What is the Average Cost of Basement Waterproofing in Toronto?

The cost of basement waterproofing depends largely on whether the repair requires

exterior excavation, interior drainage systems, or crack repair.

Typical waterproofing costs in Toronto include:

• Exterior Waterproofing: $85 – $250 per linear foot

• Interior Waterproofing: $85 – $250 per linear foot

• Crack Injection Repair: $400 – $1,200 per crack

Exterior waterproofing is often the most effective long-term solution for preventing basement leaks. This process involves excavating the soil around the foundation and installing a waterproof membrane system.

Typical exterior waterproofing costs in Toronto range between:

$85 – $250 per linear foot

Factors that affect exterior waterproofing cost include:

• Depth of excavation required
• Accessibility around the foundation
• Condition of the foundation wall
• Drainage system installation requirements
• Landscaping or hardscape restoration

While exterior waterproofing requires more labour, it is often considered the most permanent solution for basement water problems.

Interior waterproofing systems are designed to capture water entering the basement and redirect it safely to a sump pump system.

Interior waterproofing typically costs between:

$85 – $250 per linear foot

Factors affecting interior waterproofing cost include:

• Size of the basement
• Amount of drainage system required
• Sump pump installation
• Existing basement conditions

Interior waterproofing is often used when exterior excavation is not possible or when additional drainage support is needed.

Foundation cracks are one of the most common sources of basement leaks. Crack injection is a professional repair method used to seal foundation cracks and stop water infiltration.

Typical crack injection repair costs in Toronto range between:

$400 – $1,200 per crack

Factors affecting crack injection pricing include:

• Length of the crack
• Wall thickness
• Accessibility of the crack location
• Water infiltration severity

When performed properly, crack injection can provide a long-lasting solution for basement leaks caused by foundation cracks.

Every basement waterproofing project is different. Several factors can influence the overall cost of the repair.

Common factors include:

• Size of the basement or foundation
• Severity of the water problem
• Foundation accessibility
• Drainage system requirements
• Landscaping restoration after excavation

A professional inspection is the best way to determine the appropriate waterproofing solution and cost estimate.

Homeowners often ask whether interior or exterior waterproofing is the better option.

Exterior waterproofing typically involves more excavation work but stops water before it enters the foundation. Interior waterproofing systems manage water inside the basement by redirecting it through drainage systems.

The most effective waterproofing solution depends on the source of the water intrusion and the condition of the foundation.

A professional inspection can determine which method will provide the best long-term results.
