We have a 23 year old house in the Houston Texas area with a slab foundation. It definitely needs repair and we are in the process of getting bids from repair companies. One of our neighbors used one of the same companies that we are considering and when asked how satisfied they were with the company's work, the response was negative, due to the fact that they still had some doors that weren't working properly. This particular company has a very good BBB rating and we were surprised to hear such negative comments.We wonder if our neighbor had unrealistic expectations. Our question is: what should we expect in terms of results from a slab foundation repair?? Thanks.
