About This Market
Caldwell's plumbing market serves a growing residential base plus agricultural irrigation systems unique to the Treasure Valley.

You need that Idaho plumber license - no shortcuts, and the state actually enforces it. City permit process is straightforward but required for anything beyond basic repairs. Winter is your money season with freeze-ups and heating system issues. Agricultural clients pay well but expect fast response during irrigation season.
