New installs, replacements and battery backups for Toronto basements.
Basement flooding can cause extensive property damage and health hazards. A professionally done sump pump installation is one of the most effective ways to prevent water accumulation and protect your home. At POM Plumbing, we provide dependable sump pump installation services across Toronto, ensuring long-term safety and peace of mind.
Our licensed team installs new systems, replaces worn pumps and adds battery backups, check valves and alarms. Every Toronto sump pump installation starts with a look at the basement, the pit and the route for the discharge pipe, and ends with a full test of the system.
Toronto homeowners can get most of the cost back through the City's Basement Flooding Protection Subsidy Program. For work completed on or after November 12, 2025, the City pays up to 80% of the invoice for a new or replacement sump pump, with a separate amount for a battery backup.
| Eligible work |
| New or replacement sump pump, including sump pump alarm installation |
| Battery backup for the sump pump |
| Backwater valve, up to two |
| Home plumbing assessment |
| Weeping tile (foundation drain) severance and capping |
The subsidy is only paid when the paperwork is right. On every eligible job we:
The same program pays toward a backwater valve installation, which stops sewer water from coming back up through the floor drain.
We prepare the invoice and photos the City asks for.
Storms in Toronto often bring a double threat: heavy rainfall and sudden power outages. A standard pump runs on household electricity, so it stops the moment the power cuts out, and that is when the pit fills fastest.
A sump pump battery backup sits in the same pit, slightly above the main pump. Its own float switch turns it on if the power fails or the primary pump can't keep up with the inflow. We also connect an alarm that sounds when the backup starts, so you know the main pump needs a look.
We install backups with new systems and add them to existing pumps that still work well. The City pays up to $300 toward the backup on top of the pump subsidy, as long as it is a separate line on the invoice. Compared with the bill for flood restoration after one wet basement, it is one of the cheapest parts of the whole system.
A sump pump is not just a preventive measure; it’s an essential component of a dry and secure basement. Here are situations that demand immediate action:
Calling a licensed plumber early helps avoid thousands of dollars in water damage repairs. If your old unit has failed or can’t keep up, a sump pump replacement is the next logical step.
Most Toronto basements get one of two pump types. We recommend one after looking at the pit size, how often water comes in and whether the basement is finished.
| Submersible pump | Pedestal pump | |
| Where the motor sits | Inside the pit, under water | On a column above the pit |
| Noise | Quiet, the water muffles the motor | Louder, the motor is in open air |
| Clogging | Less likely to clog | More sensitive to debris in the pit |
| Servicing | The pump is lifted out of the pit | The motor is easy to reach |
| Best fit | Finished basements, pits with heavy inflow | Unfinished utility rooms, narrow pits |
We handle submersible sump pump installation in finished basements, where a quiet pump and a sealed lid matter. Pedestal sump pump installation still makes sense in an unfinished utility room or a pit too narrow for a submersible model. If an old pedestal unit is loud or keeps clogging, we can swap it for a submersible one in the same pit when the pit is wide enough.
Our process is transparent, efficient, and tailored to your property’s needs. A typical job includes the following steps:
Each step is handled by certified professionals following Ontario plumbing regulations.
Want to know what your basement needs?
Most homeowners want a number before they book. The ranges below reflect typical jobs in Toronto and the surrounding suburbs. Your final price is set after we see the basement, the pit and the route for the discharge line.
Several factors play into the price, from the pump type to the add-ons you choose:
Replacing an existing sump pump is generally less expensive than a full installation. On average, sump pump replacement cost ranges between CAD 350 and $1,000, depending on the complexity of the swap.
| Job Type | Estimated Cost (CAD) |
| Basic Replacement (existing setup) | $350 – $1,000 |
| Standard Full Installation (basement) | $1,200 – $2,500 |
| New Sump Pump Pit Installation With Concrete Cutting | $2,500 – $3,500 |
| Basic Pump Unit Alone | $60 – $400 (depending on type) |
The City pays up to 80% of an eligible invoice, capped at $2,250 for the pump and alarm and $300 for a battery backup. On a $2,000 installation, 80% comes to $1,600, so your share would be $400 if the home qualifies. Replacement is covered by the same program, which lowers the cost to replace a sump pump in the same way.
We understand that budget matters. That’s why on every job we:
Get a written price for your basement.
Old or underperforming sump pumps can fail at the worst possible moment. Here’s how to know it’s time for a sump pump replacement:
Replacing a sump pump takes more than dropping a new unit into the pit. On every replacement we:
If the motor is still in good shape and only the switch fails, a sump pump float switch replacement is often enough. We will tell you so before quoting a new pump.

When a pump fails in the middle of a storm, the next few hours decide how much water ends up on the floor. Our crews cover Toronto, Mississauga, Vaughan, Etobicoke, Scarborough, North York and the rest of the GTA.
Emergency sump pump replacement goes to the front of our schedule when water is already rising in the pit. Planned work, like adding a backup before spring, is booked at a time that suits you.
Either way, you get the same licensed team, a written estimate before work starts and a clean basement when we leave.
Not every contractor sizes the pump to the basement or routes the discharge the way the City expects. When you hire POM Plumbing, you get:

Most standard installations can be completed in less than a day, depending on the layout of the basement and the existing plumbing infrastructure. In cases where additional drainage work is required, such as creating a sump pit or rerouting discharge lines, the process may take longer. At POM Plumbing, we aim to complete the job efficiently without compromising quality or code compliance.
A straight swap in a pit that is in good condition is usually finished in a few hours. If the liner, check valve or discharge line also need work, the visit can take most of the day.
Plan on a new pump once the old one has been in service for about 7 years, or sooner if it runs nonstop, grinds or stops mid-cycle. Pouring a bucket of water into the pit each spring shows whether the pump still starts and empties the pit quickly.
Yes, if the pump still works well and the pit has room for a second pump. When the pit is too narrow, we can fit a wider liner during the same visit.
Yes. We open only the section of floor needed for the pit, usually in a utility room or under the stairs, and patch the concrete after the pump is in. A submersible pump with a sealed lid keeps the finished space quiet.
Owners of single-family homes, duplexes, triplexes and fourplexes in Toronto. The downspouts must be disconnected from the City sewer, and the application has to be filed within two years of the installation.
No. A sump pump removes groundwater that collects around the foundation. Sewer water coming back through a floor drain is stopped by a backwater valve. Many Toronto homes need both, and the City subsidy covers each of them.
While it may seem straightforward, installing a sump pump involves knowledge of local plumbing codes, electrical safety, and waterproofing techniques. Improper installation can lead to pump failure, basement flooding, and even safety hazards. It’s strongly advised to have the work performed by licensed professionals to ensure everything is correctly and safely configured.
