Is workers comp really priced differently for plumbers than other trades?

Confined-space entry and back-strain injuries specifically are a significant driver of plumbing-trade workers comp claims, which carriers factor into how they rate a plumbing crew versus a less physically demanding occupation at the same payroll.

Do I need to insure my sewer camera and jetter separately from other tools?

They typically fall under the same tools and equipment coverage, but make sure your policy's total insured value reflects the real replacement cost of this specialized gear — it adds up fast and is easy to underinsure.

How does using subcontractors for excavation or gas hookup affect my insurance?

You still need a current certificate of insurance from every subcontractor you bring on, regardless of the specific scope, to protect your own policy if a claim arises from their work.

At what crew size does my GL rating change significantly?

There's no single threshold — it's a gradual shift based on payroll and total job volume across your crew, not a specific headcount cutoff.

Do larger commercial and municipal contracts require higher limits than residential jobs?

Often yes — $2M/$4M is common for larger commercial and municipal contracts, compared to the $1M/$2M that satisfies most residential work. We can quote both.

Plumbing Contractor Insurance

More Crews Means More Places Something Can Go Wrong at Once

A solo plumber has one truck, one job site, one set of connections to worry about on any given day. Add a crew and you're suddenly carrying that same failure risk multiplied across every site your people are touching simultaneously — which is exactly why carriers rate a plumbing contractor's exposure on more than just total payroll.

The Physical Toll of This Work Shows Up in Your Workers' Comp Rate

Crawlspaces, trench work for sewer repairs, and cramped mechanical rooms are just part of the job in this trade, and that confined-space reality drives real injury exposure — back strain, awkward-position injuries, occasional torch burns. The day you bring on your first W-2 employee, workers' comp becomes mandatory in most states, and carriers price this class with that physical toll already factored in rather than treating it like office work. Our cost comparison walks through real numbers at each crew size.

Your Equipment List Looks Nothing Like a Generic Contractor's

Sewer cameras, jetters, press tools, pipe threaders — sometimes excavation equipment if sewer line work is part of your scope. This gear is specialized and expensive, and a crew-level tools and equipment policy needs a limit that reflects what you're actually running, not a generic contractor estimate.

Bigger Jobs Mean More Subs, and More Paperwork to Chase

Once jobs get large enough to need excavation crews or gas line specialists you don't employ directly, subcontractor documentation becomes part of protecting your own policy. A current certificate of insurance from every sub you bring on is the paperwork habit that saves you if a claim ever traces back to their portion of the work.

What Growing Actually Changes About Your Policy

Bigger crews, more equipment value, larger contracts — all three should be reflected at your next renewal, not just whenever a claim forces the conversation. Higher limits, standard additional insured and waiver of subrogation language, and workers' comp sized to your actual headcount are all part of that. See our cost breakdown for how these factors move the number.
