Cedar Fence Installation in Anchorage, Alaska

Not every wood species can handle what Alaska dishes out. From January lows of -30°F to summer highs pushing past 70°F, your fence endures a 100-degree temperature swing every single year. That relentless freeze-thaw cycle cracks, warps, and splits most lumber within a few seasons. Western red cedar is the exception.

Cedar's secret lies in its cellular structure. The wood is loaded with natural oils and extractives — primarily thujaplicins and thujic acid — that act as built-in preservatives. These compounds repel moisture, resist fungal decay, and deter wood-boring insects like carpenter ants and beetles, all without the chemical pressure-treatment that other species require. That means no arsenic, no chromium, no copper leaching into your soil near gardens and play areas.

The tight, straight grain of Western red cedar also gives it exceptional dimensional stability. While pressure-treated spruce and pine twist and cup as they absorb and release moisture through Alaska's seasons, cedar holds its shape. Boards stay flat. Joints stay tight. Your fence looks as good in year ten as it did the week we built it.

• Natural rot resistance — thujaplicin oils protect against decay without chemical treatment
• Insect deterrent — aromatic oils repel carpenter ants, beetles, and termites naturally
• Dimensional stability — tight grain resists warping, cupping, and splitting in freeze-thaw cycles
• Thermal performance — handles 100+ degree annual temperature swings without cracking
• Beautiful aging — weathers to an elegant silver-gray or maintains warm tones with sealant
• Sustainable material — renewable, biodegradable, and harvested from managed Pacific Northwest forests
• Lightweight yet strong — easier to work with during Alaska's short building season

Left untreated, cedar gracefully darkens to a distinguished silver-gray patina that blends beautifully with Alaska's natural landscape. Prefer to keep the warm reddish-brown tones? A quality oil-based sealant applied every two to three years during summer preserves the original color for decades.

Spring (April – May)

Spring is inspection season. Walk your entire fence line and look for frost heave damage — posts that have lifted or tilted over winter. Check every post for stability by pushing firmly at the top. If a post rocks, it likely needs to be re-set below the frost line. Clean any green mildew or algae with a diluted oxygen bleach solution (not chlorine bleach, which damages cedar fibers). Rinse with a garden hose — never a pressure washer, which gouges the soft cedar grain.

Summer (June – August)

This is your only staining window. Alaska gives you roughly three months when temperatures stay consistently above 50°F, which is the minimum for oil-based stain to cure properly. Apply a UV-resistant, semi-transparent penetrating stain to all exposed cedar surfaces. Pay special attention to end grain on the tops of pickets and posts, where moisture wicks in fastest. Stain every 2 to 3 years to maintain color and protection.

Fall (September – October)

Before the first hard freeze, tighten any loose fasteners and replace boards that have cracked or split. Clear leaves, brush, and debris from the base of the fence line — trapped moisture against the bottom rail accelerates rot. Trim back any vegetation growing against the fence. This is also a good time to verify that gate latches operate smoothly before ice and snow complicate adjustments.

Winter (November – March)

Monitor snow accumulation along the fence. The single most damaging thing homeowners do to their cedar fences in Alaska is pile plowed snow against them. That concentrated weight bows panels, snaps rails, and pushes posts out of plumb. Direct your snow removal away from the fence line. If heavy wet snow builds up naturally, knock it free with a broom before it freezes solid against the wood.
