Prevent Window Seal Blowouts in High Winds

Cost Savings

Checklist Tasks

• Inspect glazing beads for gaps to stop wind-driven rain intrusion.
• Replace brittle caulking with flexible sealant to allow movement.
• Test window locks for full engagement to reduce frame flex and seal strain.
• Examine weep holes for blockages to prevent water buildup behind seals.
• Apply silicone at sash-to-frame joints where air leaks are found.
• Tighten or replace hardware screws to prevent frame racking in high winds.
• Install storm panels or film on vulnerable windows to reduce pressure on seals.
• Check for condensation between panes to identify failed seals needing repair.
• Trace air leaks with a smoke pencil to pinpoint infiltration paths.
• Reinforce window stops with weatherstripping to cushion impacts.
• Document window manufacturer and install dates for warranty tracking.
• Schedule a professional pressure test if multiple windows show seal stress.
