Quote-comparison checklist
A low total can reflect a narrower scope. Ask each contractor to answer the same checklist in writing before comparing price.
- Ask for a room-by-room scope with labor, material allowances, permits, design, demolition, cleanup, and warranty terms separated.
- Confirm who coordinates licensed plumbing, electrical, gas, HVAC, and inspection work and who is responsible for corrections.
- Compare the same cabinet, fixture, countertop, tile, appliance, and finish assumptions across bids.
- Ask for diagnosis, labor, parts, permit handling, cleanup, warranty, and excluded restoration as separate line items.
- Confirm whether the price includes travel, dispatch, after-hours premiums, testing, disposal, and return visits.
