As a general rule, you can expect plumbers to guarantee their work. But it’s important to understand what that guarantee really means.

What’s covered by a plumber guarantee?

Plumbers’ guarantees normally cover labor -- only. That means, for example, that if a plumbing company in Texas installs your new dishwasher or soaker tub, they can usually be held responsible for any deficiencies in the workmanship, but not in the product.

What happens if the appliance or fixture itself breaks down? That’s a different story. Equipmentand parts tend to be warrantied by the maker, so you should turn to the manufacturing company if there’s a problem in that area.

How long is the guarantee period?

The standard guarantee offered by plumbers is one year on the labor involved in a new installation. (Boiler installation is often guaranteed for as long as three years.) If repairs are guaranteed, it’s usually for a shorter period – 30 days, for example.

How do you make sure you’re covered?

First of all, check before you hire a plumber that he has up-to-date licensing and insurance in your state.

Then, don’t just take your plumber’s word about that guarantee. Ask him to give you a signed contract or invoice which includes details of the guarantee terms and conditions and spells out all exclusions or limitations.

In addition, if the plumber ordered any products or major supplies for your project, make sure you get a copy of the manufacturer’s warranty.
