Chimney inspection $59, and free quotes with no obligation
An oversized masonry flue does not draw properly, and a cracked one lets combustion gases into the house. A stainless liner fixes both by giving the appliance a sealed flue the right diameter.
Measured, not guessed. The appliance decides the liner.
A camera run down the flue shows what is left of the existing liner, and the appliance output sets the diameter.
A stainless liner is dropped the full height of the flue, insulated where the appliance or the code calls for it.
Connected at the appliance and terminated at the top of the stack, so nothing leaks into the chimney cavity.
There is no point lining a stack that is coming apart, so any masonry repair happens first.
These are our own jobs, not stock photography.

You cannot tell from the firebox. It takes a camera run down the flue, which is part of a chimney inspection. Tile shards in the firebox are the one sign you can spot yourself.
Clay tile is what most older Philadelphia chimneys were built with, and it cracks as the stack moves and heats. Stainless goes in now because it drops into an existing flue in one piece and is sized to the appliance.
Usually, yes. A gas appliance vents cooler and wetter than a wood fire, and an oversized masonry flue lets that moisture condense inside the brick. A correctly sized liner stops it.
It is the thing an inspection most looks for. A broken flue can let combustion gases into the living space, and carbon monoxide is odorless. The EPA's summary of carbon monoxide indoors explains why.
A stainless liner sized and fitted correctly is a long-term fix, not a patch, and it still wants the same annual sweep as any other flue. Call (215) 201-4371 about your Philadelphia flue.
If there is tile in your firebox or an alarm going off when the fire is lit, that is a flue problem.
