Plumbing is a water-damage business as much as a pipe business. A failed connection, a frozen line, or a fitting that lets go after the job can flood a finished space and turn into a six-figure claim months later. We build your program around the exposures that actually drive plumbing claims, water damage, freeze events, and the long completed-operations tail, and place it with carriers that price plumbing for what it is.

A plumbing contractor typically needs general liability, workers' compensation, commercial auto, and tools & equipment coverage, with umbrella/excess limits for larger commercial work. Plumbing's defining exposure is water damage, a connection or fitting that fails after the job is completed, so occurrence-form general liability with intact completed-operations coverage is the most important part of the program.
Each line below is a separate policy with its own pillar. We build them into one program, one quote, one renewal, one broker, so the gaps between them close. Every placement is subject to carrier underwriting.
The policy GCs, property managers, and homeowners require before you start, and the one that matters most for plumbing. A connection that fails and floods a finished space, sometimes long after the job, is the signature plumbing claim, and completed-operations coverage on an occurrence form is what responds. We confirm your form carries that tail intact.
Required once you have W-2 employees. Plumbing loss drivers are burns from torches and hot work, cuts, lifting and back injuries, trench and confined-space hazards, and falls. Coding your operation correctly at bind protects both your rate and a clean audit.
Service vans and work trucks carrying tools, fixtures, and materials are a working fleet, not a personal vehicle. Hired & non-owned auto covers techs running for parts in their own cars, a common and easily-missed gap.
Commercial plumbing contracts frequently require $5M+ in combined limits. A water-damage claim in a multi-unit building or commercial space can climb past a primary limit quickly, so umbrella is both a contract requirement and meaningful protection.
These are the exposures carriers underwrite for your trade. Understanding them is how you avoid the “I thought that was covered” call, and how we match you to a market that prices the work fairly.
A joint, supply line, or fitting that lets go, immediately or months later, can flood a finished space, a unit below, or an entire commercial floor. Water damage is the single most frequent and most expensive plumbing exposure, and completed-operations coverage is what responds when it surfaces after the job.
A line that freezes and bursts because of how it was run, insulated, or left can cause catastrophic water damage. Freeze claims are seasonal and severe, and how the work was performed often determines whether the loss is yours.
Plumbing has one of the longer completed-operations tails of any trade, a failure that surfaces a year or two after completion is still your liability. Occurrence-form GL with intact completed-operations is what keeps that long tail covered.
Soldering and torch work introduce ignition risk inside walls and finished spaces. A fire started by hot work is a severe GL claim, and some carriers ask about hot-work practices specifically when underwriting plumbing.
Sewer, water-main, and underground work expose crews to trench collapse, confined-space hazards, and utility strikes. These are severe workers' comp and liability exposures, and documented safety practice is what carriers reward.
Many jurisdictions require a licensed master plumber (an RMP or equivalent) and set minimum insurance limits to hold or renew the license. Carrying the right limits is not only a contract question but a licensing one, and we match your coverage to both.
| Factor | Impact | Detail |
|---|---|---|
| Residential vs. commercial mix | Major | Residential service, commercial new construction, and underground/sewer work each carry different class codes and exposure. Your split across them is a primary driver of price. |
| Annual payroll & revenue | Major | Workers' comp is rated per $100 of payroll and GL on gross receipts. Volume and how it splits across work types drives the premium. |
| Underground / excavation work | Major | Sewer, water-main, and trench work add severe injury and utility-strike exposure that some markets surcharge. Disclosing it accurately changes appetite and price. |
| Licensing & experience | Moderate | A licensed master plumber (RMP or equivalent) and documented clean experience earn standard-market access and can satisfy state license-bond and limit requirements. |
| Claims history | Moderate | Water-damage and freeze claims are frequent and add up. A clean five-year loss run keeps you in preferred markets. |
| Subcontracted labor | Moderate | Uninsured 1099 help shifts exposure onto your policy and shows up as additional premium at audit on both GL and WC. |
| State | Minor | Licensing regimes, freeze climate, and litigation vary. States like Texas (which sets RMP licensing and limit rules), Pennsylvania, and Florida each price to their own climate. |

A connection made up on a commercial restroom riser let go over a weekend, sending water through three floors of finished office space before anyone noticed. Drywall, flooring, and tenant equipment were ruined.
General liability responded to the third-party water damage, and because the contractor carried a $5M umbrella, there was capacity well above the GL limit. Risk transfer worked as the commercial contract intended.
A water line run through an exterior wall on a finished basement froze and burst in the first hard winter, flooding the renovated space and ruining roughly $48,000 of new drywall, flooring, and built-ins. The homeowner pursued the plumber over how the line had been routed and insulated.
Because the failure traced back to finished work, the occurrence-form GL in force when the repipe was done answered the third-party water damage, even though the job had wrapped a full season earlier and the policy had since renewed. A freeze that does not surface until January is a textbook reason plumbing GL has to carry its completed-operations tail intact.
A solder joint near old framing ignited concealed material during a repipe, and the fire spread inside the wall cavity before it was caught. Smoke and fire damage to the home followed.
General liability covered the fire damage and the related claim. The contractor adopted a written hot-work checklist with a fire-watch step, which the carrier noted favorably at renewal.
An unshored trench on a sewer-line replacement partially collapsed, pinning a laborer's leg before the crew dug him out. Fractures and several weeks off the job followed.
Workers' comp paid the full medical course and replaced lost wages. The carrier's safety consultant helped the contractor formalize a trench-protection and shoring protocol, which contained the experience-mod impact.

Most plumbing contractors need general liability and (once they have employees) workers' compensation, plus commercial auto for service vans and tools & equipment coverage for gear. Larger commercial plumbers typically add umbrella/excess liability. Because water damage is the defining plumbing exposure, occurrence-form GL with intact completed-operations coverage is the most important piece. The right program depends on your work mix and is subject to underwriting.
Third-party water damage from your defective plumbing work is typically a general liability claim, and on an occurrence form with completed-operations coverage it can respond even when the leak surfaces months or years after the job. The cost to re-do the defective work itself is generally a workmanship issue, not a GL claim. Because water damage is so central to plumbing, we confirm your form carries the completed-operations tail intact.
A third-party damage claim from a line that froze and burst because of how it was run or insulated is typically handled like any other completed-operations water-damage claim under occurrence-form GL. Freeze losses are seasonal and severe, and how the work was performed often determines whether the loss is yours. We review your form so you know where coverage applies before the first hard winter.
Licensing and minimum-limit rules vary by state, many jurisdictions require a licensed master plumber (an RMP or equivalent) and set minimum insurance limits to hold or renew the license. Carrying the right limits can be both a contract and a licensing requirement. Tell us your state and license status and we will match your coverage to the limits you actually need to carry.
No. General liability covers damage you do to other people's property, not loss of your own gear. A stolen drain machine, a sewer camera dropped down a line, or jetting equipment taken off a truck overnight falls under tools & equipment (inland marine) coverage, not GL. Because a sidelined camera or jetter can stall a job for days, we typically place this coverage alongside the liability lines so a single theft does not put you off the schedule.
Once your policy is bound and the certificate holder details are available, we typically issue COIs in under 60 seconds. If a GC, property manager, or homeowner needs proof of coverage before you can start, that turnaround usually is not the bottleneck.
It varies by your residential/commercial/underground work mix, your payroll and revenue, how much excavation you take on, and your loss history, water-damage and freeze claims weigh heavily. State licensing rules can also set minimum limits you must carry. Because work mix moves both class code and which carrier fits, a single quoted number is misleading; we shop your specific operation across multiple carriers and show you real options. Getting the quote is free.
Often, yes. Sewer, water-main, and trench work add severe injury and utility-strike exposure that some markets surcharge or underwrite specifically. If you do excavation work, disclosing it accurately changes both appetite and price, and ensures the exposure is actually written into the policy rather than discovered at claim time. We map that work before shopping the markets.
