Log crew visits, equipment on site, and moisture readings every day. When the invoice arrives — you have the documentation to dispute every inflated line item.
Per IICRC S500, equipment must stop when ALL locations reach ≤16% WME. The date that happens is when billing should stop. Ask the tech for the WME reading at each location on every visit.
Demolition Record
Log only if demo happened today
Why this matters
Demo scope on your invoice must match what was actually removed. Record SF of drywall, LF of baseboard, SF of flooring — before it is gone.
