Reviewed October 1, 2026 · Wyoming plumbing contractors
Wyoming has no statewide plumber license, so insurance minimums are set by each city. Casper, for example, requires $250,000/$500,000 personal injury and $250,000 property damage for plumbing contractors. Workers’ comp runs through the state. Here’s what to have ready before you ask for quotes.

Wyoming plumbing insurance requirements
What Wyoming requires for plumbing businesses
Casper requires plumbing contractors to carry at least $250,000 per person and $500,000 per incident for personal injury or death, and $250,000 property damage per incident. Other cities set their own minimums.
A licensing minimum is a floor, not a recommendation. Customers, general contractors and property managers often ask for higher limits, so get their requirements in writing.
Workers’ comp
Wyoming workers’ comp is handled by the state: businesses in extra-hazardous industries must have coverage through the Department of Workforce Services before work begins, based on their business activity. Optional businesses can choose coverage (Wyoming DWS).
Local rules
Cities and counties can add their own requirements. Before you register locally or pull a permit, ask the building department whether it wants a certificate of insurance, a bond or workers’ comp proof on file.

Which policies should a Wyoming plumber compare?
| Risk | What to ask about |
|---|---|
| A leak, flood or sewer backup damages a customer’s property, during or after a job | General liability that meets any license or contract limits, including products and completed operations. Ask how it handles water damage, mold, work in occupied homes and any exclusions for the kind of work you do. |
| An employee gets hurt | Workers’ comp under Wyoming’s rules. Give accurate payroll and job duties, and explain how you use subcontractors. |
| Your van or truck | Commercial auto for business use, the vehicles and everyone who drives them. General liability doesn’t cover your vehicle, and a personal auto policy may not cover a work van. |
| Tools, drain cameras, jetters and equipment | Tools and equipment (inland marine) coverage. Ask about theft from a vehicle, tools left on site overnight, rented equipment and deductibles. |
| A shop, stock or bigger contracts | Property coverage or a business owner’s policy, plus umbrella coverage if a contract asks for higher limits. |
Describe the work you actually do
Tell the insurer whether you do service and repair calls, drain cleaning, sewer line work, excavation or trenching, gas piping, water heaters, backflow testing, new construction or commercial work. Mention subcontractors and any work in occupied buildings. A quote built on a narrower description, such as “handyman,” may not cover the jobs you take.
Ask what happens when your own work fails. Liability insurance isn’t a warranty. Fixing a bad joint and paying for the water damage it caused are often treated differently. Ask the agent to walk you through it.
Already insured and need a certificate?
Start with your current agent or insurer. Ask each city license office (for example, Casper or Cheyenne) what certificate it wants. For a customer, send their written insurance requirements, the project address and how they want the certificate holder listed.
A certificate only shows what your policy already covers. It doesn’t change the policy. Being listed as certificate holder is not the same as being an additional insured, so if a contract asks for additional insured status, a waiver of subrogation or primary wording, ask whether you need an endorsement. Put renewal dates on your calendar so required coverage never lapses.
How much does plumbing insurance cost in Wyoming?
There isn’t one Wyoming price. Your quote depends on the work you do, revenue, payroll, subcontractors, claims history, vehicles, equipment, limits and deductibles. We don’t have a reliable Wyoming average to share, and we won’t guess at one or promise a Simply Business price.
- Compare quotes with the same work description, limits, deductibles and policy dates.
- Ask for the full yearly cost, plus any installment or endorsement fees.
- Price workers’ comp and auto separately from general liability.
- If a quote is a business owner’s policy, check what it bundles so you don’t count coverage twice.
- Ask whether a payroll or revenue audit could change the final bill.
A cheap policy that excludes work you do is the wrong policy. Have the agent explain the differences before you choose on price.
Get your Wyoming insurance quote ready
- Your legal business name, address, city plumbing contractor license numbers, start date and experience.
- The services you offer, your residential and commercial mix, typical job sizes and the area you cover.
- Revenue, payroll, what each worker does, owners and subcontractors.
- Vehicles, drivers, tools, equipment values and where they’re kept overnight.
- Past claims, current policies and their end dates.
- The certificate rules from each licensing office you deal with, and each customer’s written insurance requirements.
Before you take a job, ask the insurer to confirm in writing which work is covered, the exclusions, the limits and the start date. Asking for a quote doesn’t give you coverage. Simply Business offers insurance for plumbers, but whether a policy fits still depends on your business and the insurer.

Common Wyoming plumbing insurance questions
Does Wyoming require liability insurance or a bond for plumbing businesses?
There’s no statewide plumbing insurance minimum. Casper requires plumbing contractors to carry at least $250,000 per person and $500,000 per incident for personal injury or death, and $250,000 property damage per incident. Other cities set their own minimums.
When do I need workers’ comp in Wyoming?
Businesses in extra-hazardous industries must have coverage through the Department of Workforce Services before work begins, based on their business activity. Optional businesses can choose coverage.
Does general liability cover my van or a hurt employee?
Usually not. Those normally need commercial auto and workers’ comp. Read the actual policies rather than assuming a plumbing package covers everything.
Does forming an LLC replace insurance?
No. An LLC, your license and your insurance each do a different job. Our Wyoming LLC guide covers formation.
Is the minimum enough for a commercial job?
Not always. General contractors and commercial customers often ask for higher limits and extra endorsements. Read the contract before you bid and ask your agent about any gaps.
