I purchased my home one year ago and now I am starting to notice some sloping on the first floor and the second floors are very bouncy. Who would be the best person to contact about this situation. A contractor, home inspector or someone else??
If you know some good reputable contractors you could ask their opinion. I would recommend a structural engineer who works with home problems since your description indicates some structural defect. If this is a newer home then it could have been a design problem. On an older home it could also involve insect or water damage. Regardless, please take care of this problem right away to prevent even more damage.
