The Caulking Process
Now that you’ve prepared the area, it’s time to start caulking. Here’s a step-by-step guide:
- Choose the Right Caulk: Select a high-quality, exterior-grade caulk that’s suitable for your window type (vinyl, aluminum, or wood).

- Apply the Caulk: Hold the caulk gun at a 45-degree angle and apply the caulk bead in a continuous motion.

Common Mistakes to Avoid
- Don’t over-cault the bead, as this can lead to a uneven appearance.
