Cedar is one of the most admired fencing materials in the U.S. Its warm tones, rich grain, and natural resistance to rot make it a favorite for homeowners who want both beauty and durability. However, even with its impressive qualities, cedar is not invincible. Without the right care, cedar fences can lose their vibrant color, suffer from moisture damage, and become vulnerable to pests.
That’s where cedar fence sealers come in especially natural options that protect without relying on harsh chemicals. If you’ve invested in a cedar fence, understanding why it needs special protection will help you keep it strong and beautiful for years to come.
What Makes Cedar a Popular Fencing Choice
Cedar has earned its place as a premium fencing material for several reasons:
-
Natural resistance to decay and insects – Thanks to naturally occurring oils, cedar resists rot better than many other woods.
-
Aesthetic appeal – Cedar’s reddish-brown hue and distinctive grain give it a timeless look.
-
Longer lifespan compared to untreated softwoods – Cedar can last decades if cared for properly.
-
Sustainability – Sourced from managed forests, cedar is a renewable building resource.
Still, even with these qualities, cedar is not maintenance-free. Weather, sun, and biological growth can slowly wear it down.
Why Cedar Needs Extra Protection Despite Its Durability
While cedar has built-in defenses, it’s not immune to the elements.
UV Damage and Fading Colors
The sun’s ultraviolet rays break down the fibers in cedar over time. This causes the color to fade from warm reds and golds to a dull gray. While some homeowners like the weathered look, many prefer to maintain cedar’s natural vibrancy.
Moisture and Water Penetration
Cedar absorbs water if left unsealed. Repeated cycles of soaking and drying can cause swelling, shrinking, warping, and cracking.
Mold, Mildew, and Fungus Growth
In humid or shaded areas, unprotected cedar can develop mold or mildew. This not only affects appearance but can also weaken the wood’s structure.
How Cedar Fence Sealers Work
A cedar fence sealer acts like a protective shield.
-
Water Repellency – It prevents water from soaking into the wood.
-
UV Protection – Many sealers contain additives that slow down sun damage.
-
Fungal Resistance – Some sealers include anti-fungal agents to prevent mold and mildew growth.
-
Extended Lifespan – Sealing regularly keeps the fence stronger for longer.
The Benefits of Using a Natural Cedar Fence Sealer
Chemical-based sealers can get the job done, but they often come with strong fumes and potential environmental hazards. A natural cedar fence sealer offers a safer, more eco-friendly approach.
Key advantages include:
-
Safe for children and pets playing near the fence
-
No harmful volatile organic compounds (VOCs)
-
Supports a healthier environment by avoiding toxic runoff
-
Compatible with cedar’s natural properties, preventing chemical breakdown of the wood
Why Cedarwood Oil is the Perfect Partner for Cedar Fence Protection
Cedarwood oil is more than just a pleasant-smelling essential oil it’s a natural defense mechanism that complements cedar’s own properties.
Natural Insect Repellent Properties
Cedarwood oil disrupts insect pheromones, making it harder for pests like ants, moths, and termites to locate the wood.
Anti-Fungal Benefits
It contains compounds that help prevent mold, mildew, and fungal growth, which can stain or damage the wood.
Long-Term Savings
By combining sealing with pest deterrence, cedarwood oil reduces the need for costly repairs or early replacement.
Steps to Properly Seal a Cedar Fence
Sealing a cedar fence isn’t difficult, but doing it correctly makes all the difference.
-
Clean the Fence
-
Remove dirt, dust, and any algae or mildew using a mild cleaner or a wood-safe pressure wash.
-
Allow It to Dry
-
Make sure the wood is completely dry before applying sealer. Moisture trapped under the sealer can cause problems later.
-
Apply the Sealer Evenly
-
Use a brush, roller, or sprayer to cover the wood thoroughly. Pay attention to edges and joints.
-
Reapply as Needed
-
Depending on climate, reapply every 2–3 years or as recommended by the product manufacturer.
Mistakes to Avoid When Sealing Cedar
Even well-intentioned DIY sealing jobs can go wrong. Here’s what to watch out for:
-
Using the Wrong Sealer – Avoid products not formulated for cedar or outdoor use.
-
Skipping Prep Work – Sealing over dirt, mildew, or moisture will trap problems inside.
-
Over-Applying – Too much product can cause sticky surfaces or uneven absorption.
-
Waiting Too Long to Re-Seal – Once cedar starts to fade or crack, sealing is less effective.
Cedar Fence Maintenance Tips for Long-Lasting Protection
Consistent care ensures your cedar fence stays strong and attractive.
-
Inspect the fence twice a year for signs of wear, warping, or discoloration
-
Clean it regularly to prevent dirt buildup and mold growth
-
Apply touch-up sealant to high-wear spots like gates or posts near sprinklers
-
Keep plants and soil from directly contacting the fence to avoid moisture trapping
