How to Research a Contractor Online Before You Call

Why a 10-Minute Online Search Can Save You From a Costly Mistake

What does contractor fraud actually look like?

Contractor fraud doesn’t usually start with someone acting suspicious. It starts with a polite handshake, a professional-looking estimate, and a story that sounds completely reasonable. The contractor seems fine. The price seems right.

Then the work starts — or doesn’t — and problems surface.

According to the National Insurance Crime Bureau, contractor fraud costs American homeowners billions of dollars each year, with average losses ranging from $3,000 to over $15,000 per incident. Roof scams, foundation repair cons, HVAC replacements with used parts — these aren’t rare. They happen in every zip code.

What makes contractor fraud so damaging isn’t just the money lost. It’s the work that was never done, the permits that were never pulled, the code violations that create liability for the homeowner. In many cases, the homeowner is left holding the bag even after the contractor has disappeared.

The good news: a basic online search catches the majority of contractors who have a documented history of problems. Most bad actors have left a trail. You just need to know where to look.

Why do so many homeowners skip the research?

The most common reason homeowners skip online research is that they don’t know what public records exist or how to find them. They know about Google reviews and maybe the BBB. But state license board lookup tools, county permit databases, and court records search portals are almost entirely invisible to the average homeowner.

The second reason is that research feels complicated. In reality, the tools are simple and almost everything is free. You don’t need a lawyer, a private investigator, or a paid background check service to run a solid contractor check.

This guide walks you through every source, step by step. By the end, you’ll know how to find information that most homeowners never think to look for — and you’ll be able to run a complete research sequence in about 30 minutes.

What’s the real cost of not researching?

Consider what you’re protecting. A roof replacement runs $8,000 to $20,000. A full HVAC system costs $6,000 to $14,000. A bathroom remodel can reach $25,000.

These are not small purchases, and unlike buying a car or a refrigerator, hiring a contractor means giving someone extended access to your home, your systems, and in many cases your family’s daily life.

When a contractor turns out to be unlicensed, the consequences extend beyond poor workmanship. Your homeowner’s insurance may not cover damage caused by unlicensed work. You may face re-inspection costs when you sell. You may even be held liable for injuries to workers on your property.

Thirty minutes of online research before the first phone call is one of the highest-return activities available to any homeowner. Part of that research is understanding what your state requires — and whether the contractor actually meets the standard.

The 7 Sources to Check Before Calling Any Contractor

Which sources actually matter when you research a contractor online?

There are dozens of places where contractor information might exist online — but seven sources consistently produce the most reliable, actionable data. Each one covers a different piece of the picture. No single source is complete on its own.

Think of it as a background check made up of layers. Google and BBB are the surface layer — visible, but limited. The deeper layers — licensing boards, permit databases, court records, and Secretary of State filings — are where the most important information hides. Most homeowners never dig past the surface.

Here is a brief overview of the seven sources, with deep dives in the sections that follow:

• Google: Surface complaints, news coverage, forum posts, and pattern-of-problem searches using specific search operators.
• Better Business Bureau (BBB): Complaint history, resolution patterns, and accreditation status. Read more in our guide on how to read a contractor BBB report.
• State Licensing Board: License status, expiration date, bond and insurance requirements, and disciplinary history.
• County Permit Records: Whether the contractor actually pulls permits, permit history, and inspection results. Details in our guide on how to check a contractor’s permit history.
• Court Records: Civil lawsuits, small claims judgments, mechanics liens, and criminal records in some jurisdictions.
• Social Media: Business page activity, customer comments, complaint patterns, and how the contractor responds publicly.
• Secretary of State: Business registration status, DBA names, company formation date, and active/inactive status.

Each section below walks through how to use these sources step by step. To put the whole picture together — including what online reviews really tell you and what they don’t — see our companion article on what contractor reviews really tell you.

How to Search Google Like an Investigator

Why does a basic Google search miss most contractor problems?

When most people Google a contractor, they type the business name and look at the top results — usually the contractor’s own website, a Google Maps listing, and maybe a few review links. That’s the surface. The problems are rarely on the surface.

Complaint threads live on local Facebook groups, Nextdoor, home improvement forums, and small news sites that don’t rank well on basic searches. Court filings and licensing actions appear on government pages that also don’t rank well. To find this material, you need to use search operators — specific commands that force Google to narrow or expand its results in ways a basic search won’t.

The approach isn’t complicated. It’s a matter of knowing which phrases to pair with the contractor’s name, and then systematically running through the list. Ten minutes of targeted Google searching beats an hour of casual browsing every time.

What Google search strings actually surface contractor complaints?

Start with the contractor’s full business name in quotes. Then run each of the following variations:

Run these searches one at a time and scan the first two pages of results for each. You’re looking for complaint threads, news articles, forum discussions, government actions, or any pattern suggesting a history of problems. One unhappy customer is usually noise. Three or more unhappy customers across unrelated platforms is a signal.

How do you search a contractor’s license number on Google?

Once you have the contractor’s license number (obtained from their estimate, business card, or the licensing board), search it directly in Google. The format looks like this:

Searching the license number directly sometimes surfaces complaints, licensing board actions, or forum posts that are written about the license rather than the business name. It also helps you verify that the name on the license matches the name the contractor gave you.

What if the contractor has a very common name?

For contractors with common names or generic business names, add the city or state to narrow results. For example: “Smith Plumbing” Dayton Ohio complaint. You can also search for the contractor’s phone number in quotes — phone numbers often surface linked business names, complaint boards, and reverse-lookup profiles that a name search alone won’t find.

Don’t overlook image search. Searching the contractor’s business name in Google Images sometimes surfaces logo reuse across multiple business names, which may indicate a pattern of starting fresh after complaints under a prior name.

State Licensing Boards: What They Show and How to Use Them

Why is the state licensing board your most important stop?

Your state licensing board is the only source that gives you official, government-verified information about a contractor’s credentials. It is not a review site. It is not an opinion platform. It is a regulatory record that the contractor is legally required to maintain.

A licensing board lookup tells you whether the license is active or expired, the exact legal name the license was issued under, the license type (general contractor, electrical, plumbing, HVAC, roofing — depending on your state), the expiration date, and in many states, whether there have been disciplinary actions, complaints, fines, or license suspensions.

This information is free. Every state with a contractor licensing requirement — and most states do have some form of it — provides a public license lookup tool online. Finding the right URL is usually as simple as Googling “[your state] contractor license lookup.”

What exactly should you look for in a licensing board search?

When you pull up a contractor’s license record, go through these checkpoints systematically:

• Active status: The license must be active — not expired, suspended, or revoked. An expired license may indicate a contractor who let required continuing education or insurance lapse.
• License type match: The license type should match the work you’re hiring them for. A general contractor license doesn’t always cover specialty trades like electrical or HVAC.
• Name match: The legal name on the license should match the name on the contractor’s estimate and business card. Discrepancies deserve explanation.
• Disciplinary history: Many state boards list complaints, investigations, fines, and suspensions. Even if the contractor’s license is currently active, past disciplinary action tells you something important about their history.
• Bond and insurance confirmation: Some state boards confirm whether the contractor’s required bond and insurance are current. This is different from the contractor simply claiming to be insured — it’s verified status.

What happens if a contractor tells you their state doesn’t require a license?

Some contractors say this because it’s true — a handful of states have minimal licensing requirements for general contractors, particularly for residential work below a certain dollar threshold. But “the state doesn’t require it” is not the same as “there are no licensing requirements.”

Many trades — electrical, plumbing, HVAC — are licensed at the state level even in states with weak general contractor licensing. And some states license at the county or city level rather than the state level, meaning a state-level search won’t find anything even for a fully licensed contractor.

Ask the contractor specifically: “What license do you hold, what number is it, and which agency issued it?” A legitimate contractor answers that question without hesitation. A contractor who hedges or changes the subject deserves more scrutiny, not less.

County Permit Records: How to Find Them and What They Reveal

Why do permit records tell you more than a license check alone?

A license tells you a contractor met the requirements to work legally. A permit record tells you whether the contractor actually works legally — on real jobs, in the real world, right now. These are two very different things.

Pulling permits is a legal requirement for most significant home improvement work — structural changes, electrical panel upgrades, HVAC replacements, plumbing modifications, additions. A contractor who consistently skips permits is either cutting corners to win bids (which you pay for through unpermitted work that creates problems when you sell) or working without the required credentials.

County permit databases are public record in virtually every jurisdiction. Most counties now have them online, searchable by contractor name, license number, or address. They don’t require registration and they don’t cost money. Yet almost no homeowner thinks to look.

How do you find your county’s permit lookup tool?

Start by Googling “[your county name] building permit search” or “[your city name] permit records online.” Most results will point you directly to the county building department or a third-party permit search portal used by many jurisdictions.

Once you’re in the system, search the contractor’s business name and license number. Look at the volume of permits pulled over the past two to three years. A busy legitimate contractor will have a consistent history.

Look at inspection results — passed inspections confirm the work met code. Failed inspections followed by corrections are normal. Failed inspections with no follow-up are a red flag.

If a contractor has pulled zero permits in your county over the last three years despite claiming to be busy, ask about it directly. They may work primarily in neighboring counties — which you can also check. Or they may be routinely skipping permits, which tells you something important about how they operate.

What do permit records reveal that a contractor wouldn’t volunteer?

Permit records can show jobs that were permitted but never had a final inspection — meaning the work was started but never officially closed out. This is a red flag for a contractor who abandons projects or leaves work incomplete. They can also show stop-work orders issued by the building department, which indicate serious code violations discovered mid-project.

In some jurisdictions, permit records include the value of the permitted work. This gives you a rough calibration tool — if a contractor claims to do $50,000 projects regularly but their permit records only show $5,000 jobs, the discrepancy is worth asking about.

For a complete walkthrough of how to pull and interpret permit records, including what stop-work orders mean and how to read inspection histories, see our in-depth guide on how to check a contractor’s permit history and why it matters.

Court Records and Lawsuits: What to Look For

Are contractor court records actually available to the public?

Yes — civil court records are public record in every U.S. state. That means lawsuits, judgments, and in many cases mechanics liens filed against a contractor are searchable by anyone. Most state court systems have a free online portal for searching civil case records, and most counties have searchable records at the county clerk level.

You don’t need an attorney to run a court records search. You don’t need a paid background check service. You need the contractor’s full legal name, the name of their business entity, and access to your state’s court search portal.

A single lawsuit over a span of years is not necessarily alarming — contractors who do significant volume will occasionally end up in disputes. What you’re looking for is pattern: multiple lawsuits across multiple years, cases involving homeowners specifically, or cases involving fraud, abandonment, or failure to pay subcontractors.

How do you search court records for a contractor?

Start with your state’s unified court system website. Most states have a central portal — search Google for “[your state] court records search” or “[your state] public court records online.” Common portals include Ohio’s CourtView, Florida’s eClerks, and various state-specific court information systems.

Search using all of the following:

• The contractor’s full personal name (e.g., John Michael Smith)
• The business’s legal name (e.g., Smith Roofing LLC)
• Any DBA names you’ve found through Secretary of State research
• The contractor’s license number, if the court system allows that search field

For each result, look at whether the case was as plaintiff or defendant, what the case type was, and how it was resolved. Satisfied judgments are different from unsatisfied ones. Cases dismissed in the contractor’s favor are different from default judgments entered against them because they didn’t show up.

What are mechanics liens and why do they matter for contractor research?

A mechanics lien is a legal claim filed by a subcontractor or supplier when a contractor fails to pay them for work already completed. When a general contractor doesn’t pay the electrician, the plumber, or the lumber yard, those parties can file a lien against the property where the work was done — which ultimately threatens the homeowner.

A history of mechanics liens filed against a contractor’s projects is a serious red flag. It means subcontractors regularly aren’t getting paid, which often means the contractor is cash-flow challenged or financially unreliable. Mechanics liens are recorded at the county recorder’s office and are searchable in most jurisdictions through the same courthouse or county clerk portals used for civil court records.

If you find a pattern of mechanics liens, ask for clarification — but weight it heavily. A contractor who can’t pay their subs is a contractor who will use your deposit to survive rather than to buy your materials.

Social Media as a Contractor Research Tool

What does a contractor’s social media presence actually tell you?

Social media is not just a place to see pretty before-and-after photos. For a careful researcher, it’s a window into how a contractor runs their operation, how they respond to criticism, and how their community actually perceives them.

A contractor’s Facebook Business Page, in particular, often contains unfiltered feedback. Unlike Google or Yelp, where reviews are moderated and the contractor can flag unfavorable ones, Facebook comments on posts can show patterns of complaint, confusion, or outright accusation. Comments saying “you still owe me money” or “you never finished my bathroom” sitting under a promotional post are not something a contractor can easily erase.

Don’t limit your search to the contractor’s own pages. Search for the contractor’s business name in the Facebook search bar and look for mentions across local community groups, neighborhood forums, and home improvement groups in the area. Nextdoor is another powerful source — homeowners post contractor warnings there that never make it to Google or the BBB.

How do you interpret what you find on a contractor’s social media?

Look at the volume and recency of activity. A contractor whose last post was three years ago but who is presenting themselves as actively in business raises questions about continuity. A business page with no reviews, no completed project photos, and no engagement may be a recently created profile designed to look established when the contractor is anything but.

Pay attention to how the contractor or their representatives respond to negative feedback. A response that is dismissive, defensive, or aggressive tells you something important about how they’ll handle a dispute on your job. A thoughtful, professional response — even to a harsh complaint — is a positive signal.

Look at the photos carefully. Are project photos consistent in quality and scope with the kind of work you’re planning to hire them for? Are there recurring photos that appear on multiple sites under different business names? Reverse-image searching a few photos is worth the two minutes it takes if you’re about to write a large check.

What should you search on Nextdoor and local Facebook groups?

Search the contractor’s business name directly in Facebook Groups you’re a member of, and use Nextdoor’s search function the same way. Also search “contractor warning” or “contractor avoid” in local groups and scan for mentions of the business name in those threads.

Posts like these tend to be highly specific, naming the contractor, the job, the dollar amount, and the outcome. A single warning post from two years ago may be a resolved dispute. Multiple warning posts from different people over different years — that’s the kind of pattern that should send you to the next contractor on your list.

Secretary of State Business Registration: Finding DBA Names and Business History

Why should you check the Secretary of State before hiring a contractor?

Every business operating as a legal entity — LLC, corporation, or registered DBA — is required to file with the Secretary of State in the state where it operates. These filings are public record, searchable online, and free to access. Yet most homeowners have never heard of this resource.

A Secretary of State business search tells you things that no review site or licensing board will tell you: exactly when the business was formed, whether it is currently active or has been dissolved or revoked, who the registered agent of record is, and whether the contractor has operated under multiple different business names over time.

The significance of this last point cannot be overstated. A contractor who has a history of forming a business, accumulating complaints or judgments, dissolving that business, and immediately forming a new one under a slightly different name is engaging in a pattern commonly associated with contractor fraud. Secretary of State records are how you catch it.

How do you run a Secretary of State business search?

Go to your state’s Secretary of State website and locate the business entity search tool. In most states this is labeled “Business Search,” “Business Entity Search,” or “Business Filings.” Enter the contractor’s business name and review the results.

Look at the date of formation. A company formed three months ago that is presenting itself as having decades of experience deserves scrutiny. Look at the status — “Active,” “Good Standing,” “Dissolved,” “Revoked,” or “Cancelled” all mean something specific. A revoked or dissolved status while the contractor is still actively soliciting work is a significant red flag.

Also search the contractor’s personal name as the registered agent or organizer. This can surface all of the entities they have been connected to — past businesses, sister companies, and prior entities that may have been dissolved under problematic circumstances. Follow every thread you find.

What is a DBA and why does it matter for your research?

DBA stands for “doing business as” — it’s a trade name that a contractor operates under that is different from their legal entity name. A contractor’s legal entity might be “Warner Home Services LLC,” but they advertise and do business as “Premier Roofing Experts.” Both names should be searchable, and both should be checked across all the research sources.

DBA registrations are filed either with the Secretary of State or at the county level, depending on the state. In some cases, they’re registered at both. When you find a DBA name, run the same complete search sequence for that name: Google complaint searches, BBB lookup, court records, permit history, and social media.

Contractors who have burned through multiple DBA names while keeping the same underlying entity — or vice versa — are worth extra scrutiny. Ask directly: “What other business names have you operated under?” Legitimate contractors answer without hesitation. Evasion on that question is itself a signal.

Putting It All Together: The 30-Minute Contractor Research Sequence

What is the most efficient order to run contractor research?

When you have a contractor’s name and business, run the research in the following order. This sequence is designed to work from the fastest checks to the slower ones, and to feed later searches with information uncovered in earlier steps.

Minutes 1–5: Identity and Google check. Confirm the contractor’s full legal name, business name, license number, and phone number. Run your Google search strings: business name + “complaint,” + “scam,” + “lawsuit.” Scan the first two pages of each. Flag anything that looks like a pattern.

Minutes 6–10: Secretary of State lookup. Search the business name and the contractor’s personal name. Confirm active status, formation date, and any linked entities or DBA names. Note any prior business names to fold into your other searches.

Minutes 11–15: State licensing board search. Enter the license number and confirm active status, correct name, license type, and expiration date. Read the full record for any disciplinary notes, complaints, or investigation history. If the board shows current bond and insurance status, verify that too.

Minutes 16–20: BBB and court records. Search the BBB for the business name and check complaint count, complaint type, and resolution pattern. Then run a court records search using all known names — personal name, business name, and any DBA names.

Note case types and outcomes. Flag anything involving homeowners, fraud, abandonment, or failure to pay.

Minutes 21–25: County permit lookup. Search the contractor’s business name and license number in the county permit database. Review permit volume over the past three years, inspection results, and whether there are any open permits that never received a final inspection. Note any stop-work orders.

Minutes 26–30: Social media and Nextdoor. Search Facebook, Instagram, and Nextdoor for the contractor’s business name. Read through any community mentions. Check how the contractor responds to public criticism.

Look for any complaint patterns that didn’t surface elsewhere.

What should you record as you research?

Keep a simple running document as you go. For each source, note: what you searched, what you found, and whether the finding is neutral, positive, or a flag. By the end of the sequence, you’ll have a clear picture of the contractor’s record across all sources.

A contractor who passes cleanly across all seven sources — active license, clean court record, consistent permit history, no meaningful complaints — is in a dramatically different risk category than one who has three complaint threads on Google, a dissolved prior business, and a court judgment from 2022. The research produces a calibrated picture, not a yes/no answer.

Bring your research notes to the first meeting with the contractor. Use them as a basis for direct questions: “I noticed a court case from 2021 involving your prior business — what happened there?” A contractor who is offended by a professional question like that is not someone you want managing your home project.

For context on how to verify references once you’ve narrowed your list, see our article on how to verify a contractor’s references the right way. Reference checks and online research together form the complete picture.

What to Do When You Find Something Alarming

Does every red flag mean you should walk away?

Not automatically. The appropriate response depends on what you found, how recent it is, and whether it represents a pattern or an isolated incident. One complaint filed with the BBB five years ago that was resolved in the contractor’s favor is very different from three active court judgments and a revoked license.

Context matters. A contractor who has been in business for 20 years and done hundreds of projects will occasionally have a dispute — that’s not disqualifying. What you’re looking for is whether problems appear to be systemic, recurring, and unresolved. Isolated incidents from years ago, followed by a clean record since, often indicate a contractor who learned from mistakes and improved.

The most useful tool at this stage is a direct conversation. Bring your specific findings to the contractor — calmly and professionally — and ask them to explain. A contractor with nothing to hide explains. A contractor who responds with hostility, dismissal, or evasion has told you something important through their reaction.

Which findings should be automatic disqualifiers?

Some findings should end the conversation without exception:

• Revoked or expired license: No valid license means no valid contractor. There are no exceptions. A claim that “the paperwork is in process” is not sufficient — verify active status before proceeding.
• Active unsatisfied court judgments related to homeowner work: This indicates ongoing legal liability and suggests the contractor has a documented history of not fulfilling obligations.
• Multiple mechanics liens across multiple projects: A single lien may be a dispute. A pattern of liens means the contractor routinely doesn’t pay subcontractors — and your materials money is at risk.
• Evidence of the “business name shuffle”: A contractor who has operated under three business names in five years, each dissolved after accumulating complaints, is engaged in a known fraud pattern.
• Confirmed fraud complaints from multiple independent sources: If you find warning posts on Nextdoor, a complaint-heavy BBB file, and a fraud-related court case, that convergence is not coincidence.

What are the best ways to report a contractor who appears to be operating fraudulently?

If your research reveals what appears to be an actively fraudulent contractor — particularly one who is still soliciting work despite a revoked license or outstanding judgments — you can report them to several agencies. Your state licensing board takes reports of unlicensed contracting and contractor fraud seriously, particularly because they have enforcement authority.

Your state Attorney General’s consumer protection division handles contractor scam reports and often maintains a public database of actions taken. The BBB accepts new complaints, which become part of the public record. Your county prosecutor’s office handles cases involving criminal fraud — particularly when large dollar amounts are involved or when there’s evidence of intentional misrepresentation.

Reporting matters even if it doesn’t help you directly. A complaint filed today may be the fourth complaint in a pattern that triggers a state investigation and prevents the next homeowner from losing their savings. The homeowner community protects itself — that means contributing to the record when you find something real.

What’s the best overall framework for evaluating a contractor’s risk profile?

Think in terms of categories: license status, business stability, financial conduct, and complaint pattern. A contractor who is strong on all four categories — active license, established business, no court judgments or liens, minimal complaint history — carries low risk. A contractor who has problems in two or more categories carries meaningfully higher risk, and the combination matters more than any single finding alone.

The research sequence in this guide is designed to populate each of those categories with real data. When all seven sources return clean results, you can proceed with confidence. When they return a mixed picture, you have specific questions to ask before you sign a contract. When they return serious findings, you have the information you need to protect yourself — and the next homeowner who might otherwise hire the same contractor.

This is the core of the guide we built at The Complete Guide to Hiring a Contractor: How to Protect Your Home and Your Money — every step in the hiring process, from initial research to final payment.

Frequently Asked Questions

How long does it take to research a contractor online?

A basic contractor research sequence — covering Google, BBB, state license board, and a quick court records check — takes about 20 to 30 minutes. If you extend the search to include county permit records, Secretary of State filings, and social media, you’re looking at closer to 45 minutes for a thorough review. The Echelon Homeowner Contractor Intel Report condenses this entire sequence into a single report you can read in minutes.

What is the most important source to check when vetting a contractor online?

Your state’s contractor licensing board is the single most important source. It confirms the license is active, shows the correct legal business name, and often lists past disciplinary actions — information that no review site can match. License verification takes less than five minutes and should always be your first real stop after a basic Google search.

Can I find out if a contractor has been sued?

Yes. County court records — available free through most state court websites — list civil lawsuits filed against individuals and businesses. Search under both the contractor’s personal name and all known business names. Most state court systems have a searchable online portal that requires no registration and no fee. Look for case types involving homeowners, fraud, abandonment, or failure to pay subcontractors.

What does a Secretary of State search tell me about a contractor?

A Secretary of State business lookup reveals the official registered name, any DBA (doing business as) names, the date the company was formed, its current active or inactive status, and the registered agent of record. A very young company or a recently revived inactive one deserves extra scrutiny. Searching the contractor’s personal name also surfaces any prior business entities they have been associated with.

What should I do if I find red flags in my contractor research?

Don’t ignore the flag and don’t panic. Research the specific issue — a single old complaint is very different from a pattern of lawsuits. If the findings are isolated and old, bring them up directly with the contractor and evaluate their response.

If the findings are serious — revoked license, active court judgments, insurance lapses, or a pattern of business name changes after accumulating complaints — move on to the next contractor. Your home and your money are worth the extra time.
