CSIA certified chimney service for all addresses in ZIP 29609 — north and northeast Greenville, Wade Hampton Boulevard corridor, Northgate Park, and the Lakeview area. The signature chimney challenge in this ZIP is the dual-flue chimney stack: one flue for the fireplace, one that originally served an oil furnace later converted to gas — often left open or inadequately sealed after the conversion.
ZIP 29609 north Greenville — the Wade Hampton corridor, Northgate Park, and surrounding residential streets — was built primarily in the 1960s and 1970s. Many of these homes were originally heated with oil furnaces, and the chimney stack was constructed with two separate flues inside a single masonry structure: one for the wood-burning fireplace and a second, typically smaller flue for the oil furnace exhaust. When natural gas became the standard heating fuel in Greenville through the 1980s and 1990s, most homes converted their furnaces — but the abandoned oil furnace flue often remained in place, sometimes capped at the top with a loose-fitting cover, sometimes open entirely.
Home built with dual-flue chimney: one large flue for the masonry fireplace, one smaller rectangular flue exhausting the oil-fired furnace. Both flues active and venting simultaneously. Clay tile liners original to construction.
Oil furnace replaced with high-efficiency gas unit venting through PVC direct-vent pipe to exterior — bypassing the masonry chimney entirely. The furnace flue inside the chimney stack becomes inactive. Closure treatment varies: some capped at the top, many left open.
Open or loosely capped abandoned furnace flues act as cold air conduits into the home. Bird nesting is common in uncapped rectangular flues. The active fireplace flue continues accumulating creosote while the abandoned flue remains undocumented and uninspected.
Standard chimney sweep and creosote assessment. Damper condition, smoke shelf, clay tile liner inspection from firebox to crown. Level 2 camera inspection when liner damage is suspected.
Camera inspection to document liner condition and whether the flue opening at the firebox or basement level has been properly sealed. Open abandoned flues create draft reversal and energy loss.
Uncapped rectangular oil furnace flues are common nesting sites for starlings and chimney swifts. Nest debris in an open flue creates a fire hazard if the home is ever converted back to solid fuel in that flue.
The chimney crown in 29609 covers both flue openings at the top. A single deteriorated crown affects both flues. We inspect crown condition and the cover for each individual flue opening.
