hello friends, long time no see. the drought has done a number on the clay upon which my house sits, it seems. i dialed back my watering when we were rationed to two days a week, and in the last 2 months, i've had several cracks in the drywall appear throughout the house. more troubling, i found about a 16 inch stress crack across a few bricks coming out of the corner of a window. on the same wall (within a few feet) there is also some separation in the mortar from the slab to the eaves, and two window frames on that exterior wall are also separating from the masonry. the gaps are between 1/16 of an inch or so, to nearly a quarter inch in spots. here's the deal. foundation problems are not that uncommon in my neighborhood. however, i have walked around the perimeter several times and i cannot find any cracks in the slab itself. based on the above, is it possible that the house has shifted as a unit, without any fracture to the slab? second question. how much does foundation repair generally cost, and how long does the process take? third question. we have never intended to stay in this house for a long time. what kind of drop should i expect to see in my home's value (as a percentage?) thanks, and i'll hang up and listen.
