    I’m so pleased with the service we got from Superior Plumbing. They were excellent. I called them about a broken flow valve in the toilet tank and they had Kurtis out the same day to have a look at it. Kurtis was extremely friendly and professional. He had great customer service skills explaining everything he needed to fix and options we had. Kurtis fixed the problem quickly and did a great job. I would definitely recommend Kurtis and this company for any plumbing problems. The only issue I had was with the receptionist-I could hardly hear them and they were extremely difficult to understand. Maybe it was their headset or a bad phone line but it sounded like they were mumbling. Otherwise, everything was great! 😊

    My second time using Superior Plumbing and Heating of Montreal. Again, super happy with the experience. Alvin arrived on time and completed the work in a timely manner. He even had to pop out to the plumbing supply store to get a needed part. Problem fixed with very little effort on my part! Awesome experience. See below for first time review. First time review: Super happy with Superior Plumbing and Heating of Montreal. I called with a tankless heater issue in the morning, they were able to come and assess within hours, and then discussed various solutions. In the end I opted to replace the unit and they were able to do the work same day. Their plumber and install technician were polite, knowledgeable, and skilled at their trade. All options were discussed, they worked hard to ensure I was happy with the end result, and they left the house in the same condition as they found it. So happy to have hot water restored in record time. 10/10 would use again!

    If you’re picky about who works on your home, call this business. I had them out for a fairly complex pipe repair, and I was impressed by their attention to detail they really help to repair the pipes of my house.

    How Much Does It Cost to Fix Plumbing Leaks in St. Catharines?

    As a rule, our plumber can only quote the final price after assessing the pipes’ condition, size, and complexity of the leak. So anyway, we always bring the cost of repairs to the average in the Canadian market to fix plumbing leaks at an affordable price for you in St. Catharines.

    We at Superior Plumbing & Heating have maintained a stable and transparent pricing policy since 2005. Also, the initially approved cost never exceeds the final amount, which makes you feel comfortable working with us.

    Even if unforeseen circumstances arise and a breakdown requires additional parts or work, our experts first agree on additional costs with the client, provide a new estimate, and only then get down to work. Last but not least is our 90-day warranty on all services. Our team fixes the breakdown for free in case of repeated plumbing St. Catharines issues. But since our aces are proficient in flawless repairs, recurring malfunctions never happen to our customers.

    Frequently asked questions about plumbing leaks in St. Catharines

    Can a plumbing leak affect my water pressure?

    Yes, a plumbing leak can significantly affect your water pressure. When there is a leak in your pipes, water escapes from the system, reducing the overall pressure. If the leak is large enough, it may cause a noticeable drop in water flow, making it difficult to use multiple fixtures at once. Additionally, if the leak is in a main pipe, it can lead to a more severe loss of pressure throughout your home. If you notice low water pressure along with signs of a leak, it’s important to have it repaired as soon as possible to avoid further issues. Contact us for a professional inspection and prompt repair!

    How can I tell if a plumbing leak is coming from my water heater?

    To determine if a plumbing leak is coming from your water heater, look for the following signs:

    • Water accumulation. Puddles or moisture around the base of the water heater.
    • Connection issues. Dripping or wet spots near the connections, such as the inlet or outlet pipes.
    • Corrosion or wear. Rust or corrosion on the tank or its components.
    • Performance problems. Reduced hot water supply or inconsistent water temperature.
    • Pressure valve issues. Hissing sounds or visible water escaping from the pressure relief valve.

    If you notice any of these signs, it’s essential to address the issue quickly to prevent further damage or water heater failure. Contact us for a professional inspection and repair service!

    Do you offer 24/7 emergency services for plumbing leaks?

    Yes, we offer 24/7 emergency plumbing services for leaks. Plumbing issues can occur at any time, and we are here to help whenever you need us, day or night. Whether it’s a small drip or a major leak, our team is ready to respond quickly and provide efficient repairs to prevent further damage.
