About This Market

UPDATED APR 2026

Lewiston's plumbing market runs steady year-round with 825 licensed establishments statewide competing for work. Winter freeze-ups drive emergency calls while summer brings remodel season. Median wage hits $28.42/hour reflecting decent demand in this blue-collar town. Costs stay reasonable compared to Boise - materials transport from Spokane keeps overhead manageable.

Local inspectors know their stuff and won't pass shoddy work. Winter emergency calls pay premium rates but you'll earn every dollar crawling under frozen houses. Lewiston contractors who build relationships with local supply houses and respond fast to service calls stay busy. Skip the fancy marketing - word of mouth and reliable service win jobs here.
