Fall Foundation Maintenance Guide

Fall preparation is crucial for protecting your Toronto home’s foundation from winter’s harsh freeze-thaw cycles. October and November are your last chance to prevent costly winter damage.

Why Fall Prep is Critical

Winter Threats to Foundations

• Water freezing in cracks expands them
• Frost heave can shift foundations
• Ice dams cause water backup
• Snow melt creates hydrostatic pressure

The Freeze-Thaw Factor

Toronto experiences 40+ freeze-thaw cycles annually:

• Each cycle stresses foundation materials
• Small cracks become major problems
• Proper sealing prevents water entry
• Good drainage reduces pressure

Priority Fall Tasks

Water Management

Before the first freeze:

• Clean gutters thoroughly (leaves block winter drainage)
• Extend downspouts 6+ feet from foundation
• Check grading hasn’t settled over summer
• Clear window wells completely

Crack Sealing

Address all cracks now:

• Clean cracks with wire brush
• Apply appropriate sealant for crack size
• Allow proper curing time before freezing
• Consider professional injection for larger cracks
