Creosote is what burns in a chimney fire. Third-degree creosote is glazed and hot enough to crack flue tile, and removing it is the entire point of an annual sweep.
High-altitude UV, big temperature swings and real snow load mean assemblies rated for a mild climate fail early here.
Most chimney leaks are not the brick. They are a failed crown, missing cap or bad step flashing where the stack meets the roof - which is why repointing a chimney that leaks through the crown fixes nothing.
What the job includes
- Annual sweeping and creosote removal
- Level 1 and Level 2 inspections
- Stainless cap and crown repair
- Flue liner installation
- Flashing and leak repair
- Dryer vent cleaning
