Best Plumbers in Baltimore, MD

Confirm the plumber holds a current state license (master or journeyman depending on the job) and carries active liability insurance — request a current certificate before work starts. Compare at least two or three Google-rated plumbers in your city before calling, and ask for a written estimate before any work begins.

A diagnostic visit or service call runs $75–$150. Drain clearing costs $100–$350; toilet replacement $250–$550 installed; water heater replacement $900–$1,800 (tank) or $1,500–$3,500 (tankless). Sewer camera inspection is $150–$400.

Simple repairs (leaky faucet, running toilet) take 1–2 hours. Water heater replacement is a half-day job. Sewer line repair or full repiping can take 1–5 days depending on scope.

Ask for their license number and tier (master vs. journeyman), proof of general liability insurance, whether they pull permits for the job, and what their hourly rate is versus a flat project price. Get everything in writing before they start.

Listings are sourced from Google Business Profiles and ordered by real Google ratings and review volume. We display each plumber's star rating and total review count so you can make an informed comparison. Independently confirm licensing with your state board before hiring.

Contact the plumber in writing and request they return to address the issue. If work was licensed, you can file a complaint with your state plumbing licensing board. For billing disputes, dispute the charge with your credit card company and document everything with photos and written records.
