reno
Mammoth Janitorial was founded right here in Reno, NV with one goal: deliver cleaning services so thorough, our clients never have to think about it again.
Our History
Over the years we've grown into a full-service janitorial company serving hundreds of clients across the greater Reno-Sparks area. But our values haven't changed: show up on time, do the work thoroughly, and treat every space like it's our own.
Today our team of bonded, background-checked professionals handles everything from daily office maintenance to move-in/move-out deep cleans — always with the same attention to detail that built our reputation.
What We Stand For
Reliability
We show up when we say we will, every single time. Your schedule matters and we respect it.
Thoroughness
We don't cut corners. Every job gets our full attention from start to finish.
Trust
Every crew member is background-checked, bonded, and insured. Your property is safe with us.
Locally Rooted
We live and work in Reno. Supporting our community isn't a tagline — it's how we operate.
