A finish-floor estimate is incomplete until the substrate has been inspected against the selected product requirements.
Inspect before demolition assumptions become prices
Look for movement, squeaks, staining, soft areas, cracks, high spots, low spots, adhesive residue, and transitions to adjacent rooms. Some conditions remain hidden until old flooring is removed, so define how discoveries will be documented and priced.
Moisture testing methods and acceptable results depend on the substrate, adhesive, and flooring system. Follow current manufacturer requirements rather than a generic internet threshold.
Define preparation as line items
Separate removal, disposal, scraping, grinding, patching, leveling, panel replacement, fastener work, moisture control, and cleaning. State whether door trimming, baseboards, toilets, appliances, and transitions are included.
Avoid open-ended allowances
Use an inspection-based allowance with unit prices where possible. Require approval before exceeding it, and document the affected area. This protects both owner and contractor from vague scope disputes.
