Fencing · Cold, hard freeze–thaw
How long does a vinyl fence last in Denver, CO?
In Denver, cold is the main stress on a vinyl fence: about 135 days a year cross the freezing point (#1 of 25 cities we cover). PVC gets brittle in hard cold, so a ball, a snow shovel or blown debris can crack a panel or rail in winter that would only bounce off in summer. Model estimate: 20–26 years of service.

What fails first here
- 1Cracks from cold impactsAbout 135 freeze–thaw days a year: PVC is brittle below freezing, so winter knocks crack panels and rails.
- 2Chalking & slight yellowingUV slowly breaks down the surface of PVC, leaving a dull, chalky film. UV here ranks #14 of 25.
- 3Green algae & mildewThe most common complaint about white vinyl. Moderate here: 84 rainy days a year, so mostly on north-facing panels. A garden-hose wash with mild soap removes it.
- 4Sagging in heatAbout 42 days a year top 90 °F; long rails and gates can sag or bow if posts are too far apart.

How long does a vinyl fence last in Denver?
Our model puts a vinyl fence at 20–26 years in Denver (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 Denver?
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 Denver?
Our model gives a vinyl fence 20–26 years here and an untreated cedar fence 13–17 years. Hard winters are vinyl’s weak spot (brittle panels), but it still outlasts wood that is never stained.
Why does a white vinyl fence turn green in Denver?
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.
