Chimney Liner & Cap Installation in Marietta, GA

Chimney Liner & Cap Installation 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.

The liner is what stands between the fire and the timber frame of your house. Plenty of intown Atlanta bungalows were built with no liner at all — just brick — and plenty more still carry the original clay tiles, which crack when they are heated unevenly and open a path for heat and flue gases into the surrounding structure. A stainless liner sized to the appliance solves that permanently, and it usually improves the draft as a side effect, because most old flues are far larger than what a modern insert or gas appliance actually wants. The cap is the cheaper end of the same principle: an open flue is an invitation to rain, leaves and every nesting bird in the neighbourhood.
