Window Waterproofing

Understanding Window Systems

Windows are complex assemblies requiring careful waterproofing attention:

Wooden Windows

• Weather groove design channels wind-driven water
• Sill tray collects and disperses residual water
• Natural material requires regular maintenance
• Expansion/contraction with humidity changes

Aluminum Windows

• Relies entirely on frame waterproofing
• Drainage channels must remain clear
• Thermal breaks can be weak points
• Gasket deterioration over time

Common Window Leakage Points

1. Sill Track Drainage

   • Blocked weep holes
   • Inadequate slope
   • Debris accumulation
   • Track deformation

2. Perimeter Seals

   • Perished gaskets
   • Failed caulking
   • Frame-wall separation
   • Compression loss

3. Flashing Failures

   • Missing head flashing
   • Incorrect lap joints
   • Side flashing gaps
   • Integration issues

4. Installation Defects

   • Improper shimming
   • Out-of-plumb frames
   • Inadequate fastening
   • Missing vapor barriers

Professional Solutions

Diagnostic Process

1. Water spray testing
2. Thermal imaging
3. Air pressure testing
4. Destructive investigation (if needed)

Remedial Options

• Minor Repairs: Gasket replacement, re-caulking
