Mid Span Supports in Atlanta, GA
Why Long Spans Eventually Sag
Even if joists were properly sized at the time of construction, long, uninterrupted spans tend to deflect over years of use, especially under heavy furniture and modern loads. Wood naturally creeps under continuous stress, and any minor moisture issues or notching only accelerate the sagging. Mid span supports shorten those spans so joists no longer carry distance they can’t comfortably handle.
Options for Adding Mid Span Support
There are a few ways to introduce mid span support depending on the space below:
New Beam or Girder
Installed under joists, this beam runs across the span and takes a share of the load.
Support Posts and Footings
Columns beneath the beam transfer weight to newly poured pads or footings.
Supplemental Framing or Sistering
In some cases, additional joists are paired with existing ones and supported off the new beam for extra stiffness.
How Floors Above Improve After Mid Span Support
Once mid span support is added, homeowners usually notice:
Reduced floor bounce, especially in large rooms and hallways.
Fewer squeaks and creaks as joist movement is minimized.
Tiles, grout lines, and finishes becoming less prone to cracking.
A more “solid” feel underfoot that boosts confidence in the structure.
