Reliable sump pump systems with battery backup to protect your basement from flooding and water damage.
A sump pump is your basement's last line of defense against flooding. Installed in a pit (sump basin) at the lowest point of your basement floor, it automatically activates when water reaches a set level and pumps it out through a discharge line away from your foundation. In Toronto, where heavy spring rainfall and rapid snowmelt can push thousands of litres of groundwater against your foundation in a single day, a properly sized and installed sump pump is not optional — it's essential infrastructure.
Many Toronto homes built before the 1990s were constructed without sump pumps, relying instead on gravity-fed weeping tile that drained to the municipal storm sewer. Since Toronto separated its storm and sanitary sewer systems, that connection is no longer permitted in most areas. A sump pump is now the required method for managing foundation drainage water in homes across the GTA.
Why Choose Us
The single biggest risk with sump pumps is failure during a storm — exactly when you need them most. Power outages during severe weather are common in Toronto, and a primary pump without battery backup is useless when the electricity goes out. We've responded to hundreds of emergency calls from homeowners whose basements flooded because their sump pump had no backup, or because the backup battery hadn't been maintained and failed when it was finally needed.
Every sump pump system we install includes a battery backup as standard — not an optional upgrade. The backup unit sits alongside the primary pump and activates automatically within seconds of a power loss. On a full charge, it operates for 8-12 hours of continuous pumping, which is enough to handle most Toronto storm events. We also install a high-water alarm that alerts you audibly if water rises above the normal activation point.
Don't Ignore the Signs
Proper sump pump installation is more than dropping a pump in a hole. We excavate a sump pit that is appropriately sized for your home's water volume — typically 18-24 inches in diameter and 24-30 inches deep. The pit is lined with a perforated sump liner that allows groundwater to enter from all sides while keeping sediment out. The discharge line is routed through the foundation wall and extended at least 6 feet from the house, with a check valve to prevent backflow. In freezing conditions, we install a freeze guard that redirects water to a surface outlet if the underground discharge line freezes.
We use only commercial-grade pumps from Liberty and Zoeller — brands rated for continuous duty that can move 2,500-3,500 gallons per hour. Consumer-grade pumps from hardware stores are rated for intermittent use and typically fail within 3-5 years. Our pumps carry manufacturer warranties of 3-5 years, and we warranty the full installation for 5 years.
If you already have a sump pump that's more than 7 years old, it's approaching the end of its reliable service life. Signs that replacement is needed include the pump cycling on and off frequently, running continuously without shutting off, making grinding or rattling noises, or visible rust on the pump housing. We recommend proactive replacement before failure rather than waiting for an emergency — a planned replacement costs the same as an emergency call but doesn't come with the water damage cleanup bill.
Sump pump installation and replacement is one of the fastest waterproofing services we offer. Most installations complete in 4-6 hours, and replacements of existing systems take 2-3 hours. Toronto homeowners with sump pump installations may be eligible for rebates through the City of Toronto's Basement Flooding Protection Subsidy Program, which covers up to $1,250 toward the cost of a sump pump and associated plumbing work.
Materials & Methods
Commercial-grade Liberty or Zoeller submersible pump with cast iron or stainless steel housing, rated at 2,500-3,500 GPH for continuous-duty residential applications.
Independent backup pump with marine-grade battery that activates automatically during power outages. Provides 8-12 hours of continuous operation on a full charge.
A surface-level overflow fitting on the discharge line that redirects water to grade if the underground line freezes during Toronto's winter months, preventing pump burnout.
Audible alarm mounted above the sump pit that activates if water rises above the normal pump activation level — an early warning before flooding occurs.
Our Process
We evaluate your basement's water volume, drainage system, and existing setup to determine the right pump capacity, pit size, and discharge routing.
We excavate the sump pit at the lowest point of your basement, install a perforated sump liner, and connect it to your interior drainage system.
The primary pump and battery backup are installed in the pit with float switches set at proper activation levels. A high-water alarm is mounted for added protection.
The discharge line is routed through the foundation wall with a check valve, extended away from the house, and fitted with a freeze guard for winter protection.
We fill the pit to test both the primary and backup pumps, verify proper discharge, and walk you through the system operation and maintenance schedule.
