Washington plumbing FAQ

How do I check a plumber's license in Washington?

The Washington State Department of Labor & Industries (L&I) certifies plumbers and registers contractors.

Do pipes freeze in Washington?

Yes, during cold snaps. Pipes in crawl spaces, exterior walls and unheated garages are the ones that freeze. Disconnect hoses in fall and open sink cabinets on the coldest nights.

Is Washington water hard?

Generally soft, based on national hardness mapping, but it varies by utility and by well. Your water provider's annual water quality report lists the hardness for your system, and a plumber can test well water.

How old are homes in Washington?
