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 certified technicians conduct a detailed on-site evaluation of your plumbing system, assess water table conditions, and handle all necessary permit applications to ensure a compliant installation.
We excavate the optimal location and install a CSA-approved backwater valve. For 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.
The system is rigorously tested under simulated heavy rainfall conditions, followed by a thorough final inspection and assistance with municipal rebate applications (up to $1,250).
We provide comprehensive maintenance guidelines and prompt emergency service to ensure continuous, reliable operation.

Our experts assess your water table and drainage conditions to recommend the optimal valve—installing an exterior valve with concrete sealing for high water tables or a full port (ball) valve for lower water tables.
Yes, all our backwater valves are CSA-approved and installed in strict compliance with Hamilton’s building codes.
