15 Questions to Ask a Contractor Before You Sign (2026 Guide)

Most homeowners walk into a contractor site visit with a vague sense that they should "ask some questions" and walk out an hour later having mostly listened. Then a bid arrives in their inbox, the number is the only thing they can compare, and they sign with the cheapest one because they don't have a framework for evaluating anything else.

That's how renovations go sideways. The contractor you hire is making decisions for the next three to twelve months that will affect how you live in your home for the next twenty years. The site visit is the only structured moment in that whole process where you have leverage — they want the work, they're sitting in your kitchen, and they're answering questions in a context they can't easily walk back later. Use it.

The fifteen questions below are the ones that actually surface useful information. They're organized into five blocks — credentials, scope and execution, timeline, money, and communication — so you can run them in order without losing your place. For each one we've included what a competent contractor's answer sounds like, what a worrying answer sounds like, and what to put in the contract regardless of how good the verbal answer was.

Verbal answers are not promises. A competent contractor will let you put any of them in writing without complaint. One who hedges on getting it written down is telling you something.

The 30-second version

If you only have a minute before the site visit:

1. License number, insurance, workers' comp — get all three before any other conversation
2. Detailed written scope — every material, brand, and exclusion in writing, not verbal
3. Payment schedule — never more than 10–30% upfront, milestones tied to completed work
4. Change-order process — written approvals before any extra work begins
5. Three references from the last 12 months — and actually call them

Now the longer version, with the rest of the questions and what to listen for in the answers.

Block 1 — Credentials and Track Record

These three questions gate everything else. If a contractor can't answer them in under sixty seconds with documents to back them up, the site visit is over.

1. Are you licensed in this state, and what's your license number?

A licensed contractor knows their license number the way you know your phone number. It should come out without hesitation, ideally already printed on a business card or proposal cover sheet.

What you do with the number matters more than getting it. The point is not to take their word — it's to verify the license independently with your state's licensing board before you sign anything. Status, expiration, classification, and disciplinary history all live in the state record. We've written a full walkthrough of what to check and how in our contractor license verification guide.

Red flags: "I'm working under another contractor's license," "It's pending renewal," "We're a registered business so we don't need one." A few states use registration instead of licensing — but you should know which one applies in your state before the contractor tells you.

Get in writing: the license number on the contract itself, with the legal business name that matches the state record.

2. Do you carry general liability and workers' compensation insurance? Can you have your insurer send me a certificate directly?

There are three pieces here, and they protect you against three different things: liability covers damage to your property, workers' comp covers injuries to the crew, and bonding (where required) covers abandonment.

The phrase that matters is "send me a certificate directly." A certificate the contractor hands you can be expired, fabricated, or for a policy that was canceled last month. A certificate emailed straight from the insurer's broker is current as of that day. Reputable contractors do this routinely — it takes their broker thirty seconds.

Red flags: reluctance to involve the insurance company, certificates older than a few weeks, a workers' comp policy that "covers them personally" but not their crew (this almost always means the crew is uninsured).

Get in writing: policy numbers, carrier names, dollar limits, and a contract clause requiring the contractor to maintain coverage through project completion.

3. How long have you been in business under this company name, and have there been previous business names?

The question is not "how long have you been a contractor." Plenty of good contractors have been swinging hammers for decades. The question is how long this specific business entity has existed.

Frequent rebrands are the most common pattern in contractor fraud. A contractor accumulates complaints under one LLC, dissolves it, and re-registers under a slightly different name. The state license database often catches this — the same person shows up with multiple license numbers across years — but only if you look. Asking the question directly forces them to either tell you about prior names or risk being caught in an omission later.

A long-running entity isn't a guarantee of quality, but it's a strong signal that the contractor has at least successfully kept clients happy enough to avoid being sued out of business.

Red flags: a brand-new business that claims "twenty years of experience," vague answers about prior entity names, an address that's a mailbox or coworking space.

Get in writing: the legal entity name, EIN if available, and a representation in the contract that the contractor has not had a license revoked or suspended in any jurisdiction.

Block 2 — Scope and Execution

This is the block most homeowners skip. The credential block feels like due diligence; this one feels like nitpicking. It is not nitpicking. Scope ambiguity is the single largest source of cost overruns and disputes in residential renovation, and the way you prevent it is by asking these questions on day one.

4. Will this be a fixed-price bid or time-and-materials? What exactly is included, and what's specifically excluded?

These are two questions wedged into one because they almost always have to be answered together.

A fixed-price bid gives you a single number for a defined scope. The contractor takes the risk if the work runs long; you take the risk if you change your mind about the scope. Most residential remodels should be fixed-price.

Time-and-materials charges you for actual labor hours plus a markup on materials. The contractor's risk is lower; yours is higher. Appropriate when the scope is genuinely unknowable — emergency water damage where you don't know what's behind the wall yet, for instance — and almost never appropriate for a planned remodel.

The "what's included and excluded" part is where bids actually diverge. Two $42,000 kitchen bids can describe completely different projects: one assumes you're providing the appliances, one assumes the contractor is sourcing them; one includes painting, one doesn't; one includes electrical panel upgrade, one excludes it as "additional work as needed." Until both bids itemize materials by brand and grade, allowances by line item, and exclusions explicitly, you are not comparing prices — you're comparing different projects that happen to have dollar signs in front of them. We covered the scope-discipline problem at length in how many contractor quotes you should get.

Red flags: a one-page bid that says "kitchen remodel — $42,000," refusal to break out allowances, vague exclusions like "as required."

Get in writing: itemized scope of work as a contract exhibit, with materials specified by brand and grade, allowances broken out by category, and an explicit exclusions list.

5. Who pulls the permits, and who handles inspections?

The contractor should pull permits in their own name. This is non-negotiable for any work that requires one.

When a contractor pulls a permit, their license is on the line for the work. They have a direct legal incentive to make sure it passes inspection. When you pull the permit as the homeowner, the liability falls on you — the contractor is just labor, and if the work fails inspection, you're the one the city is going to come after. Some contractors will push the permit-pulling onto the homeowner specifically because they're not licensed for the work, or because their license has issues that would surface during permit review.

The exception is genuinely small work below your jurisdiction's permit threshold. Replacing a faucet doesn't need a permit. A bathroom gut renovation does. If you're not sure where the line falls, your local building department's website will list it.

Red flags: "You can pull it as the homeowner, it's faster that way," "We don't usually pull permits for this kind of work," "The inspector and I have an understanding."

Get in writing: which party pulls each permit, who pays the permit fees, who schedules inspections, and a clause requiring final inspection sign-off before the final payment is released.

6. Who will actually be on-site doing the work — your employees or subcontractors? If subs, are they licensed and insured, and how do you vet them?

Most contractors use a mix. The kitchen GC has employees doing demo and finish carpentry, then subs out the plumbing, electrical, and tile. There's nothing wrong with that — most trades are deep enough that hiring a specialist is the right call. The question is whether the subs are vetted and covered.

Ask specifically: are the subs licensed in their respective trades? Are they covered under your general contractor's insurance, or do they carry their own? Has the GC worked with them before, or are they being sourced for your project specifically?

The answer tells you whether you're hiring a real general contractor — someone with a stable trusted-trade network they've worked with for years — or a project manager who is going to subcontract everything to whoever's cheapest and available next Tuesday.

Red flags: "I'll figure out who I'm using once we get going," subs who aren't licensed in trades that require it, vague answers about who's responsible if a sub damages something.

Get in writing: named subs where possible, a clause requiring all subs to be licensed and insured, and a clause assigning sub conduct to the GC's responsibility.

7. What happens if you discover hidden conditions once work starts?

In any project that opens up walls, floors, or ceilings, you are going to find things that weren't on the original scope. Subfloor rot, galvanized supply lines, undersized DWV, an electrical panel that can't carry another circuit, framing that doesn't match the as-built drawings, a vent stack that's not where it's supposed to be. The probability of some surprise is essentially 100% on any project older than 1985.

The question isn't whether hidden conditions will come up. It's how the contractor handles them when they do.

A good contractor's answer goes something like: "We stop work, document the condition with photos, write up a change order with the cost and schedule impact, and don't proceed until you've signed it." A bad contractor's answer goes something like: "We just deal with it, and it'll show up in the final bill."

The difference is whether you're driving the budget or watching it from the passenger seat.

Red flags: "It's all baked into the contingency, don't worry about it," "We'll let you know at the end," verbal-only change communication.

Get in writing: a written change-order process, a contingency line item with a defined cap, and a clause requiring written homeowner approval before any work outside the original scope.

Block 3 — Timeline

8. When can you realistically start, and what's the projected completion date?

The "realistically" matters. Almost every contractor will tell you they can start in two weeks. A contractor who is genuinely worth hiring is usually booked four to twelve weeks out. A contractor with immediate availability in peak season is either new, between projects because their last one went badly, or about to take your job and stretch it across three other simultaneous projects.

Ask follow-up questions. How many other active projects do you have right now? How often will the crew be on my site — every day, three days a week, "as needed"? If we sign next Friday, what's the actual first day a crew shows up?

The schedule should include start date, major milestone dates (rough-in inspection, drywall, finish), and a target completion date. A real schedule is not "six to eight weeks." A real schedule has dates.

Red flags: "We can start Monday" in May or June, vague "we'll be here when we're here" answers about crew presence, completion dates that slip during the conversation itself.

Get in writing: a project schedule as a contract exhibit, with milestone dates and a clause defining what counts as "substantial completion."

9. How do you handle delays — weather, supply chain, your other projects, my decisions?

Delays happen. Tile shows up cracked and the next shipment is six weeks out. The crew gets pulled to a flooded job that took priority. You change your mind about the vanity at the worst possible moment.

What you want to know is how the contractor communicates delays, not whether they happen. The right answer involves proactive notification (you find out from the contractor, not from looking at an empty driveway), an updated schedule with the new dates, and an honest explanation of the cause.

This question also gets at whether the contractor is taking on more than they can deliver. If they're going to have your job, two bathrooms across town, and a deck addition all running at once, your project's "delay tolerance" is a function of which one is most important to them — and it's almost never yours.

Red flags: "We don't really have delays," refusal to commit to a communication cadence, schedule explanations that hand-wave past who else they're working for.

Get in writing: a communication cadence (e.g., weekly written status update), a clause defining notice requirements when delays exceed a stated threshold, and damages or rebates for unexcused delays past final completion.

Block 4 — Money

This is the block where homeowners lose the most money, and it's almost always for the same reason: the payment schedule and change-order process weren't pinned down before signing.

10. What's your payment schedule?

The shape of the answer matters more than the percentages. A reasonable payment schedule looks roughly like:

• 10–30% deposit at signing or material order — used to lock in the start date and order long-lead items
• Milestone payments tied to completed phases (demo done, rough-in complete, drywall done, etc.)
• Final payment released only after final inspection sign-off and a completed punch list

The numbers vary by region and project size — a major addition might require a larger deposit because of long-lead structural materials, for instance — but the structure should always tie payments to completed work, not to dates on a calendar.

A contractor asking for 50% upfront is taking on too little risk. A contractor asking for the full amount before completion is taking on no risk at all. Either pattern means that if they walk off the job halfway through, you've already paid them most of what they were going to make, and your incentive to demand a finished project is much weaker than it should be.

Red flags: more than 30% upfront, payments tied to dates instead of milestones, no holdback for the final punch list, requests for cash or wire transfers to personal accounts.

Get in writing: the payment schedule as a contract exhibit, with each milestone tied to a specific completed deliverable and an objective verification method (inspection, photo documentation, owner sign-off).

11. How are change orders priced and approved?

A change order is any modification to the original scope — you decide on a different tile, the contractor finds rotted subfloor, you add a recessed light, the inspector requires a code upgrade you didn't budget for. They are inevitable. The question is how they're handled.

A good change-order process has four parts:

1. Written description of the change before any work begins
2. Cost impact broken into labor, materials, and any markups
3. Schedule impact stated in days
4. Homeowner signature required before work proceeds

A bad change-order process has none of these. Work happens, the cost shows up at the end, and your only options are to pay it or argue.

A particularly nasty trap is the "verbal change order." The contractor mentions on Tuesday morning that the wiring needs to be upgraded, you say "okay, do what you need to," and on Friday a $2,400 line item appears. The fix is simple: nothing happens without a signed paper. If a contractor pushes back on this, that pushback is the answer.

Red flags: verbal-only change orders, "we'll figure out the cost when we know what's involved," markups over 20% on materials, change orders that don't include schedule impact.

Get in writing: a change-order template attached to the contract, a markup percentage stated as a maximum, and a clause requiring written approval before any change-order work begins.

12. Do you provide unconditional lien waivers from all subs and suppliers before final payment?

This one is obscure enough that most homeowners have never heard of it, and it is exactly the kind of question that makes a contractor immediately recalibrate how seriously to take you.

A mechanic's lien is a claim that a contractor or supplier can file against your property if they haven't been paid for work or materials. The wrinkle: even if you paid your general contractor in full, if the GC didn't pay their plumbing sub or their tile supplier, those parties can lien your house. You can end up paying twice.

The protection is unconditional lien waivers — signed documents from each sub and supplier confirming they've been paid in full and waive any right to lien the property. A reputable GC collects these as a matter of course and provides them to you before you release final payment. An evasive answer to this question often signals that the GC is one job behind on paying their subs and is using your deposit to pay for the last project.

Red flags: unfamiliarity with the term, refusal to provide them, "we don't really do that on residential work."

Get in writing: a contract clause requiring unconditional lien waivers from the GC and all subs/suppliers as a precondition to final payment.

13. What warranties do you offer on labor, and what manufacturer warranties apply to materials?

Warranties come in two layers: the manufacturer's warranty on the products themselves (faucets, appliances, flooring, roofing), which is set by the manufacturer and survives whether your contractor stays in business or not; and the contractor's labor warranty, which covers workmanship — the actual installation, framing, finishing.

A typical labor warranty in residential remodeling is one to two years on workmanship, sometimes longer for specific systems (some contractors warranty roofing labor for 5–10 years). What you're looking for is: how long, what's covered, what's excluded, and what the claims process looks like.

The most important thing to know about labor warranties is that they're only as good as the contractor's continued existence. A two-year labor warranty from a contractor who closes shop in eighteen months is worth nothing. This is another reason questions 3 (business longevity) and 12 (lien waivers, which signal financial health) actually matter.

Red flags: verbal-only warranties, warranties that exclude almost every common failure mode, vague claims processes that don't specify response times.

Get in writing: the warranty terms as a contract exhibit — duration, coverage, exclusions, claims process, response time commitment.

Block 5 — Communication and the Day-to-Day

The questions in this block don't sound as consequential as the money questions, but they're the ones that determine whether the project is a livable experience or an eight-week ordeal you remember for the rest of your life.

14. Who is my day-to-day point of contact, and how often will we communicate?

You want one person whose phone you can call. Not "the office," not "whoever is on-site that day," not the GC who responds to texts at 11 p.m. on Sunday because that's the only time he checks them. One name, one phone number, one defined response window.

Equally important: a defined update cadence. The right pattern for most projects is a brief weekly status email or text — what got done this week, what's planned next week, what decisions need to be made, what's running behind. Some contractors do daily logs. Some do nothing unless something goes wrong. The one you want is the one who is proactive enough that you rarely have to ask.

Red flags: "Just text me anytime," no defined update cadence, point of contact who is the owner of a busy company and won't actually be available.

Get in writing: the named point of contact, communication channel, and update frequency as a clause in the contract.

15. How will you protect my property and handle cleanup?

The day-to-day livability questions: where will materials be stored, where will the dumpster go, will dust barriers be installed, which restroom will the crew use, will the site be cleaned at the end of every workday, will floors and finishes outside the work zone be protected with masonite or paper.

These sound minor on a site visit and feel enormous when you're three weeks in, the dust has migrated into closets two floors away, and the crew has been using your downstairs powder room without ever flushing.

Red flags: "We clean up at the end," no plan for dust containment in finish-occupied homes, no plan for material storage in tight properties.

Get in writing: a site protection and cleanup standard as a clause — daily broom-clean, dust barriers at openings to occupied space, designated material storage area, and a final professional cleaning before substantial completion.

The references question that goes after all of these

We've kept this separate from the numbered list because it doesn't belong in the site-visit conversation — it belongs in the homework you do after.

Ask for three references from projects similar to yours, completed in the last twelve to twenty-four months. The recency matters. A reference from 2018 doesn't tell you anything about the contractor's current crew, current capacity, or current quality. A reference from last quarter does.

Then actually call them. The questions worth asking past clients are not the ones that get scripted answers ("Were you happy with the work?") but the ones that get specific stories:

• Did the project come in on the original timeline? If not, by how much, and why?
• Did the final cost match the original bid? If not, what changed?
• How did the contractor handle the first thing that went wrong?
• Would you hire them again for a similar project? Why or why not?
• Is there anything you would do differently if you were starting over with them?

The "first thing that went wrong" question is the most useful one. Every project has at least one. The contractor's response to that one moment tells you more about them than any other piece of evidence you can collect.

What to put in the contract regardless of how good the verbal answers were

Eight things have to be in the contract before you sign. Missing any one of these is a reason to delay signing, not a reason to "trust the process":

1. Detailed scope of work with materials specified by brand and grade, allowances broken out, and an explicit exclusions list
2. Total contract price broken into labor, materials, allowances, and contingency
3. Payment schedule with milestones tied to completed work, not calendar dates
4. Project schedule with start date, milestones, and substantial completion date
5. Change-order process with a written-approval-before-work clause and a stated markup cap
6. Lien waiver requirement from GC and all subs/suppliers as a precondition to final payment
7. Insurance and license representations with policy numbers, dollar limits, and a maintain-coverage-through-completion clause
8. Warranty terms for both labor and materials, including duration, coverage, exclusions, and claims process

If any of these are missing from the contract you're handed, the right move is to email a redline back rather than sign and hope. Reputable contractors expect this. The ones who push back are sorting themselves out of consideration.

What to do when the answers are good but you still aren't sure

You won't get clean answers to all fifteen questions from every contractor. Almost no real-world site visit produces a perfect transcript. What you want is a pattern: most answers are direct and specific, willingness to put things in writing is high, and the contractor doesn't get defensive when you push on the money or scope questions.

If you're getting good answers but you can't quite tell if the price is fair, that's not a question your gut can answer — it's a question for a localized cost estimator like Homesage.ai or Handoff, which compare your scope against ZIP-code-localized pricing built from real residential project data. Run the bid through one of those before you sign and you'll know within a few percent whether the number is in the right zone.

If you're getting good answers from one contractor but only have one bid in hand, you're also still under-equipped to sign. The whole point of multiple bids is that the second and third bids tell you which questions to ask the first one harder. Three bids built from the same scope of work — with these fifteen questions answered consistently across all three — is the floor for a confident decision. We covered why and how to get there in how many contractor quotes you should get.

What this means for the rest of your project

Here's the honest version of what these fifteen questions are doing: they're converting a sales conversation into an interview. Every contractor on the planet can do a charming site visit. The interview is what separates the ones who can also run a project on time, on budget, and inside the bounds of the contract from the ones who can't.

The bottleneck for most homeowners isn't asking the right questions — it's getting in front of enough qualified contractors to ask them. Three site visits requires three contractors who returned your call, scheduled a visit, showed up, and submitted a real bid. The industry-wide contractor non-response rate means you typically have to reach out to seven to ten to land three.

That's the problem we built ClearQuote to solve. You submit your project once, our AI calls and texts qualified local contractors on your behalf, follows up until they engage, and delivers real, comparable bids back into your dashboard. The fifteen questions above are what you ask the contractors who actually show up. We get them to show up.

Let AI handle the outreach.

ClearQuote contacts contractors for you, shares your project details, and gets you quotes without the phone tag.
