When a construction or home improvement job involves installing or repairing water, gas or other pipes, it’s smart to hire a licensed plumbing contractor. His or her expertise can help prevent costly water damage to a home’s structural elements. Building a new home or remodeling an existing one nearly always calls for a plumbing contractor as well.

What Does a Plumbing Contractor Do?

A plumbing contractor handles the installation and repair of water, sewage and natural gas pipes throughout a home, as well as interior and exterior faucets and fixtures. Plumbing contractors are also trained to work with water mains, septic tanks, laundry appliances, water heaters, sump pumps and other plumbing and pipe systems. Because plumbing work is done largely behind walls and beneath floors, some plumbing contractors can repair or replace tile, stonework and other surfaces. Although some plumbing contractors are generalists, others specialize in specific areas: residential emergencies and repairs, remodeling, natural gas lines, sprinkler systems and more.

Questions to ask a prospective plumbing contractor:
