hi there
for floor work, you should measure the floor areas for the differing coverings ie.
2000 sq ft carpet,
2000sg ft laminate
2000 sq ft hard concrete floor
then you can apply your costs for vacuuming, sweeping and mopping as required to the different areas,
for instance a laminate area may need sweeping daily, and then twice a week is mopped, so you would then apply the two different cost operations to that floor area,
as long as you have it all written down, and filed away then you can refer back to it in the future, also very useful, when the client has any refurbishmnet or extension work done, so that you can adjsut your pricing and schedules accordingly.
