Water damage restoration
Stop the spread, extract water, and dry structures before bacteria and mould take hold.
Water damage guide →Greater Toronto Area · 24/7 emergency restoration
Guardian Emergency Response is a 24/7 emergency restoration company serving the Greater Toronto Area for water damage, fire and smoke cleanup, mould remediation, and insurance-related disaster response. We work with homeowners, condo corporations, property managers, and commercial buildings in Toronto, Vaughan, North York, Markham, Richmond Hill, Newmarket, Stouffville, and across the GTA. The job is to stop secondary damage the same day the loss happens — extract water, contain soot, document moisture — then hand insurers a clear file.
When disaster hits your home or business, the first hours matter. We stabilize the site fast, dry and remediate properly, and keep clear records for your claim.
Active fire or anyone in danger? Call 911 first. We handle mitigation once the site is safe.
Services
Guardian handles the emergency mitigation after a leak, flood, fire, or moisture event — water extraction and structural drying, fire and smoke cleanup, mould work after unresolved wet materials, and the photos and moisture readings adjusters typically ask for.
We are a restoration company, not a plumber-only shop and not a general contractor that starts weeks later. A plumber stops the pipe. Guardian removes the water that already entered floors, walls, and contents. Reconstruction can follow once the building is dry and documented.
Stop the spread, extract water, and dry structures before bacteria and mould take hold.

Mould guide →When to call
Call Guardian Emergency Response if water is still spreading, a ceiling is wet and sagging, sewage or grey water has entered the unit, smoke or soot is on surfaces after a fire, or a leak sat wet long enough that mould is likely.
Standing water, a sagging ceiling, or water moving into wall cavities — do not wait overnight.
Sewage or grey water in the unit, soot after a fire, or materials that sat wet long enough for mould — call for mitigation.
Call your insurer as soon as it is safe so a claim number exists. In Ontario, many policies expect reasonable steps to prevent further damage. Mitigation and the insurance call can happen in the same hour.
Do not wait overnight if standing water is present, water is in wall cavities, or a stack flood is moving into other units. Not sure who to dial first? Read who to call for a Toronto basement flood.
First day
A typical first day on a water loss:
Drying continues after that first visit. “It feels dry” is not the standard. Equipment stays until readings support removal. Skipping extraction overnight is how a one-room leak becomes a mould job. Moisture meters decide when equipment comes out.
Claims & clients
Many homeowner and condo policies cover sudden water damage and the reasonable cost to dry the structure. Gradual leaks, poor maintenance, and some sewer backups may be limited or excluded. Coverage is a policy question. Mitigation is a building question.
Guardian documents the scene so the file is usable: source if known, path of water, rooms affected, moisture readings, equipment on site, and what was removed versus dried. We do not decide liability between a unit owner and a condo corporation. We give both sides a clear record.
Homeowners after burst pipes, appliance failures, and basement floods. Condo boards and property managers after stack floods and suite leaks. Commercial buildings after system failures. Insurers and adjusters who need a documented mitigation file.
Guardian Emergency Response is a local GTA operator, not a national call centre that hands the job to an unknown sub. Ask who actually arrives, whether they document moisture, and whether they will speak to the adjuster.

FAQ
Direct answers first — optimized for featured snippets and AI overviews.
Call the restoration company if water is still spreading or a ceiling is wet. Call the insurer as soon as it is safe so a claim number exists. Ontario policies often require reasonable steps to prevent further damage. Guardian can mobilize and document the scene in the same window.
Extract standing water, set drying equipment, isolate wet rooms, protect contents, and record moisture readings and photos. Drying continues after the first visit. The first night is about stopping secondary damage, not finishing the rebuild.
Often yes, when the loss is sudden and accidental. Gradual leaks and some sewer backups may be limited. Guardian documents what was necessary; the insurer decides coverage under the policy. See also our guide on sewer backup coverage in Ontario.
There is no honest single number. After extraction, a finished basement often needs several days of commercial drying. Contents, insulation, outdoor humidity, and how long it sat wet change the clock. Moisture meters decide when equipment comes out.
The plumber stops the leak. Guardian removes the water that already entered the structure and dries it to a documented standard. You usually need both. For the full call order, see who to call if your basement is flooding.
The corporation typically covers common elements and often the standard unit; owners cover upgrades and contents depending on the declaration. Deductible chargebacks are common where a by-law exists. After a stack flood, both sides may file claims. Guardian mitigates and documents — we do not assign fault. Details: who pays after condo water damage.
Yes. After the fire service leaves, we contain soot, protect unaffected areas, address HVAC spread where it is part of the scope, and clean affected surfaces and contents before reconstruction starts. More: first 48 hours after fire damage.
Yes, when mould follows a water loss or unresolved moisture. The sequence is find the moisture, dry or remove wet materials, then clean under containment. We do not treat mould as a paint problem.
In most Ontario home claims you can choose your own restoration company. Insurers may suggest preferred vendors; mandatory use is not the usual rule — confirm with your broker. Mitigate promptly and keep documentation clear.
Photograph first. Do not discard major items until they are documented unless they are a clear safety or contamination hazard (for example Category 3 sewage-soaked porous materials your restoration team flags for removal). Keep a simple inventory of what leaves the site.
Sometimes, when mould is a direct result of a covered sudden water loss and you mitigated reasonably. Gradual moisture, long-term leaks, and maintenance issues are often limited or excluded. Confirm with your broker — this is general information, not insurance advice.
It varies — there is no honest fixed price. Cost depends on water category (clean vs sewage), square footage affected, how long materials sat wet, finishes (carpet, hardwood, insulated walls), and whether contents need pack-out. Guardian sets the scope after moisture mapping; be wary of anyone quoting a firm total before they have seen the loss.
Category 3 is grossly contaminated water — including sewage and many storm backups through floor drains. It changes PPE, disposal, and what can be saved. Porous materials are often removed rather than dried in place. More: sewage vs clean water.
Sometimes. Clean water on hard surfaces, caught early, often dries in place. Carpet pad, insulation, and drywall that wicked Category 2/3 water or sat wet for days are frequently removed. Moisture readings and water category decide — not appearance alone.
Often yes if living floors are dry, utilities are safe, and there is no sewage contamination in occupied areas. Leave if there is electrical risk, Category 3 water in living space, or structural concern. Equipment is noisy; plan for that.
Building defects and maintenance failures generally sit with the landlord under the Residential Tenancies Act (s.20). Tenant belongings usually sit on tenant insurance. Notify the landlord in writing the same day. Guide: tenant vs landlord water damage.
Call 647-278-2494 any time. Give the address, what failed (pipe, appliance, fire, unknown stain), whether water is still moving, and whether an insurer is already involved. If it is safe to do so, photograph the rooms before moving contents.
