Leak Detection:

Maybe putting some photos of the your yard and the outside of your house on
your website would help. That may help people here see how the ground is
graded, whether there are flower gardens etc. near the house that trap
water, etc.

Also, when it rains, are there puddles on the ground near your house or does
the water run off away from the house?

Judging from some of the damage shown by some of the photos, it looks
to me like a drainage problem allowing water to accumulate at the base
of the exterior walls. From there it seeps into the house.
