How do you level a sagging floor?

Answer by  AnnaTeague (806)

Before removing flooring and sub-floors, get into the crawl space and inspect the joists for breakage, cracking, termite damage, and adequate size and spacing. Often inadequate or damaged joists can be "sistered" with new joists attached on either side. 2"X10" joists would be recommended. Also, add metal braces.

In order to level a sagging kitchen floor you have to open the floor and install wooden planks underneath. But if you want a permanent solution you should probably hire a professional.

Unfortuntately, this must be done professionally. It's hard to tell why one area of a house may be sagging. The problem may actually be in a different part of the house, so you need to get a contractor to look at the problem and give you an estimate on leveling your foundation.

You should hire a professional to look at the problem. You likely have a pier and beam construction dwelling and the floor joists may not be doing their job. This is not something you should take on if you don't have experience.

If you have a basement you will need to go into the basement and use leveling posts on the joists. If not you will need to remove the flooring and shim up the sagging areas.
