Luciano did not try to sell me a new roof. Appreciated the honesty — he showed up when he said he would.
We had a leak diagnosed by two other contractors who could not find the source. Blue Knight found it on the first visit and fixed it the same week.
Flat roof replacement on a commercial unit. Clean, fast, no surprises on the invoice. The crew left the site cleaner than they found it.
Called after a storm damaged our roof. Someone was on site within hours, tarped everything, and had us fully repaired before the next rain.
Had a slow basement leak for years. Every other company just caulked it. Blue Knight found the actual source and did a proper waterproofing job. No issues since.
Our neighbours recommended them for a valley repair. Small job, but they treated it like it mattered — showed up on time, matched the shingles perfectly, and charged exactly what they quoted.

Flooding response questions.
We target on-site within 60 minutes for active flooding situations across the GTA. For active flooding, call (647) 383-8664 directly, phone dispatch is faster than any online form.
Turn off the water supply if it's a burst pipe. Do not enter standing water if there's any chance of electrical hazard, switch off the circuit for the affected area at the panel first. Move valuables if it's safe.
Overland flooding is covered under overland flooding endorsements (many Ontario homeowners carry these since 2013). Sudden internal flooding (burst pipe) is typically covered under standard policies. Gradual water entry is typically excluded. We document the source and timing of the event from first arrival, this is the foundation of your claim.
Yes, but timing is critical. Mould can begin colonizing porous materials within 24-48 hours of water saturation. Industrial dehumidification and air movement started within 24 hours of water removal significantly reduces mould probability.
Timestamped photos of all affected areas, written description of the source and path of water entry, extent of saturation, materials affected, immediate actions taken, and recommended permanent repair scope. Delivered the same day, formatted for Ontario insurance adjusters.
What GTA Homeowners Ask During a Flooding Emergency.
From what to do right now to what your insurance covers, answered by 25-year GTA emergency specialists.
We target on-site within 60 minutes for active flooding in the GTA. Toronto, North York, Scarborough, Etobicoke, Mississauga, and Brampton. For active flooding with ongoing water entry, call (647) 383-8664 directly. Phone dispatch is faster than any online form.
Priority one: safety. If there is any possibility of electrical hazard in the flooded area, turn off the circuit at the panel before entering. Turn off the water supply if it's a burst pipe. Call for emergency response immediately. Move critical documents and electronics if it can be done safely. We will be on site within 60 minutes to stop the entry and begin extraction.
Yes. We operate a 24/7 emergency line for active flooding, structural failures, storm damage, and fire response across the GTA. We answer at 2am, on weekends, and during active storm events. Emergency response is our highest-priority service. Call (647) 383-8664.
It depends on the source. Overland flooding is covered under overland flooding endorsements, these must be added to standard Ontario home insurance and many homeowners added them after 2013. Sudden internal flooding (burst pipe) is typically covered under standard policies. Gradual water entry from failed drainage is usually excluded. We document the source on arrival, this determines what claim you file.

- Does insurance cover flooding damage in Toronto?
- It depends on the source. Overland flooding is covered under overland flooding endorsements, these must be added to standard Ontario home insurance and many homeowners added them after 2013. Sudden internal flooding (burst pipe) is typically covered under standard policies. Gradual water entry from failed drainage is usually excluded. We document the source on arrival, this determines what claim you file.
- What documentation do I need for a flooding insurance claim in Ontario?
- Timestamped photos taken immediately (ideally before any mitigation begins), a written description of the source and path of entry, receipts for emergency mitigation work, and a written damage assessment from a qualified contractor. We provide all of this as standard output from our emergency response. The faster you call, the more complete your documentation timeline.
- How long do I have to file a flooding insurance claim in Ontario?
- Most Ontario insurers require notification within 24-72 hours of the event. The formal claim submission window is typically 12 months, but delay in notification weakens your claim, especially for overland flooding where the event date and source need to be documented before the scene changes. Call your insurer and your contractor the same day.
- How is standing water removed from a basement in Toronto?
- We use truck-mounted or portable extraction equipment capable of removing significant volumes quickly. After bulk extraction, residual moisture in structural materials requires industrial dehumidification and air movement equipment to dry to safe levels. Household wet-vacs and mops cannot achieve the drying rates needed to prevent mould within the 24-48 hour window.
- How long does water extraction take after basement flooding?
- Bulk extraction of standing water in a standard GTA basement typically takes 1-3 hours depending on volume and access. The drying phase, industrial dehumidifiers and air movers on saturated structural materials, takes 3-7 days of continuous operation. We monitor daily with moisture meters to confirm materials are drying to acceptable levels.
- Can I use my basement after water extraction in Toronto?
- Not fully until structural drying is confirmed complete by moisture meter readings. Drywall, framing, and insulation that appears dry to the touch may still have unacceptable moisture levels that support mould growth. We confirm drying is complete before signing off. The affected zone should not be reconstructed until moisture content is verified.
- How quickly can mould grow after basement flooding in Toronto?
- Mould can begin colonizing porous materials, drywall, wood framing, carpet, insulation, within 24-48 hours of water saturation at indoor temperatures. The 24-hour response window for professional extraction and drying startup is the critical threshold. Flooding not professionally dried within 24-48 hours of water removal has meaningfully higher mould remediation probability.
- How do I prevent mould after flooding in my Toronto home?
- Get professional extraction and industrial drying started within 24 hours of water removal. Remove saturated porous materials (drywall, insulation, carpet) that cannot be dried effectively. Maintain high air circulation and dehumidification for the full drying period. Do not close up the affected area while drying is in progress, airflow is essential.
- Is mould remediation included in flooding response?
- Mould remediation and flooding response are separate scopes. Our emergency flooding response focuses on water containment, extraction, and structural drying, the actions that prevent mould from forming. If mould has already colonized (typically when response is delayed beyond 48-72 hours), remediation requires a separate specialist scope. We assess for mould presence on arrival and flag it in the damage report if found.
- What are the most common causes of flooding in Toronto homes?
- The most common in the GTA: (1) Overland flooding during severe rain events. Toronto's storm sewer capacity has been repeatedly exceeded in summer storm events; (2) Sewer backup, especially in older flat areas of the city; (3) Burst pipes from freeze-thaw events; (4) Foundation drainage failure during spring snowmelt; (5) Appliance failures. Each has different insurance coverage and different permanent repair paths.
- Why do Toronto basements flood in heavy rain?
- Toronto's combined storm sewer system, designed for 1950s rainfall patterns, is frequently overwhelmed by modern storm events. During intense rainfall, storm water enters sanitary sewers through overland flow or cross-connections, causing backpressure that forces water back through basement floor drains. Backwater valves and sump systems are the primary mitigation.
- What is overland flooding and how does it affect Toronto homes?
- Overland flooding is surface water entering a building by flowing over the ground, rather than through a backed-up sewer. Standard home insurance does not cover overland flooding, it requires a separate endorsement that became widely available after 2013. We document the path of water entry on arrival, which determines whether the event qualifies as overland flooding for insurance purposes.
- Does Toronto clay soil cause basement flooding?
- Toronto's heavy clay soil holds water rather than absorbing it, which increases surface runoff and hydrostatic pressure on foundations during rain events. The spring thaw is the highest-risk period, fully saturated clay from winter has essentially zero additional capacity. Clay soil is a contributing factor in hydrostatic pressure seepage, but not a direct cause of flooding events.
