Priority DispatchServing The Beaches, Leslieville, Riverdale and more
Sump Pump Installation Toronto installs sump pumps, battery backups and sump + backwater valve combos across Toronto's east end, from The Beaches and Leslieville to Riverdale, the Danforth, East York and Thorncliffe Park. Lakefront lots with sandy soil and street runoff, century semis with finished basements and post-war bungalows all need a different approach, so we start every job with a camera scope and flow test. A licensed Master Plumber pulls the permit, installs to Ontario Plumbing Code Part 7 and files the City of Toronto subsidy for eligible addresses.

The Local Problem
What you see: In a heavy storm, dirty water comes up through the basement floor drain, sometimes while the walls are dry.
Why it happens here: Older east-end streets are on combined sewers, where rain and sewage share one pipe; when it surcharges, the overflow the Coxwell Bypass Tunnel is being built to catch finds your drain first.
What we do: A sump and backwater valve combo closes the drain against the sewer while a sealed sump handles the groundwater the valve keeps in.
The float sticks or the motor burns out halfway through a long storm, and water starts rising in a finished basement.
Storms that flood basements often take the power too, and a pump with no electricity is no help.
No permit, no inspection, a lump-sum invoice: the reasons City subsidy claims and insurer renewals stall.
Near the Beaches, sandy lakefront soil and street runoff push water toward foundations quickly, and many century semis in Riverdale have finished basements that were never designed with a sump in mind.
$5,500 - $9,500
Full $1,750 Max City Subsidy Applied
Backwater valve at the building drain plus a sealed sump and weeping tile redirect: both flood paths covered, full $1,750 subsidy.
$1,800 - $3,200
Eligible for $500 City of Toronto Rebate
New sump pit cut into your basement slab, sealed basin, cast iron pump and freeze-proof discharge, usually done in one day.
$900 - $5,100
Subsidy eligibility confirmed at assessment when part of a new sump install
Secondary 12V pump on a deep-cycle battery with its own float and WiFi alarm, so the pit keeps draining when the power goes out.
Every job here is run by the same licensed crew behind our Toronto sump pump installation service, with the same published pricing and City subsidy filing. Also available: weeping tile disconnection, replacement, 24/7 emergency repair, submersible upgrades, perimeter drains, insurance claim installs and City rebate filing.
We use our city-wide published ranges in the east end. A new interior sump pump installation runs $1,800 to $3,200 CAD, with most Toronto jobs at $2,400 to $2,800 before the $500 subsidy. Finished basements in century semis tend to sit toward the upper end because of tighter access and floor finishes.
A sump + backwater valve combo runs $5,500 to $9,500 and can qualify for up to $1,750 from the City on eligible addresses. A replacement in an existing pit runs $1,500 to $2,800. We file the subsidy at no charge.

"1970s bungalow sump died first April storm. Cast iron Zoeller installed same week, battery backup added. Dry through two more spring storms. Fair price and a tidy crew."
"After the July 2024 storm backed up our Rosedale basement, we went full combo: Mainline backwater valve, Zoeller M63 and Aquanot battery. Full $1,750 subsidy cheque arrived about seven weeks later."
"Cliffside bungalow with weeping tile into the sanitary line. They capped it, redirected to a sealed sump and added the backwater valve. Inspector signed off the same week."
The east end is old Toronto. Leslieville began as a village in the 1850s, and the narrow lots of Riverdale and the Danforth are lined with century semis whose basements were dug out long after they were built. Few were designed with a sump in mind.
Much of this area is still on combined sewers, where rain and sewage share a pipe. The City is building the 10.5 km Coxwell Bypass Tunnel to capture those overflows for Ashbridges Bay, and in the first half of 2015 Beaches-East York logged the second-highest number of basement flooding reports in Toronto.
Near The Beaches, sandy lakefront soil moves groundwater fast. Most jobs here pair a backwater valve for the sewer with a sealed sump for the groundwater, set in a corner of a finished basement with a lid flush to the floor.
What We Account For Here
The east end sits between the Don River and the Lake Ontario shoreline. Near the Beaches, sandy soil drains quickly, which sounds good, but it means groundwater reaches foundations fast during heavy rain and spring thaw. Surface runoff from sloped streets adds to it.
Further north, older neighbourhoods have combined sewers, and floor-drain backups during big storms are common. That is why many east-end jobs are combos: a backwater valve for the sewer, a sealed sump for the groundwater, and up to $1,750 back from the City on eligible addresses.
Century semis in Riverdale and Leslieville. Narrow, deep basements, often finished, with older plumbing and no sump. These basements were never designed with a pit in mind, so we plan the location around the room you actually use, finish with a flush sealed lid and keep dust in check.
Beaches lakefront homes. Sandy soil near the lake lets water move quickly, and street runoff on sloped blocks heads straight for foundations in heavy rain. Pits here need to catch water fast, and a dependable discharge is essential.
East York and Thorncliffe Park bungalows. Post-war and 1970s bungalows, often with an original plastic pump that has never been replaced. One of our Thorncliffe Park customers lost their pump in the first April storm; a cast iron Zoeller and a battery backup went in the same week.
Local Landmarks
Getting There
The Don Valley Parkway links the east end to the rest of the city, with Queen Street East, Gerrard and the Danforth as the local routes.
Routes: Don Valley Parkway, Gardiner Expressway, Lake Shore Boulevard East, Kingston Road
Transit: Broadview station, Main Street station, Danforth GO, Queen and Kingston Road streetcars
We cover the east end along Queen Street East, Gerrard, the Danforth and Kingston Road, with the Don Valley Parkway as the link to the rest of the city. Non-emergency assessments are usually booked within 2 business days, and the phone is answered live 24/7 for emergencies.
Many Leslieville, Riverdale and Beaches streets have narrow lots and street or permit parking. We confirm parking, side-door access and where we can stage the basin and stone at the assessment, so install day is not spent hunting for a spot. Drain permits are filed with Toronto Building, usually about 5 business days ahead, with inspections normally the same week as the install.
Neighbourhoods We Cover
Postal codes (FSA) we cover: M4C, M4E, M4H, M4J, M4K, M4L

Thanks, we got your request.
A member of the Sump Pump Toronto Crew will call you back, usually the same business day. Water rising right now? Call (437) 782-5911.
Yes. We choose a pit location that works with the finished room, cut under a dust shroud, protect floors and walls, and finish with a sealed lid flush with the floor.
Much of the east end is on combined sewers, where rain and sewage share one pipe. When it surcharges, water backs up the lowest drain, and a backwater valve is the fix.
It is built to keep combined sewer overflows out of the Don River and the harbour. It does not seal your own floor drain, so a backwater valve and sump are still worth discussing.
Combos run $5,500-$9,500 CAD. A new interior sump on its own is $1,800-$3,200, with tight century semis toward the upper end. We file the City subsidy at no charge.
Sandy lakefront soil and runoff from sloped streets move water to the foundation quickly. A properly placed pit and a dependable discharge route are the fix.
The Beaches, Leslieville, Riverdale, East York, the Danforth and Thorncliffe Park, using the Don Valley Parkway to reach them. Assessments are usually booked within 2 business days.
We confirm parking and access at the assessment, including permit parking if needed, so install day starts on time.
If it is plastic and more than 5-7 years old, yes. A cast iron replacement runs $1,500-$2,800 and typically lasts 15-20 years.
Yes. Most finished-basement jobs include a WiFi alarm, often paired with a battery backup, so you get a phone alert before water reaches the floor.
In the first half of 2015 the ward logged 209 basement flooding reports, second only to Etobicoke-Lakeshore. Older sewers and lakefront ground both contribute.
Honestly, that is the whole pitch. We would rather spend an hour at your house now than pump out a finished basement later.
