What a Foundation Elevation Survey Actually Measures
The elevation survey is the foundation of every honest repair. Here’s exactly what we measure during a free inspection and what you get out of it.
The manometer
A digital manometer reads relative floor elevations across the home to ±1/8 inch, producing a contour map of high and low points — the objective picture of how your slab sits.
The report
You receive an elevation map, photos of the visible signs, and a plain recommendation — repair, monitor, or nothing needed. No scare tactics. Many surveys end in “monitor.”
Why it matters
Measurement replaces guesswork, which is how you avoid over-selling. It also sets a baseline to track movement over seasons — see seasonal movement.
