South County crown repairs in Chula Vista and Bonita are often the difference between a passable home inspection and a failed one.
Crown coat or full rebuild?
Crown coat works on crowns with hairline cracks and intact structure. It is a flexible elastomeric layer that bridges small cracks and waterproofs the surface for 10+ years. Full rebuild is needed when the crown has structural cracks (wider than a credit card), is missing chunks, or was poured wrong from the start with no overhang.
Why does my crown keep cracking?
Two common causes. First, the crown was poured directly on the flue tile with no bond break, when the tile expands during a fire, it cracks the crown. Second, the crown was poured flush to the brick with no overhang, so water sits and freezes in the masonry below. We fix both during a rebuild.
