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.

I think an engineer would be a good idea.
Look for Forensic Engineer or Architect.
Applied Building Science of Charleston SC is one group that does this
kind of work.
A review by a pro will be worth the reduced worry, if that is all that
happens.

A 1/4" crack in a concrete slab is not normal. Those cracks together
with the fact that a door is out of square would indicate that
something is significantly wrong and you should get a structural
engineer in. In many states, new homes have warranties that cover
varying types of defects for different lengths of time, structural/
foundation type being covered the longest. With a 2 1/2 year old
house, I'd get this addressed now.
