Interior Waterproofing ($150-200/linear foot)
Interior systems are typically less expensive because they don't require excavation. However, they manage water after it enters rather than preventing entry.
What's included:
- Drainage system installation
- Sump pump and pit
- Vapor barrier application
- Floor restoration
- Dehumidification system
Exterior Waterproofing ($250-400/linear foot)
Exterior systems cost more due to excavation requirements but provide comprehensive protection by stopping water before it reaches your foundation.
What's included:
- Complete excavation around foundation
- Foundation cleaning and preparation
- Waterproof membrane application
- Drainage system installation
- Backfill and landscaping restoration
Major Cost Factors
1. Foundation Perimeter Length
Most waterproofing is priced per linear foot of foundation. A typical Toronto home (30x40 feet) has 140 linear feet of foundation perimeter.
2. Excavation Depth and Accessibility
Deeper excavation costs more. Toronto's clay soil and potential utilities increase excavation complexity and cost.
3. Existing Drainage Conditions
Homes without existing drainage systems require more extensive work. Old or failed systems need complete replacement.
4. Landscaping and Hardscaping
Decks, patios, mature trees, and expensive landscaping increase costs for exterior waterproofing due to removal and restoration requirements.
5. Basement Finishing Level
Finished basements require careful removal and restoration of flooring, walls, and fixtures, adding $3,000-8,000 to interior projects.
6. Soil Conditions
Toronto's clay soil can be challenging to excavate and may require special handling, increasing labor costs by 15-25%.
