Retrofit Installation
-
1. Measurement
Since each window is custom manufactured for the specific opening, the crucial first step is to precisely measure the opening into which the retrofit window will be installed. A window is then ordered to exact specification, allowing for clearances recommended by the manufacturer.
-
2. Opening Preparation
The old sashes are removed, leaving the existing frame intact. All obstructions, such as loose materials and old caulk, are cleared away. The new window is tried in the opening to make sure it fits properly and that no other adjustments to the space are necessary.
-
3. Precaulk
A liberal and continuous bead of elastomeric sealant is applied either on the fin or on the mounting surface around the entire perimeter.
-
4. Installation
The window is installed and shimmed. A level is used to ensure that the window is level, plumb, and square. Once proper adjustments have been made, the window is anchored with corrosion-resistant screws at predetermined locations along the window frame, per manufacturer's instructions. The window is then checked for smooth operation and locking.
-
5. Insulatin
The gap between the retrofit frame and the rough opening is filled with non-expanding foam.
-
6. Trim
Flat trim is applied on the interior, covering the gap between the new window frame and the rough opening.
Optional: Optional jamb and casing is installed for an enhanced, custom look.
-
7. Exterior Caulk
The entire perimeter of the window is weather sealed using elastomeric caulk.
-
8. Interior Caulk
To create a uniform look, the perimeter of the inside of the window is caulked.
-
9. Cleanup
All window stickers and decals are removed, windows are cleaned, and work area is vacuumed.
-
10. Final Walk-Through
