Smoke Chamber Repair
The Smoke chamber is the area directly above the fireplace damper that helps smoke find it’s way up into the flue. Shaped like an upside-down funnel, smoke and hot gases are in direct contact with the tapered smoke chamber walls as you burn your fires. For this reason, building code requires that the smoke chamber walls be at least 8” thick and “parged” smooth.
Parging is the process by which the inside surfaces of the smoke chamber are sealed with a layer of mortar in order to close off any holes or gaps where heated flue gases or carbon monoxide might escape, possibly causing a fire or physical harm to the occupants.
In some cases, the smoke chamber has not been parged, or holes in the parging may be present. In addition, sometimes the bottom flue tile is not sealed properly to the smoke chamber.
CHAMBER-TECH 2000 is a specialized insulating mortar specifically designed to address smoke chamber deficiencies. Able to stick to vertical and inverted surfaces, CHAMBER-TECH 2000 can be applied and smoothed on the smoke chamber walls to seal off and insulate this critical area of your fireplace system.
CHAMBER-TECH 2000 will insulate, reducing conduction to combustible materials, adding needed structural strength and at the same time shaping the smoke chamber to help reduce turbulence and establish a strong draft to keep your fireplace from smoking up your home!
Installing rear access doors will make future cleanings of the smoke chamber much easier. Let’s talk about whether this chimney upgrade/repair will work for you.

Everything from your company has been done in a professional manner! The person who came out to sweep my chimneys answered all my questions with pictures and a book full of before and after pictures of the most commonly needed repairs, and I was very impressed. Later on, you came back out to install chimney caps on both fireplaces. I was very please with all your work. And yes, when I need another chimney cleaning, I’ll definitely use A to Z again. You are professional and I give you very high marks!
