Chimney Management

Stucco clad framed chimneys are especially vulnerable to moisture intrusion. They are frequently improperly flashed at the roof line, improperly capped, and have only stucco cladding on the shoulders, which is insufficient for keeping excessive moisture out.


Remove all stucco, sheathing, wet insulation, and damaged framing

Replace all OSB or foam board with new 1/2" plywood

Install Tyvek with cap staples

Install 10mm Keene rain screen with cap staples

Install 7/8" Weep Screed
