Questions to Ask a Contractor Before You Hire (and What a Good Answer Sounds Like)
Most lists of questions to ask a contractor before hiring stop at giving you the question. That is half the job. The useful part is knowing what a good answer sounds like versus a bad one, because a contractor who has done this a hundred times has a smooth answer ready for almost anything — the tell is usually in the specifics, not the confidence.
Here is what to ask, and what separates a real answer from a rehearsed one.
Are you licensed, bonded and insured for this specific work?
Good answer: They tell you which jurisdiction licensed them, they offer to send a certificate of insurance directly from their insurer or agent (not a forwarded PDF), and they don’t seem bothered by the question.
Bad answer: “Don’t worry about it,” a vague “yeah we’re covered,” or a certificate that only they can produce and that arrives from their own email with no way to confirm it with the insurer. We cover this one in full detail, including why licensing in the St. Louis area is handled locally rather than through one statewide license, in what licensed, bonded and insured actually means.
Who is actually going to be in my house — employees or subcontractors?
Good answer: A straight answer either way. Plenty of good contractors use subcontractors for specialty work, and that’s fine — the point is they tell you, and they confirm the subs carry their own insurance too.
Bad answer: Dodging the question, or you find out on the day of the job that the crew is not who you talked to on the phone and nobody mentioned it.
Can I get the scope of work in writing, including what’s excluded?
Good answer: A written scope that says what’s included, and just as important, what’s not. “Debris removal is not included” or “this quote assumes standard access, add a stated surcharge if the driveway won’t hold the truck” is the kind of specificity that means they’ve actually thought through your job.
Bad answer: A verbal quote with no follow-up document, or a one-line estimate with no detail. Vague scope is where “that wasn’t included” surprises come from later.
What’s the payment schedule, and how much do you want up front?
Good answer: A reasonable deposit tied to materials or scheduling, with the bulk of payment due on completion or in installments tied to milestones you can see.
Bad answer: Full payment up front, or a deposit that feels large relative to the job size, especially from someone you just met. Be wary of paying in full before any work has started — a contractor who needs your entire payment before showing up is asking you to fund the risk that they never do.
What happens if we need to change the scope mid-job?
Good answer: A described change-order process — they’ll tell you the additional cost and get your sign-off before doing extra work, in writing or at least in a text you can point back to.
Bad answer: “We’ll just figure it out” or, worse, a bill at the end with charges you never agreed to.
What’s the timeline, and what happens if it slips?
Good answer: A realistic window, not an unrealistically short one designed to win the bid, plus an honest answer about what causes delays on jobs like yours (weather, permit timing, material availability) and how they communicate if the date moves.
Bad answer: An unusually fast timeline with no explanation of how they’ll do it faster than everyone else, or no answer at all for what happens if things run long.
Who handles cleanup and debris disposal, and where does it go?
Good answer: A specific answer about what leaves the property, who hauls it, and generally where it’s routed. For hauling and cleanout work specifically, a good provider can tell you the difference between donation, recycling, and landfill for what they remove.
Bad answer: “We’ll take care of it” with no follow-up detail. That answer might be true, but it isn’t verifiable, and it’s the answer families most often regret accepting without asking a second question.
Is there a warranty on the work, and what does it actually cover?
Good answer: A specific written warranty period and what it covers — workmanship defects, not damage from unrelated causes — and a clear way to reach them if something needs to be fixed after the fact.
Bad answer: “We stand behind our work” with nothing written down. That’s a sentiment, not a warranty.
Can I talk to a recent customer with a job like mine?
Good answer: References from jobs similar in size or type to yours, offered without much friction.
Bad answer: Reluctance, references that are all old, or references that are conveniently unreachable when you try to follow up.
Who pulls the permits, if this job needs them?
Good answer: A clear statement of whether your job requires permits at all, and if it does, confirmation that they handle the permitting themselves rather than asking you to.
Bad answer: “We don’t usually bother with permits” — which can leave you, the homeowner, responsible for unpermitted work on your own property.
What happens if something breaks or gets damaged during the job?
Good answer: They point back to their liability insurance and describe how a damage claim actually gets handled — who to call, roughly how long it takes.
Bad answer: “That basically never happens.” Confidence is not a claims process.
Red flags that should end the conversation
A few answers are bad enough on their own that they’re worth walking away over, regardless of how the rest of the conversation went:
- Pressure to sign today, especially with a “special price” that expires if you don’t commit on the spot.
- Cash-only, with no invoice or paper trail.
- No written scope of work, only a verbal description of what will happen.
- A bid far under every other quote you’ve gotten, with no explanation for the gap. The gap has to come from somewhere, and it’s rarely good news.
- Refusing to put a certificate of insurance directly in your hands, or only offering one that isn’t verifiable with the insurer.
Any one of these alone is worth a follow-up question. More than one together is usually a reason to move on to the next provider.
Why a directory answers most of this before you ask
Every one of these questions takes time, and asking them cold, over the phone, to a company you’ve never worked with, is not most people’s idea of a good afternoon. That’s the gap STL Home Service Hub is built to close — licensing, bonding, and insurance are verified before a provider is ever in the directory, so a homeowner’s request gets matched to someone who has already cleared that bar, instead of starting the vetting process from zero with every call.
