TL;DR
An end cap is the fitted closure that seals the open end of a gutter run, crimped and sealed onto K-style or half-round profiles in matching aluminum, steel, or copper. It is a small part with an outsized failure rate: thermal movement works the sealant loose, and the resulting drip stains siding and rots fascia right at the corner.
What it means
An end cap is the fitted closure that seals the open end of a gutter run, crimped and sealed onto K-style or half-round profiles in matching aluminum, steel, or copper. It is a small part with an outsized failure rate: thermal movement works the sealant loose, and the resulting drip stains siding and rots fascia right at the corner. Resealing with gutter-grade polyurethane sealant after cleaning the joint is a standard maintenance fix.
