Contractor estimate comparison guide
The cheapest estimate is not automatically the same project at a lower price.
Compare work line by line
Check demolition, prep, materials, disposal, permits, cleanup, and final finishes before comparing totals.
Find the allowances
Cabinets, tile, fixtures, and appliances may be placeholders; confirm what happens if your selections cost more.
Read exclusions and assumptions
Look for hidden gaps such as rot repair, utility upgrades, painting, or permit fees.
Compare execution terms
Review schedule, payment milestones, change-order process, warranty, and who is responsible for inspections.
Before you use the checklist
Read this as a scope-control page. The value is in making vague project language visible before it becomes a vague quote. Write down the current condition, the preferred outcome, and the items you are not asking the contractor to include.
If a contractor answers these questions clearly, their estimate is easier to compare even when the total is not the lowest. If an answer is missing, ask for the assumption in writing before treating the price as complete.

How to use this page
Use this page as a planning filter before you ask for bids. The goal is not to guess an exact contractor price; it is to name the project conditions that make two estimates legitimately different.
For contractor estimate comparison guide, start by writing down the visible scope, the house conditions you already know, and the choices you are still willing to change. Then compare those notes against the related calculators and guides linked below.
What to verify before comparing quotes
A useful estimate should state what is included, what is excluded, and what assumptions might change after inspection.
When two prices are far apart, look first for differences in prep, access, disposal, permits, materials, warranty language, and repair allowances. Those details usually explain more than the headline number.
