Waterproofing Cost Factors

Factors that Influence Cost of Basement Waterproofing in Toronto

Basement waterproofing cost in Toronto in 2023 is impacted by a number of factors like the type of waterproofing, materials selected for the project, the extent of foundation damage, and other factors. 

  1. Size of the Area - the larger the area that needs to be waterproofed, the more expensive the project will be. This is because more materials and labor hours will be required.

  2. Type of Waterproofing - different types of waterproofing methods have different costs. For example, liquid waterproofing might be less expensive than installing a waterproof barrier.

  3. Materials Used - the cost of the waterproofing materials themselves can greatly impact the overall cost of the project. Higher-quality materials often cost more, but they may provide better protection and last longer.

  4. Condition of the Area - if the area that needs to be waterproofed is in poor condition, extra work may be needed to prepare it. This could involve removing old materials, fixing cracks, or dealing with mold or mildew issues.

  5. Accessibility - if the area to be waterproofed is hard to access, it may take more time and therefore, result in higher labor costs.

  6. Equipment Needed - some waterproofing jobs may require specialized equipment. The cost to rent or buy this equipment can impact the overall cost of the project. 

  7. Maintenance and Repair Costs - depending on the waterproofing system installed, there may be ongoing maintenance or repair costs to keep the system functioning correctly.
