INSTALLATION OF WINDOWS
The Learning Center
2. What are the most critical details to consider during installation?
< back to list of questions about installation
You should make sure the exterior and the interior of your home are protected in some way to prevent damage. Once your old window is
removed, the opening should be inspected and any damaged materials or rotted wood should be replaced. Make sure that the installer
does not simply cover up any problems. When it comes to windows and doors, it’s critical to keep the unit level, plumb and square. This
means that the window or door must be uniform horizontally, vertically, and diagonally within the opening.
Shims are crucial to the performance of the window or door installation. Shimming under the sill of a window keeps it up off the rough
opening, allowing incidental water to drain to the exterior. Shimming around a window or door helps to hold it uniformly in the opening,
plumb, level, and square. Once the window or door is fastened and flashed, the installer will insulate the interior between the window or
door and the old opening with fiberglass or a bead of low-expansion polyurethane foam sealant. Fiberglass insulation helps prevent
bowing or warping of windows and doors.
Custom finish work, including proper caulking, is completed on both the interior and exterior. A wide variety of options are available to meet
the needs of the customer. This is one area that is typically taken for granted, and where the quality of the finished product can vary
greatly. Be clear on the finish details.
The job site, including the new windows and doors, should be thoroughly cleaned both inside and outside. The old windows, doors, and
miscellaneous materials should be removed. You should make a final review with the installer to assure that everything that was agreed
upon is done to your satisfaction.
