    What is sewer backup?

    Sewer backup happens when the city or municipal drainage system overflows and sends water back through the pipes and into your home or office. Possible causes include heavy rainfalls, or a failure of a sump pump to deal with excess water. The water and sewage may come from a septic tank, sewer, or storm drain. Backup can cause a lot of damage, such as mold and bacteria problems. It requires an immediate clean-up by professionals specializing in sewage backup cleaning in Mississauga and Toronto.

    Most common causes:

    • Sewage backflow: a flow of water in the wrong direction.
    • Lateral drain & drain stack clogs: a clog in the pipe that runs across your property boundaries, often on a shared sewer.
    • Main drain/sewer line clog: if the clog is in the main line, any water you run will cause problems.

    Infrared camera detection

    Infrared inspection is a quick, non-invasive method of discovering moisture intrusion. Our skilled specialists use a cutting edge technique called Infrared Thermography (IT) to detect and eliminate mold infestations. IT can clarify the source of a leak based on water temperature.


    Commercial sewage backup cleaning in Toronto is our expertise. But prevention is always best. Several things you can do to prevent sewer backup: install sump pumps and check them regularly, have backflow valves installed in your home or office, make sure your property has good drainage, have plugs on hand for all drains and toilets.
