If you manage an office in Sioux Falls, Brandon, or Harrisburg, you’ve likely wondered if your cleaning crew is spending enough time on your space—or perhaps too much. While square footage is the starting point, it isn’t the whole story.
At Optimal Prime Cleaning Services, we know that a high-traffic clinic off 41st Street has very different needs than a quiet professional suite in the Shriver Square building. Here is a breakdown of what determines cleaning speed and what you should expect.
The Baseline: 45 to 90 Minutes
For a standard 1,000 sq. ft. office, a professional cleaner usually needs between 45 and 90 minutes per visit. This timeframe covers a “maintenance clean,” which keeps the office tidy and sanitary on a day-to-day basis.
What happens during those minutes?
- Emptying trash and recycling.
- Wiping down desks and shared tables.
- Cleaning and disinfecting the restrooms.
- Cleaning the breakroom or kitchenette.
- Vacuuming carpets and mopping hard floors.
Why Some Offices Take Longer
Size is a constant, but “density” changes. Here are the four main reasons one office takes 45 minutes while another takes double that time:
- The “Room” Factor: An open-concept office with rows of desks is fast to clean. An office divided into six small rooms with doors, handles, and baseboards takes much longer because of the extra detail work.
- Restrooms and Breakrooms: These are the most labor-intensive areas. If your 1,000 sq. ft. space has two restrooms instead of one, or a kitchen with a coffee station that sees heavy use, the clock stays running.
- Floor Materials: It generally takes more time to properly vacuum a high-pile carpet than it does to run a microfiber mop over a sealed concrete floor.
- Foot Traffic: If you have clients walking in and out all day, dirt builds up faster. A high-traffic office requires more “spot cleaning” on glass and more intensive floor care.
Does Frequency Save Time?
Yes. There is a direct link between how often we show up and how long we stay.
- Daily Cleaning: The “soiling” never gets out of hand. Each visit is shorter and more efficient.
- Weekly/Bi-Weekly: Dust settles and grime builds up in sinks. The cleaner has to work harder to get the space back to a baseline, which means longer individual visits.
- Periodic Deep Cleaning: This is a separate service entirely—like our low-moisture carpet cleaning or hard floor restorative care. These are the deep dives that keep your facility looking new.

When to Rethink Your Cleaning Schedule
Your cleaning needs aren’t static. You should re-evaluate your plan if:
- You’ve hired more staff and the office is “tighter.”
- You’ve moved furniture or added new partitions.
- It’s flu and cold season (disinfection needs to be more thorough).
- You’ve extended your business hours.
