Don’t do it. Unless you want damage and water intrusion down the road. Make like a tripod or something to hold up the end. Don’t tap it into the brick. There are probably safe ways to do it. But I wouldn’t let someone pay me to do this, and I wouldn’t do it to a house I paid for myself.
u/BrimstoneOmega

Don’t.

If you do end up needing to cut any, cut them from the back, and stop just before the cut runs through the face, then snap them with a hammer or another stone. It will help make the cut less noticeable with a “live” edge.

It is. You may want an angle grinder with a diamond blade as well for cuts, but if you have a bunch you don’t need, you can try making hammer cuts, but it’s tricky with cultured stone to get right.

Yes, you will need to use mortar to stick these, probably would want to use a polymer modified mortar, it’s are a bit like a tile thinset. Don’t forget a trowel, 😉 These are cultured stone, but they do not come on a sheet. It will come in a box, ranging from like 8-13 square feet. You will need to buy a whole box, most likely. Get the old stuff off the scratch coat as best you can off wall. Then make like a suction cup on the back of your stone by making a rim around it with your mortar. Some guys will just plop a bit on the back and furrow a channel. I wouldn’t recommend this unless you have a boss breathing down your neck. Press if firmly and quickly (not hard and fast, if that makes sense) into the wall. Hold it for like 3 or 5 seconds. Done.

Do not, under any circumstances, take any of that guys advice.

First off, I’m a mason, not a concrete guy, take what I’m saying with a big grain of salt. My guess? Definitely not pocket change, but that stuff wouldn’t exist if it was more expensive than building it new. Building that new could be between $1500-2500 depending on various things. If you wanted to DIY building it yourself it would be like $300-500 or so in materials. My guess would be between $500 and $1000. But it could be $200 or $2000 for all I know, lol.

Google “mud jacking”. Typically you would want to hire this out, but there are DIY kits, and it’s not like this is gonna make your house cave in if you mess it up. But you could very easily make it worse.

Guess an extra cube of brick and some mortar were to expensive, huh? JFC…
