Non-Air Tight Smoke Room Repair
The smoke chamber is the connection between the chimney flue and the fireplace hearth. It is an essential element, acting like a funnel to facilitate the evacuation of combustion gas, and is often neglected when designing and performing fireplace maintenance. If the sweeping is done only from the outside of the chimney, the reversed funnel shape prevents proper cleaning and inspection (the wide part faces the floor, therefore is not accessible from the top).
Drastic temperature changes can create condensation and a premature deterioration of the masonry. Application of high temperature refractory cement on the whole smoke chamber improves not only the efficiency of the chimney air flow, but also greatly increases safety in case of chimney fires since any cracks can leave adjacent combustible materials exposed. The 4 Seasons Chimney Sweeping technicians can advise on the necessity of performing such a repair.
