From Black Creek and Mount Dennis to Leslieville and the Danforth, most calls in this part of the city start at the floor drain during a summer storm. We clean up the backup, dry the house to standard, and then close the path it came in through. 24/7 Emergency Call (647) 277-6993 [tel:+16472776993 →](tel:+16472776993) Get My CAD Scope [#dispatch-form →](#dispatch-form) ![Three technicians unloading pumps and dehumidifiers from a restoration truck outside a post-war brick house](/images/misc/three-iicrc-technicians-unloading-pumps-and-dehumi.webp) Area File // Local Conditions SUBSIDY AREA Council: City of Toronto (old city, East York and York wards) Housing: Pre-1970 brick bungalows, semi-detached homes and two-storeys, many with original clay weeping tile and floor drains tied to combined sewers Typical trigger: Municipal sewer surcharge in summer storms pushing sewage up floor drains; spring-thaw seepage through older foundations Postal codes: M6N, M6M, M6P, M6R, M4C, M4J, M4G, M4K, M4M - 18 Years of Basement Flood Response - IICRC WRT, ASD, AMRT, CDS Certified - 24/7 Dispatch, 90-Minute Response - Insurance Direct-Billing - 5-Star Customer Satisfaction - WSIB + $5M Pollution Liability Early Warning Protocol // Local Risk Factors ## 7 Reasons Old Toronto and East York Basements Flood Every Storm Season Most Common Call // This Area FIELD PATTERN ### Sewage up the floor drain when the old-city sewer fills What you see: A summer cloudburst hits, and within the hour grey-brown water rises out of the basement floor drain and spreads under the rec room carpet. Why here: Much of the pre-1960 city drains through combined sewers, one pipe for sewage and stormwater. In storms like July 8 2013, when 126 mm fell at Pearson, that pipe surcharges and pushes back up the lateral to the lowest opening in the house. What we do: Sewage backup cleanup under IICRC S500 comes first. Then a camera inspection and a mainline backwater valve, so the next surcharge stops at the lateral instead of the rec room. 1. 01 ### Combined sewers under older streets Much of the old city drains stormwater and sewage through the same pipe. In a heavy storm the pipe surcharges and sewage pushes back toward the lowest opening, the basement floor drain. 2. 02 ### Floor drains tied to the sanitary lateral Pre-1970 houses usually have a floor drain connected straight to the sanitary line with no backwater valve in between. 3. 03 ### Clay weeping tile past its life Original clay tile around the footing shifts, cracks and fills with silt, so groundwater sits against the wall instead of draining. 4. 04 ### Foundation drains still feeding the sewer Many older homes still send weeping tile water into the sanitary line, adding to the load exactly when the system is full. 5. 05 ### Dense housing and little permeable ground Semis and row houses on narrow lots with paved lanes leave little ground for rain to soak into, so runoff reaches the sewer fast. 6. 06 ### Low-lying pockets near Black Creek and the Don Streets around Black Creek, Rockcliffe-Smythe and parts of the lower Don sit low in the local watershed and see water collect first. 7. 07 ### Freeze-thaw on older foundations Decades of freeze-thaw cycles open cracks and parging failures that let spring meltwater through the wall and the cove joint. Incident Archive // Local Storm Record ## July 2013, August 2018 and Why the Old City Keeps Backing Up On **July 8 2013**, close to 126 mm of rain fell on parts of the city in a few hours. The storm caused about **$850M in damage**, much of it in basements, and thousands of homes in the old city, York and East York took sewage through their floor drains. It was the event that pushed the city to expand its **Basement Flooding Protection Program**, the long-term infrastructure plan that upgrades sewers street by street across flood-prone areas. In **August 2018**, intense storms hit the west end again. The **Rockcliffe-Smythe** area, which sits in the **Black Creek** watershed, saw repeat sewer backups on the same blocks that had flooded before. Our crew handled 47 semi-detached homes on the Rockcliffe-Smythe blocks after that event, many of them for the second or third time. The pattern was the same in almost every house: sewage up the floor drain [/sewage-backup-cleanup-toronto/ →](/sewage-backup-cleanup-toronto/) , carpet and lower drywall contaminated, and no backwater valve on the lateral. The lesson from both storms is that in the old city, a basement flood in Toronto [/ →](/) is mostly a **sewer** problem rather than a river problem. **Toronto Water** is upgrading infrastructure, but that work takes years per neighbourhood. In the meantime, the protection that works house by house is a mainline backwater valve [/backwater-valve-installation-toronto/ →](/backwater-valve-installation-toronto/) , disconnected foundation drains and a sump pump [/sump-pump-installation-toronto/ →](/sump-pump-installation-toronto/) , which is exactly what the city subsidy is designed to help pay for. - \[EVENT LOG\] July 8 2013 storm: about $850M in damage, thousands of flooded basements - \[EVENT LOG\] August 2018 Rockcliffe-Smythe flooding: repeat sewer backups; the crew handled 47 semi-detached homes on the Rockcliffe-Smythe blocks Storm-night dispatch on a residential street Readings logged for the adjuster Directory // Services Dispatched Here ## The 4 Services Old-City Homeowners Book Most, Plus 8 More We serve the old city, East York and York, from Rockcliffe-Smythe and Keelesdale to Leaside, Riverdale and Parkdale.

For west-end calls in **Keelesdale, Mount Dennis, Black Creek and Weston** we typically come in along **Eglinton Avenue West** and **Black Creek Drive**, which also keeps us close to the Humber River crossings at **Scarlett Road**. East-end calls in **Leslieville, Riverdale, the Danforth and East York** are reached via the **Don Valley Parkway** and **Coxwell Avenue**, with Leaside a short run up Bayview. During major storms the DVP and parts of the Don Valley can close, and underpasses on the west side can flood. Dispatch plans routes around known trouble spots and gives you an honest arrival estimate rather than a hopeful one. Category 3 sewage calls are prioritised within the 90-minute window, and every truck carries pumps and a generator for outages. On narrow streets and lanes common in Riverdale, Parkdale and around **High Park**, we park so hoses reach the side door without blocking neighbours, and we bring portable extraction [/emergency-water-extraction-toronto/ →](/emergency-water-extraction-toronto/) for basement units that trucks cannot reach directly.

Below grade they share a few traits we plan for on every job: - **Pre-1970 clay weeping tile** that has cracked or silted up, so the cove joint leaks every spring [/basement-waterproofing-toronto/ →](/basement-waterproofing-toronto/) - **Floor drains tied directly to the sanitary lateral**, often cast iron or clay, with no backwater valve - **Foundation drains and downspouts** still connected to the sewer, which **Municipal Code Chapter 681** now requires most homes to disconnect - **Shared walls and shared laterals** on semis, where one neighbour's backup can affect the next house and the documentation needs to be clear about which side the water came from - **Low ceilings and finished basements** converted to rec rooms or rental units, which raise the cost of tear-out and rebuild [/basement-reconstruction-toronto/ →](/basement-reconstruction-toronto/) In low-lying areas near watercourses, the **TRCA** regulates some work close to valleys and floodplains. We check before any exterior excavation.

Rockcliffe-Smythe sits in the Black Creek and Lavender Creek floodplain, one of 10 Special Policy Areas in the Official Plan, and much of it is served by older sewers that surcharge in intense storms. When the system fills, sewage pushes back up laterals into floor drains. A mainline backwater valve, foundation drain disconnection and a sump pump are the house-by-house protection that works now. Eligible Rockcliffe properties can also apply for the city's Rockcliffe No Fault Grant, up to $7,500 per storm event for damage insurance did not cover. ### Is my East York home eligible for the Toronto subsidy? Yes, East York is part of the City of Toronto, so qualifying installations can receive up to $1,700 CAD for a sump pump and up to $1,700 CAD for a backwater valve, up to $3,400 per property. The work needs a permit and a city inspection. We confirm eligibility for your specific property, file the paperwork and book the inspection. The award is decided by the city. ### How fast can you reach the old city during a storm? Our dispatch window is 90 minutes, and the old city is where our trucks are based. On nights like July 16 2024, when the Don River flooded and closed the DVP in both directions, dispatch routes around the closures and gives you an honest arrival estimate. Category 3 sewage is prioritised. ### Do older Toronto homes need a backwater valve? Most pre-1970 homes on combined or surcharging sewers benefit from one, especially if the house has backed up before. A normally open mainline valve on the sanitary lateral closes when the city sewer surcharges. We camera the line first to confirm location and pipe condition. ### What do sewage cleanup and a backwater valve cost in the old city? Emergency dispatch is $250-$500 CAD, waived on same-visit extraction. Sewage cleanup under IICRC S500 is $2,000-$10,000 CAD, drying $1,500-$5,000 CAD. Prevention is a backwater valve at $2,500-$5,000 CAD and a sump pump at $1,200-$2,500 CAD, each eligible for up to $1,700 CAD in subsidy on qualifying installations. ### Do you handle semi-detached homes with shared drains? Yes, often. On semis we document which side the water entered from, check whether the lateral is shared, and coordinate with the neighbour where needed. Clear documentation keeps each household's claim separate. ### Should I report a sewer backup to the city? Yes. Call 311 Toronto to report it so Toronto Water can check the municipal sewer. The city does not clean private basements, so book cleanup at the same time. ### Do I have to disconnect my downspouts? Most homes are required to under Municipal Code Chapter 681, unless the city grants an exemption. Disconnecting downspouts takes roof water out of the sewer during storms and is a low-cost step to pair with a backwater valve. Question not covered here?
