Every policy explained in plain English: what it covers, who needs it, what it costs, and the mistakes that trip contractors up.

Insurance is one of those things that feels like a waste of money, right up until the moment you need it. And then it's the only thing standing between you and financial ruin.
The problem is, most contractors don't really understand what they have, what they need, or what they're paying for. Your insurance agent rattled off a bunch of policy types, you nodded, picked the cheapest option, and moved on with your day. Now you've got a binder in your filing cabinet that you've never opened and a monthly bill you resent.
Let's fix that. Here's what each type of contractor insurance actually covers, who needs it, what it roughly costs, and the mistakes that trip people up.

General liability is your baseline. It covers you when your work causes damage to someone else's property, when someone gets injured on your job site, or when you get sued for something related to your business operations.
Some real-world examples:
Every contractor. Period. This is non-negotiable. If you're doing work on someone else's property, you need general liability insurance.
Most states don't technically require GL insurance (workers comp is the one states mandate), but practically speaking, you can't operate without it. No GC will sub you without seeing your GL certificate. No serious homeowner should hire you without it. And if something goes wrong on a job without GL coverage, you're personally liable for every dollar.
$500 to $3,000 per year for most small contracting businesses, depending on your trade, revenue, and claims history. Higher-risk trades like roofing and demolition pay more. Lower-risk trades like painting and flooring pay less.
Workers comp covers your employees when they get injured on the job. It pays their medical bills, replaces a portion of their lost wages while they recover, and covers rehabilitation costs. It also provides death benefits to families if the worst happens.
Just as importantly, it protects you. In most states, workers comp is the "exclusive remedy", meaning your employees can't sue you for workplace injuries if you carry coverage. Without it, they can sue you personally for everything.
If you have employees, you almost certainly need workers comp. The requirements vary by state, some kick in with the first employee, others start at three or five. A handful of states exempt sole proprietors with no employees, but even then, many GCs require proof of coverage before they'll work with you.
The 1099 question comes up constantly. Just calling your crew "independent contractors" doesn't get you off the hook. If they walk, talk, and work like employees, your state's labor board will likely classify them as employees, and you'll owe back premiums, penalties, and liability for any injuries.
Workers comp premiums are calculated based on your payroll, your trade classification, and your experience modification rate (how your claims history compares to your industry average). For most small contractors, expect $2,000 to $10,000 per year. Roofers and framers pay more per dollar of payroll than electricians and painters because the injury risk is higher.
Your personal auto policy has an exclusion for vehicles used for business purposes. If you're driving to job sites, hauling materials, or using your truck as a mobile office (which every contractor does), you need commercial auto coverage.
Commercial auto covers liability when you or your employees cause an accident in a company vehicle, physical damage to your trucks and trailers, medical costs for injuries, and uninsured/underinsured motorist protection.
Any contractor who uses a vehicle for work. If you're driving your F-250 loaded with tools and materials to a job site, your personal auto policy probably won't cover a claim. And if you have employees driving company vehicles, you need commercial auto, your personal policy definitely won't cover them.
$1,200 to $3,500 per vehicle per year for most contractors, depending on the vehicle type, driving records, coverage limits, and your state. Add trailers and specialized equipment to the policy for a few hundred more.
This one has a confusing name, it has nothing to do with boats. Inland marine insurance covers your tools, equipment, and materials while they're in transit or at a job site. Your general liability policy covers damage you cause to other people's stuff. Inland marine covers damage to your stuff.
Think about everything in your truck and trailer right now: power tools, hand tools, generators, compressors, ladders, specialty equipment. What would it cost to replace all of it tomorrow? For most contractors, the answer is $10,000 to $50,000 or more.
Inland marine covers theft, fire, vandalism, and accidental damage to your tools and equipment, whether they're in your truck, at a job site, or in your shop.
Any contractor with a significant investment in tools and equipment. If losing your tools to theft would shut you down for a week or cost you five figures to replace, you need this coverage.
$500 to $2,000 per year for most small contractors, based on the total value of equipment you're insuring. It's one of the cheapest policies relative to what it protects.
An umbrella policy sits on top of your other policies and kicks in when a claim exceeds the limits of your GL, auto, or workers comp coverage. Think of it as a safety net for the safety net.
If you have a $1 million GL policy and a lawsuit judgment comes in at $1.5 million, your umbrella policy covers the $500,000 difference. Without it, that half-million comes out of your pocket.
Any contractor doing work that could result in large claims, which is most contractors. If you're working on high-value homes, doing structural work, working at heights, or doing anything near utilities, the potential for a seven-figure claim is real.
Umbrella policies are also increasingly required by GCs on larger projects. If the project owner requires $5 million in coverage and your GL only goes to $2 million, an umbrella gets you there.
$500 to $1,500 per year for $1 million in additional coverage. This is genuinely cheap insurance for the protection it provides. Each additional million is typically a few hundred dollars more.
A surety bond isn't insurance, it's a guarantee. When you get bonded, a surety company guarantees to your customer that you'll complete the work as agreed. If you don't, the surety pays the customer and then comes after you for reimbursement.
There are different types:
It depends on your market. If you're doing residential remodeling, you may only need a license bond required by your state. If you're chasing commercial or government work, performance and payment bonds are almost always required.
Being bondable is also a credibility signal. It tells customers that a third-party financial institution has evaluated your business and is willing to stand behind you. That's meaningful to sophisticated buyers.
License bonds: $100 to $500 per year for most contractors. Performance bonds: typically 1% to 3% of the contract value, though this varies widely based on your credit, experience, and the project size.
Now that you know what you need, here's how to actually buy it without overpaying or getting the wrong coverage.
An independent insurance broker represents multiple carriers, which means they can shop your coverage across many companies and find you the best combination of price and coverage. A captive agent (someone who only sells for one company) can only offer you what that company has, which might not be the best fit.
Insurance for contractors is different from insurance for a retail store or an office. Classification codes, experience mods, audit procedures, certificate requirements, there's a lot of industry-specific knowledge involved. An agent who mostly writes homeowners policies isn't going to serve you well.
Ask other contractors who they use. Check with your local trade association. Look for agents who mention construction or contracting on their website.
Most carriers give discounts when you bundle multiple policies. Your GL, workers comp, commercial auto, and inland marine with one carrier (or through one broker) will almost always be cheaper than buying them separately from four different companies.
Your business changes every year. Your revenue, your payroll, your equipment, your risk profile, it all shifts. Review your coverage annually with your agent to make sure you're not underinsured or overpaying.
The cheapest policy is not the best policy. What matters is the coverage, the claims process, and the carrier's financial stability. A carrier that saves you $300/year but takes six months to process a claim and fights you on every dollar isn't saving you anything.
Insurance isn't exciting. Nobody got into contracting because they love talking about policy limits and deductibles. But this stuff is the foundation that lets you take on bigger jobs, work with better clients, and sleep at night knowing one bad day won't destroy everything you've built.
Get the right coverage. Work with a good broker. Build the cost into your pricing. And then go back to doing what you actually enjoy, building things.
