If a connection I installed fails weeks later, is that covered?

Generally yes, if the resulting damage extends beyond the fixture or connection itself — this delayed-failure pattern is exactly what completed operations coverage within your GL policy is built to address.

Do homeowners actually ask for proof of insurance for small jobs like a faucet swap?

Increasingly yes, especially for anything touching the main water line or gas line — it's become a meaningful trust signal even for smaller residential jobs.

What's the most common insurance claim for residential plumbers?

Water damage that shows up after the job is done — a connection failing behind a wall or under a slab, discovered days or weeks later — comes up more often than almost any other claim type in this trade.

Does a sewer backup into a finished basement count as a covered claim?

If it's tied to your work — a repair or installation that caused or failed to prevent the backup — that's typically the kind of property damage claim GL is built to cover.

Can one policy cover both my everyday service calls and occasional gas line work?

Yes — one GL policy typically covers your full scope of residential work; just make sure your carrier knows gas line work is part of your mix so it's rated accurately.

Residential Plumber Insurance

The Claim That Shows Up Weeks After You've Left

Residential plumbing has a specific pattern that trips up a lot of operators: the job looks fine when you leave, and the actual claim surfaces days or weeks later when a connection finally lets go behind a wall, under a slab, or above a ceiling. By the time anyone notices, the water damage often extends far beyond anything you were paid to fix — and that's exactly the scenario general liability with completed operations coverage is built to respond to.

Why Homeowners Trust the COI More Than the Handshake

More homeowners are asking for proof of insurance before hiring, especially for water heater installs, repipes, or anything touching the main line. It's become a basic trust signal in a trade where the visible work often looks identical whether it's done right or not — the failure only shows up later.

Working Around Water Heaters, Sewer Lines, and Occupied Homes

Residential plumbing means working around finished floors, cabinetry, and a family's daily routine, often with the main water supply temporarily shut off. A dropped tool, a damaged floor during a fixture swap, or a sewer line issue that backs up into a finished basement are all ordinary parts of the job that general liability is priced to absorb when something crosses from "the job" into "someone else's property."

What Homeowners and HOAs Increasingly Ask For

A growing share of residential plumbing work runs through HOAs and property management companies, which typically want a certificate on file before you touch a single unit in the community — often naming the management company as additional insured.
