Why DFW Chimneys Develop Cracks and Leaks
North Texas weather is brutal on chimneys. Summer heat bakes your masonry. Winter freezes crack the mortar. Spring storms soak the brickwork.
The freeze-thaw cycle is the chimney’s worst enemy. Water seeps into tiny cracks. Temperatures drop, water expands, and the cracks grow. Repeat this cycle for years and see the condition of your chimney deteriorate steadily.
Older masonry chimneys in Arlington and Dallas have mortar that’s decades old. It crumbles. Bricks loosen. Plano’s tall chimneys expose more masonry to the elements. Frisco’s prefabricated chimneys have metal components that rust and corrode.
Your chimney crown cracks over time. Rain seeps through. Water runs down your flue. It damages your firebox and rusts the damper. The flashing loosens or rusts. Water leaks from gaps into your home. Small cracks become big problems. And ignoring chimney repair costs you more money in the long run.
