If you’ve ever called around for a cleaning quote, you probably heard a lot of “cents per square foot.” While that sounds simple, it’s often a trap. If a company prices your building based only on its size, they’re guessing at your workload—and when they guess wrong, it’s your office cleanliness that suffers.
At Optimal Prime Cleaning Services, we don’t just look at the floor; we look at the flow. Here is how we build a fair, transparent price for your Sioux Falls facility.

The Walkthrough: Our Fact-Finding Mission
We don’t give “ballpark” quotes over the phone because your building is unique. During our walkthrough, we focus on three main areas:
- The Usage Map: A 5,000 sq. ft. warehouse and a 5,000 sq. ft. medical clinic require vastly different levels of care. We look at how your space is used and which areas see the most action.
- The Restroom Audit: We count fixtures (sinks, stalls, urinals) and assess their current condition. Restrooms are the most labor-intensive part of any job, so getting this right is key to a healthy building.
- Floor Type Inventory: We note where you have carpet, LVP, tile, or sealed concrete. Each requires different equipment and different amounts of time to clean properly.
Why Square Footage is Only the Starting Line
Relying solely on square footage leads to “rushed service.” If a cleaner is given a price that only accounts for size, they are forced to cut corners to stay profitable.
We go deeper by analyzing the Density of the Workload. * An office with 50 cubicles takes longer to dust and vacuum than an empty carpeted hall of the same size.
- We factor in the “touch-point” count—the number of door handles, light switches, and elevator buttons that need daily disinfection.
The “Optimal Prime” Method: Data + Experience
We combine our local Sioux Falls experience with industry-leading data to make sure our timing is accurate.
- Workload Analysis: We use internal software that breaks your building down into tasks and assigns a time value to each.
- ISSA Benchmarking: We compare our estimates against the International Sanitary Supply Association (ISSA) standards. This ensures our labor rates are backed by global industry data.
- The “Feel” Factor: Data is great, but human intuition is better. Our experienced team reviews every automated estimate. If we know that “South Dakota winter” salt-tracking will add ten minutes to your entryway care, we build that in.
Our Pricing Philosophy: Transparency Over Everything
We don’t want to be the cheapest company in town; we want to be the most reliable. Our goal is to provide a price that allows our team to:
- Spend the time necessary to actually disinfect, not just wipe.
- Use high-quality, hospital-grade chemicals.
- Pay our staff a fair wage so you see the same friendly faces every week.
When you receive a proposal from us, you aren’t just getting a number. You’re getting a documented plan that shows exactly where your investment is going.
