What it is
Choosing the right contractor is often the difference between a project that adds value and one that becomes a costly headache. Vetting a contractor means confirming they're licensed, insured, and reputable before you sign — and structuring the deal so you're protected if things go wrong. This is standard consumer-protection guidance that applies to almost any home project.
The checklist
Before you hire
- Get multiple written bids — at least three. Comparing bids reveals the fair market price and exposes outliers that are suspiciously high or low.
- Verify the license. Confirm the contractor holds the license your state or locality requires for the work, and that it's current.
- Confirm insurance. Ask for proof of liability insurance and workers' compensation. Without it, you can be exposed if someone is injured or property is damaged.
- Check references and past work. Ask for recent clients and, where possible, see completed jobs. Look up reviews and any complaint history.
- Confirm they'll pull permits where required — and that permits are in the contractor's name, not yours.
The contract
- Get everything in writing: full scope, materials, timeline, total price, and payment schedule.
- Define change orders (written changes to the agreed scope or price). Any change to scope or price should be written and signed before work proceeds — this is your main defense against scope creep.
- Include a lien waiver (a signed document preventing unpaid subcontractors from making a claim against your home) so you're protected against claims from unpaid subcontractors or suppliers.
Red flags to avoid
- Large upfront payments. Be wary of anyone demanding a big share of the total before work begins. Tie payments to milestones, with a meaningful amount held until the job is complete and inspected.
- Cash-only or "no permit needed" pitches. Both often signal an unlicensed or uninsured operator.
- Pressure to decide now or "today-only" pricing.
- No written contract or vague, verbal-only terms.
- No verifiable license, insurance, or references.
How to think about it
- Cheapest isn't safest. A lowball bid can mean cut corners, missing insurance, or a change-order ambush later.
- Structure payments to keep leverage. Milestone-based payments keep the contractor motivated to finish well.
- Keep records. Save bids, the contract, permits, receipts, and lien waivers — they matter for warranty claims, disputes, and resale. Trusted vendors you've vetted can be saved to your vendor list for next time.
Bottom line
Get at least three written bids, verify license and insurance, check references, put everything in a detailed contract, and never make large upfront payments. Structuring the deal carefully up front is the best protection against a project going wrong.
