Cedar fencing represents a significant investment in your property's beauty, privacy, and value. The natural oils that make cedar rot-resistant also give it that beautiful warm color. Without proper maintenance, however, cedar weathers to silver-gray and becomes vulnerable to the elements. Understanding cedar's unique properties helps you maintain its beauty for generations.
Why Cedar?
Western Red Cedar has earned its reputation as the premium fencing material for good reasons. Its natural properties make it ideal for outdoor use in Canadian climates.
Natural Rot Resistance
Cedar contains thujaplicins—natural compounds that resist fungi, bacteria, and decay. This built-in protection means cedar requires no chemical treatment yet outlasts many treated woods.
Dimensional Stability
Cedar shrinks and swells less than other woods as moisture levels change. This stability means fewer warped boards, loose fasteners, and structural problems over time.
Beautiful Appearance
Fresh cedar displays warm reddish-brown tones with attractive grain patterns. Even weathered gray cedar has a dignified, natural appearance many homeowners prefer.
Lightweight Strength
Cedar offers excellent strength-to-weight ratio, making installation easier while maintaining structural integrity. This property also makes repairs more manageable.
First-Year Care
How you treat cedar in its first year sets the stage for decades of performance. Proper initial care maximizes your investment.
The Waiting Period
New cedar needs 60-90 days to weather before sealing. This allows surface oils to dissipate and wood cells to open for better finish penetration. Sealing immediately traps moisture and surface oils, causing adhesion problems.
Initial Cleaning
After the waiting period, clean your fence with oxygen bleach solution to remove any mildew, construction dirt, or handling marks. Rinse thoroughly and allow complete drying (another 48-72 hours).
First Application
Apply a quality penetrating oil or semi-transparent stain designed for cedar. Penetrating finishes work with cedar's properties rather than forming a film on the surface. Apply generously, allowing the wood to absorb as much as possible.
Annual Maintenance Schedule
Consistent annual maintenance prevents major problems and maintains appearance. This schedule keeps cedar fences in optimal condition.
Spring Inspection (March-April)
- Walk the entire fence line checking for winter damage
- Note loose boards, damaged posts, or leaning sections
- Look for mildew growth (common after wet winters)
- Check gate hardware and hinges
- Schedule repairs before summer enjoyment
Summer Cleaning (May-June)
- Clean with oxygen bleach solution
- Address mildew with appropriate treatment
- Complete any necessary repairs
- Allow thorough drying
Fall Protection (September-October)
- Apply fresh finish if needed (2-3 year intervals)
- Clear vegetation from fence line
- Ensure drainage directs water away from posts
- Trim tree branches that contact fence
Cleaning Methods
Proper cleaning removes damaging substances without harming wood or existing finish.
Light Cleaning
For general dirt and dust, use a garden hose with moderate pressure. Work from top to bottom in sections. This works well for maintained fences between deep cleanings.
Oxygen Bleach Cleaning
Mix oxygen bleach powder with water according to directions. Apply with pump sprayer, scrub with soft brush, allow 10-15 minutes contact time, rinse thoroughly. Safe for plants and effective on mildew.
Power Washing
Use 500-800 PSI maximum with a 25-40 degree nozzle. Hold 12-18 inches from surface at a 45-degree angle. Move with the grain in smooth strokes. Power washing is effective but requires careful technique to avoid damage.
Sealing vs. Staining
Understanding the difference between sealers and stains helps you choose the right protection for your goals.
Clear Sealers
Clear sealers protect against moisture while preserving cedar's natural color. They provide minimal UV protection, so cedar will eventually gray even when sealed. Reapply annually for best results.
Semi-Transparent Stains
These products add color while showing wood grain. They provide better UV protection than clear sealers, slowing the graying process. Reapply every 2-3 years. Most popular choice for cedar fences.
Solid Stains
Solid stains hide wood grain completely but provide maximum UV and moisture protection. They work well for older fences with imperfections to hide. Expect 4-5 years between applications.
Common Repairs
Addressing minor issues promptly prevents major problems. Most cedar fence repairs are straightforward.
Loose Boards
Refasten with stainless steel or hot-dipped galvanized screws. Regular nails often loosen as wood moves seasonally. Pre-drill to prevent splitting on old, dry cedar.
Leaning Posts
For minor lean, add bracing or sister a new post alongside. Severely rotted posts require excavation and replacement with proper concrete footing.
Split Boards
Minor end splits can be stabilized with stainless steel screws. Significant splits or cracks warrant board replacement. Match new cedar species and grade for best appearance.
Frequently Asked Questions
How soon after installation should I seal cedar?
Wait 2-3 months for new cedar to weather slightly and surface oils to dissipate. Sealing immediately can trap moisture and prevent proper penetration. The wood should be clean and dry before applying any finish.
Should I let cedar go gray naturally?
That's a personal choice. Natural gray cedar has rustic appeal and requires minimal maintenance. However, the gray surface is partially degraded wood fiber that slowly erodes. Sealed cedar maintains its appearance longer.
How do I match new cedar boards to existing weathered fence?
New cedar will stand out against weathered wood. Options include letting it weather naturally (takes 6-12 months), applying gray stain to new boards, or refinishing the entire fence for uniform appearance.
What's eating my cedar fence?
Cedar's natural oils resist most insects, but carpenter bees and some beetles can attack. Look for round holes (carpenter bees) or fine sawdust (beetles). Treatment and sealing help prevent infestation.
