Installation

Retrofit vs. Nail-Fin Window Replacement in Orange County Stucco Homes

Retrofit (flush-fin) installation leaves the original frame and stucco intact; nail-fin (full-frame) replacement removes the frame and requires re-flashing and stucco patching. The right choice depends on frame condition, water intrusion history, and whether the opening changes.
