Detail Side Jambs and Head — Apply Flashing Tape to Jambs and Head
Part of project
Window Installation · Step 3 of 8
In this video
To complete the flashing, apply flashing tape to the side jambs and the head (top) of the rough opening. For the side jambs, cut pieces of tape that extend from the top of the sill pan to above the head of the opening, ensuring they overlap the sill tape. For the head, apply a piece of tape that covers the entire width of the opening and extends over the side jamb tapes. This 'shingle-style' overlapping ensures that water drains downwards and outwards. Finally, use a roller to firmly press down all applied tapes, ensuring maximum adhesion and a complete seal against air and water infiltration.
FAQs
What are the most important safety precautions to take during window installation?
Always wear safety glasses and gloves to protect against debris, sharp edges, and sealant. If working above the ground floor, use appropriate ladders or scaffolding safely. Be sure to have help to lift and position the window, as they can be heavy and awkward, preventing injury or damage.
Beyond the listed tools, what other essential supplies might a beginner need for a successful and weatherproof window installation?
You will definitely need shims (wood or plastic) to properly level and plumb the window within the rough opening. A utility knife with extra blades for cutting flashing tape, and a caulking gun for applying sealant are also crucial for a clean, professional finish.
What are common mistakes beginners make when flashing and sealing a new window that could lead to leaks?
A common mistake is not applying flashing tape in the correct shingle-fashion, which can trap water. Another is using too little sealant or not ensuring a continuous bead, leaving gaps for water intrusion. Always overlap flashing layers from bottom to top and apply sealant generously to critical areas.
Is a 2-day estimated time realistic for a beginner installing a window, and what factors could extend it?
The 2-day estimate can be realistic for a beginner with a standard-sized window and a clean rough opening. However, unexpected issues like discovering rot in the rough opening, dealing with an out-of-square frame, or struggling with the weight of the window can easily extend the project time.
