I purchased a new home in spring 2005 in Leland,NC. Since then I was
replacing the flooring and found 5 10 foot long cracks in my on ground
poured concrete slab. I also have 6 vertical cracks on the outside of
my slab between ground level and the start of the siding.
The builder (Veranda Homes LLC ) tells me these are normal and only
offered to fill in the cracks. One crack is 1/4 inch wide and the rest
are larger than hairline. 2 of the cracks are continuing in a straight
line and do not look like "normal shrinkage cracks" . My back patio
vinyl framed sliding door is out of square also along with having
drywall screws poping out through the drywall 2 1/2 years later.
Do you think I should have a structural engineer look at the house?
I wanted to sell this house but I think a home inspector/ appraiser
will question all my external foundation cracks.

OP-

It is difficult to scale the cracks in your photos (a tape measure
would have been a good idea).

Concrete cracks.

The cracks look pretty normal for slab on grade construction.

I don't see any 1/4" cracks.

If it will make you feel better , hire a civil / structural engineer.

I have a foundation repair company coming to look at it.

I wouldn't be surprised if the said it needed a "repair".
