Common Questions

Yes, through EPCOR's Flood Prevention Program, Edmonton homeowners can receive a subsidy of up to $800 for the installation of a backwater valve, provided the home was built before 1989 and meets specific eligibility criteria.

Edmonton's deep frost line (typically 4 to 6 feet) requires contractors to excavate significantly deeper than in warmer regions. Local estimates for full exterior excavation range from $250 to $450 per linear foot due to these soil and depth requirements.

Interior drainage systems typically cost between $70 and $150 per linear foot ($3,500 - $12,000 total), while exterior excavation and membrane systems cost $250 to $450 per linear foot ($15,000 - $45,000+ total).

Scheduling work between May and September is recommended. Winter construction in Edmonton can incur a 10-15% labor premium due to the need for ground thawing equipment and specialized material handling in sub-zero temperatures.
