Often, when a fireplace is spilling smoke into the home rather than drawing smoke up the chimney, the first conclusion most people reach (including some ill-educated chimney sweeps) is that the height of the chimney must be extended. Admittedly, making a chimney taller is sometimes the correct solution to a smoking problem, but the height of the chimney must be extended properly!
“Overstacking” is when someone attempts to extend the height of the chimney by simply adding terra cotta flue tiles to the top of the chimney, without building up the appropriate supporting brickwork surrounding it!
Folks often mistakenly assume that a little mortar between the top and bottom flue tiles will be adequate to hold the overextended flue tiles in place indefinitely, but this is not the case! It is only a matter of time before the mortar turns to sand, loses it’s adhesive qualities, and a precariously-perched overstacked flue tile comes tumbling down…..onto whatever may be below at that given moment! The unfortunate recipient of a falling flue tile could be your roof, your car, or your head! In any case, it wouldn’t be good because flue tiles are HEAVY, hard, and shatter like glass with very sharp edges!
If your chimney has been overstacked, either the bricks also need to be extended up to properly surround and support to the overs tacked flue tiles, or the overstacked flue tiles must be removed for safety purposes!

I was shocked by the amount of dryer lint that was cleaned out of my vent…but what really got my attention was the fact that MY DRYER HAD CAUGHT FIRE, AND I DIDN’T EVEN REALIZE IT! This was a little too close for comfort! I’ll be sure to have my vent cleaned on a regular basis from now on, AND to warn my friends and neighbors…Dryers can catch fire, and it could happen to you, too!
