🧱 1. Stucco is Cut Back During Window Removal
-
Most homes with stucco have windows that are embedded into the stucco exterior.
-
To properly remove the old window and install the new one with a good seal, installers must cut into or break the stucco around the window perimeter.
-
This exposes the flashing, waterproof barrier, and framing, which are critical to re-seal properly after the new window goes in.
🛠 2. Proper Waterproofing Requires Stucco Repair
-
After the new window is installed, the flashing (metal or rubberized waterproof material) needs to be layered in correctly to prevent leaks.
-
The stucco around the window then needs to be patched or redone to match the original finish, protect the home, and ensure the seal is watertight.
🔍 3. Aesthetics: Seamless Finish
-
Cutting into stucco creates visible edges.
-
Without patching and matching, the area around your new windows could look sloppy or mismatched.
-
Skilled stucco repair ensures the texture and paint match the rest of your home’s exterior.
🧰 4. Full-Frame vs. Retrofit Affects Stucco Needs
-
Full-frame window replacement: Almost always requires stucco work because the entire window, frame, and surrounding materials are replaced.
-
Retrofit (insert) windows: May not need stucco work if installed within the existing frame, but this method isn’t always possible or ideal (especially in older or damaged frames).
Summary:
✅ Stucco work ensures:
-
Proper waterproofing
-
Structural integrity
-
Visual consistency
-
Long-term durability of your new windows
