Questions to ask a contractor before hiring
The best contractor questions do not perform suspicion; they make the job easier to price, run, and remember accurately.
Ask what exactly is included
What work is included, excluded, assumed, or carried as an allowance? Which materials, prep steps, repairs, disposal, and permits are inside the number?
Ask how the job will run
Who supervises daily work, what schedule is realistic, how are delays communicated, and what needs to be selected before the crew arrives?
Ask how money changes hands
What is the payment schedule, what triggers each milestone, and how are change orders priced and approved before extra work starts?
Ask what happens after completion
What warranty is provided, what documentation will be handed over, who closes permits, and how are punch-list items handled?
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.

That internal path matters: the checklist clarifies scope, the guide explains cost drivers, and the calculator gives a first planning range.
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 questions to ask a contractor before hiring, 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.
FAQ
Should I ask every contractor the same questions?
Yes. A consistent question set makes estimates easier to compare and reveals where one proposal is less complete than another.
Is the lowest bid a red flag?
Not automatically. It becomes risky when the lower number comes from missing scope, vague allowances, or unclear execution terms.
