Sagging Floor Repair Services in Knoxville TN



This repair consists of 4″ x 4″ or 6″ x 6″ treated posts that run perpendicular to the floor joists, with adjustable floor jacks on solid 8″ blocks or 24″ x 24″ x 8″ concrete footers.

This system allows us to adjust and level sagging floors at affordable cost to the homeowner.

These jacks have a 9,000 – 18,000 lbs. capacity based on the adjusted setting


Over time, the structural supports or load bearing areas may begin to sink into the ground or the wood begins to rot. It may also be discovered there were too few supports to begin with.

For maximum girder supports, Guardian Foundation Repair recommends:

  • A double stacked 8 inch block column with solid 4 inch cap blocks. These blocks are constructed on a 30″ x 30″ x 8″ footer on 6 foot centers.
  • For less load bearing areas such as porches and sunrooms we offer a single stacked 8 inch block column
