Fencing · Hot & dry

How long does a vinyl fence last in Los Angeles, CA?

THE SHORT ANSWER

In Los Angeles, sun is the main stress on a vinyl fence: UV ranks #5 of 25 cities we cover and there are about 26 days above 90 °F. White PVC slowly chalks and can yellow slightly on the sunny side; in very hot sun, long panels and rails can sag if they were installed without expansion room. Model estimate: 22–29 years of service.

What fails first here

  1. 1Chalking & slight yellowingUV slowly breaks down the surface of PVC, leaving a dull, chalky film. UV here ranks #5 of 25.
  2. 2Green algae & mildewThe most common complaint about white vinyl. Moderate here: 34 rainy days a year, so mostly on north-facing panels. A garden-hose wash with mild soap removes it.
  3. 3Sagging in heatOnly about 26 days a year top 90 °F, so heat sag is unlikely.
  4. 4Cracks from cold impactsRare here: only about 0 freeze–thaw days a year.

Questions Los Angeles owners ask

How long does a vinyl fence last in Los Angeles?

Our model puts a vinyl fence at 22–29 years in Los Angeles (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 Los Angeles?

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 Los Angeles?

Our model gives a vinyl fence 22–29 years here and an untreated cedar fence 16–21 years. Vinyl needs washing instead of staining, and it does not rot at the posts.

Why does a white vinyl fence turn green in Los Angeles?

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.
