Smoke Chamber Parging Toronto — Smooth the Chamber, Prevent Fires
The smoke chamber is the corbelled brick zone above your firebox. Rough brick equals turbulence, creosote, and fire risk. Parging turns it into a smooth funnel.
What's included
- Camera survey of existing chamber
- High-temp refractory parge (Chamber-Tech 2000)
- 1/2-inch smooth coat applied top-down
- Improves draft measurably (before/after test)
- Reduces creosote formation up to 60%
- 10-year manufacturer warranty
Why Smoke Chamber Parging matters in the GTA
Older Toronto fireplaces have corbelled (stepped) smoke chambers that trap smoke, cool it, and cause creosote. Parging with refractory cement turns them into smooth, high-flow chambers.
Most pre-1970 GTA fireplaces fail modern NFPA 211 smoke-chamber standards. Parging brings them into compliance without a full rebuild.
What the visit looks like
Camera scan to grade current condition, mask the firebox and hearth, spray or trowel Chamber-Tech 2000 in a 1/2-inch smooth coat top-down, cure for 48 hours, then a before/after draft measurement.
Real Toronto pricing (2026)
Standard chamber: $650–$950. Complex or oversize chambers: $1,200–$1,600.

What Toronto homeowners say
"Booked a sweep and WETT inspection before winter. Crew arrived on time, laid down drop cloths, and walked me through the report photo by photo. Fixed pricing, no upsell — exactly what was quoted."
— Sarah M.
"Cracked clay liner in our 1962 fireplace. They installed a stainless liner and new cap in one day and the draft is perfect. Warranty paperwork emailed the same evening."
— David R.
"Called for a raccoon in the flue. They removed it humanely, sanitized the smoke chamber, and installed a stainless cap. Fair price, no drama, and they even followed up a week later."
— Priya S.
