Post & Pier Foundation Repair, Stop the Sag, Strengthen the Structure
[ 01 ] The Honest Answer
What you should know about post & pier foundation repair
What Is a Post and Pier Foundation?
Many Middle Tennessee homes built before the 1970s, and some newer construction on sloped lots, use a post-and-pier foundation system. Rather than a continuous perimeter wall, the structure rests on a grid of individual piers (concrete columns or block stacks) with wood posts on top supporting the beams and floor framing above. When it works, it is an economical and effective foundation type. When it fails, you feel it every time you walk across the floor.
Post-and-pier foundations fail for several predictable reasons in Middle Tennessee. Wood posts that were set directly on block or concrete piers without metal standoffs absorb ground moisture and rot from the bottom up. Block piers that were set in shallow soil settle unevenly as clay soils move through wet and dry seasons. Piers that were spaced too widely for the spans above them allow beams to sag over time. In all of these cases, the result is floors that bounce, slope, or have visible dips at the center of spans.
What We Do
- Pier replacement: removing failed block or concrete piers and replacing them with new concrete piers at correct height and bearing
- Adjustable steel column installation: replacing wood posts with adjustable steel columns that can be fine-tuned for level and do not rot
- Helical pier underpinning: for piers that are settling in poor soil, driven helical piers beneath the existing pier provide permanent deep bearing
- Beam sistering: reinforcing sagging beams alongside existing framing to restore the span capacity

[ 02 ] How It Works
What to expect, start to finish
Crawl Space Inspection
We enter the crawl space, photograph conditions, measure floor levels, and assess every pier and post for condition, height, and stability.
Repair Plan
We identify which piers need replacement or underpinning, which posts should be upgraded to steel columns, and whether any beam sistering is needed.
Pier and Post Work
Failed piers are removed and replaced. Posts are upgraded to adjustable steel columns. Helical piers are installed where soil conditions require deep bearing.
Level Adjustment
Adjustable columns are fine-tuned for level before final lock-off.
Documentation and Walkthrough
We document all work completed in the crawl space and walk you through the results at grade.
Post-and-pier foundation work is crawl space work, and a lot of contractors avoid it. We go in, document exactly what we find, and come back out with a clear plan. Homeowners appreciate that there are no surprises.
