    During my bathroom renovation, I trusted Superior Plumbing & Heating to handle all plumbing installations. Sarah coordinated the appointments seamlessly, and the technicians ensured the shower fixtures, vanity plumbing, and drainage connections were installed flawlessly. Everything lines up perfectly, and there were no delays. Communication throughout the project was excellent, which made the whole renovation process much easier.

    I needed a small but urgent plumbing repair, and Superior Plumbing and Heating Bowmanville handled it professionally. The technician explained what caused the issue and how to prevent it in the future. Everything was fixed the same day.

    I had a badly clogged shower drain and called Superior Plumbing Belleville, and I’m so glad I did. They were quick to respond, showed up on time, and fixed the issue efficiently. The plumber was professional, explained what caused the clog, and made sure everything was draining perfectly before leaving. Fair pricing and excellent service from start to finish. I’ll definitely call them again for any plumbing issues and highly recommend them to anyone in Belleville!

    The plumber from Superior plumbing tried to sell us an expensive toilet replacement when all that was needed to fix the slow flush refill issue was a fill valve replacement. We got an inspection and issue was fixed by another plumber with just a fill valve replacement to fix the slow flush refill. Superior plumbing charged me a visit fee of ~$168.37 to take a look at the issue and said it would be applied to service cost if we went forward with them which is something not all plumbers so, but I still asked them to visit and take a look as they had positive reviews. But when the plumber came and visited and tried to upsell a toilet replacement and said they’ll have to go back for parts and quotes a very high fee, we decided not to go forward with them as we felt an unnecessary expensive service of toilet replacement was pushed when the fill valve replacement could have fixed the issue which indeed ended up being the case when the other plumber took a look later and fixed the issue. The positive was that they called in advance and came promptly during their scheduled visit time and call/scheduling coordinator was helpful but the unnecessary upsell from the plumber was a negative. The management followed up later to collect feedback and offered a visit fee refund (that I paid right after the visit), for my negative experience later which I did not receive for a few days since the promise. Update Feb 10 (4-5 days after service request): They called me today and said, refund was in process (earlier they said 10, now they said 15 business days to process) but said if you are going to add a review then they will not issue a refund. Unethical from a business point of view to coerce or quid-pro-quo remove a review by withholding service fee. They tried to upsell a full toilet replacement when all that was needed was a full valve replacement and then try to push me to remove the review by threatening to withold a refund they initiated. I declined the refund, if it was on the pre-condition of removing my review. Update Feb 27: Regardless of the Feb 10 conversation, they did finally issue the full refund today, without further communication and coercement. I take it that they finally understood the shortcomings of the service and support and took steps to address it, which is a positive sign. I see shortcomings overall in communication and with unnecessary upsells, but I appreciate the fact that the management made efforts to collect feedback, contact me to understand the issue, and ultimately issued a full refund when the service was not up to the mark.

    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.

    Montreal septic tank replacement cost

    Superior Plumbing & Heating performs numerous services for residential households and commercial locations across rural areas of Montreal. In particular, we have vast and robust experience in maintaining septic systems of any kind. If you assume that your septic tank requires repairs or replacement – call us now, and let’s sort out the situation together.

    What are the signs of a septic tank malfunction?

    Septic systems are primarily complicated and rather expensive, but at the same time durable and long-lasting. With proper maintenance, your septic system shall not bother you for 20 to 30 years. Unfortunately, emergencies and unexpected troubles happen from time to time, like with any other fixtures and appliance. When the problem comes up, it is critically important to determine its origin and figure out a plan for further actions.

    If we separate the wheat from the chaff, it could be stated that the only reason for urgent replacement is a tank crack. A damaged tank will unavoidably drain your waste into the soil before the digestion happens, polluting the groundwater, and that’s no joke.

    The common signs that your septic tank is damaged critically are the damp spots and foul odour in your tank location area. Fast-growing and greener grass can also be considered as a reason for concern.

    How to prevent your tank from cracking

    • If you are planning a septic tank replacement and have no wish to return to this process in the near future, choosing the modern fibreglass tank is recommended instead of old concrete or cheap plastic ones. This material is much less prone to damage and will definitely last longer than analogs.
    • Avoid heavy machinery impact. Mark your tank location and do not allow heavy trucks or other vehicles to cross it.
    • Pump the sludge layer regularly. As your septic tank is functioning, it breaks the wastewater into two fractions – solid and liquid. The liquid part travels to the leach field and is drained into the soil, while solid waste drowns to the bottom of the tank and forms a sludge layer. This waste should be removed once in a couple of years (depending on your tank and your family size). If you let the layer grow, it will increase the pressure inside the tank, reduce its pass-through capacity and lead to leaking.

    How much does the septic tank replacement cost

    There are too many different septic systems technologies and septic tank materials and sizes to state the firm figure on the costs. However, our experience tells us that replacement may probably cost you from 10 to 30 thousand on average.

    To conclude the exact estimate, it is necessary to arrange an appointment with a licensed plumber at your location to pre-inspect the whole system and determine what kinds of tanks are suitable.

    You also shall not forget to get a permit for septic tank replacement before proceeding to the plumbing works.

    Septic tank alternatives – does it worth it?

    Septic systems are being used in case there’s no opportunity to connect the household with the municipal sewer line. The only existing alternative for them is their predecessors – the cesspools. But that obsolete technology can hardly be called an alternative to septic systems – it’s a rudiment.

    If you construct a new dwelling in a rural area with no reach for the main sewer line – a septic system is your only appropriate option.

    So if you have decided to replace your septic tank, we will be pleased to help you. Contact our phone support experts to receive a consultation on the subject and get the job done nice and clean!
