What fails first here
- 1Green algae & mildewThe most common complaint about white vinyl. Moderate here: 86 rainy days a year, so mostly on north-facing panels. A garden-hose wash with mild soap removes it.
- 2Chalking & slight yellowingUV slowly breaks down the surface of PVC, leaving a dull, chalky film. UV here ranks #6 of 25.
- 3Sagging in heatAbout 123 days a year top 90 °F; long rails and gates can sag or bow if posts are too far apart.
- 4Cracks from cold impactsRare here: only about 11 freeze–thaw days a year.

How long does a vinyl fence last in Austin?
Our model puts a vinyl fence at 22–28 years in Austin (national typical range 20–30 yrs). It never rots; what ends its life is UV chalking, brittleness in cold and impact damage.
How often should you clean a vinyl fence in Austin?
Twice a year — in spring and fall. Dirt and pollen are the main thing to wash off.
Vinyl or wood fence: which lasts longer in Austin?
Our model gives a vinyl fence 22–28 years here and an untreated cedar fence 13–17 years. Vinyl needs washing instead of staining, and it does not rot at the posts.
Why does a white vinyl fence turn green in Austin?
The green film is algae and mildew growing on dirt and pollen that sit on the surface, mostly on the shady side and near the ground. It does not damage PVC; a wash with water and mild soap (or a vinyl cleaner) removes it.
