How the math works

Office janitorial $0.10-0.30/SF/month for daily clean. Add quarterly carpet cleaning ($0.05-0.10/SF), 2x annual window washing, and consumables (toilet paper, soap, trash bags). Special-use buildings (medical, lab, restaurant) cost 2-4x more.

Hybrid work (3-day office) lets buildings shift to MWF cleaning, often cutting cost 30%.

Frequently Asked Questions

Day porter add-on?

Day porters (8 hr lobby/restroom maintenance during business hours) add $40-80K/yr per FTE. Common in Class A office and high-traffic retail.

Hybrid work cost reduction?

Switching from 5-day to 3-day cleaning typically saves 30-40%. Many buildings transitioned post-COVID. Some kept daily restroom service even with reduced floor cleaning.

Specialty buildings?

Medical office 2-3x standard ($0.30-0.60/SF/mo); biotech and lab 3-4x ($0.50-1.20); restaurants 4-5x. Reflects regulatory cleaning requirements and biological contamination risk.
