Smoke Chamber Code Upgrade

Smoke chamber code upgrade to bring your fireplace to compliance with NFPA standards. NFPA 211 states that all smoke chambers for wood-burning masonry fireplaces must be parged smooth with high-heat cement. Without this cement lining in the smoke chamber, small imperfections in the masonry of the fireplace or chimney can lead to devastating damage to your chimney and home.

Smoke Chamber

The smoke chamber is where the final steps of the combustion process take place. Even small unnoticeable gaps or cracks in the smoke chamber can cause serious issues.

Flammable creosote blockage buildup due to smoke not being able to quickly escape up the flue liner and out the chimney.

Heat spreading from inside the the chimney to surrounding items and nearby walls creates creates a serious risk of a house fire not to mention the carbon monoxide that could be leaking out.
