Re: South Texas sun...and foundations...
Make sure you're watering AT least 18-24 inches away from your slab. The idea is for the soils that are drying under it, to pull the moisture, and soil, towards it. If you're watering right at the base, you may be causing accelerated damage.
Got some guys coming out to look, may not be as bad as I thought, but we're in a 60 year drought. Tell tale sign for me, is cracked mortar from a window, going "stair" stepped down the brick, to the slab. Gotta get the experts on it one way or the other, so I know if I'm all in or not.
Bottom line is, if worse case scenario, I can't afford to repair. Will have to walk away and take the hit. I called HUD, and everyone I could think of, but unless you're behind on mortgage or only make a certain amount, there isn't any help. I even called the "making home affordable" line, some new program under current administration. Couldn't understand a damn thing they said, other than, no help for you.
Maybe it's time to file the big "B".....and say f*&k it. Any suggestions fellas?
