Adding floor jacks to correct Sagging Floors

Come with us into a very tight crawl space to correct some sagging floors. The builders of the addition didn't place posts or supports in the middle of the floor and simply spanned almost 19.' After a few years the floor was sagging down and the windows and doors didn't open and close. The walls were pulling off the ceiling. We went under and dug six footers and set six floor jacks. We had to use a steel beam due to the space constraints but made out fine with a 3x2x 1/4" rectangular tube. This beam far exceeded the 18,000 lb capacity of the floor jacks so we felt good about the repair.

If this had been new construction you wouldn't need six posts, but because the joists were already sagging and failing we needed that many to provide an even support to level things back out. We finished up with great success and the homeowner was very happy.

Setting these floor jacks on concrete, fastening them to the concrete and to the beam above is the correct way to provide permanent secondary support. This repair is permanent and will also pass inspection. Although very labor intensive and costly, in our opinion, it's the only way to go for a repair of this type.
