House seems to have started cracking in half


I agree that the house is settling.Take another picture from the back yard, centering the back door. Hold the camera level to see the foundation line. The door lintel is of proper length, one brick width to each side of jambs. (hence the cracks traveling away from the door on horizontal) Open at the top is bending foundation or slab on grade? down on the side opposite fire-place. Usually---- f.p. don't move or settle with the 4x7'x12" deep spread footing. And the crack would be on the other side of door- weakest link. You can hit the post bottoms with a sledge- if it moves- it's the wind lifting roof.
That is the joint of the bay header/end of lintel.
Be safe, Gary

1) This would seem to indicate the foundation could be sinking on one(or both) sides. On the outside porch pic, there looks to be a heavy fireplace nearby which is probably tied into the structure, and the dining room partition wall looks like it's splitting at the top-indicating downwards force.

2) If the cantilevered porch beam is levering a stress crack, wouldn't the gap return to same(0)? Check with a level on both sides.
The porch beams are not really cantilevered, They only go about 12 inches into the roof and nailed to the existing joists and header. I THINK. It has been about 20 years since I rebuilt it.

Do you think it would help if I repositioned the posts on a Simpson strong-tie, rather than leaving it as is just sitting/attached to an aluminum connector (for lack of a better word)

BTW, I can not thank you all enough for the time and advice you are providing.

It has been so many years since I really did any type of construction, I am even having trouble remembering the correct terminology.
So, thanks for putting up with me

I'm in no way qualified to answer the question, but wanted to send in what I have seen in the past that caused cracks like that.
If someone made a change to the half wall by the door. Like removed the top half to open it up. If it wasn't supported correct when they did it or the didnt' support it right.
Or like someone said about if part of the foundation maybe has washed out some and causing stress, where maybe its been holding up but the wind storm cracked something and it dropped. Not sure if I can explain what I mean. ( like say you go out onto a branch on a tree and you can see it bending but it holds. If you were to like jump on it or swing on it that would make it crack. )
It looks like there's been some work done at the top of the post of that wall. Like if there was a wall and it was patched if the top half was removed. It may be just the way the picture was taken.

I see no evidence that the foundation is settling. If the foundation were settling, the crack would almost certainly begin at foundation level and extend up to the top of the wall. There would also be evidence in the foundation itself, specifically cracks in the slab. In order to check the foundation for settlement, you will need to rent or borrow a high quality level, and survey the elevation of the slab approximately every 2 or 3 feet in each direction.

I do this using a fluid level, the particular one I use is made by the Zip corporation, however there are other levels that work just as well. You need one capable of absolute accuracy of at least 1/8 inch. When you have completed the survey, you prepare a contour map of the floor, which will show how much settlement, if any, has occurred, and where. Remember, it is likely that the slab was not poured perfectly level or flat, so an 1/8 inch lower here or there probably means nothing. My guess is you will find that the foundation is fine.

My initial guess is that the post referencing a problem with the lintel is correct.

On thing to take into account is a few inches to the left of the crack, the wall ends. The bay window is a stick construction.

There must be a large header attached to that wall there, that spans the bay window area

So this would lead me to believe that the foundation may not be the cause. I would guess that the bolt that holds down the header is directly behind the crack

the pic in post 10 makes me think its a roof lift. ii this is a block wall with brick veneer on outside? if so there may be an anchor bolt at this point thru the top plate that the main roof sits on, they are usually grouted down a couple of blocks to hold the bolt

No, This is a block wall, period. Covered with a veneer of house paint.

I tend to agree with your assessment of the roof lift.
I imagine I should be able to get a much better picture of it, if I open the drywall on the inside.

Sounds like that is the only way to verify a roof lift
