3rd Stage Creosote Removal Specialists
How Creosote Becomes Chimney
Glaze
Creosote is a liquid that condenses onto
the inner walls of connector pipes and chimneys as wood smoke
cools. When creosote dries, it gradually hardens, taking the following
forms: Stage 1 (velvet soot), Stage 2 (porous and crunchy in makeup)
or Stage 3, shiny, rock-hard chimney glaze. The buildup of chimney glaze
is denser and harder than brick, and sticks to the chimney inside
walls. Chimney brushes can’t sweep it out and any blow strong
enough to break the glaze could damage the chimney itself.
Why does chimney glaze form? Fresh layers
of creosote rapidly buildup, accumulating quickly when previous creosote layers don't
dry completely. The newly formed layers then insulate the partially-hardened
previous deposits from the heat of the wood exhaust that dries
them, resulting in a heavy buildup of sticky creosote, which eventually
solidifies. This creates the stone-solid substance known as glaze.
The excessive creosote accumulation that leads to glaze formation
is usually caused by the improper burning or venting of airtight
wood stoves. Specifically, glaze will often form when the chimney
is larger than the vent opening on the appliance (causing sluggish
draft), when unseasoned or wet wood is burned, or when the draft
control on an airtight appliance is habitually set too low, causing
the fire to smolder. Stage 3 creosote removal is crucial to prevent chimney fires protecting your family and home.

Our Chimney Deglazing Procedure:
Most chimney glaze/creosote removal treatments require
three visits over two weeks. On the first visit, we score the surface
of the glaze with a chimney brush, then saturate it with TSR, a
chemical reactor. TSR needs to be above 50 degrees to work, so glaze
removal done best in the warmer spring and summer months. In colder
weather, you must have at least four fires during the following
week, opening the draft control, and damper or baffle-bypass on
your stove enough to allow as much heat as possible up the chimney
(we recommend you monitor these fires in case the glaze ignites).
One week later, on the second visit, we sweep out the broken-down
glaze and re-apply the chemical to any remaining glaze. On the third
visit, we remove the last of the residue and spray the flue with
a chemical that neutralizes the TSR. Occasionally, when deposits
are extra dense or extra thick, additional treatments may be needed for final cleaning
to break down and remove all the layers.
