Confirm every bid is pricing the same scope#
Before comparing dollar figures, compare what's actually included. Two contractors can walk the same space and return numbers $5,000 apart because one itemized tear-out and disposal while the other assumed an overlay.
- Removal and disposal of old materials — included or billed as an extra?
- Exact material specifications — "tile" is not a spec; "12x24 glazed porcelain with epoxy grout" is.
- Scope omissions — verify stair railings, gates, or underlayment were not silently dropped.

Payment schedules reveal contractor stability#
How a bid asks to be paid tells you almost as much as the number itself. Standard deposits should be 10–20%, with subsequent payments tied to completed milestones.
