Hello!
New member here, my name is Johan and I am a carpenter, working at a prefab company.
Now I have some thoughts on what can be done with this chimney to repair it in the cheapest way. My idea is to knock off broken stones and re-mortar/grout what is bad, one side seems a bit healthier than the other. Any specific mortar recommended? Anything else to consider?
 
  • Damaged brick chimney on a tiled roof, with visible cracks and worn sections, possibly requiring repair or re-mortaring for restoration.
It probably takes just as long to try to fix the frost-damaged chimney (it won't be good anyway) as to take it down and build a new one. I assume it's an old house with a "new" concrete roof where the chimney was left to hang in there a bit longer. Now you have the opportunity to get tiles with the same color as the rest of the roof. As for the antenna, one might wonder if it's the bands for it that are holding the chimney together ::)
 
Talked to our mason when we were slip casting our pipes. He said that one of the worst stresses comes from the TV antenna when it's windy. Tensions in the joints loosen and absorb moisture in the fall/winter which then "explodes" in sub-zero temperatures. Recommended to move the antenna to a separate mount on the ridge or similar. Then make sure you don't drop any stone in the pipe when you pick up. You'll have problems = chisel up the chimney from the inside.

Regards, Magnus (also have the same problem but waiting a bit longer)

:'(

ahh can imagine that, the antenna will go in any case, satellite dish it will be 8-)
"half" the chimney looks okay, will see if it can be tidied up so that it gets approved anyway, then we can make a new one a little later, there's much else that is more fun to tinker with first...
 
The passage through the roof is a critical spot—how does it look there? Poking around in old junk usually ends up costing more time and money.
 
It is possible to cover it with sheet metal, but I wouldn't do that, as it will probably result in tiles falling into the pipes, but perhaps you can repair it as best as you can and then cover it with sheet metal?

A good guess is probably that if you don't make a temporary fix now and rebuild it properly when you have time, it will take the same time to rebuild it as to repair it thoroughly.
 
Don't remove the antenna, otherwise, the chimney will probably collapse hehe... ;)
The only thing to do is to take it down and rebuild it... the condition inside is probably not so good considering the outside. Can you access it from the attic??
 
no, in the attic you can't access anything, but from there the chimney stack looks great, then it looks much better on the other two sides that aren't in the picture, no frost damage at all, I'll see what I do, what can it cost to hire a mason to make a new top then? how long does it take to do it yourself?
 
One idea is to maybe polish it from the outside if it is intact on the inside.
 
But if one would like to fix their chimney,
what type of mortar should be used? Plaster mortar C or Plaster mortar B or what?

I have some loose stones on the south side.
