    I had an excellent experience with superior plumbing and heating when George installed a new sump pump in my home. From start to finish, they were punctual, professional, and clearly knew their trade. The work was done quickly and cleanly, and they took the time to explain how everything works and what to watch for in the future. It’s rare to find a plumber who takes such pride in their work and treats your home with respect. I feel confident and at ease knowing my basement is protected thanks to a job well done. Highly recommend to anyone needing reliable plumbing services!

    Why is it important to check the building’s drainage system?

    Drain lines should only be checked when there is concern about slow draining, clogging or other problems. But an inspection can catch problems before they become serious. Businesses can save time and money by having their drainage systems inspected.

    You can protect your drainage system by scheduling a drain pipe inspection. Superior Plumbing & Heating uses high-resolution CCTV cameras, controlled remotely, to inspect the drainage system. This allows our commercial plumber in St. Thomas to get an accurate picture of the pipes and their structural integrity (clogs, cracks, etc.) and even identify potential future problems. Of course, this can be done on the same day or at a time that suits you.
