It’s not something you really want to acknowledge. You tell yourself it’s an optical illusion, or clutch to the consoling thought that, hey, the tower in Pisa has leaned for centuries.
But a tilting chimney is a serious home problem that should be dealt with as soon as possible. The bricks could fall on someone’s head or crash on your roof. Water and bugs could get in the gap where the chimney has pulled away from the siding. The chimney liner may even be cracked, leaking combustible gases into the home. And since the chimney is probably connected to the foundation, there could be problems there, too.
The good news is that with today’s foundation repair methods, it may be possible to move your chimney into its original plumb position without incurring the high cost and disruption of demolition and rebuilding.
