Window Style Considerations for High-wind Areas

How to match window type to Gulf conditions

Casements seal tighter than many double-hungs, which helps in wind-driven rain, while awning windows for ventilation in humid Mandeville LA climate can sit open under light showers without collecting water inside.

Ensuring Proper Window Installation

The best glass will fail if the install is wrong

Cost Considerations for Window Replacement
