What happens here

This instructional project demonstrates why horizontal siding butt joints should *not* be caulked. It highlights how the natural expansion and contraction of siding leads to the failure of caulk applied to these joints, resulting in unsightly cracks and compromising the integrity of the sealant. The core lesson is to allow these joints to breathe for proper long-term performance and appearance.
