Rotten Wood Exterior Chimney Replacement

Rotten Wood Chimney Replacement — Complete Structural Restoration

Wood-framed chimney chases are common in Florida homes, especially those built since the 1970s. While cost-effective to build, these structures are vulnerable to water infiltration that rots the framing from the inside out. By the time external signs appear — soft siding, stucco cracks, visible rot — the internal damage is often extensive and the chimney is structurally compromised.

How Wood Chimneys Rot

Water enters through: failed chase covers from above, deteriorated flashing where the chase meets the roof, cracked stucco or damaged siding, missing kick-out flashing at the base, and condensation from uninsulated fireplace pipes. Once moisture reaches the framing, fungal growth begins and progresses rapidly in Florida's humid climate.

Complete Replacement Process

We remove all rotted framing and exterior materials down to sound structure, then rebuild using pressure-treated lumber rated for structural applications. New moisture barriers, including housewrap and self-adhering flashing membranes, protect the new framing from future water exposure. The exterior is finished with your choice of materials — siding, stucco, stone veneer, or board-and-batten — matching your home's existing appearance.

Preventing Recurrence

Our rebuilds address the root causes of the original failure. We install premium stainless steel chase covers, proper step and counter flashing, kick-out flashing at the base, and ensure adequate ventilation within the chase. These measures prevent the water infiltration that caused the rot in the first place.
