Commercial cleaning · Denver, Colorado

Facility cleaning, held to a higher line.

After-hours janitorial for offices, retail, warehouses and property managers across Denver and the surrounding cities. A standard you can set your compass by.

The Northline difference

Commercial cleaning built on accountability.

Most cleaning complaints come down to the same thing: no one checks the work. We start every account with a written standard for your building, then hold that line every visit with consistent crews, regular inspections and photos after each clean.

Local ownership. Clear standards. A partner who picks up the phone.

FAQ

Questions facility managers ask us.

How do you price commercial cleaning?

We visit your facility for a free walkthrough, estimate the labor hours your space needs at the frequency you want, and send a fixed monthly price. No surprise charges.

Do you clean after hours?

Yes. Most of our commercial cleaning happens in the evening or overnight so your team and customers are never interrupted.

How do I know the job was actually done?

After every clean, your crew completes your building's checklist and sends you photos of the key areas. If something is missed, we come back and fix it.

What are your contract terms?

Standard agreements run 12 months with a 30-day cancellation clause, so you're never stuck with service you're not happy with.

Do you supply products and equipment?

Yes. We bring all equipment and cleaning products. Restroom consumables (paper, soap, liners) can be supplied by us or by you.

What if I'm not satisfied?

Tell us within 24 hours and we'll re-clean the area at no charge. That's our satisfaction guarantee.
