What ISSA says moves the rate
- Building type and use. High-traffic and high-touch spaces cost more.
- Frequency. ISSA says more frequent cleaning often lowers the per-square-foot rate.
- Soil level and the condition of the space.
- Which services are in the scope. ISSA names trash removal, restroom sanitation, carpet cleaning, hard floor care, disinfection, and window cleaning as items that change the rate.
- Labor costs, including wages, benefits, and staffing.
- Equipment, chemicals, and technology.
How ISSA says to read a bid
- Ask for a written scope with tasks and frequencies.
- Compare more than one proposal, not just the total.
- Use cleanable square feet, which is what ISSA divides into the monthly contract cost.
- Walk the building before treating any range as the price.
- Treat the lowest number as a comparison point, not as Strong Tower’s rate.
