Chimney Liner & Cap Installation for Dunwoody Homeowners

Dunwoody's housing is dominated by two-storey building from the 1970s and 1980s, and the height changes the physics. A tall flue in a well-sealed house frequently has a draft problem rather than a dirt problem: the chimney is competing with kitchen and bathroom extraction in a house tight enough that air cannot easily replace what is being drawn out, and the fireplace loses. Homeowners read that as a dirty chimney and book a sweep, which sometimes helps and sometimes does not touch the real cause. We would rather diagnose it properly than clean a flue that was not the problem.

Tall two-storey 1970s-1980s flues in relatively tight houses; negative pressure and draft competition are as common as creosote.

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.
