Serving Northglenn businesses with:
A compact, close-knit business community along the I-25 corridor — our Northglenn crew works with property owners and managers who often know their tenants personally.
Local Knowledge
A smaller market where relationships still matter.
Northglenn is one of the more compact cities in the metro, with most commercial activity concentrated along the I-25 corridor and around the Northglenn Marketplace retail area. It's a market with a lot of long-tenured local businesses and property owners who know their tenants by name — not a place where you want a cleaning crew that treats every account like a number.
Because it's smaller, Northglenn businesses often don't get the same attention from larger regional cleaning companies that prioritize bigger downtown accounts. We treat a small retail strip or a single-suite office here with the same standard we bring to a multi-floor building in Denver.
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 Northglenn
Trusted across every kind of facility.
Small retail strips, single-suite offices, and long-established local businesses — we bring the same crew standard here as anywhere else on our service map.
Why Northglenn 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 Northglenn 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.
