Mold requires two things: moisture and a food source (typically dust).

Are you sure you have a foundation warranty and not a moisture termite warranty?  

Be especially mindful of any mold or moisture you see on the underside of the sheathing as this may indicate air leakage from the living quarters or a poorly ventilated attic. 

Washington is very rainy and I need to do these repairs now so that moisture can dry through the summer @Nathan G.Thanks for the response!  

On inspection, evidence of high moisture was noted in the basement.

There's no dripping/leaking going on, but there is definitely moisture on some parts of the walls. 

Make sure that the source of the moisture is also remedied-ie proper ventilation in the attic and basement.

There are also stucco inspectors who will drill a hole in each windowsill and do a moisture test.

I had a plumber look at it and cleaned/re-caulked where the foam gasket completely deteriorated and replaced the broken shower handle for 320.Then the restoration guy came and did not detect any moisture in the garage wall or upstairs bathroom. 

@Joey Allison Mold is fairly common in Arizona, once moisture is introduced it can take off pretty quick.Mold is also very treatable in most cases.
