How to Compare Contractor Estimates
The lowest number is not necessarily the lowest total cost. Compare what each proposal actually promises to deliver.

Normalize the scope first
Ask each provider to identify demolition, disposal, preparation, materials, quantities, finishes, cleanup, restoration, permits, and excluded work. A short estimate can conceal assumptions that later become change orders.
Compare the commercial terms
- Estimated start and completion timing
- Deposit and progress-payment schedule
- Allowance amounts and who bears overruns
- Change-order approval process
- Labor and manufacturer warranties
- Cleanup, punch-list, and final-payment conditions
Investigate large differences
Ask why one estimate is materially higher or lower. The difference may reflect scope, crew, equipment, access, insurance, material quality, or a misunderstanding—not simply profit.
The Federal Trade Commission recommends getting multiple written estimates and reviewing the work, materials, completion date, and price rather than automatically selecting the lowest bidder.
