Balcony & Window Leak Inspection
Detailed inspection of balconies, parapets, windows, and flashing to identify leak sources and prevent water damage.
Protect Your Building Envelope
Balconies and windows are common entry points for water infiltration in BC buildings. Our specialized inspection services examine these critical areas to identify current leaks and potential vulnerabilities before they cause extensive damage to your property.
We use advanced moisture detection equipment, thermal imaging, and visual inspection techniques to assess balcony membranes, window installations, flashing details, and drainage systems comprehensively.

What We Inspect
Balcony Membranes
Assessment of waterproof membrane condition, including cracks, bubbling, deterioration, and proper drainage slope.
Window Installation
Examination of window flashing, sealants, and installation details to ensure proper water management.
Parapet Walls
Inspection of parapet wall caps, flashing, and transitions to identify potential water entry points.
Drainage Systems
Evaluation of drains, scuppers, and overflow systems to ensure proper water evacuation.
Common Issues We Find
Failed Sealants
Deteriorated or missing caulking around windows and balcony penetrations allowing water entry.
Improper Flashing
Incorrectly installed or damaged flashing failing to direct water away from vulnerable areas.
Membrane Damage
Punctures, tears, or deterioration in balcony waterproof membranes compromising water resistance.
Poor Drainage
Inadequate slope, clogged drains, or missing overflow protection causing water pooling.
Window Back-Panning
Missing or improperly installed back-panning beneath windows allowing water to bypass flashings.
Structural Cracks
Cracks in balcony slabs or window surrounds creating pathways for water infiltration.
