We had a structural engineer check our 100 year old house and he said to level the house and replace some of the floor joists that were starting to deteriorate from the moisture in the crawl space. When there is a heavy rain water enters the crawl space but leaves quickly.
Our house was moved to it's present location and over the years it has settled. We have had two contractors look at the house. One contractor is going to use steel I-Beams and support posts to level the floors and the other contractor is going to use engineered wood beams and support post to level the floors. The crawl space is four feet tall. Which method would be the best.
