We Handle Smoke Chamber Parging

Unparged smoke chambers create more friction and turbulence, and can allow excessive heat to pass through the smoke chamber walls and start a fire.

The smoke chamber is the area directly above the fireplace damper that helps smoke find its way up the chimney’s flue. Shaped like an upside-down funnel, smoke and hot gases come into 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.

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. Cracks and holes in the smoke chamber can be very dangerous. Parging is the process by which the inside surfaces of the smoke chamber are sealed with a layer of mortar. Parging smooth seals off any holes or gaps where heated flue gases or carbon monoxide might escape, reducing the risk of a fire or physical harm to the occupants.

About Chamber-Tech 2000

A smoke chamber parged with Chamber Tech 2000 significantly decreases the chances of an accidental fire and increases draft.

Smoke chamber walls without properly insulated parging make it more difficult for your chimney to draft properly and can be a major fire hazard. When parging smoke chambers in the Sacramento area, A to Z Chimney Services’ technicians use Ahrens’ Chamber-Tech 2000, which is a specialized mortar engineered specifically for smoke chambers.

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.

Unparged smoke chambers create more friction and turbulence, and can allow excessive heat to pass through the smoke chamber walls and start a fire. A smoke chamber parged with Chamber-Tech 2000 significantly decreases the chances of an accidental fire and increases draft. 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.

Dear A to Z Chimney

I just wanted to thank you from the bottom of my heart for the great service you have done for me. I am an avid wood burner and love to burn my fires just about every evening. There’s nothing like the simple pleasure of curling up next to a warm and cozy fire during those cold winter nights.

Unfortunately, I had a chimney fire which did extensive damage to my chimney and it had to be re-lined with a new Stainless Steel Liner.

Last year, I hired a different company to come out and sweep my chimney. The sweep from that company tried to use high pressure sales tactics to get me to do the repairs. His poor attitude and high pressure turned me off so badly that I decided not to have them do the work.

This year, I hired your company and Chris Donovan was such a gentleman! He gave me the same bad news, but this time I could see it with my own eyes on the screen as he video scanned my flue. He was also much more knowledgeable and informative and really took the time to help me understand. He did not talk condescendingly, and there was no pressure whatsoever.

Consequently, I did hire your company to come back and complete the needed repairs, and was absolutely delighted!! Not only did Chris come back, but Aaron, the owner came, as well. I was delighted to know that the owner was personally seeing to the work. In the process of repairing my chimney, some other minor problems were detected, and they fixed them at no additional charge!

In addition, when everything was done, they did a spectacular job cleaning up every bit of their mess, and I couldn’t even tell they had been here.

Thanks again for the great service you provide! I will use you again and again, and refer you to my friends.
