Local Knowledge
Westminster sits on the US-36 corridor, and that shapes the work.
Westminster occupies a strategic spot between Denver and Boulder along the US-36 corridor, which has become one of the metro's real tech and office hubs — corporate campuses and mid-size office buildings line the highway, many run by regional or national companies with their own security and access standards. Retail is concentrated around the Orchard Town Center and the Westminster Promenade, drawing steady daytime and evening foot traffic that shapes when cleaning needs to happen without disrupting customers.
With Standley Lake and several large open-space parks nearby, Westminster also draws a fair amount of outdoor foot traffic into nearby retail and office space — more dirt and debris tracked in during warmer months than some other parts of the metro. We factor that into entryway and common-area attention through spring and summer.
Getting Started
Working around your building, not the other way around.
Every building comes with its own set of logistics — limited after-hours parking, badge or fob access, freight elevator scheduling, or a building management company that needs to sign off on vendor access before anyone sets foot inside. We handle that coordination as part of onboarding, not as your problem to solve. During your free walkthrough, we'll ask about your building's specific access requirements and build our crew's schedule around them, so cleaning happens on time without disrupting your tenants, your staff, or your building management relationship.
If you're switching from another provider, we also handle that transition directly with your outgoing vendor where possible, so there's no gap in coverage and no awkward overlap period. Most clients tell us the hardest part of switching cleaning companies is worrying about what falls through the cracks during the changeover — that's exactly what we manage so you don't have to think about it.
Who We Serve in Westminster
Trusted across every kind of facility.
Corporate offices along US-36, retail at the Promenade, or a smaller professional suite — we scale the crew size and schedule to the building.
Why Westminster Businesses Choose Us
Local ownership, our own crew, real accountability.
Jan-Stars is based right here in Commerce City, not a national franchise dispatching whoever's available that week. Every cleaner on your account is our own hand-selected employee — never a rotating cast of subcontractors you've never met and can't reliably reach. That matters more in a market like the Denver metro's, where a lot of commercial cleaning gets handled by out-of-state companies managing crews remotely. If something's off, you're calling a local business that answers, not a call center.
We've been doing this in the Denver metro since 2009 — long enough to have worked through building management turnovers, seasons of nearby construction, and every kind of after-hours access system a Westminster building tends to use. That history matters when something unexpected comes up, because it usually isn't the first time we've run into it.
