Why Louisiana Weather Exposes Weak Installation

When the frame is out of square, flashing is incomplete, or sealant is used where real waterproofing should be doing the job, water finds the weak spot.

Heat creates another problem. Frames move, caulk ages, and any missed step in the installation gets magnified once the sun bakes the opening day after day.

This matters even more in older houses and in homes that have been remodeled more than once, because rough openings are not always perfectly consistent.

What Proper Installation Actually Does

Good installation is not just placing a unit in the opening and fastening it down.

A correct install starts with fit. The opening needs to be checked for square, plumb, and level, then sealed and flashed so water sheds outward instead of settling in the wall cavity.

Moisture between the panes, which usually means the insulated glass seal has failed. Sashes that stick, bind, or refuse to latch cleanly. Open gaps, crooked trim, or caulk pulling loose from the frame.

The frame, the surrounding wall, and the condition of the seal usually tell the story.

Materials, Glass, And Storm Considerations
