A cleaning estimate should be based on the property and requested work, not an invented industry-wide premium or a promise that one product category always costs more.
Main cost drivers
- Square footage, rooms, layout, and current condition
- First-clean detail compared with recurring maintenance
- Frequency, access window, parking, stairs, elevators, and travel
- Add-ons, specialty surfaces, customer-supplied requirements, and equipment
- Crew size, expected duration, documentation, and change requests

Ask each provider to identify included tasks, exclusions, supplies, taxes or fees, and how added work is approved. Product preferences are one planning factor among many. The written estimate should control, and a revised scope should be confirmed before the price changes.
