dealing with subsidance - need an engineer?
I recently found this forum and have learned a lot by reading old posts. We have a 1922 foursquare in SE Virginia, that we bought just over a year ago.
We had some flooding in November during a Nor'easter. The water didn't get into the living space of the house, but did go into the crawl space and was perhaps knee deep in the very front of the house, a little less deep towards the back.
Since then, I think the house may have settled or subsided. There are two new cracks in plaster that are larger than the older ones, and some of the double-hung windows don't want to open (all of the windows were painted shut when we bought the house, these are of the ones we had managed to free). At first I thought they might be swollen from the increased humidity, but they still don't want to open. In addition, one of the doors is sticking now. (Interestingly, two doors that used to stick are now free.)
The soils on our lot are mapped as fine sandy loam, underlain by sandy clay loam (Augusta and Tomotley series). Parts of the yard are pretty poorly drained, I think in part because the land is so flat. The house is on what I think are called piers, with the crawlspace bricked in on the outside. The piers themselves are brick, at least on their faces. There is no basement.
We are assuming that we need someone to come and look at the situation. Our neighbor gave us a contact for a civil engineer. What types of things should we be looking for in a professional to assess our house and determine if and what needs to be done? Apparently, flood insurance does not cover subsidance issues, so we didn't get any hints there at how to proceed. This is our first house and we don't have much experience with foundation-type issues.
Thanks for any advice!
