    Common Window Defects Found During Inspection

    A window can have multiple joints, hinges, rails and fragile components that must all work perfectly. This means there are many points in the manufacturing process that could cause defects and compromise the window’s performance. Here are the most common issues found during home inspections.

    Window installation mistakes

    Condensation Inside Multi-Pane Glass

    Multi-pane glass is supposed to be airtight in order to provide good insulation. However, defects during the manufacturing process can create small gaps where air and moisture can seep inside. When the temperature is right, water vapor in the air condenses, forming droplets of water on the surface or fog. If left unchecked, the condensation can also lead to mold or fungus growth as well as moisture damage to the frame.

    Clogged Weep Holes

    Weep holes are small gaps along the bottom of the window designed to let moisture escape. If the window is defective, the weep holes could either be too small and get easily clogged by dirt, or simply be inefficient at allowing water to leak out. High-quality window installation companies make sure that a window’s weep holes are appropriately sized to allow proper drainage and prevent moisture-related issues.

    Sagging Sashes

    A common issue with casement windows, sagging sashes are often caused by loose hinges or weak frame material, with the weight of the sashes pulling down on the window and causing it to go out of alignment. A well-made window will have properly secured hinges and sashes to keep it from sagging throughout its expected lifespan.
