How to Fix Bouncy, Sagging Floors

If the floors in your home are bouncy, sagging or unlevel, they often point toward problems in your crawl space that fortunately can be fixed. Soft or uneven floors are not only a nuisance, but also most probably have you worried about how long the floors can support the weight of your house above.

Symptoms of Crawl Space Problems

To diagnose crawl space floor joist issues, take a walk around your living space and look for any areas where there is a gap between the floor and interior walls, namely where one clearly sees that the floor is sloping downwards. Also, check the interior walls for any cracks and any gaps around the door frames.

And don’t forget to note any doors that are sticking as you open and close them. *A tip is to also look at the bottom of the doors, and make sure the previous owners have not planed or ‘shaved-down’ the wood of the door to help it close. If this has happened, the floor will generally have arced scrape-marks on it where the door has struggled to be closed and opened.

Once the interior is covered, grab a flashlight and look under your house into your crawlspace. You are looking for any wood rot and deterioration of the floor joists. Because crawl spaces are often unsealed from groundwater seepage and wall moisture penetration, excess moisture and humidity are exposed to the wood joists which begin to rot, weaken and grow moldy. Weakened girders and floor joists are thus unable to continue supporting the weight above.

Also, check the distance between the existing block or brick columns – sometimes they are spaced too far apart from each other and the top beams become overloaded and sag between the columns. The girder sags with it, as does the floor above the girder.

And finally, check if any of the columns have a gap between the top of the column and the girder it was supporting. Here in Georgia, the weak, expansive soil often causes the existing columns to sink or settle, and once that happens the structural integrity can be compromised and floors sag.

*A tip for property buyers is to check the tops of those existing columns in the crawlspace for ‘shims’. These are thin wedges of wood or metal that have been driven into the crevices or gaps between the existing column and the girders in an attempt to level off the floor above. This is a temporary measure and further steps will have to be taken by the new homeowners to fix the sagging floor.
