What is Smoke Chamber Parging?

Your chimney may look like a neat stack of bricks and mortar. However, it is actually a complex ventilation system. One of the most important parts of the chimney is the smoke chamber, which plays an integral role in pushing smoke and combustion byproducts up the flue and out of your home. This allows your family to enjoy the warmth of your fireplace without the smoke and fumes.

The smoke chamber is the area located directly between the firebox and the chimney flue. Its inverted funnel design compresses smoke and gases, allowing them to transition efficiently from the firebox to the flue and exit the top of the stack, preventing downdrafts and smoky fireplaces. Although it is difficult for homeowners to access, it is critical for a proper “draft.”

What is Smoke Chamber Parging?

Parging is simply the process of smoothing the smoke chamber surface. Until the 1980s, most smoke chambers were constructed with “corbelled” bricks, an outdated technique in which bricks are stacked like steps. Parging covers these jagged areas and any gaps in the mortar, creating a smooth surface that allows smoke, soot, and creosote to rise through the flue without sticking to the chamber’s interior walls.

When is Parging Necessary?

According to the National Fire Protection Association (NFPA 211), all smoke chambers must be parged smoothly. Parging may be required if:

  • Your chimney is older: Many older and historic homes have corbelled brickwork that poses a severe fire hazard, which is why corbeled brick is no longer compliant with current building and fire codes.
  • There is visible damage: When a chimney sweep identifies cracks, holes, or falling mortar joints during an inspection.
  • Fireplace fills with smoke: Smoke is entering your living space instead of going up the chimney.

Parging Tips for Older and Historic Residences

When restoring a historic chimney, structural integrity and its original aesthetics must be maintained while complying with modern safety codes. In historic homes, removing bricks to access the chamber can weaken the entire stack, causing it to lean or even collapse. Our solutions are easy to apply, making repairs simpler without removing any of the existing brickwork.
