What Are Retrofit Windows?
Retrofit windows are installed as part of upgrading an existing home rather than a new-construction project. The right installation approach depends on the condition of the existing openings, frames, and surrounding structure. Fortress begins with an in-home assessment so each opening can be evaluated before products and installation details are recommended.
