What Is a Fireplace Smoke Chamber?
The smoke chamber is the open space right above your firebox and right below your flue opening – it essentially looks like an upside-down funnel that connects these two areas. Many smoke chambers of the past were built with a corbeled, or stair step, design, but nowadays it’s recommended that they be smooth and seamless to ensure proper smoke flow.
What does the smoke chamber do? What’s its purpose? The primary job of a fireplace’s smoke chamber is to funnel smoke, heat, and combustion gases from the firebox into the narrower flue, so they can exit the home as efficiently as possible. The smoke chamber is designed to gradually transition the wide opening of the firebox to the smaller diameter of the flue, helping to maintain a strong, steady draft.
Without those slanted walls for smoke to travel up, the fumes from your firebox would simply bounce around – sure, some would make it up the flue, but a lot would end up back in your living space. The smoke chamber reduces turbulence and promotes the smooth upward flow of hot air and smoke.

Smoke Chamber Parging Near Me: What Does Parging Mean?
If you’ve checked out anything about smoke chamber repair, then you’ve probably seen the word “parging” come up a lot. Parging is the process of applying a thin coat of mortar or cement-like material to a masonry surface. In the context of your smoke chamber, it’s the process of smoothing out its walls.
When would a smoke chamber need to be parged? If your fireplace is older, there’s a good chance that your smoke chamber is corbeled, which can lead to issues, like creosote building up in the nooks and crannies, as well as backflowing of smoke. In addition, a smoke chamber that’s facing damage could be repaired with a parging service.
Professional chimney technicians, like the crew here at Sleep Easy, use high-temperature, fire-resistant materials for parging to ensure durability, long-lasting results, and compliance with safety codes. In fact, many modern building codes require that smoke chambers be parged smooth.
All in all, whether it’s part of new construction or a retrofit for an older fireplace, smoke chamber parging is a practical step toward improving draft, enhancing safety, and prolonging the life of a chimney system. We use industry-leading Chamber-Tech to make repairs and seal cracks, fill holes, smooth rough patches, and leave you with a completely smooth, sealed, insulated smoke chamber.
What Are the Most Common Causes of Fireplace Smoke Chamber Damage?
Now, some smoke chambers were simply built incorrectly from the get-go, but other times parging is needed to repair damage. How does this area, that’s hidden away and seemingly not exposed to much, experience damage?
- Moisture: Moisture from the fire (when the flames burn through wet wood and create acidic byproducts), as well as moisture from chimney leaks, can lead to cracks and decay within the smoke chamber. Once cracked and damaged, the smoke chamber can allow heat and byproducts of combustion (including stray sparks and hot embers) to access wooden framing, insulation, and other nearby combustibles.
- Heat Damage: Other times, cracks and gaps are created from heat damage. Like with water damage, these openings can also allow gas, heat, and smoke to enter the home, which could lead to carbon monoxide exposure, smoke inhalation, or fire hazards. Likewise, a damaged smoke chamber can slow the exit of smoke and lead to backdrafting.
- Creosote Buildup: Creosote is a tacky and flammable deposit that forms as wood is burned. The less smooth your smoke chamber is, the more areas creosote has to cling to and form. These deposits can be tricky to remove, especially if multiple layers have built up…but if it isn’t removed it can break down the smoke chamber’s materials, or potentially cause a rapidly spreading chimney fire.
- Flawed Design: Another common cause of smoke chamber safety and performance issues is a flaw in design. For many years, smoke chambers were built with corbelled brick steps, which caused resistance for exiting smoke. This design resulted in smoke problems, as well as the build up of even more creosote in the chimney system.
