    Very friendly and great attention to detail. The job took much longer than expected. We could have been kept better informed about the issues that were causing the delays. The crew worked late into the night to get our boiler working before the cold nights came.

    A quick response from Superior Plumbing and Heating in St. Catharines. The service by Brian was professional and courteous but he did not discover the problem and tried to upsell me. Another plumber the next day found a cracked cup in the drain and replaced it. No more leaks.

    Called at 930am. Plumber shows up at 1030am. honest + amazing + affordable. Person handling the phone deserve much praises too on picking up the phone within 2 rings, and manage to take down details quickly and assign the work order fast. Alvin ( sorry if I didn’t spell it right ), was great. came to my place, saw the issue, solved it without any hiccups.

    Commercial plumbing systems maintenance in St. Catharines

    When it comes to your commercial plumbing needs, it’s prudent to be proactive. You already have enough on your to-do list without adding emergency repairs to the mix.

    Most plumbing problems in commercial facilities are caused by wear and tear. Your pipes, systems, and fixtures are built to last, but constant use by employees and customers causes them to fail over time. Regular maintenance from Superior Plumbing & Heating can help you avoid costly repairs or replacements. Our industrial plumber will keep an eye on the condition of your plumbing and take immediate action if any problems arise.

    The most common commercial plumbing problems we encounter are:

    • Clogged sewers and toilets;
    • Silent and active leaks;
    • Leaking faucets and fixtures;
    • Backflow issues;
    • Water heater malfunctions.

    Most of your employees and customers will never see the pipes in your building, but they will use the restrooms. We at Superior Plumbing & Heating strive to keep your restrooms clean and odour-free by providing comprehensive plumbing maintenance services for sinks, drains, and toilets. As the most dedicated commercial plumbing company in St. Catharines, we will help you quickly and efficiently eliminate any odours, sewage clogs, and plumbing damages.
