Winter in Blawnox is long and hard, the housing stock is old, and many chimneys predate modern liner standards entirely. This is what we actually find here, and what we check on every visit.
Water enters mortar joints and crown cracks across Blawnox, freezes hard, expands and pries the masonry apart a little further with every cycle. By late winter the evidence is spalling brick, open joints and leaks that were hairlines back in the fall.
Colonial, Victorian and early suburban homes give Blawnox some of the oldest chimneys in daily use - hand-laid brick, clay tiles, fireboxes built before modern codes. They reward careful inspection and punish shortcuts, and we report honestly what is sound and what is not.
A tall exterior chimney in a Blawnox January holds a column of heavy cold air that sinks into the room between fires, carrying creosote smell with it and making the first fire smoky. A clean flue, sound damper and right cap solve most of it.
A chimney fire can crack flue tiles and warp metal liners without leaving much evidence in the room - the fire burns up, not out. Any chimney in Allegheny County that has had one needs a full camera inspection before it is used again, without exception.

Once a year at minimum for a fireplace in regular use - and after about every cord of wood burned, whichever comes first. Blawnox fireplaces work for months in a cold flue, and creosote builds steadily the whole season. The sweep and inspection together are the safety check.
Not until a tech has seen how extensive the cracking is. Tiles are the barrier between hot gases and the masonry and framing behind them, and hard freeze-thaw cracks them in most older Blawnox chimneys eventually. Many cases call for liner repair or relining, which is a real fix.
Yes - in many Blawnox homes the furnace, boiler or water heater vents through its own flue in the shared stack, and oil and gas liners crack, soot up and block with age. A blocked appliance flue can spill exhaust indoors, so we inspect every flue in the chimney.
Often ice and flashing working together: ice dams push meltwater against the chimney, flashing loosened by freeze-thaw lets it in, and saturated brick passes it through to the wall. The stain shows by the fireplace, but the repair belongs at the roofline and the crown, in that order.
Late summer or early fall, before heating season. Every neglected chimney in Allegheny County seems to surface the same week in October, and that is when schedules fill. A sweep and inspection in September means your first fire is routine instead of a gamble on an unchecked flue.
No — and be wary of anyone who does. Every chimney fails differently, so a phone price is a guess that changes at your door. Our estimates are free: a tech looks at the actual problem, then gives you one clear price before any work starts.
