Rust Removal from AC Drip Pan Leaks in Houston, TX
If you’ve ever noticed orange or brown streaks running down your siding, trim, or brick, there’s a good chance your AC drip pan or condensate line is the culprit. This Houston-area home had visible rust staining caused by ongoing AC drainage, leaving the exterior looking worn and neglected.
Rust stains from air conditioning systems are extremely common in Houston, especially during long cooling seasons when AC units run almost nonstop. The good news? These stains can often be removed safely — if treated correctly and early.

What Causes Rust Stains from AC Drip Lines?
Air conditioning systems produce condensation. Over time, that moisture can:
- Carry iron and minerals from the drip pan or fittings
- Run repeatedly down siding or trim
- Oxidize and create rust stains on exterior surfaces
These stains often appear on:
- Hardie plank or fiber cement siding
- Painted siding and trim
- Brick and stone accents
Once rust sets in, regular pressure washing alone will not remove it.
Why Rust Stains Need Specialized Treatment
Rust is not dirt — it’s a chemical reaction. Using high pressure or harsh methods can actually set the stain deeper or damage the surface.
For this home, we used a professional rust removal treatment specifically designed to break down iron oxidation safely. This process:
- Lifts rust without damaging siding
- Restores the original color of the surface
- Prevents unnecessary repainting
- Protects surrounding materials
The before-and-after difference speaks for itself.
