When Niagara Properties Need Sanitization
Sewer backups after summer cloudbursts
Between July 21 and August 2, 2026, three 100-year rain storms brought more than 300 mm of rain to St. Catharines, overwhelmed the city's sewer and stormwater systems, and led to a state of emergency. When sewers surcharge like that, water comes up through basement floor drains carrying sewage onto floors, walls, and stored belongings. Drying alone does not make those surfaces safe. We clean and disinfect before anything is rebuilt.
Finished basements and stored contents
Many homes across the Niagara Region and Hamilton use the lower level as living space or storage. Carpet, drywall, furniture, toys, and boxed items that sat in contaminated water need sorting. We separate what can be cleaned from what must be discarded, document the discarded items for your claim, and disinfect the rest before it comes back into the house.
Shared and high-traffic spaces
Offices, schools, places of worship, gyms, restaurants, and apartment common areas collect contamination on high-touch surfaces, and winters spent indoors keep illness moving through them. We disinfect on a schedule that suits the building, often after hours, and record what was treated and when.
How We Handle Sanitization Services in Niagara
- You call (289) 907-1745. We ask what happened and which areas are affected, and we schedule service.
- We remove debris and heavy contamination so disinfectants can reach the surface.
- We clean and disinfect surfaces with products matched to the contaminant and the pathogens involved, following label dwell times.
- We treat the air with HEPA filtration and handle deodorization at the odour source.
- We document the work for your records, your insurance, or your facility's protocol.

When You Need Sanitization, and What To Do First
- Any area touched by floodwater or sewage
- A home or workplace after a contagious illness
- Animal waste, pests, or hoarding conditions
- Persistent odours that cleaning does not remove
- A rental unit between tenants after unsanitary conditions
- Contents recovered from a flooded or contaminated space
Keep people, especially children and anyone with a weakened immune system, away from contaminated areas. Do not mix household cleaners, which can release dangerous fumes. Call (289) 907-1745 and we will plan the sanitization.
What Affects the Scope and Timeline
The scope depends on the contaminant, the size of the area, and the materials. Hard, nonporous surfaces can be cleaned and disinfected. Porous materials that absorbed floodwater or sewage are usually removed. We list the areas, methods, and products in a written scope.
A single room or office suite can often be completed in a day. Whole homes, larger facilities, and post-flood or post-sewage work take longer because they follow extraction, removal, and drying.
For businesses, we can schedule sanitization after hours and provide a record of the areas treated, the products used, and the dwell times followed. That record is useful for facility managers, landlords, and insurers who need to know the space was handled properly before people return. For homes, we explain which items were cleaned, which were discarded, and why, so you can make decisions about replacing belongings with your adjuster. Where contamination came from a flood or sewer backup, the sanitization is completed before rebuilding so new materials are not installed over untreated surfaces.
