How to Find and Vet a Contractor

15 min read · Updated May 2026

Most first-time remodelers pick the wrong contractor not because they did not try, but because they did not know what to look for. The contractor decision is the highest-stakes choice in your entire remodel, because a bad contractor can cost you 20 to 50 percent of project budget in delays, rework, and disputes. Yet most first-timers pick based on a friend's recommendation, a Yelp rating, or whichever quote came in lowest. None of those signals correlate well with quality. This article gives you a framework that prevents about 90 percent of contractor problems.

We will cover where to find contractors and the order to use, the 7 questions for the first call, how to verify licensing and insurance, the 12 red flags that mean walk away, contract clauses that protect you, payment schedules that prevent disaster, communication norms during the project, and how to fire a contractor mid-project if it comes to that.

Where to find contractors (and the order to use)

The reliability of contractor leads varies dramatically by source. Here is the rough hierarchy.

1. Referrals from neighbors with completed projects. The single most reliable source. Walk through your neighborhood, knock on doors of houses where you can see recent work, and ask the homeowners about their contractor experience. Most people are happy to talk. You get unfiltered feedback from someone with no financial incentive.

2. Recommendations from real estate professionals. Agents have long-term relationships with contractors and care about quality because their reputations are on the line at resale. Local agents who know the area well are often the best second source after neighbor referrals.

3. Recommendations from architects or designers. If you are working with a designer, they probably know which local contractors execute well and which produce problems. Their recommendations are usually high quality because they work with the contractor again on future projects.

4. Local building department lists. Most building departments maintain lists of contractors who have pulled permits in the past year or two. This is a useful starting point because every contractor on the list is at least permitting their work, which is one filter.

5. Online review sites, carefully filtered. Google reviews, Yelp, Houzz. Read reviews critically. Five-star aggregates are less useful than reading the actual text of recent reviews, especially the 2 to 3 star reviews where dissatisfied clients describe specific problems. Look for patterns.

6. Lead-generation services (HomeAdvisor, Thumbtack, Angi). Use with caution. Contractors pay for leads on these platforms, which often means they need to pad estimates to recoup the lead cost. The contractors are also self-selected for needing leads, which is not necessarily a positive signal.

7. Random internet finds, door-to-door solicitations, mailers. Avoid. Door-to-door solicitors are particularly risky.

The 7 questions to ask in the first call

The first call is a screening conversation, not a sales pitch. You are trying to determine in 15 to 20 minutes whether this contractor is worth a site visit. Ask these 7 questions, in this order.

1. "How long have you been in business in this area?" Five years minimum, ideally 10 plus. Brand-new businesses can be fine, but they carry more risk because the track record is short.
2. "Are you licensed and insured in this state?" Get the license number on the phone. Verify it after the call using the state contractor licensing board's online lookup.
3. "What is your specialty?" Some contractors specialize in kitchens, others in bathrooms, others in whole-home renovations. The right contractor for your project is one who does many projects of your specific type.
4. "What is your current schedule? When could you start?" Reputable contractors are usually booked 2 to 6 months out. Anyone who can start next week is either between jobs (sometimes fine), new to the business (more risky), or in trouble.
5. "What is your typical payment schedule?" Look for milestone-based payments with a hold-back at completion. See the payment section below.
6. "Can you provide references from three recent projects similar to mine?" Three is the right number. Recent (within 12 months) is important. Similar in scope is important.
7. "What is your change order process?" Look for written change orders, with cost and schedule impact, signed by both parties before work proceeds.

If the contractor cannot answer these 7 questions clearly, or gets defensive, that is itself useful information. Move on to the next candidate.

Licensing and insurance verification

Every state has a contractor licensing board. Find yours via search ("[your state] contractor license lookup") and verify the license number the contractor provided. The lookup typically shows:

• License status (active vs. inactive vs. suspended)
• Expiration date
• Bonding status
• Disciplinary history or active complaints
• Classification (what types of work the license covers)

Insurance verification is the second step. Ask for a certificate of insurance (COI) showing general liability and workers' compensation. The contractor's insurance broker should send this directly to you. Both coverages are essential. General liability protects against property damage; workers' comp protects you against liability if a worker is injured on your property.

Coverage amounts vary by state and project size, but $1 million general liability and standard workers' comp are typical. Anything below $500,000 general liability is worth questioning.

Verify directly with the insurance carrier (not just the contractor's certificate) for any project over $25,000. The certificate could be expired or fraudulent; the carrier can confirm current coverage.

The 12 red flags that mean walk away

1. Pressure to sign quickly or pay a large deposit upfront. Reputable contractors do not pressure clients.
2. Cash-only or off-the-books pricing. Usually means no permits, no insurance, no warranty, no accountability.
3. Cannot or will not provide a license number on request. Disqualifying.
4. References cannot be verified or are not provided. Pattern of fake references.
5. No written contract or refuses to put scope in writing. Disqualifying.
6. Door-to-door solicitation following a storm or disaster. A specific scam pattern.
7. Quote dramatically below the others. Almost always missing scope or planning to make money on change orders.
8. Vague answers about timeline. "Pretty quick" or "shouldn't take too long" instead of specific weeks.
9. Asks you to pull permits in your name. Usually means they cannot pull permits themselves due to licensing issues.
10. No physical business address, only a phone or PO box. Difficult to find if there is a problem later.
11. Multiple recent business names or recent state-board complaints. Pattern of name changes to escape reviews.
12. Bad-mouths other contractors. Professional disagreement is fine; persistent bad-mouthing is a sign of insecurity or inexperience.

Any one of these is reason to be cautious. Two or more is reason to walk away regardless of price.

Contract clauses that protect you

The written contract is your primary protection during and after the project. Several clauses should be present in any contract you sign.

Detailed scope of work. Specific list of work to be done, materials to be used (by brand and model where possible), and work that is explicitly out of scope. This prevents most disputes about what was promised.

Total contract price and payment schedule. Specific dollar amounts tied to specific milestones. Not "due upon request" or "due weekly."

Change order process. All changes in writing, with cost and schedule impact, signed by both parties before work proceeds. Verbal change orders are a major source of disputes.

Start and completion dates. Specific dates, with provisions for legitimate delays (weather, supply chain) defined narrowly.

Warranty terms. Most quality contractors offer 1 year on workmanship and pass through manufacturer warranties on materials. Some offer longer warranties on specific items.

Lien release language. Contractor must provide lien releases from subcontractors and material suppliers as condition of final payment. Without this, subcontractors can place liens on your property if the contractor fails to pay them, even if you paid the contractor in full.

Termination clauses. Conditions under which either party can terminate the contract, and what happens financially if termination occurs. See the firing section below.

Dispute resolution. How disputes get handled. Mediation before litigation is common.

Sample contract language for change orders: "Any changes to the scope of work shall be documented in a written change order signed by both parties before the change work begins. The change order shall specify the cost, schedule impact, and revised contract total."

Payment schedules: the never-pay-more-than rule

Payment schedules are where most contractor relationships go wrong. The rule we recommend: never pay more than 33 percent before substantial work begins, and always hold back at least 10 to 15 percent until the punch list is complete.

A reasonable payment schedule for a typical mid-range remodel:

• 10 to 25 percent at contract signing (deposit to reserve schedule and order materials)
• 25 to 30 percent at start of demolition
• 25 to 30 percent at "rough-in complete" milestone (framing, electrical rough, plumbing rough)
• 15 to 20 percent at "finishes substantially complete" milestone
• 10 to 15 percent at punch list completion

Watch for contractors who want 50 percent upfront. This is a major red flag. The only legitimate reason for a high deposit is a project requiring expensive material orders that ship before construction starts, and even then, 35 to 40 percent should be the maximum.

The hold-back at completion is your single most useful tool. As long as you hold 10 to 15 percent, the contractor has financial incentive to finish the punch list. Once you pay everything, that incentive disappears.

Communication norms during the project

Set communication expectations at the contract stage. Three things to establish upfront.

First, who is your point of contact? On larger projects, the owner of the company may sell the job and then disappear once construction starts, with a foreman or project manager taking over. Know who you will actually be dealing with daily.

Second, how often will you communicate? Weekly check-ins are typical for substantial projects. Some contractors prefer daily updates; some prefer "I'll call you if anything comes up." Decide what works for you and put it in writing.

Third, how are decisions documented? Verbal decisions disappear from memory in 48 hours. Important decisions should be emailed or texted as confirmation. "Per our conversation today, we agreed to..." kind of language. This protects both parties.

Reference-call questions: what to actually ask

Most first-timers call contractor references and ask "were you happy with the work?" That question always produces the same answer: yes. The reference would not have been provided otherwise. The useful questions are more specific.

1. "Did the project finish on the original timeline? If not, what caused the delay?" Slippage of 1 to 2 weeks is normal; significant delays signal organization or capacity problems.
2. "How many change orders did you have, and what were they?" A pattern of change orders the homeowner did not initiate suggests scope problems in the original quote.
3. "How was communication during the project?" Specifically: did the contractor respond to texts and calls promptly, surface problems early, document decisions clearly?
4. "Was the final price close to the original quote? If not, by how much?" 5 to 10 percent over is normal; 25 percent over is a yellow flag worth probing.
5. "How was the cleanup and the punch list process?" Many contractors do strong work and then fade on the finishing details. The reference can tell you which kind your candidate is.
6. "Would you hire them again? Honestly?" Best closing question. Listen for hesitation.

Call all three references, not just one. Patterns become clear across three conversations that single calls can hide.

The site visit: what to look for

After the first call and reference checks, invite the top one or two candidates for a site visit. The visit is two-way. You are evaluating them; they are scoping the work and pricing accordingly. Three signals to watch for during the visit.

First, do they take measurements and notes? Contractors who walk through, glance around, and quote from memory are guessing. Contractors who measure, photograph, and write things down are estimating from data. The second group's quotes are usually more accurate.

Second, do they ask diagnostic questions about your home? "When was this kitchen last updated?" "Is the panel original to the house?" "Do you know if this wall is load-bearing?" Contractors asking these questions are thinking about the actual project. Contractors who only ask "what are you looking to spend?" are pricing based on your budget, which is the opposite of what you want.

Third, do they raise issues you had not considered? A good contractor will spot the dated electrical panel, the questionable subfloor under the existing tile, the slope of the existing drain that may affect your layout plans. A contractor who tells you about a problem you did not know about is probably worth hiring; that knowledge prevents surprises mid-project.

How to fire a contractor mid-project

Sometimes the relationship breaks down. The contractor stops showing up, work quality drops, communication breaks down, or money becomes a fight. Firing a contractor is messy but sometimes necessary.

The steps, in order.

1. Document the specific problems in writing. Dates, photos, copies of communication. You need a record if disputes follow.

2. Send a written notice of the issues. Email or certified mail. Give a specific deadline for the contractor to address the problems, typically 7 to 14 days.

3. If problems are not addressed by the deadline, send a termination notice. Reference the original notice, state that you are terminating per the contract's termination clauses, and stop further payments.

4. Document the state of the project on the day of termination. Photos, video, list of work completed and work remaining. You will need this for the financial settlement and for the next contractor.

5. Resolve outstanding payments based on work completed. Pay for work actually done (with documentation); withhold payment for work not done. Expect disputes about what counts as completed.

6. Hire a replacement contractor for completion. The replacement will charge a premium because finishing someone else's work is harder than starting from scratch. Budget for this.

Most contractor disputes do not have to reach termination. Most reach termination because the warning signs were ignored too long.

Two warning signs that most homeowners ignore for weeks before they should. First, missed days without communication. A contractor who skips a workday is normal; a contractor who skips two days in a row without calling is signaling either disorganization or trouble with another project. Address it the same day, in writing. Second, quality concerns that the contractor dismisses rather than addresses. If you raise a quality issue and the contractor says "that is fine, that is how it is done," check with another contractor or a designer before accepting the answer. Sometimes it really is fine. Sometimes it is not, and getting confirmation from a third party shifts the conversation back into your favor.

Firing is the last resort. Most issues can be resolved with clearer documentation and tougher conversations, neither of which feel pleasant but both of which beat a half-finished project sitting unworked for weeks.

Frequently asked questions

The takeaway

Vetting a contractor takes 5 to 10 hours of work spread across 2 to 3 weeks. That time investment is the single highest-return work you can do on your remodel. The right contractor turns a stressful project into a manageable one. The wrong contractor turns the same project into a months-long ordeal with financial damage that lingers.

Do the vetting. It is not optional. Every step in this article exists because we have read reader emails describing what happens when the step is skipped, and the answer is always the same: the project costs more, takes longer, and ends in a worse outcome than careful upfront work would have produced.
