Freeze Protection

Freeze protection for masonry is essential in Ontario where temperatures plummet below -20°C, causing water trapped in bricks and mortar to expand with devastating force that shatters even solid stone. This protective strategy involves multiple approaches: proper drainage to minimize water exposure, breathable sealers that repel liquid water while allowing vapor escape, and quality repointing that eliminates cracks where water collects. Critical areas needing protection include horizontal surfaces like window sills and copings, chimneys exposed to weather extremes, and ground-level masonry subject to splash-back and salt exposure. Winter masonry work requires special additives, heating, and protection to prevent mortar freeze damage before curing. Existing damage from freeze-thaw cycles appears as spalling, pop-outs, and deteriorating mortar requiring prompt repair before winter. Fix My Brick implements comprehensive freeze protection strategies tailored to your building's exposure, ensuring masonry survives Ontario winters for decades without costly damage.
