What reviewers think

George, Gabriel, Cedric, Jeremy, and Raphie routinely turn up on time and tackle jobs with skill. Customers praise their ability to diagnose complex issues, explain options clearly, and work efficiently. The team has earned trust for honest recommendations and courteous service across faucet repairs, sump pump installs, and drain work.

One customer flagged a $750 job (originally quoted at $1,500 with optional valve work) for a toy stuck in a toilet when typical cost runs $150-300. The plumber declined a price adjustment after the job proved simpler than expected. Most other reviews focus on transparent pricing and professional conduct.

Every review places this business in the five or four-star range, with technicians consistently showing up on time and solving problems the same day or next morning. Matthew, Aaron, Sean, Brian, Farid, Kurtis, Neil, and others diagnose issues clearly, explain solutions in plain language, and finish jobs neatly without leaving mess. Water heater repair, kitchen repiping, drain clearing, and tap replacement all get the same treatment: prompt scheduling, polite handling, and visible pride in the work. A few customers note the technicians took extra time to answer questions and outline preventive steps rather than rush away.

Amir and TAT Plumbing deliver reliable service across water heater replacement, drain clearing, and general repairs in North York. Most customers praise punctual arrival, clear explanations, and fair prices. Two serious complaints allege unprofessional behavior, incomplete cartridge work, warranty avoidance, and lack of licensing verification; these stand apart from the otherwise consistent positive feedback.
