Once moisture starts getting behind stucco, things can go south in a hurry.

I'd also look for ANY moisture invasion issues like roofs or around in the baths and kitchens. 

@Leslie Crosten that attitude will get you far in life, heres a little education for ya, diffrent areas have diffrent soil conditions, diffrent moisture conditions, etc so many variables, when you want a bunch of people on a forum to give u advise, its beat to give the most detailed info, location, age structure type, interior exterior wall, structural wall partition wall etc.

The shrubs/piles of leaves will hold moisture as the ice and snow melts and it can be a train wreck if it's up against the structure. 

You could also get rid of small chunks and black top it, probably cheaper, they may want to bust it up leaving it in place for moisture and freezing, your original probably wasn't think enough and reinforced.

Or, it could be totally surface from moisture accumulating behind the file cabinets.

The problem with "green" pavement is that is main function is to allow moisture to drain into the subgrade.

Half way down the left side of the screen is a PDF titled "A Brief Guide to Mold, Moisture, and Your Home"If the amount is much bigger that 4' x 8 or you just don't want to hassle with it, then you should look for someone who does "mold investigations" rather than mold remediation.

One contractor had included the cost of a 2nd Furnace that was not necessary & another wanted to add $3500 for a 'moisture removal system' in the 13 x12 Hot Tub room again not required.

Tile better resists moisture than hardwood.
