How It Works
Estimating Cleaning Time and Cost
Cleaning time depends on home size, number of occupants, and how thorough the cleaning needs to be.
Estimation
Weekly Hours = (Sq Ft / 1000) x 1.5 + Occupants x 0.3
A 2,000 sq ft home takes approximately 3-4 hours per cleaning session. More occupants and pets generate more mess, increasing time proportionally.
Worked Example
A 2,000 sq ft home with 3 occupants, professional cleaning at $35/hr.
- 01Base hours = (2000/1000) x 1.5 + 3 x 0.3 = 3.0 + 0.9 = 3.9 hours
- 02Monthly cost (2x) = 3.9 x $35 x 2 = $273
- 03Annual cost = 3.9 x $35 x 24 = $3,276
