Chimney Repair & Masonry in Stone Mountain, GA

Chimney Repair & Masonry for Stone Mountain Homeowners

Stone Mountain's historic village holds late-1800s housing with original masonry, and some of it uses local granite rather than brick, which behaves differently: granite is far less absorbent than brick but the mortar between it still fails, and repointing stone is a more exacting job than repointing brickwork. Out through Rockbridge and Hidden Hills the housing is 1970s and 1980s subdivision with conventional flues. The village properties are the ones that need specialist attention, and they are also the ones most likely to have had a well-meaning previous repair done in the wrong material.

Late-1800s village masonry including local granite alongside 1970s-1980s subdivision flues; previous repairs in the wrong mortar are common.

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.
