Compare scope before price
The lowest total may omit work included elsewhere. Normalize demolition, disposal, permits, preparation, product specifications, cleanup and restoration before comparing. An allowance can move later, so separate it from defined-price work.
Verify contractor information
Check licensing requirements, insurance, references and permit responsibility using authoritative local sources. Confirm who supervises the site and how subcontractors are managed.
Review contract terms
Payment schedule, change-order approval, start conditions, cleanup, dispute terms and warranty responsibilities can matter as much as price. Do not rely on verbal promises that are absent from the written agreement.
FAQ
Does the highest score mean the best contractor?
No. Scores reflect your entries and only organize comparison. They are not verification or a recommendation.
Should allowances be removed?
No. Displaying them separately helps show uncertainty. Final selections can move the contract total.
