Why chimney rebuilds matters here in Studio City
Valley heat cycles work hardest on mortar that was mixed or tooled poorly to begin with, which is why the quality of the original repair matters as much as its timing. A properly repointed joint outlasts a rushed one regardless of how many summers follow. A typical visit covers partial rebuild (above roofline), full chimney reconstruction, and earthquake damage repair and retrofit, so the scope reflects what's actually happening at the chimney rather than a number picked out of the air.
