Ontario winters are hard on buildings. Freeze-thaw cycles, ice, wind-driven snow and road salt all attack the building envelope. A little preparation in the fall prevents expensive emergencies in January.
Seal the envelope before the freeze
Water that gets in before a freeze causes the most damage. Inspect and re-seal failed caulking around windows, doors, panels and control joints while temperatures still allow proper adhesion. This is the single highest-value winter-prep task.
Address cracks and spalling now
Any open crack in stucco, masonry or concrete is a place for water to enter and freeze. Injecting cracks and patching spalled concrete before winter stops the freeze-thaw cycle from widening the damage over the season.
Check flashing, drainage and downspouts
Make sure metal flashing is intact and directing water away from the wall, and that drains and downspouts are clear. Ice damming and pooling water find every weakness in a roofline or parapet.
Protect balconies and parking structures
These take the worst of the salt and freeze-thaw exposure. A sound waterproofing membrane and traffic coating protect the structural slab and the steel within it through the harshest months.
Don’t forget glazing and weather seals
Foggy or failed sealed units and worn weather-stripping leak heat all winter. Replacing them improves comfort and cuts heating costs immediately.
A fall inspection pays for itself
A short pre-winter assessment identifies the weak points while there’s still time to fix them in good conditions. Our team can walk your property, prioritize what matters, and get it sealed up before the first hard freeze.
