When homeowners invest in a new cedar fence, they want to know it's going to hold up. The good news: a properly installed Western Red Cedar fence can last 20 to 30 years in Colorado's climate — and sometimes even longer with basic care.
Cedar contains natural oils called thujaplicins that make it resistant to rot, decay, and insect damage without any chemical treatment. That's a huge advantage over pressure-treated pine, which relies on chemical preservatives that can break down over time — especially in Colorado's intense UV and dramatic temperature swings.
Pine fences in our area typically show significant warping and cracking within 7–10 years. Cedar, by comparison, stays dimensionally stable and weathers gracefully.
Several factors specific to Northern Colorado influence how long your cedar fence will last:
Installation quality is the single biggest factor. Posts set deep enough (at least 30–36 inches in our soil), proper drainage at the base, and rails that are level and secure all contribute to a fence that lasts decades, not just years. This is where working with experienced fence contractors makes a real difference.
Soil contact is the enemy of any wood fence. We set posts in concrete and keep the bottom of fence boards slightly above ground level to prevent moisture wicking. It's a small detail that adds years of life.
Sun exposure is intense at our elevation. South and west-facing fences take the most UV punishment. Cedar handles it well — it silvers gracefully — but a quality stain or sealant can extend its life further if you prefer the warm golden color.
Cedar is about as low-maintenance as wood fencing gets. For most homeowners, the only maintenance needed is an occasional rinse with a garden hose and an optional stain or sealant every 3–5 years. No painting. No chemical treatments. No annual re-staining unless you want to.
The bottom line: cedar is a long-term investment that pays for itself in durability, beauty, and peace of mind.
