What goes wrong for retaining wall.
Symptoms first, quotes second
Most expensive retaining wall mistakes start with a symptom described to a salesperson. The table maps the common symptoms to their usual cause — the diagnosis a contractor should confirm before quoting.
| Symptom | Usual cause |
|---|---|
| Leaning wall | Hydrostatic pressure |
| Bulging | Backfill and drainage |
| Settlement | Footing too shallow |
| Weeping face | No drain or filter fabric |
| Root damage | Trees too close |
What to document
- Photographs with something for scale, taken at the same angle over time.
- Dates: when it started, whether it changes with weather.
- Water: where it goes, where it pools, what it damages.
- Previous work: who did it, when, and with what material.
What not to do first
Do not accept a repair scope before the cause is named. Patching a symptom is how the same problem returns next season with a bigger invoice. The methods hub explains what each fix addresses; the cost hub shows what it should cost.
When is it an emergency?
When water is entering the structure, when something is structurally unstable, or when a safety system has failed. Everything else can wait for a second opinion.
Should I get an independent inspection?
For anything structural or over about $5,000, yes. A few hundred dollars for an independent report is cheaper than a wrong scope.
