We have a floor that is rising in an area, and weren't sure if we had a foundation problem or what. We had a representative (BJ Browning) come out to assess the situation. After a thorough investigation, BJ determined that what we had was an area in our crawl space that was emitting excess moisture to a particular area of the house, causing the floor to warp, and cause the floor to appear to rise. I was impressed with the conclusion, and especially happy that we weren't given some outlandish analysis that could have been in the thousands dollars to fix a seemingly easy situation.
