WHAT TO EXPECT FROM A PRE-FAB FIREPLACE
On average, a pre-fab fireplace can last about as long as other major home appliances, like a quality stove or refrigerator. Annual maintenance and cleaning is similar to a masonry fireplace, and homeowners should always be on the lookout for moisture, cracks, and soot buildup in excess of 1/8th of an inch.
COMMON ISSUES WITH PRE-FAB FIREPLACES
Many pre-fab chimneys, especially older units with an "imitation brick" stack above the roof, seem to be a preferred nesting site for birds in our area. It's not unusual for our chimney sweeps to literally remove buckets of nesting material from these chimneys!
This nesting is a major fire hazard, and also blocks critical air passageways between layers of metal chimney pipe, causing the chimney to overheat. Both situations are prone to creating house fires, so paying special attention to this phenomenon is important for both homeowners and cleaning professionals.
