Need a Registered Licensed Plumber or Gasfitter?

Customers must use a licensed journeyman or Master Level plumber who is individually registered or works with a registered firm. Request proof of registration of their license.

Note: Valid license/registration numbers (three to five numbers; for example, WSSC-12345) must be printed on all of their paperwork and vehicle.

How Many Price Quotes Should I Get?

Whether you need simple repairs or contracted projects, it is recommended to seek three to five price quotes for all planned work. But remember, you must use a WSSC Water-licensed and -registered plumber or gasfitter.

Small Repairs and Direct Fixture Replacement?
