Flush fin windows are designed for easy replacement in a stucco home. They fit inside an existing window frame without disturbing the exterior stucco or interior drywall. They can be easily trimmed onsite, and they even come with color-matched interior trim and screws. Get the basics on how they’re installed in the video below.

Here’s a summary of the steps shown in the video above.

• The contractors removed the existing sash and prepared the rough opening.
• They unpackaged the window and rested it on packaging materials to avoid scuffing the flange.
• They dry fit the window into the rough opening.
• They assessed whether or not the flange needed to be trimmed.
• They cleaned the existing window frame and the interior side of the overfit flange.
• They placed sill shims.
• They applied sealant to the existing frame leaving gaps at the sill for drainage.
• They inserted the unit and attached it to the opening.
• They checked for plumb, level, and square before fully tightening all fasteners.
• On the interior, they applied an interior air seal.
• They applied interior trim.
• They applied a bead of sealant around the exterior leaving gaps at the sill for drainage.
