We recently completed a parapet wall flashing repair project in Kingsway, a prestigious neighborhood in Toronto. The homeowner had been dealing with a long-standing leak from the top of the parapet wall, which had slowly caused water damage inside the property. Over time, moisture penetrated the wall and rotted out the wood structure behind the stucco, leading to soft spots and interior paint bubbling.

Upon inspection, we confirmed that the original flashing had deteriorated and was no longer diverting water away from the wall properly. Without protection, the top of the parapet had become a direct entry point for rain and snow melt, resulting in interior rot and mold risk.

Our Process: Safe Removal and Precision Repair

To resolve the issue, we first carefully removed the wall cladding and exposed the full extent of the damage. All rotted wood was removed and replaced with new exterior-grade plywood sheathing, ensuring structural strength. Next, we applied a durable vapor barrier, fully adhered and sealed at all seams to prevent future moisture entry.

For long-term protection, we fabricated and installed custom metal flashing that was designed specifically for the wall’s measurements. The flashing extended across the top of the parapet and down both faces, with angled returns to divert water away from the structure. We sealed all joints, overlaps, and transition areas to ensure complete water tightness.
