If your basement took water in the July 27 or August 2 storms, you are probably somewhere between a wet vacuum and a phone call to your insurer. This article covers the order that tends to work, the local support that is open right now, and the point at which a flooded basement stops being a cleanup problem and becomes a repair problem.
What happened across Niagara
The City of St. Catharines recorded approximately 138 mm of rain in Port Dalhousie and 126 mm in Port Weller overnight on July 27 and 28, then over 100 mm across most of the city during the August 2 storm, with higher volumes in some areas (City of St. Catharines). Mayor Mat Siscoe declared a State of Emergency on August 3 (City of St. Catharines).
Niagara Falls opened a separate registry for properties affected by the August 2 flooding (City of Niagara Falls). Niagara Region is running temporary flood waste services in St. Catharines, Niagara Falls, Grimsby, Lincoln, Niagara-on-the-Lake, and Thorold, each on its own schedule (Niagara Region).
Do these four things first
- Do not enter until it is safe. Standing water near an electrical panel, outlets, or a furnace is a hazard, and water carrying sewage is a health risk. If either applies, your insurer, your municipality, and a qualified cleanup company come before anything you do yourself.
- Call your insurer. The Insurance Bureau of Canada recommends reporting as soon as possible. Ask specifically what your policy covers: overland flood coverage and sewer backup coverage are optional add-ons in Canada, not standard inclusions (Insurance Bureau of Canada).
- Document before you move anything. Photograph the water level and the damage, make a written list of what was lost, and keep every cleanup receipt. Your insurer will ask you to complete a proof of loss form, which typically has to be returned within 30 days (Insurance Bureau of Canada).
- Report the flooding to your municipality. In St. Catharines, call Citizens First at 905.688.5600 or email citizensfirst@stcatharines.ca (City of St. Catharines). In Niagara Falls, call 905-356-7521 (City of Niagara Falls). Municipal reports also help build the case for wider recovery funding.
Do not clear everything out before it is documented
Two things are pulling in opposite directions this month. Enhanced waste collection is encouraging people to get soaked material to the curb quickly, and the collection windows close soon. At the same time, the Insurance Bureau of Canada advises keeping damaged items unless they are dangerous or a health hazard, and photographing and listing everything first (Insurance Bureau of Canada).
The practical middle ground is to photograph and list before the bin, not after. Get room-wide shots that show the water line, then close shots of individual items with anything that identifies the make or model. Do that in the first hour of clearing a room and the collection deadline stops competing with the claim.
Support available right now
St. Catharines
Enhanced curbside collection for flood waste runs through August 14, with garbage placed at the curb between August 10 and 14, and no limit on large items. Tipping fees are waived at the Humberstone and Bridge Street landfills through August 15 (City of St. Catharines).
Large bins are open Monday to Friday, 9 a.m. to 4 p.m., at the St. Catharines Kiwanis Aquatics Centre and Bill Burgoyne Arena, with proof of residence. They accept drywall, insulation, flooring, carpeting, wood, concrete, roofing shingles, and plumbing pipe. Residents who need help removing water and waste from their homes can apply to the Vulnerable Assistance Registry online or by calling 905.688.5600 (City of St. Catharines).
For longer-term protection, the City's Flood Alleviation Program rebates up to 90% of eligible costs to a maximum of $5,000 for backwater valve installation and weeping tile disconnection. It applies to single-detached and semi-detached homes built before 2012 (City of St. Catharines).
Niagara Falls
The Flood Recovery Support registry covers residential owners and tenants affected by the August 2 flooding, and provides additional curbside collection of flood waste plus drop-off passes for Niagara Region waste depots at no cost. Commercial properties are not eligible.
Registration closes at 3:00 p.m. on Friday, August 7, 2026 for the August 10 collection. You can register online, by phone at 905-356-7521, in person at City Hall at 4310 Queen Street, or at the MacBain Community Centre at 7150 Montrose Road (City of Niagara Falls).
If your property is outside an eligible collection area, Niagara Region asks residents to email their address to wasteinfoline@niagararegion.ca or call the Waste Info-Line at 905-356-4141, open until 8:30 p.m. Monday to Friday through August 14 (Niagara Region).
What about provincial disaster assistance?
Disaster Recovery Assistance for Ontarians reimburses up to 90% of eligible costs to a maximum of $250,000 per application, after a $500 deductible. The part that gets missed is that the province has to activate the program for a specific area before anyone living there can apply (Government of Ontario).
As of August 6, 2026, no Niagara municipality appeared on Ontario's list of activated areas. CBC News reported that the office of the Minister of Municipal Affairs and Housing was working with the city to determine whether uninsured damage may be eligible (CBC News). Check the Ontario page directly rather than assuming the coverage is already available.
When can repairs actually start?
Not while anything is still wet. Cleanup comes first: water removal, handling of any sewage contamination, discarding materials that cannot be salvaged, and drying the structure out properly. That work belongs to your insurer's restoration contractor or a qualified cleanup company, and the City of St. Catharines points residents to Health Canada's flood cleanup guidance for safety information.
Two points from that guidance are worth knowing before you plan anything. Health Canada notes that a house and its furnishings are less likely to grow mould if they are dried within 48 hours, which is why drying is urgent even when the rebuild is not. It also treats sewage-contaminated water as a separate category requiring greater precautions, and advises that children, pregnant women, and people with respiratory problems should never handle sewage-contaminated water or materials.
Rebuilding starts once the space has been cleaned, dried, and confirmed safe. Putting finishes back over damp framing or subfloor creates a second, more expensive problem later.
What post-cleanup rebuilding usually involves
The clearest picture of the work ahead is the City's own list of accepted flood waste: drywall, insulation, flooring, carpeting, wood, and plumbing pipe. What comes out is broadly what goes back in.
For most finished basements that means new drywall and insulation on the affected walls, replacement baseboard and door trim, new flooring and transitions, repainting, and rebuilding any built-in storage, shelving, or vanity that was removed. Orestorations is a Niagara renovation contractor and this is ordinary renovation work: interior and exterior finish work of the kind shown across our completed projects. It is not emergency cleanup, water extraction, or remediation, and it is not the right call until the drying stage is done.
- Should I wait for my insurance adjuster before starting repairs?
- Talk to your insurer before repair work begins. Your claim depends on documentation, and the Insurance Bureau of Canada advises keeping damaged items unless they are dangerous or a health hazard. Emergency steps that prevent further damage are a separate matter from finished repairs.
- Is basement flooding covered by home insurance in Ontario?
- Not automatically. The Insurance Bureau of Canada notes that both overland flood coverage and sewer backup coverage are optional add-ons rather than standard inclusions, so coverage depends on the specific policy you purchased.
- How long should a flooded basement dry before rebuilding?
- There is no fixed number. It depends on how much water entered, what materials were affected, and the drying method used. The decision belongs to the cleanup professional or restoration contractor handling the drying, and it should be confirmed before any finishes are installed.
Once cleanup is complete and the space is dry and safe, call Orestorations at (437) 259-7366 to discuss post-cleanup basement repairs. If you want the visit to be useful, our guide on how to prepare for a renovation quote visit covers what to have ready.
