How do you hire a reliable contractor? A practical checklist
Last updated: July 7, 2026
A reliable contractor can show you a valid license, current liability insurance, real references and an itemized written quote — and accepts protected payment instead of cash up front. This checklist turns that sentence into concrete steps you can run through before hiring any contractor, tradesperson or handyman, whether you found them on a marketplace app or through a neighbor.
What should you check before hiring a contractor?
Run through these ten checks before you commit. None of them takes long, and together they filter out most bad outcomes.
- Verify the license for the trade. Confirm the license exists, is current, and covers the specific work you need — electrical, plumbing and gas licenses are trade- and scope-specific. When in doubt, check with the issuing authority, not the contractor.
- Ask for proof of liability insurance. A serious contractor carries general liability insurance and can show a current certificate. Without it, damage to your property becomes your problem.
- Look for a review history, not a review score. Read the worst recent reviews and how the contractor responded. A long, consistent history beats a perfect score with five entries.
- Ask for references or photos of similar work. Recent, local, and for the same kind of job as yours.
- Get an itemized written quote. Labor, materials, timeline and what is explicitly excluded. Verbal estimates are not quotes.
- Agree how changes will be handled. Scope changes should be written change orders with a price, agreed before the extra work happens — not surprises on the final invoice.
- Never pay large sums in cash up front. A deposit for materials can be legitimate on big jobs; full prepayment in cash is how most hiring horror stories start.
- Prefer protected or escrow-style payments. Money held by a neutral platform until the job is confirmed done protects both of you. See how protected payments work.
- Ask who will actually do the work. Subcontractors or helpers? Are they vetted and insured under the contractor's policy? The contractor answers for everyone they bring.
- Confirm warranty and dispute terms in writing. What happens if something fails a month later, and who decides?
What are the red flags when hiring a handyman or contractor?
Walk away when you see these signs — each one predicts trouble regardless of price.
- Demands full payment in cash before starting.
- No written quote, or a quote dramatically below every other bid.
- Pressure to decide today ("this price is only for now").
- No verifiable identity, address, license or insurance.
- Asks to take a marketplace job off-platform to "save fees" — this voids your payment protection and dispute rights.
- Won't put changes or warranties in writing.
How does a marketplace app help with this checklist?
A good home services marketplace runs several of these checks for you — license verification, insurance documents, background checks — and keeps quotes, changes and payments on the record. That converts the checklist from an hour of homework into a review of what the platform already verified. It does not replace your judgment: vetting is point-in-time, and a badge is not a guarantee, so the written-quote and change-order discipline above still applies.
Qvan, a home services marketplace app currently in pre-launch, is designed to build these checks in: contractors submit trade licenses, liability insurance and tax documents and pass a third-party background check before activation, helpers are background-checked too, and payments are escrow-style. Until launch, apply this checklist to whichever platform or professional you use today.
