A clean workspace changes everything. It’s not just about looks; it actually affects how people feel and work every day. From my experience handling office moves and cleanups, even a messy breakroom or dusty desk can make a place feel off.
In Denver, there are plenty of janitorial services, but the real challenge is finding one that shows up on time and actually does the job right.
Whether it’s a small shop or a busy office building, the right cleaning team makes a big difference. Let’s take a closer look at the best janitorial services in Denver available.
How much does a janitorial service cost in Denver?
In our city, professional cleaning services usually run between $0.10 and $0.30 per square foot. Specific pricing often depends on how often the crew visits and the unique layout of your facility.
| Service Type | Estimated Rate |
| Per Square Foot | $0.10 – $0.30 |
| Hourly Rate (Per Cleaner) | $35 – $80 |
| 10,000 sq. ft. Office (Monthly) | $2,000 – $4,000+ |
| Specialized Disinfection | Varies by facility |
1. JAN-PRO Cleaning & Disinfecting in Colorado

Website: https://jan-pro.com/denver/
Address: 1720 S Bellaire St.
Contact: +1 720-740-4720
Hours: Monday–Friday: 8:00 AM – 5:00 PM
Walking into a truly clean office changes the whole mood of a space. JAN-PRO Cleaning & Disinfecting in Colorado delivers exactly that feeling.
What stood out to me was their use of the EnviroShield® system, which sprays disinfectant to evenly coat surfaces rather than relying solely on manual wiping.
I also noticed how organized their cleaning flow is, especially in busy places like gyms, where hygiene really matters. Their color-coded cloth system is a small detail, but it prevents cross-contamination between restrooms, desks, and shared areas.
Staff training is another strong point. Their cleaners undergo a structured certification program before handling jobs.
The only downside is that service consistency can vary slightly because of their franchise model. Pricing can also feel higher compared to smaller local crews, especially for basic cleaning needs.
One of the more professional cleaning services
One of the more professional cleaning services we have used! We have a pretty large campus, and the ability to choose what rooms and the flexibility of when we would like things done has been awesome. We know what to expect and when to expect it. Our cleaners (Maria) are also super on top of communication and have responded within reason to our inquiries.

2. Corvus Janitorial Systems

Website: https://corvusjanitorial.com/
Address: 2020 S Oneida St.
Contact: +1 720-287-2964
Hours: Monday–Friday: 8:00 AM – 5:00 PM
It’s easy to assume all cleaning services work the same, but Corvus Janitorial Systems proves otherwise once you see how structured their approach is.
They use a Total Quality Management system that helps maintain consistent cleaning standards across different types of facilities, from small offices to large warehouses.
A standout is their proactive site audits, where supervisors check for missed areas before clients even complain. Plus, I appreciate that they prioritize eco-friendly cleaning, which means fewer harsh chemical odors around the office.
However, their admin offices are closed on weekends, which can slow communication if issues arise. Since they rely on local owner-operators, service experience can also vary slightly depending on the account.
Always performed high quality work for our tenants
I have worked with Michael Kerby and his team for years on a mid sized office building and have always found their team to be reasonably priced, responsive, proactive about materials, and always performed high quality work for our tenants. We are happy to recommend them for future work.

Has been a truly positive experience
Working with Corvus Janitorial has been a truly positive experience. What stood out to me the most wasn’t just the cleaning services—they were good—but the people in the office who run everything behind the scenes.

3. CCS Facility Services

Website: https://ccsbts.com/locations/denver/
Address: 1485 S Lipan St.
Contact: +1 303-733-8997
Hours: Monday–Friday: 8:00 AM – 5:00 PM
Looking for more than just standard cleaning? CCS Facility Services goes above and beyond, earning the distinction of being the first global recipient of GBAC STAR™ accreditation.
Their expertise in infection prevention truly sets them apart from basic maintenance companies. Their services go beyond surface cleaning, especially in large buildings where safety and hygiene standards are strict.
They’re a great partner for HVAC professionals, doing the cleaning after a messy service.
I also found it impressive that they offer 24/7 emergency response for situations such as floods or contamination. Plus, they have LEED certification support for eco-conscious buildings.
The downside is that they may feel too large for small offices that just need simple cleaning. Their corporate structure can also make communication feel less personal compared to smaller local providers.
Any concerns are addressed immediately and don’t occur again
CCS Facility is an awesome company and are very reliable! We have been through several cleaning companies in the past 10 years and I will say that I have finally find a good company to clean our facility. If I have any concerns, they are addressed immediately and don’t occur again. Communication with them is amazing.

4. Big League Clean

Website: https://www.bigleagueclean.com/
Address: 1550 Larimer St.
Contact: +1 833-693-1311
Hours: Available 24 hours
If fast response matters more than anything, Big League Clean instantly stands out. They operate 24/7, which is rare in the janitorial industry, making them ideal for offices with unpredictable schedules or emergency cleanup needs.
I like their month-to-month service model because it avoids long-term contracts and offers greater flexibility. They also assign dedicated account managers who check in regularly to ensure service quality stays consistent.
On the downside, their pricing is higher than that of standard cleaning companies, especially for urgent or after-hours jobs. They’re also in high demand, so scheduling can get tight for one-time clients.
Even so, their speed and communication make them a strong choice for busy urban businesses.
Adaptable to possible changes/challenges
I would absolutely recommend Big League Clean! They are true professionals and work diligently to provide top of the line service to their clients. The team is respectful with our work space, adaptable to possible changes/challenges that arise and communicates exceptionally well. Highly recommend!

5. Metro Maintenance, Inc.

Website: https://metromaintenance-inc.com/
Address: 4601 Quebec St.
Contact: +1 720-359-1544
Hours: Monday–Friday: 8:00 AM – 5:00 PM | Saturday: 8:00 AM – 1:00 PM
A cleaning crew that actually remembers your workspace habits is rare. But Metro Maintenance, Inc. is known for exactly that kind of consistency.
They’re locally owned with over 22 years of experience, boasting a team that is IICRC-certified. They’re especially great in carpet cleaning and water restoration, which adds extra value to office maintenance.
I love that they often send the same staff to repeat clients, which helps build familiarity.
I also like that they offer Saturday administrative support, making scheduling easier for busy managers.
However, their service area is mostly limited to Greater Denver, so they may not handle distant locations. They also don’t have the large-scale resources of bigger franchise networks during emergencies.
Professional and their work is absolutely the best
Outstanding service! These guys are professional and their work is absolutely the best. With pets and kids, I didn’t think there was hope for my white carpets, until Metro Maintenance. Before and after photos below.
