How do I give an estimate for cleaning a 15.000 sqf church?

Hi, goianig!

This place doesn't work the same way that a chat room does. You had placed your question on the really old thread of someone else that has been archived and thus is not generally visible to everyone who might respond. I've titled and moved your question to a thread on its' own so that it will be recognized and addressed as being your own question.

Thanks!

How much total square feet?

How many days per week?

Do you have windows, VCT (hard floors), and carpet to do?

How much do we charge to clean a 15000ft building final clean

Impossible to answer as asked. We have no idea as to what you will be doing. People, taxes, insurance, bonding, materials, profit??
