CSIA certified chimney inspection for West Greenville's 1950s–1970s masonry. This corridor's primary inspection finding is moisture-driven deterioration — cracked crowns, spalling brick, failed flashing, and liner joint failure caused by decades of water cycling through masonry that was never treated or waterproofed. Inspection identifies every entry point and documents the current state of each affected component.
Water damage in masonry chimneys does not happen all at once — it progresses through predictable stages. Inspection identifies which stage has been reached so the appropriate repair scope can be determined.
Portland cement crown develops hairline cracks. Water enters with each rain event.
Water travels down the interior, soaking clay tile mortar joints. Joints soften and fail.
Absorbed water freezes and expands in cool months. Brick face pops off in flakes or chunks.
Mortar at the roof-chimney junction deteriorates. Water enters at the roofline and wets framing.
Long-term saturation erodes mortar between bricks. Chimney structure becomes unstable.
White mineral salt deposits on exterior brick — a clear indicator that water is moving through the masonry and evaporating at the surface.
Brick faces that have cracked, popped, or flaked off. Visible from the ground on West Greenville masonry that has experienced freeze-thaw cycling.
Water stains on the ceiling or adjacent wall during or after rain events. Indicates flashing failure at the roof-chimney junction.
A persistent musty or damp smell from the fireplace opening when it has not been used. Indicates water is standing inside the flue or on the smoke shelf.
A crack or gap visible in the mortar crown at the chimney top. Even hairline cracks allow water entry that accelerates deterioration of the liner below.
Orange-brown rust streaks running down from a corroded metal cap or damper. Indicates the cap or damper is rusted through and no longer sealing the flue.
