My Basement Is Flooding, Who Do I Call To Clean Flood Water And Dry It Near Toronto?

By: AGC Pro Construction

Few homeowner moments trigger instant panic like stepping into your basement and hearing that unmistakable splash.

If your basement is flooding, the most important thing to remember is this: time matters.

The first 24 to 48 hours can determine whether you are dealing with a simple drying job or a full-scale mould remediation and reconstruction project.

Let’s walk through exactly who to call, what to do immediately, and how to protect your home properly.

Why Basements Flood So Often In Canada

Basement flooding is not rare in Canada. In fact, flooding is considered the most costly natural disaster in the country. According to the Insurance Bureau of Canada, severe weather events have caused billions in insured losses in recent years, with water damage leading the claims category.

In 2022 alone, insured catastrophic losses exceeded $3.1 billion, much of it related to water and flooding events.

Common causes include:

  • Rapid spring snowmelt overwhelming drainage systems
  • Intense rainfall exceeding municipal sewer capacity
  • Sewer backups in older neighbourhoods
  • Sump pump failures during storms or power outages
  • Foundation cracks and poor exterior grading
  • Frozen ground preventing proper water absorption

Understanding the cause matters, because it determines who you call first.

Who Should You Call When Your Basement Is Flooding?

If there is standing water, your first call should be to a 24/7 emergency water damage restoration company like AGC Pro Construction. These professionals specialize in flood extraction and structural drying using commercial equipment.

If the flooding is still active, you may also need:

  • A plumber (for burst pipes or sewer backup)
  • An electrician (if water is near your electrical panel or outlets)
  • Your insurance company to open a claim
  • Your municipality if the issue appears related to sewer backup programs

The key is acting immediately. Waiting even 12 to 24 hours significantly increases the risk of mould growth.

Why DIY Flood Cleanup Is Risky

It is tempting to grab a shop vacuum and some fans. Unfortunately, most household equipment cannot properly dry structural materials.

Professional water damage falls into three categories:

Category 1: Clean water (e.g., supply line leak)
Category 2: Grey water (appliance discharge)
Category 3: Black water (sewage, ground water contamination)

Category 2 and 3 water carry bacteria and contaminants. According to Health Canada, indoor mould and microbial growth can begin developing within 24 to 48 hours in damp conditions.

Household fans do not create the airflow and dehumidification required to dry inside walls, under flooring, or inside insulation.

What A Professional Flood Cleanup Company Does

When you call a certified restoration company, here is what typically happens:

Immediate Water Extraction
Industrial pumps and truck-mounted systems remove standing water quickly.

Moisture Mapping
Technicians use moisture metres and thermal imaging to detect hidden water in walls and subfloors.

Controlled Drying Setup
Commercial air movers and dehumidifiers are strategically placed to create evaporation and controlled humidity reduction.

Daily Monitoring
Moisture readings are tracked to ensure materials return to dry standards.

Sanitization And Antimicrobial Application
This helps reduce microbial growth in contaminated water situations.

Selective Demolition
If drywall, insulation, or flooring cannot be saved, it is removed to prevent mould spread.

Insurance Documentation
Professional reports and drying logs support your claim.

Drying typically takes between 3 to 7 days, depending on severity.

What To Do In The First 60 Minutes

If safe to do so:

Turn Off Power To The Affected Area
Water and electricity are a dangerous combination.

Stop The Water Source
If it is a burst pipe, shut off your main valve.

Avoid Contact With Contaminated Water
Wear gloves and waterproof boots.

Move Valuables And Electronics
Lift items off the floor and relocate them to dry areas.

Document Everything
Take photos and videos before cleanup begins.

Call A Restoration Company Like AGC Pro Immediately
Fast response dramatically reduces damage.

How Much Does Basement Flood Cleanup Cost In Canada?

Costs vary depending on:

  • Size of the affected area
  • Category of water
  • Material removal requirements
  • Length of drying time

Minor clean water incidents may cost a few thousand dollars. Larger sewer backups with material removal and reconstruction can exceed $10,000–$30,000 or more.

Insurance coverage depends on your policy. Many Canadian homeowners require a sewer backup endorsement for coverage. Overland flood coverage is typically an optional add-on.

Will Insurance Cover It?

It depends on the cause.

Burst pipes are usually covered.
Sewer backups require specific endorsements.
Overland flooding may require separate coverage.

The Insurance Bureau of Canada reports that sewer backup claims are one of the most common home insurance claims nationwide.

Always review your policy before disaster strikes.

Health Risks Of Flooded Basements

Flooded basements create ideal conditions for mould. Health Canada advises that exposure to indoor mould may cause respiratory irritation, coughing, and aggravation of asthma.

Standing water can also contain bacteria, especially in sewer-related events.

A musty smell after drying often indicates hidden moisture behind walls.

Signs You Need Professional Structural Drying

You may need professional help if you notice:

  • Warped or swollen baseboards
  • Soft drywall
  • Persistent damp odours
  • Buckling laminate flooring
  • Wet insulation behind walls
  • Reappearing mould spots

If materials are not dried to proper moisture content, problems can resurface months later.

How To Prevent Future Basement Flooding

Install A Backwater Valve
Prevents sewage from flowing back into your home.

Upgrade Your Sump Pump
Add a battery backup system.

Improve Exterior Grading
Ensure water flows away from your foundation.

Extend Downspouts
Move discharge at least 6 feet away from the house.

Seal Foundation Cracks
Professional epoxy injections can help.

Schedule Annual Inspections
Proactive maintenance saves thousands.

Frequently Asked Questions

Who Do I Call First If My Basement Is Flooding?
Call a 24/7 water damage restoration company immediately. If water is still actively entering, contact a plumber as well.

How Quickly Does Mould Start Growing After A Flood?
Mould can begin developing within 24 to 48 hours in damp conditions, especially in porous materials like drywall and insulation.

Can I Stay In My House During Basement Drying?
In most cases yes, unless contamination is severe or electrical hazards exist. Restoration companies can advise based on water category.

Is Rainwater In My Basement Considered Clean Water?
Not necessarily. Once rainwater enters a basement, it can mix with soil and contaminants, potentially classifying it as Category 2 or 3 water.

How Long Does It Take To Fully Dry A Basement?

Will My Insurance Premium Go Up After A Claim?
It depends on your provider and claim history. Some policies include claim forgiveness programs.

Should I Remove Wet Carpet Myself?
Wet carpet from contaminated water should be handled by professionals to avoid exposure to bacteria and mould spores.

Do Fans And Dehumidifiers From A Hardware Store Work?
They can assist minor dampness, but they do not replace commercial drying equipment designed for structural materials.

What If My Sump Pump Failed During A Storm?
You may still be covered if you have sewer backup or overland flood endorsements. Documentation is essential.

Can A Basement Flood Cause Long-Term Structural Damage?
Yes, prolonged moisture can weaken wood framing, damage drywall, and deteriorate insulation if not dried properly.
