Water will get into your window frame during a hurricane. That is a fact. The question is: where does it go? Weep holes give that water an escape route back outside before it damages your wall.
Different window systems use different approaches to drain water while minimizing wind-driven rain entry.
Simple round or slot openings in the frame bottom. Effective drainage but can allow wind-driven rain entry. Common on older systems and basic frames.
Weep holes with snap-in covers featuring small drainage slots. Reduces wind-driven rain while allowing water out. Most common on modern hurricane windows.
Internal baffles create a maze that water can flow through but wind cannot push past. Best performance but requires more maintenance to keep clear.
Most weep hole failures are caused by installation errors or lack of maintenance.
Installers often accidentally seal weep holes when caulking the window. Always check that all weep holes are clear after installation. Use backer rod to protect weep holes during sealing.
Paint can fill and block weep holes, especially if frames are spray painted. Mask weep holes before painting or clear them immediately after paint application.
Dirt, insect nests, and debris accumulate in weep holes over time. Annual inspection and cleaning is recommended, especially before hurricane season.
Weep hole covers can fall out or be removed during cleaning. Missing covers allow excessive wind-driven rain entry. Replace covers with correct manufacturer parts.
