Keep people out and stop using drains
If water is coming from a floor drain or contains sewage, keep occupants and pets away. Do not flush toilets or run sinks, laundry, or dishwashers because additional discharge can worsen a surcharge. Avoid contact with the water and do not enter if electrical or gas hazards may be present.
Contaminated porous material is not dried in place
Carpet, underpad, low drywall, insulation, and other absorbent finishes exposed to sewage generally require controlled removal. The goal is not to make a contaminated surface look clean; it is to remove material that cannot be safely restored, clean the remaining structure, and prevent cross-contamination into unaffected rooms.
Cleaning and drying are separate steps
Extraction and removal reduce the contamination load. The exposed structure is then cleaned and treated as the site conditions require, followed by controlled drying. Moisture readings confirm that framing and other retained materials are ready for repair rather than being closed while still damp.
Plan prevention after the emergency is stable
The City of St. Catharines Flood Alleviation Program may help eligible homeowners with approved backwater valves, sump systems, and related work. Eligibility and approval must be confirmed with the City before work begins. We keep the emergency cleanup scope separate from any later plumbing or prevention project.
