The process differs slightly depending on the type of window or door trim and the specific siding system being used, but the underlying principles remain consistent.

Flashing Installation

Flashing is a crucial component in preventing water from entering behind the siding. It acts as a secondary defense, diverting water away from vulnerable areas. Typically, flashing is installed before the siding itself. For windows and doors, this often involves L-shaped flashing pieces that are carefully positioned to overlap the window or door frame and extend up under the siding. The flashing should be securely fastened with nails or screws, ensuring a tight fit against the frame. Overlapping seams should be sealed with a high-quality sealant to prevent water leakage. A common mistake is insufficient overlap, leading to gaps where water can penetrate.

Imagine an L-shaped piece of metal flashing. The longer leg is placed under the siding, extending up and over the window frame. The shorter leg extends outwards, creating an overlap. This overlap should be at least 2 inches to ensure adequate water diversion. The flashing is then sealed to the window frame with sealant, creating a complete barrier.

Sealant Application

Sealant is used to create a watertight seal between the siding, flashing, and the window or door frame. Choose a high-quality, exterior-grade sealant that is compatible with both the siding material and the window/door frame material. Apply a generous bead of sealant along all joints and seams where the siding meets the frame and flashing.
