Basement Flood Toronto Cleanup
Basement flood Toronto cleanup begins with extraction, but the part that protects your house is what happens behind the walls over the next few days.
Fully licensed and insured
Open 24 hours, 7 days
What gets removed and what is saved
Carpet and underpad that sat in storm or sewer water are removed. Drywall is cut above the water line, often 30 to 60 cm up the wall, so the insulation behind it can be checked. Laminate and vinyl plank are lifted where water went underneath. Solid furniture and many hard-surface belongings can be cleaned and kept.
We photograph and list everything that leaves the house so your claim has a record. Cleanup is the beginning: we dry the basement and rebuild it, and we bill your insurance company directly.

Older and newer Toronto basements
- Pre-war houses: stone foundations, low ceilings, old plaster
- 1950s to 1970s: block and poured walls, finished with panelling or carpet
- Newer builds: poured concrete, walk-outs, sump pits
- Basement apartments: kitchens and bathrooms that add more fixtures to the drain
Why speed matters
Wet drywall and insulation hold water against framing. Within a couple of days, damp materials can start to grow mould, and carpet that has sat in contaminated water is not worth saving. Starting extraction the same day keeps the damage to the lowest part of the wall and often saves finishes higher up.
Even if the water has drained away, a moisture check shows whether the building is actually dry. The readings also support your claim.
The first hour
Check that the power to the basement is off before you step into water. Carry out small items that are dry, lift anything electrical off the floor and photograph the water line. If the water arrived through the drain, do not run taps or flush toilets upstairs. Then phone us. A crew arrives with pumps, wet vacuums, air movers and dehumidifiers and starts extraction. The sooner the water is gone, the less drywall, trim and insulation has to come out.
Mention whether you have a finished ceiling. Water can pool above drop ceiling tiles and release later.
Signs of hidden moisture after a flood
- Baseboards that swell or lift away from the wall
- Floors that cup, ripple or feel cold
- Musty smell that comes back overnight
- Paint that blisters above the old water line
- Readings that stay high on a thermal image after the visible water has gone
Protecting the basement after the cleanup: City of Toronto limits
Once a flooded basement is dry, the next question is what prevents a repeat. Toronto's subsidy program pays up to 80 percent of the invoice for eligible protection work completed on or after 12 November 2025: a plumbing assessment to 500 dollars, a backwater valve to 1,600 dollars (two valves at most), a sump pump with alarm to 2,250 dollars, a battery backup to 300 dollars and weeping tile severance and capping to 400 dollars. The property total is capped at 6,650 dollars. These are the City's program limits, not our prices; our assessment is free and a written scope and price come before any repair work.
Keep the cleanup invoice and the protection invoice separate, so that the eligible items stand alone. The program is open to registered owners of single-family homes, duplexes, triplexes and fourplexes, and funding is first come, first served.
Cleanup questions
Can I wait until the insurer calls back?
Waiting lets damage spread. You can start mitigation and open your claim at the same time.
What about my belongings?
We can move, block up or pack out contents and list them item by item.
