Why the Interview Stage Matters
Hiring a contractor is one of the more consequential decisions a homeowner makes. A good match means a project finished on time, on budget, and to code. A poor one can mean unfinished work, hidden defects, or legal headaches that take months to untangle. Most problems stem from skipping due diligence at the start — when it's still easy to walk away.
This checklist covers every category of question worth asking before you sign anything. Use it during phone calls, in-person estimates, or when comparing bids. If a contractor is reluctant to answer these questions clearly and in writing, that reaction itself is useful information.
For projects that involve structural changes, be sure to read what every homeowner should know about load-bearing walls before your consultation, so you can speak knowledgeably about scope. And if you're unsure whether your project needs a permit, review when permits are required and what happens if you skip one — it directly affects what questions you need to put to your contractor.
State Licensing Board Website
Verify the contractor's license status, expiration date, and any complaints or disciplinary actions on record.
Certificate of Insurance Form
Request this document directly from the contractor's insurer — not the contractor — to confirm active general liability and workers' comp coverage.
Written Bid / Scope of Work Template
A structured document that captures project scope, materials, exclusions, timeline, and cost — essential before signing any contract.
Reference Call Notes Sheet
A simple form for recording answers from contractor references so you can compare responses across multiple candidates.
Local Building Department Contact
Confirm which permits your specific project requires and verify that the contractor has pulled them once work begins.
The Checklist
Work through these questions in roughly this order: licensing and credentials first, then project specifics, then the contract and payment terms. Document every answer — either in writing from the contractor or in your own notes taken during the conversation.

Never Skip the Written Contract
A verbal agreement gives you very little protection if a dispute arises. Every project — regardless of size — should have a signed written contract that specifies scope, materials, cost, payment schedule, timeline, and warranty terms. If a contractor refuses to put the terms in writing, that is a serious red flag. Review the contract carefully before signing and keep a copy for the duration of the project and beyond.
Watch Out for 'Cash Only' Requests
Contractors who insist on cash-only payment or who quote prices dramatically lower than competitors may be unlicensed, uninsured, or cutting corners on materials and labor. Paying by check or a traceable method creates a paper trail that protects you. If something feels off during the bidding process, trust that instinct and get additional quotes.
Once you've hired a contractor, staying organized through the project matters just as much as the vetting stage. The household management hub has practical tools for tracking home projects and maintenance schedules. You may also find it helpful to run a monthly home walkthrough before your contractor begins, so you can document existing conditions clearly.
