Whether you’re on the lakefront in Aldershot, raising a family in Brant Hills, or in the townhomes of The Orchard, a city approved backwater valve is your best defense against sewage backup and water damage. At Waterproofing4Less, our licensed technicians handle every detail—from valve installation to rebate applications—then integrate with our sump pump installation in Burlington and basement waterproofing in Burlington services for total flood protection.
Burlington’s mix of heritage homes in Downtown Burlington, family neighbourhoods in Maple, and estates near Spencer Smith Park sits atop clay rich soil and aging sanitary sewers—prime conditions for basement flooding, contaminated water, and expensive repairs. Seasonal downpours and rapid snowmelt can overwhelm local lines, causing raw sewage to backflow into low lying basements.
At Waterproofing4Less, our backwater valve installation in Burlington uses industrial grade check valves and user friendly access panels, fully compliant with regional codes. We build a multi layered flood protection system—so you never have to worry about sewage backup prevention or mold growth again.
At Waterproofing4Less, we rely on premium materials and cutting‑edge technology to deliver
optimal performance:
We install top-performance sump pumps from trusted brands such as Zoeller or Liberty, ensuring efficient water removal.
Our systems include battery backup options and smart sensors to maintain operation during power outages—a critical feature for Toronto’s extreme weather.
We use infrared cameras, moisture meters, and drain cameras to detect hidden water intrusion and assess basement conditions with precision.
We strictly follow all local bylaws by conducting utility locates (for hydro, gas, Bell, Rogers, etc.) prior to excavation, protecting you from potential fines of up to $12,000.
Our licensed technicians perform a detailed on-site evaluation of your plumbing system, assess water table conditions, and manage all necessary permit applications to ensure a compliant installation.
We excavate the optimal location and install a CSA-approved backwater valve. For homes with high water tables, we position the valve inside the building with concrete sealing; for lower water tables, we install our preferred full port (ball) valve for zero-maintenance protection.
We rigorously test the installed valve under simulated heavy rainfall, conduct a thorough final inspection, and assist with municipal rebate applications of up to $1,250.
We provide comprehensive maintenance guidelines and prompt emergency service, ensuring your backwater valve operates reliably year-round.
Prevents hazardous sewage intrusion and basement flooding, safeguarding your foundation and indoor spaces.
