Why These Questions Matter Before You Sign
Hiring a contractor is one of the most financially significant decisions a homeowner makes. Whether you're remodeling a bathroom, adding a room, or replacing a roof, the person you hire can determine whether the project finishes on time, on budget, and up to code — or becomes a months-long headache. The good news: most problems are preventable when you ask the right questions before any contract is signed.
This checklist is designed to help you interview contractors with confidence. Use it across every bid you collect. See our homeowner's renovation roadmap for context on where contractor hiring fits within the broader project timeline.

Tools and Resources to Have Ready
Before you sit down with a contractor, gather a few key resources so you can verify their answers on the spot and track what each bidder tells you.
State Contractor License Lookup
Verify a contractor's license status, issue date, and any disciplinary history directly through your state licensing board's website.
Bid Comparison Spreadsheet
Track and compare itemized bids from multiple contractors side by side, including labor, materials, timeline, and payment terms.
Certificate of Insurance Request Form
A standard form you can ask the contractor's insurer to complete, confirming coverage details and policy dates.
Reference Interview Notes Template
A simple structured form to record answers when you call contractor references, so you can compare feedback consistently.
Local Building Department Contact
Confirm which permits are required for your specific project type and jurisdiction before work begins.
Once you've collected multiple bids, review them side by side. Significant price differences often reflect differences in materials, labor scope, or what's been left out — not simply contractor greed or generosity. Be cautious of assumptions like "any licensed contractor will do" — the renovation myths that cost homeowners money article breaks down why vetting still matters even for smaller jobs.
What Happens After the Interview
Once you've narrowed your list, the next step is reviewing the actual contract. A signed agreement should spell out payment schedules, material specifications, timeline milestones, change order procedures, and warranty terms. Don't rely on verbal promises — if it isn't in writing, it doesn't exist legally. Our guide to renovation contract terms that protect homeowners walks through the clauses that matter most.
Never Pay the Full Amount Upfront
Legitimate contractors do not typically require full payment before work begins. A common and generally reasonable structure is a modest deposit (often 10–30% depending on project size), with remaining payments tied to completed milestones. If a contractor insists on full or near-full payment before starting, consider that a significant red flag. Always confirm payment terms are spelled out in the written contract before signing.
If payment terms feel unclear or a contractor asks for more than a reasonable deposit upfront, treat that as a signal to ask more questions or seek another bid.
