Apply Silicone Sealant to Window Frame Joints

What happens here

Ensure the window frame and surrounding siding are clean and dry, as with siding gaps. Holding the caulk gun at a 45-degree angle, apply the silicone sealant to the vertical joint where the window frame meets the siding. Maintain steady pressure and a consistent speed to create a uniform bead. Continue this process for all vertical and horizontal joints around the window frame where sealing is necessary. For optimal results, within 5-10 minutes of application, use a caulk tool or a gloved finger lightly dipped in soapy water to smooth the bead, pressing the sealant firmly into the joint and removing any excess for a clean, professional finish. This step is crucial for preventing water from penetrating behind the window casing and into the wall structure.

Goal: Carefully apply a continuous bead of silicone sealant along vertical and horizontal window frame joints, ensuring thorough coverage and a watertight seal to prevent moisture intrusion. The video shows the application of caulk along the vertical side of a window frame.
