Installation Techniques
Superior V4 Shield Installation
We replace only the glass, not the whole frame. Our modern method avoids bulky retrofits or frame tear-outs by custom-building V4 Shield™ glass to fit your original frame. It's clean, efficient, and non-disruptive.
We focus on replacing the glass, not the whole window. That means lower costs and faster installs.
You should know about the “old” ways
USE CAUTION
Retro-fit into your existing vinyl windows
Retrofit vinyl windows were made for thin aluminum frames. Installing them will causes major glass loss, egress issues, and costly interior conflicts.
Stucco breakout
Stucco is chipped out to access and peel back building paper for window removal, aiming to preserve waterproofing. However, this process often tears the paper, risking future water intrusion.
Patch and blend
After window installation, stucco is patched in layers—scratch, brown, then finish coat—but blending is difficult. The patched area often stands out, drawing unwanted attention to the new window
