Chimney Flue & Liner Repair
The flue is the one part of the chimney with a life-safety job: keeping 1,000-degree gases and carbon monoxide inside a sealed column until they clear your roof. A cracked tile or a gap between liner sections is the system failing at exactly that job.
Finding damage you can't see
Flue damage hides — that’s what makes it dangerous. Our camera scan maps every crack, spalled tile face, and open joint in the column. Common causes in DFW: a past chimney fire the owner never knew about, foundation movement racking the stack, and decades of acidic flue condensate eating mortar joints.
Repair or reline — matched to the damage
Isolated cracks and joints can be repaired in place. Damage spread along the column means relining: a stainless steel liner sized to your appliance, restoring a continuous sealed path. We quote both honestly — relining costs more once, repairing the wrong flue costs more forever.

Common Questions
The house shifted and the flue cracked. Is that common here?
Very — North Texas clay soil moves, and rigid clay tile doesn’t. It’s a top cause of flue damage in the area, and exactly why a Level 2 scan is smart after notable foundation work.
Is a cracked flue an emergency?
Stop using the fireplace until it’s assessed — cracks can leak carbon monoxide and heat into framing. It’s not a panic, but it is a before-the-next-fire repair.
