Creosote Removal for Level 1, 2, and 3 Buildup
PureFlow removes dangerous chimney deposits ranging from light soot to heavy glazed creosote, helping reduce chimney fire risk and restore safer draft through the flue.
Understanding the Service
What Creosote Removal Covers
Creosote is the flammable residue left behind when wood smoke cools inside the chimney. Light, flaky deposits are considered level 1. Sticky, tar-like buildup is level 2. Hardened glazed buildup is level 3 and is the most dangerous.
Our service is built around the actual buildup level found in the flue. We use the right removal approach for each stage so the chimney can draft better and operate more safely.

Our Process
How We Handle Level 1 to Level 3 Creosote
Inspection and Classification: We first determine whether the chimney has light soot, sticky buildup, or hardened glaze.
Containment Setup: The work area is protected and negative-pressure methods are used to keep soot out of the home.
Mechanical and Specialty Removal: Rotary brushing, scraping, and appropriate specialty methods are used based on the creosote stage present.
Final Safety Review: After removal, we review the visible flue condition and let you know if more service or repair is recommended.

Signs You May Have Heavy Creosote
- Black shiny buildup visible above the damper
