Seal Exterior Hose Bib with Silicone Caulk

What happens here

As a final step, apply 100% silicone caulk around the exterior perimeter of the newly installed hose bib where it meets the brick wall. This will create a watertight seal, preventing moisture intrusion into the wall cavity, which is crucial for maintaining the integrity of the home's structure and preventing potential damage from frost.

Goal: Prevent water intrusion into the wall cavity by sealing the exterior of the hose bib.
