How to Maintain a Cedar Fence: What Homeowners Should Know

What to Know About Cedar Fence Maintenance

• Natural Changes Are Expected: Checking in solid posts, gaps between boards, rough texture, and color variation are normal characteristics of cedar.
• Control Excess Moisture: Keep sprinklers, soil, mulch, vines, and branches from holding moisture against the wood.
• Clean Gently: Avoid aggressive cleaning that can damage the rough-sawn surface.
• Staining Is a Choice: You can let cedar weather to silver-gray or apply a finish if you prefer to retain its warmer color.

Your cedar fence will change as it ages. Posts may develop checks, boards may shrink, and the warm cedar color will gradually weather. Knowing how to maintain a cedar fence starts with understanding what's normal and what needs attention.

In this guide, we'll walk you through what to expect as your cedar fence ages and the simple steps you can take to care for your fence.

What Changes Are Normal for a Cedar Fence?

Real cedar changes as it dries and reacts to Illinois weather, so some variation is expected.

Your Posts May Crack: That’s Called Checking

A solid cedar post dries from the outside in, which can create a split along the grain called a check. Checking is normal in posts, post caps, finials, and picket tops. These checks may open during dry weather and tighten as humidity rises.

A check along the grain does not mean the post has failed. But you should schedule fence repair if a post, rail, or board cracks all the way through, breaks, or starts to come loose.

Rough-Sawn Cedar Is Not Cabinet Lumber

At Cedar Mountain Fence Company, we make our cedar fences from rough-sawn northern white cedar boards, so expect natural variation in the saw-cut texture, including raised grain, saw marks, knots, and slight thickness differences. Full-dimension posts may also have rounded edges, natural curves, or an occasional bark edge.

Gaps May Open as the Boards Dry

Cedar boards still carry moisture when we install them. As they dry and shrink across the grain, gaps can begin to appear between boards, especially during the first three to twelve months.

Those gaps also change with the seasons. Boards can swell during humid weather and shrink when conditions are drier, while slight cupping or bowing can occur as the wood moves. Your privacy fence will still block sight lines, but some daylight between boards is normal once they dry.

Expect Natural Color and Grain Variation

Cedar boards naturally vary in color, grain, knots, and mineral streaks, so some may look reddish-brown while others are much lighter. A new fence can look patchy at first, but sunlight and weathering help even out the overall appearance.

Cedar Turns Gray, and That Is Fine

Left unfinished, your cedar gradually changes from its warmer honey-tan color to silver-gray, typically over roughly one to two years. This change is normal and doesn't mean the wood is rotting.

You can let your fence weather naturally or stain it to help retain its warmer color. Either way, proper care plays a role in how long a wood fence lasts.

How to Care for a Cedar Fence

Cedar fence maintenance is fairly simple. A few practical habits can help you care for the wood as it ages:

• Keep Sprinklers Away From the Fence: Repeated irrigation keeps cedar wet longer than necessary. Adjust your sprinkler heads so they aren't regularly spraying the fence.
• Clear Soil and Mulch From the Boards: Soil and mulch hold moisture against wood. Pull them back from the bottom of your fence so the cedar has room to dry.
• Trim Vegetation Along the Fence Line: Keep vines and branches off the fence so the cedar can dry after rain, and you can easily spot problems along the fence line.
• Clean Cedar Gently: Too much pressure can tear into the rough-sawn wood fibers. For lighter buildup, we recommend mild detergent with a soft brush or cloth.

Should You Seal or Stain a Cedar Fence?

You can let your cedar weather naturally to silver-gray or apply a finish if you want to retain more of its warm color.

If you choose a stain or another exterior wood finish, let the wood dry adequately and follow the manufacturer's directions for preparation and application. Your product and fence exposure will determine when recoating is needed.
