Chimney repair for Taylors' 1980s–2000s subdivision homes — chase cover replacement, firebox panel repair, damper service, and gas log liner correction. Written scope before work begins.
Taylors' 1980s–2000s construction has reached three distinct age bands with different primary failure modes for each decade of construction.
Many Taylors subdivision homes had gas log sets added to existing wood-burning factory-built fireplaces, often when the home changed owners. A wood-burning flue is sized for the large firebox opening and the high heat output of wood fires — typically 8×8 to 10×10 inch flue area. A gas log set produces far less heat and exhaust volume. The oversized flue allows combustion gases to cool before reaching the top, causing water vapor in the gas exhaust to condense inside the flue. The condensate is mildly acidic and deteriorates clay tile mortar joints over time. Whether a liner is required depends on the specific appliance and flue dimensions — assessed on-site.
These six repair categories cover the majority of work performed on Taylors subdivision chimneys.
Rusted galvanized cover removed and replaced with stainless steel or aluminum. Interior chase is inspected for framing moisture damage before the new cover is installed and sealed.
Cracked refractory panels replaced as a matched set for the fireplace manufacturer and model. Through-cracks require replacement; surface hairline cracks are assessed individually before replacement is recommended.
Corroded pivot, worn seals, and warped damper plates assessed. Damper assemblies that no longer seal can be replaced with a top-mount damper that seals at the flue top rather than inside the firebox — eliminating the corrosion problem at its source.
Where a gas log set is connected to an oversized wood-burning flue, a stainless steel liner sized for the appliance's BTU output eliminates the condensate issue and brings the installation into compliance with appliance manufacturer requirements.
Dried and cracked sealant at base flashing and counter-flashing joints repaired. Where original flashing is rusted or improperly installed, full flashing replacement restores a watertight chimney-to-roof seal.
Cracked or eroded mortar crown on wood-framed chase top repaired or rebuilt to seal the chimney perimeter. On masonry chases, a full crown rebuild includes proper slope, drip overhang, and refractory-compatible mortar.
