Red Flags & Scams

7 Red Flags of a Sketchy Contractor (And How to Walk Away)

Most Minnesota contractors are honest and hardworking. This guide is about the other kind—the ones who dodge questions, rush you into paying, and leave you stressed and second-guessing. Here are seven warning signs to watch for before you sign anything.

Hiring a contractor shouldn’t feel like gambling with your house. But once a bad one is on your property, it’s hard and expensive to undo the damage.

The good news: shady contractors are not as sneaky as they think. They leave clues. The seven red flags below are simple things you can spot early, before you sign or pay a big deposit—no matter what trade they’re in.

If you see one of these, slow down. If you see two or more, it’s probably time to thank them for their time and move on.

Big picture: how a contractor handles basic questions about licenses, insurance, and the contract is a preview of how they’ll act if something goes wrong on your job. If they’re annoyed now, they won’t magically become easier to deal with later.
1

They can’t or won’t prove insurance and licensing

In Minnesota, legit contractors expect you to ask about licenses and insurance. They usually have that information ready and can email or text it to you in a couple of minutes.

Red flag behavior looks like this: changing the subject, saying “we’re covered, don’t worry about it,” or only showing you a blurry screenshot on their phone that you can’t verify.

If someone gets weird about simple proof, it usually means the paperwork is expired, not in their name, or doesn’t exist at all. That puts all the risk on you if there’s an accident or damage to your property.

MNCC TIP Ask for their license number and a certificate of insurance that lists their business name. Then verify it through state websites and the insurance agent—not just screenshots.

The price is crazy low and nothing is written out

It’s normal for quotes to be different. One contractor might be a little higher because they include more cleanup, better materials, or a longer warranty. That’s fine.

The problem is when one quote is way lower than everyone else, and the paperwork is nothing more than “we’ll take care of it” or a one-line text with a dollar amount. That usually means corners will be cut, surprise charges are coming, or the job won’t be finished the way you expected.

If you can’t tell exactly what you’re paying for, you have no way to hold them to anything when the work doesn’t match what you had in your head.

MNCC TIP Only move forward with a quote that clearly lists what’s included, what’s not, and how extra work is billed. If they refuse to write it down, that’s your signal to walk away.

They push for a big cash deposit right now

Deposits themselves aren’t the problem. Many honest contractors need money up front for materials or to hold your spot on the schedule.

The red flag is the combination of high pressure + big money + no paperwork. Examples: “I can give you a deal but only if you pay cash today,” or “I need half down in cash before I can even order materials,” with nothing formal in writing.

Once that money leaves your hand without a clear contract, you’ve lost almost all leverage. If they disappear or stall, getting that cash back is extremely difficult.

MNCC TIP Never hand over a large deposit without a written contract that includes scope, total price, and a payment schedule tied to milestones. Use a payment method you can document, not an envelope of cash.
4

You can’t find a real business behind the person

Everyone starts small. There’s nothing wrong with a one-truck operation or a newer company. The issue is when there is no sign of a real business at all.

Warning signs: the name on the estimate doesn’t match the name on the truck, the business name changes from text to text, you can’t find them in Minnesota’s business search, and there’s no consistent name on their website, social media, or paperwork.

If something goes wrong, you need to know exactly who is responsible—not just “some guy with a tool bag and a pickup.”

MNCC TIP Make sure the business name matches across their contract, invoice, website, license, and insurance. If you’re seeing three different names, stop and ask why before you sign.
5

They have no reviews, no references, and no real photos

Not every good contractor has a huge online presence, especially in smaller towns. But there should be something—a couple of Google reviews, a Facebook page, or photos from recent jobs that actually look like their work.

Be careful if all you see are stock photos, stolen-looking pictures, or vague excuses like “our customers don’t like to leave reviews” and “we don’t really do online stuff.” That can be a sign they just don’t want a public trail that ties back to them.

You don’t need a Hollywood portfolio, but you do deserve proof that they’ve successfully done your type of project before.

MNCC TIP Ask for two recent projects similar to yours and, if possible, a quick way to confirm them (photos, addresses, or a past client willing to talk). If they can’t provide that, you’re taking a big leap of faith.
6

Communication is messy before the job even starts

However they treat you before you sign is usually the best they’ll ever treat you. If they’re late to the estimate, forget what you already talked about, or constantly “lose” your messages, that pattern won’t magically fix itself mid-project.

You don’t need a contractor who writes perfect emails. But you do need one who confirms dates, times, prices, and changes in writing so there’s no confusion later.

If you already feel like you’re chasing them down just to get simple answers, imagine what it will be like if there’s a problem with the work.

MNCC TIP Notice whether they summarize things in writing after you talk—a quick text or email with the plan, price, and date. If everything lives in vague phone calls, you have nothing to point back to if stories change.
7

They get defensive when you try to double-check them

This is a huge one. Good contractors usually respect careful homeowners. Many of them are homeowners themselves and know how it feels to invite someone onto their property.

Pay attention to their reaction when you say things like “I’m going to verify your license,” “I’d like to call your insurance agent,” or “I’m going to get one more quote before deciding.”

If they stay calm and supportive, that’s a green flag. If they roll their eyes, get angry, or try to guilt you for “not trusting them,” that’s a preview of how they’ll handle any disagreement.

MNCC TIP You’re not being rude by checking licenses, insurance, reviews, or business standing. You’re protecting your home and your money. Any contractor who respects you as a client will respect that process too.
