    Our old water heater finally gave out, and we called Superior Plumbing and Heating. From the initial quote to the installation, everything was seamless. They helped us choose an energy-efficient model, installed it neatly, and made sure we understood the maintenance tips before leaving. We’ve had consistent hot water ever since, and our utility bill has already improved. Great service and very knowledgeable team!

    I called Superior Plumbing Cobourg for a leaking kitchen faucet that was driving us crazy. They responded quickly, arrived right on time, and fixed the issue in under an hour. The plumber explained what caused the leak and even gave tips to prevent it in the future. Professional, friendly, and very reasonably priced. I wouldn’t hesitate to call them again!

    After noticing water pooling around my basement floor drain, I contacted Superior Plumbing & Heating for an evaluation. Ethan arrived promptly, cleared the blockage deep within the line, and confirmed proper drainage before leaving. The issue was resolved efficiently.

    Strange banging noises were coming from my heating system, which had me concerned. Superior Plumbing & Heating sent Kevin to investigate, and he carefully inspected the system before identifying air trapped in the pipes. After bleeding the system and making a few adjustments, the noise disappeared entirely. The heating now runs quietly and smoothly.

    Ryan the plumber did an excellent job fixing my clogged sink. He was quick, efficient, and clearly knew exactly what he was doing. He arrived on time, got straight to work, and had everything running perfectly in no time. The whole process was smooth and stress-free, and I really appreciated his professionalism and friendly attitude. I’d definitely recommend Ryan to anyone needing reliable plumbing work!

    A burst pipe in the basement late at night could have turned into a disaster, but Superior Plumbing & Heating responded quickly. Tyler arrived within an hour and immediately assessed the damage. He repaired the pipe efficiently and carefully checked nearby connections to prevent further issues. He also gave helpful advice on insulation to avoid future freezing. The quick action likely saved me from major water damage.
