Chimney Repair & Masonry in Marietta, GA

Chimney Repair & Masonry for Marietta Homeowners

Marietta covers more chimney history than anywhere else we serve. Around the Square and Whitlock Avenue there are genuinely antebellum and Victorian homes with hand-laid brick flues and lime mortar that predates Portland cement, and they need to be treated accordingly — a hard modern mortar mix on that brick will destroy it. Push east into the 1980s and 1990s East Cobb subdivisions and the picture changes completely: prefabricated fireplaces, framed chases, metal chase covers. The two jobs share a name and almost nothing else, and the mistake is applying one approach to the other.

Almost every chimney failure in this part of Georgia is a water story. The crown — the concrete slab across the top — is the stack's roof, and when it cracks, rain runs straight into the masonry core instead of off it. From there the freeze-thaw cycles we get in January do the rest: water in the brick expands, and the face of the brick shears off in flakes. That is spalling, and once it starts it accelerates, because every flake exposes more absorbent surface. A crown recast while the cracks are hairline is a routine job. The same chimney left four winters is a rebuild from the roofline up, at several times the cost.
