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.
