Plumbing work puts you inside someone else’s home or business, working around water, gas lines, and systems that can cause real damage if something goes wrong. A single burst pipe you missed or a gas line issue can turn into a costly claim fast. Here’s the coverage a South Dakota plumbing contractor should have in place.
General Liability Insurance
This is the foundation of a plumbing contractor’s policy. It covers injuries and property damage tied to your work, like a flooded basement after a repair goes wrong or a customer tripping over your equipment. Most general contractors and property managers require proof of it before you can start a job.
Check our general liability coverage page for typical limits and what’s included.
Commercial Auto Insurance
Service vans, work trucks, and trailers hauling pipe and fittings all need coverage built for business use. Your personal auto policy won’t cover an accident that happens on a service call. Commercial auto protects your fleet on the road and covers you if a driver causes a crash while working.
See our commercial auto insurance page for coverage options built around work vehicles.
Contractor Insurance for Tools and Equipment
Pipe threaders, drain machines, and specialty tools represent a real investment, and a lot of that equipment travels between job sites or sits in a van overnight. Our contractor insurance page covers protection for tools and equipment on the move, which standard property insurance often doesn’t reach.
Workers’ Compensation
Plumbing is physical work that involves tight spaces, heavy lifting, and power tools. If a crew member gets hurt, workers’ comp covers medical bills and lost wages, and it protects your business from most related lawsuits. Details on our workers’ compensation page.
Commercial Umbrella Insurance
Water damage claims can get expensive quickly, especially if a repair causes damage to multiple floors or units. Umbrella insurance adds a layer of protection above your general liability and auto limits, so one serious claim doesn’t put the whole business at risk.
Read our commercial umbrella insurance page for how it works.
Why Clients Ask for Proof of Insurance
Property managers, general contractors, and homeowners increasingly ask for a certificate of insurance before letting a plumber start work, especially on larger commercial or remodeling jobs. Carrying the right coverage, and being able to prove it quickly, can be the difference between winning a bid and losing it to a competitor.
Bundling Coverage
Many plumbing contractors combine general liability and property protection into a Business Owners Policy to simplify billing and often reduce cost. Our business owners insurance page explains how that bundling works.
