How do I find a good, trustworthy plumber?
By the Drain Guru team · Updated September 27, 2026
Quick answer
Pick a plumber before an emergency: check their license with your state board, ask for proof of liability insurance, read recent reviews for patterns (not just the star rating), and ask how they price common jobs. A good plumber explains the problem, gives written quotes, and doesn't pressure you.
Vetting checklist
- License: look it up on your state or city licensing board website.
- Insurance: ask for a certificate of liability insurance.
- Reviews: read the most recent ones and look for repeated praise or complaints about pricing and cleanup.
- Pricing: ask how they charge for a standard drain clearing and what the trip fee is.
- Warranty: how long is labor guaranteed?
- Availability: do they do emergencies, and at what rate?
