Achievements of Superior Plumbing

I specifically asked for Mike again because he’s so thorough. He handled our commercial plumbing service with the same care as our residential repairs. He found a secondary leak in the mechanical room we weren’t even aware of. A technician you can actually trust.

Had an urgent commercial plumbing situation at 11 pm in St. Catharines. Aaron arrived within 45 minutes and resolved the sewage backup. He didn’t have the right industrial gasket on hand but made a temporary fix and was back first thing in the morning to finish it properly. Great emergency service.

Superior Plumbing did excellent commercial work at our property. Steve clearly has years of experience—his precision with the high-rise piping was top-notch. The quote was fair and the work was finished ahead of schedule. Top quality trade work.

Third time using Superior in St. Catharines for our commercial rentals. Kevin was knowledgeable and very professional. The quote was fair and the results are perfect. Consistency is why I return to them for every building I manage.
