Why a Repaired Leak Keeps Coming Back

By Central Coast Building Diagnostics · July 8, 2026

The repair addressed a symptom, not the source

It’s common for a repair to seal the spot where water became visible, while the actual entry point — often elsewhere on the building — goes untouched.

Multiple contributing factors

Water intrusion is often the result of more than one factor working together: a flashing detail, a sealant gap, and a drainage issue can each contribute independently.

Repairs performed without testing

A repair based on a visual guess, without moisture testing or investigation to confirm the source, has a meaningfully higher chance of missing the actual problem.

Breaking the cycle

An investigation before the next repair identifies the actual source — or sources — so the repair addresses what’s actually happening rather than what’s assumed.
