- Clean • Safe • Reliable • Done Right
The smoke chamber is the crucial space above your firebox. We parge its walls smooth for a safe, efficient draft. Since it is interior work, we can repair it year-round.
A rough, deteriorated smoke chamber is both a draft problem and a fire-safety problem. Creosote clings to every rough ledge and becomes very hard to clean, while open joints can let heat migrate toward the wood framing around your chimney. Sealing the chamber protects your home, improves how your fireplace pulls, and is often needed to pass a Level 2 inspection. It’s one of the most common issues we find — and one of the most important to fix.
We treat your home like our own – careful, clean, and respectful, especially around kids, seniors, and pets.

Common questions about smoke chamber repair. Still unsure? Just give us a call.
It’s the funnel-shaped space directly above your firebox and damper, where smoke gathers before it enters the flue. On older chimneys it’s usually built from stepped (corbeled) brick, which can leave rough ledges and gaps.
Yes. Smoke chamber repair is done from inside your home, through the firebox — not on the roof or outside. That means we can carry it out year-round, including in winter and in wet or snowy weather, when exterior masonry work usually isn’t possible.
Common signs are a smoky-smelling or poorly drafting fireplace, crumbling mortar or soot falling into the firebox, or a failed Level 2 inspection. If you’re not sure, we can inspect it — often with a camera — and show you what we find.
Parging is applying a smooth coat of heat-rated (refractory) mortar over the smoke chamber walls. It seals the open joints and creates a continuous, smooth surface so smoke rises cleanly and creosote has far less to cling to.
It can be. Creosote is highly flammable and builds up fast on rough, angled walls, and open joints can let heat reach nearby wood framing. Sealing the chamber is an important safety upgrade.
Smoke chamber repair parges the funnel above the firebox smooth with refractory mortar for safe, clean draft and less creosote — interior work we can do year-round, across Greater Boston. Call (781) 782-8727.
