Every contractor horror story I've ever heard — and after 23 years in this industry, I've heard hundreds — starts the same way: the homeowner liked the contractor. They seemed professional. They came recommended. The estimate was fair. The whole thing felt right.
The problem wasn't that these homeowners were naive. The problem was that they were evaluating the contractor on the wrong signals. Likability, referrals, and gut feelings are not due diligence. The questions you ask before signing anything — and what you do with the answers — are the only reliable filter you have.
What follows are the 12 questions I would ask before trusting anyone with a project. Not the questions you see on generic checklists. The ones that actually reveal how a contractor operates, where their financial pressure points are, and whether they'll be standing behind their work three months from now.
The 12 questions
- Are you licensed in this state, and can I verify it directly?
- Can your insurer send me a certificate of insurance directly?
- How long have you been doing this specific type of work?
- Can you give me three references from similar projects in the last 12 months?
- Who exactly will be doing the work on my project?
- How many active projects are you running right now?
- What does your payment schedule look like?
- Can I see a draft contract before we agree to anything?
- How do you handle change orders?
- What is your projected start and completion date?
- What permits does this project require, and who pulls them?
- What warranty do you offer on your work?
Are you licensed in this state, and can I verify it directly?
Licensing requirements vary by state, but in most jurisdictions, any contractor doing work above a certain dollar threshold must be licensed. The license number should be on their business cards, website, and contract. Don't just ask — look it up yourself through your state's contractor licensing board. It takes three minutes and tells you far more than their answer.
What you're checking: Is the license current? Is it in the contractor's name or their company name? Has it ever been suspended or revoked? Have any complaints been filed? This is public information.
"I've been doing this for 20 years" — That's not a license number. Any contractor who responds to a licensing question with a years-in-business answer is either unlicensed or hoping you won't push on it.
Can your insurer send me a certificate of insurance directly?
Every legitimate contractor carries general liability insurance and workers' compensation. General liability protects your property if something gets damaged during the project. Workers' comp protects you from being liable if a worker gets injured on your property — and without it, that liability can come back to you and your homeowner's insurance.
Ask for the certificate to come directly from their insurer (or their insurer's certificate portal) — not a PDF they email you. A certificate of insurance is easy to forge and easy to let lapse. You want current documentation from the source.
"I'm covered, don't worry about it" or "I'll send you a copy later." Later never comes, and verbal assurances are worthless if someone breaks an ankle on your property.
How long have you been doing this specific type of work?
A contractor who has been in business for 15 years but spent most of that time on commercial jobs is a different risk profile for your kitchen remodel than one who has done 200 residential kitchens. Years in business is less useful than years doing work that matches your project type and scale.
The follow-up is: can you show me photos and a reference from a project similar to mine in terms of scope and budget? Not their best project — a comparable one.
"We do everything — kitchens, bathrooms, additions, roofing." A contractor who does everything at high quality is rare. Specialists exist for a reason. Generalist positioning isn't disqualifying on its own, but it warrants harder questions about your specific project type.
Can you give me three references from similar projects completed in the last 12 months?
References matter — but how you use them matters more. Most homeowners receive a reference list, call one person, and hear that everything was great. That's almost useless. The references a contractor provides are hand-selected. The ones they don't provide are the ones who would tell you a different story.
When you call references, ask these specific questions: Did they finish on time? Did the final cost match the estimate? Were there unexpected charges, and how were they handled? Would you hire them again for a project of similar scope? If the reference pauses on any of those questions, pay attention to the pause.
"Our references are on Google — you can check our reviews there." Online reviews are easy to curate. You want to have an actual conversation with someone who wrote a check and watched the work get done.
Who exactly will be doing the work on my project?
The contractor who shows up for the estimate is not always the person who shows up on day one with tools. Many contractors function primarily as project managers and salespeople — the actual work is done by crews they hire on a project-by-project basis or by subcontractors across multiple trades.
This isn't automatically a problem. Subcontracting is standard practice in construction. What matters is: are the people doing the work licensed in their trade? Is the general contractor carrying workers' comp that covers them? And who is responsible if a subcontractor does work that doesn't meet code?
"My guys" — with no elaboration on who "my guys" are, whether they're employees or subs, and whether they're covered under the contractor's insurance policy. Unlicensed, uninsured subcontractors are one of the most common ways homeowners end up with liability exposure they didn't expect.
How many active projects are you running right now?
This is the question most homeowners never think to ask, and it's one of the most important ones. A contractor managing 8 active jobs simultaneously with a crew of four is mathematically incapable of giving any one of those projects consistent attention. Your project will get slotted into the rotation — and when scheduling pressure hits, whoever applies the least pressure falls to the back.
There's no universal "right" number. A large company with multiple project managers can handle more volume than a small owner-operated crew. What you're assessing is the ratio: how many projects, how many people, and is there any slack in that system to absorb the unexpected?
"We're very busy right now — I'll have to squeeze you in." "Squeezed in" means you're already the low-priority job before work has started. A contractor who's overextended on the front end will be overextended every day of your project.
A homeowner in the Tri-State area signed with a contractor who had four other active jobs at the time of estimate. Work started on schedule, then slowed to two or three days a week. Then one week with no crew at all. The contractor was rotating his team across all five sites based on which homeowners were the most vocal. The homeowner's bathroom remodel that was scoped for six weeks took four months. At no point was the contractor dishonest about his workload — the homeowner never asked.
What does your payment schedule look like?
This question has one right answer: milestone-based payments. Upfront deposit to mobilize (10–15% max), then percentage draws tied to completed, verifiable phases of work. Any other structure — large upfront payments, calendar-based draws, or "pay as we go" — is a structure that benefits the contractor, not you.
If a contractor asks for more than 15–20% upfront, ask them to walk you through why. A specific answer about material deposits is acceptable. A vague answer about "covering costs" is not. The deposit conversation tells you almost everything you need to know about how they manage their cash flow.
"We need 40% down to start, then we'll bill as work progresses." A 40% deposit before work begins means you've funded most of your leverage before a single tool comes out of the truck. This is not how financially stable contractors operate.
Can I see a draft contract before we agree to anything?
This request separates contractors who have a standard, professional contract from those who write one up at signing. A reputable contractor can provide their standard agreement before you've committed. If they resist — "we do the contract once you're ready to move forward" — that's a warning sign. The contract is a document you need time to review without the social pressure of a closing conversation.
Read it before you're emotionally committed to the project and to the contractor. The things you're looking for: detailed scope of work, milestone payment schedule, specific completion date, written change order requirement, lien waiver language, and warranty terms. If any of those are absent, you now know what to negotiate before signing.
"We'll go over the contract when we meet to sign." This means you're expected to review and sign in the same sitting, with the contractor present. That is not a review. That is signing under social pressure.
How do you handle change orders?
Every project has surprises. The question isn't whether change orders will happen — it's what the process looks like when they do. A contractor who says "we document everything in writing before any additional work starts" is describing a professional process. A contractor who says "we handle it as we go" is describing a process that ends in disputes.
The specific language you want in the contract: no additional work commences and no additional costs are incurred without a written change order signed by both parties. Verbal authorizations are not valid. If a contractor tells you this slows things down too much, that's the point.
"We'll figure it out as we go — I've never had a problem with that." Every homeowner who has been surprised by a 30% budget overrun heard this exact sentence before work started.
What is your projected start and completion date?
Get a specific start date and a specific completion date in writing — not a range, not an estimate. If the project needs to run longer due to circumstances outside their control, there should be a defined process for that. There should also be a daily penalty clause for delays that are within their control: a dollar amount per day past the completion date.
Most contractors push back on delay penalty clauses. That pushback is worth examining. A contractor who is confident in their scheduling and execution shouldn't object to a $150/day delay penalty on a $50,000 project. One who does is telling you something about their expectations.
"We're thinking 6–8 weeks, depending on materials and weather." Vague timelines are not timelines — they're a preemptive excuse. Every legitimate project can produce a target completion date with documented exception conditions.
What permits does this project require, and who pulls them?
Permits aren't bureaucratic friction — they're inspections that verify work is done to code. A contractor who discourages permits or suggests you pull them yourself is waving a significant red flag. When the contractor pulls the permit, they're legally responsible for the work passing inspection. When you pull it, that responsibility transfers to you.
Unpermitted work creates problems when you sell the home, refinance, or when something fails that wasn't inspected. The cost of permitting is real but it's small relative to the cost of remediation later.
"We can skip the permit — it'll save you money and avoid the hassle." This is the contractor protecting themselves from inspection, not saving you money. Work that fails inspection is work they'd have to redo.
What warranty do you offer on your work?
Most quality contractors offer one to two years of labor warranty on their work — meaning if something they installed or constructed fails due to workmanship issues within that period, they come back and fix it at no charge. Materials typically carry manufacturer warranties separate from the contractor's labor warranty.
Get the warranty terms in the contract. "We stand behind our work" is a sentiment, not a warranty. You want: coverage period, what it covers (labor vs. materials), and the process for making a warranty claim.
"We've never had a callback — our work speaks for itself." No warranty language means no enforceable obligation to return. Every tradesperson has callbacks. A contractor who claims otherwise either isn't doing enough volume to have seen problems yet, or isn't answering when problems arise.
What to Do With the Answers
These twelve questions are not meant to be fired at a contractor like an interrogation. They're meant to shape a conversation — one that helps you understand how a contractor thinks, how they operate, and where their pressure points are.
Most contractors will answer most of these questions reasonably. What you're watching for is the pattern: Do they get defensive when you ask for documentation? Do they pivot from specific questions to vague reassurances? Do they rush any part of the pre-contract process? Defensiveness around documentation is the single most reliable pre-hire warning sign I've seen across 23 years of working in and around this industry.
A contractor who welcomes these questions — who has a license number ready, who offers to send an insurance certificate directly from their agent, who pulls out their standard contract draft without being asked — is a contractor who has run professional projects before. That's not a guarantee. But it's the right starting point.
The rule: Ask every question before you're emotionally committed. Once you've told a contractor you want to move forward, your leverage in every subsequent conversation drops. The time to establish documentation standards, payment structures, and warranty terms is before any agreement — not after you've shaken hands on a price.
If you're hiring a contractor soon, the next step is reading about what happens after this conversation — specifically, what the contract needs to say and how to maintain financial control through the project. Those topics are covered in the other two articles in this series:
5 Warning Signs Before Hiring a Contractor covers the behavioral red flags that show up during and after this conversation — pressure tactics, vague scope, refusal to document.
How to Avoid Getting Screwed by a Contractor covers what happens once work starts — the deposit trap, change order bleed, ghost jobs, and the final payment hostage situation.
