Subfloor & Joist Repair in Columbia, TN
Sister, replace or re-support framing that a wet crawl space has already damaged.
A crawl space that stayed wet long enough leaves evidence in the framing above it: joist ends soft where they sit on the sill, girders sagging between piers, subfloor delaminating so the floor above feels spongy underfoot. Sistering a new member alongside the old one, replacing a section outright, or adding a pier to shorten a span are the usual repairs.
In the older parts of town this often runs into stone or rubble piers that have settled unevenly over a century, which changes how a repair gets supported and is worth knowing before anyone quotes it. A bouncing floor is not always rot. Sometimes it is a span that was always too long and only became noticeable when the floor covering changed.
Typical cost: $1,200 - $8,000 depending on how many members are affected and how bad the access is

When subfloor and joist repair is the right call
- A floor that feels soft, springy or bouncy in one area
- Doors upstairs that have started sticking on one side of the house
- Visible sag in a girder line, or a pier that has shifted off plumb
- Soft or crumbling wood where joists meet the sill plate

Common questions
Do I fix the framing or the moisture first?
Diagnose together, then fix the water first wherever the schedule allows. New wood put into a wet space starts the same clock the old wood already ran out.
Is sistering as good as replacing?
For a joist damaged at one end, a properly sized and fastened sister carries the load and costs far less than pulling the floor up. Replacement wins when the member is gone along its length or when several in a row are affected.
