Sagging Floors… a Sign of Foundation Damage

Published by Leave your thoughts
There are people who consider a sagging floor within an older house to be part of it’s historical charm. The unfortunate truth is that sags in floors will negatively impact the safety, convenience and property value of the home.

What to Look For

When a floor is sagging, unsightly gaps will appear between the floor and the baseboard moldings. If the joists are sagging your furniture won’t rest evenly on the floor. This forces homeowners to use shims to prevent tables and chairs from wobbling. In addition to sagging, some floors will also feel springy or bouncy under your foot.

Common Causes of Sagging Floors

When a house is built, the floors are flat and level. If a floor starts to sag over time then the home most likely has structural problems. If you notice sagging floor in your home call Foundation Technology, right away. One of our foundation repair specialist will come out to your home free of charge to determine which of the below issues caused your floor to sag.
  • Settled Foundation Wall
    When a floor sags on one side of a house rather than the center; then the foundation on that sagging side has settled. This is because the floor joists that extend across the width of the house bear directly on foundation walls. When the foundation begins to settle, the floors will sag.
  • Damaged Posts
    The majority of homes with basements or crawl space foundations have floor joists that extend across the width of the house. These joists are supported by a central beam. That beam itself is then supported by a series of posts. If one of these posts rots, shifts or settles, the central beam will lose its support. As a result, the beam sags and may also become springy from the weight of the floor, people and furnishings above.
  • Inadequate Support for the Central Beam
    Although the posts supporting the central beam are in good condition, if they are spaced too far apart then the floors will begin to sag. The central beam would then be undersized and have to span too long a distance between the posts.
