Thinking about installing a cedar split rail fence? It’s a classic choice that brings a natural, rustic charm to any property. But before jumping in, many homeowners wonder how long this type of fence will actually last. If you’re working with a trusted fence company, you’ll likely get honest advice about what to expect in terms of longevity and how to make your fence last as long as possible.
Let’s take a closer look at what you can expect from a cedar split rail fence and how to get the most out of your investment.
Cedar Is Naturally Durable
Cedar is one of the best woods for outdoor use, thanks to its natural resistance to insects, rot, and moisture. This makes it an ideal material for split rail fences, especially in areas that experience a wide range of weather conditions. Compared to pine or spruce, cedar holds up better and doesn’t need as much chemical treatment to stay strong.
On average, a cedar split rail fence can last anywhere from 15 to 30 years. The exact lifespan depends on a few important things, like the local climate, soil drainage, and how well the fence is maintained over time. With a little care, cedar fencing can stay strong and sturdy for decades.
Factors That Affect Fence Lifespan
Even though cedar is naturally tough, it’s still important to protect it from the elements. Some of the most common reasons cedar fences wear out sooner than expected include:
- Poor drainage: Wet, heavy soils—especially clay—hold onto moisture. If posts sit in water for too long, they’ll rot much faster.
- Ground contact: When pickets or rails touch the ground or dense plants, moisture stays trapped, which can lead to decay.
- Sun exposure: Constant sun can dry out the wood and cause cracking or warping over time.
By taking a few precautions during installation, many of these issues can be avoided.
Proper Installation Is Key
How you install a cedar fence plays a big role in how long it lasts. A trusted fence company will know the best techniques to prevent future problems and extend the life of the fence. Here are a few smart tips:
- Use gravel in post holes: Instead of packing the posts in with dirt or concrete, gravel allows better water drainage and helps keep the wood dry.
- Set posts deep: Digging post holes at least 36 inches deep helps anchor the fence securely and keeps it upright through harsh weather.
- Choose thick rails: Using jumbo-size rails and limiting rail length to 8 feet instead of 10 helps prevent sagging.
Installing the fence with care upfront will save time, money, and headaches later on.
Should You Stain or Seal Cedar?
While cedar naturally weathers to a soft silver-gray, some homeowners choose to apply a sealant or stain to protect the wood and keep its rich color longer. Though it’s not required, sealing your fence every couple of years can help it resist moisture, UV rays, and mildew buildup.
Regular maintenance like staining, cleaning, and checking for loose rails can go a long way in preserving your fence. The more attention you give it, the better it will perform in the long run.
Preventing Fence Rail Sag
One of the most common issues with split rail fences is sagging rails over time. This usually happens when rails are too long or too thin to hold their shape. To avoid this:
- Use thicker rails (jumbo-grade cedar is a great option)
- Stick with 8-foot rails for better support
- Make sure posts are evenly spaced and properly installed
When done right, your fence will remain straight and sturdy with little to no sagging for many years.
Final Thoughts
Cedar split rail fences are strong, attractive, and built to last—especially when installed and maintained the right way. With proper materials, thoughtful installation, and basic upkeep, you can expect your cedar fence to last anywhere from 15 to 30 years.
Working with a trusted fence company ensures your fence is built with care and precision from the start. Whether you’re fencing in a large property or just marking off a section of yard, a cedar split rail fence is a timeless choice that offers long-term value.
