In Canada window installation has long been a source of renovation failures. Contractors often encounter projects where windows were installed without proper flashing or sealing. This allows water to seep into the walls causing hidden rot insulation damage and drafts that make homes uncomfortable.
The Canadian climate magnifies these mistakes. Harsh winters create condensation inside poorly installed frames while heavy rains exploit any weakness in sealing. Renovators report that many homeowners discover problems only when damage is advanced. Repairing water infiltration behind windows requires removing siding insulation and drywall which adds significant cost.
Suppliers now offer advanced window systems with built in drainage channels and energy efficient glass. However proper installation remains the deciding factor. Renovators emphasize that even the best product will fail if shortcuts are taken with flashing or sealing. The trade stresses training and certification to ensure that contractors follow correct procedures.
Some professionals argue that builders often underestimate the complexity of window systems. Homeowners may pressure for faster timelines or lower costs leading to rushed work. This false economy creates more expense down the line. Renovators agree that window projects must always prioritize detail and precision.
Conclusion: window installation failures remain a costly mistake in Canadian renovations. The lesson is clear. Products must match climate conditions and installation must be meticulous. Anything less risks damage that outweighs the initial savings.
