In North York a basement flood often means two households: the owner upstairs and a tenant downstairs. We clean up, keep separate records for both claims, find the cracked drain line behind the backup, and rebuild the unit to code. 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 (Willowdale, Don Valley North, York Centre) Housing: Post-war bungalows with basement rental units, 1960s split-levels, infill homes beside older lots Typical trigger: Cracked or root-blocked aging cast-iron drain lines; storm backups into basement apartments Postal codes: M2N, M2M, M2R, M3H, M2P, M2K, M3B, M3C, M3K, M3M - 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 ## 6 Things North York Landlords Should Know Before the Next Basement Flood Most Common Call // This Area FIELD PATTERN ### One backup, two households: flooded basement apartments in post-war bungalows What you see: Water or sewage reaches the basement unit first, the tenant is displaced overnight, and the landlord is juggling two insurers and a rebuild. Why here: Most bungalows here went up after the Second World War, often with cast-iron laterals now 60 to 70 years old. Storms like August 19 2005, when Black Creek washed out Finch Avenue West, overload those lines and the lowest unit takes the water. What we do: Sewage backup cleanup with separate owner and tenant records for the insurance claim, then a permitted rebuild of the unit to code. 1. 01 ### Your policy and your tenant's policy are separate The landlord policy covers the building. The tenant's own contents policy covers their belongings. Both claims need their own documentation, which we keep separate from day one. 2. 02 ### Cast-iron drain lines fail from the inside Post-war cast-iron laterals in Willowdale and Bathurst Manor corrode, crack and catch roots. A camera inspection often finds the real cause of a backup. 3. 03 ### The Residential Tenancies Act still applies during repairs Tenants have rights around notice, access and habitability. Clear repair schedules and communication make the process easier on everyone. 4. 04 ### Rental units must be rebuilt to code Fire separation, egress, smoke alarms and ceiling height all matter when a basement apartment is rebuilt after a flood. Permits and inspections are part of the scope. 5. 05 ### Rental income loss may be claimable Some landlord policies cover lost rent while the unit is uninhabitable. The drying log and rebuild schedule support that part of the claim. 6. 06 ### Prevention pays twice in a rental A backwater valve and battery backup sump protect both households. On City of Toronto properties both can qualify for the subsidy. Incident Archive // Local Storm Record ## Cast-Iron Laterals, July 2013 and the Rental Basement Problem North York was built out fast after the war, and many of those bungalows still drain through their original **cast-iron drain line**. After 60 to 70 years, cast iron corrodes from the inside, cracks, and lets tree roots in. In **Willowdale** especially, that has produced repeat sewer backups [/sewage-backup-cleanup-toronto/ →](/sewage-backup-cleanup-toronto/) in the same post-war homes, sometimes without a storm at all. The **July 8 2013** storm added the other half of the story. Heavy rain overwhelmed sewers across the district, and water and sewage came into basements from Downsview to Don Mills. Low areas along the **Don River West Branch** saw overland water too. What sets this district apart is the number of **basement apartments**. A single backup can mean a displaced tenant, two insurance claims, a rental unit to rebuild to code [/basement-reconstruction-toronto/ →](/basement-reconstruction-toronto/) , and a landlord losing rent. We have worked for the **Willowdale Manor rental portfolio on Yonge Street** and many individual landlords, and the fastest files are always the ones where the tenant's contents log and the owner's building scope were kept separate from the first hour. - \[EVENT LOG\] Willowdale aging cast-iron drain lines causing repeat backups in post-war homes - \[EVENT LOG\] July 8 2013 storm flooding basements from Downsview to Don Mills Storm-night dispatch on a residential street Readings logged for the adjuster Directory // Services Dispatched Here ## Cleanup, Claims and Rebuilds for Owners and Landlords We serve North York from Willowdale, Newtonbrook and Lansing to Bathurst Manor, York Mills, Bayview Village, Don Mills and Downsview.

Many Willowdale bungalows were built in the post-war boom and still drain through original cast-iron laterals. Cast iron corrodes from the inside, cracks and lets roots in, which narrows the pipe and causes backups even on dry days. Storms add sewer surcharge on top. A CCTV drain camera inspection shows the actual condition, and the fix is usually a lateral repair plus a mainline backwater valve. ### Who pays when a basement apartment floods? Generally, the landlord's policy covers the building and the tenant's own contents policy covers their belongings, each subject to its own terms and deductibles. Some landlord policies also cover lost rent. We document both sides separately from the first hour so each claim can be handled on its own evidence, subject to each policy's limits and adjuster approval. ### Do you work with property managers on Yonge Street? Yes. We work with property management offices, including the Willowdale Manor rental portfolio on Yonge Street, with one coordinator on our side, scheduled tenant access and consolidated reporting. ### Is North York eligible for the Toronto subsidy? Yes. Since the 1998 amalgamation, North York properties fall under the Toronto program. A qualifying sump pump and a qualifying backwater valve can each receive up to $1,700 CAD, up to $3,400 per property, after a permit and city inspection. We check the address, file the forms and book the inspection; the city makes the final call. ### What does a cleanup plus a rental unit rebuild cost? Dispatch is $250-$500 CAD (waived on same-visit extraction), sewage cleanup $2,000-$10,000 CAD, drying $1,500-$5,000 CAD, and a backwater valve $2,500-$5,000 CAD. Rental unit rebuilds are quoted after mitigation, with partial rebuilds typically $4,000-$12,000 CAD. ### How fast can you reach Don Mills and Bayview Village? Both are inside our 90-minute dispatch window, reached via the DVP and Leslie Street. Category 3 sewage is prioritised. ### Can my tenant stay during the cleanup? It depends on the category and whether the unit is habitable. For Category 3 sewage in the unit itself, the tenant usually needs to stay elsewhere until cleanup and disinfection are done. We give landlords a written schedule to plan around. ### Does the rebuilt unit need a permit? Yes. Creating or rebuilding a secondary suite requires a building permit and inspections from Toronto Building, covering Ontario Building Code items such as fire separation, egress and smoke alarms. We check the scope and pull the permits that apply. Question not covered here?
