stone on my house is crumbling
I'm checking to see if there is anybody who has experience/knowledge of stone. I bought this home a few months ago, it was built in 1950 and the construction is stone. Over the winter I have notices small pieces of stone falling off the house and in some cases the mortar joints are loose. It appears only certain stones are eroding and there have some indication of patching.
Some research has cautioned against sealing the stonework. Also can somebody identify the stone, is it sandstone? Any suggestions welcome.

Maybe Stoneseller can comment on the type of stone you have. You probably need to have the stonework repointed. Water gets in there, freezes and busts the stone apart. This happens with brick, too.

Are these sections located in areas that typically are covered in drifting snow and/or ice during winter months?

Yeah - what area is that from?....is this typical throughout? Do you have another pic of any good, intact stone?
It really looks like surface delamination/spalling from a "sandy" type stone, unless I'm just seeing a patched area. The surface of the weak, permeable stone could very well be wicking moisture in and the freeze/thaw action is aggravating it. Your mortal joints actually don't look too bad. My gut reaction would be to patch the voids and seal with a sika product or boiled linseed oil?

The motar joints don't look too bad either.

It's actually "mortar" partner.
The stone does look to be a sandstone material and I would also suspect the damage shown is freeze/thaw related. To identify, talk to local brick yards about the types of stones that were available locally in your area when the house was constructed. Is difficult to tell the extent of damage from the close-ups, but obviously needs to be sealed to prevent moisture absorbing into the stone.

Haha..that's funny. I f&*ked up and then you f&*cked up in correcting me. Or was that intentional? Righhht. Having an immortal joint would help though....

Bottom line is, you want/need a fix.....and I'd personally seal it up. What did you read that said something to the contrary? I'm sure you could knock off the loose stuff and color mix a mortar or mortal to patch it. Structurally, I think you're fine....I'm presuming your concern in aesthetics?

Looks like a type of sandstone to me. My house, along with many in my neighborhood, have sandstone although much redder. There was damage when I bought my house and I hired a restoration mason to repair it. He told me that you can't use contemporary mortars around this stone because the mortar is too hard and would cause problems with the stone. He mixed his own mortar to mimic the mortar of the late 19th century. I forget what ingredients he was excluding. This makes me wonder if your house was not built or repointed with a hard mortar which is causing the stone to spall.

Good point Kerry - I suppose I forgot to say...repair with a mortar specifically tailored to sandstone. Don't just go to Lowe's and by a mortar bag and trowel.
google turns up some interesting stuff - try the US heritage group.....I know we've used some of their products on bridges before. HS 60 Sandstone Repair Mortar
