Toronto’s aging sewer infrastructure can lead to unexpected sewage backups. Waterproofing4Less installs city-approved backwater valves that protect your property and help you qualify for Toronto’s subsidy program.
Toronto’s urban environment, characterized by heavy rains, rapid snowmelt, and aging municipal sewer systems, presents unique challenges that can lead to hazardous sewage backups. At Waterproofing4Less, we specialize in backwater valve installations tailored for Toronto homes. With over 25 years of local expertise and award-winning service, we protect your property from contaminated water intrusion while helping you secure rebates up to $1,250.
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 installation process is designed specifically for Toronto’s unique challenges and includes
four streamlined steps:
Our licensed technicians perform 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 install an exterior valve inside the building with concrete sealing; for lower water tables, we use our preferred full port (ball) valve—ensuring maximum efficiency.

A backwater valve is a one-way device installed on your sewer line that allows wastewater to flow out while preventing reverse sewage backflow during heavy rains or system overloads.
Due to heavy rainfall, rapid snowmelt, and aging sewer infrastructure, Toronto homes are at risk of sewage backups that can cause extensive water damage and health hazards.
It prevents sewage intrusion, protects your foundation, reduces costly remediation, and may qualify you for municipal rebates and insurance discounts.
Our certified technicians assess your water table conditions and drainage needs to recommend the optimal valve type—installing an exterior valve for high water tables or a full port (ball) valve for lower levels.
Yes, all our installations use CSA-approved valves that comply with municipal building codes in Toronto.
Absolutely, we help homeowners claim up to $1,250 in municipal rebates, making our solutions cost-effective.
While the duration depends on your home’s specific requirements, our streamlined process is designed for efficiency and minimal disruption.
