# Plumbers in Louisville: a hiring guide

Updated November 4, 2026

## Four checks before you hire

1. **Confirm the license.** Look the business up with the state licensing board and match the name and number to the quote.
2. **Read recent reviews.** A high rating means more when it rests on many reviews from the last year.
3. **Get at least three written quotes.** Compare what each includes, not only the total.
4. **Ask about warranty and permits.** Find out who pulls the permit and what the warranty covers, in writing.
