Wooden Fence Maintenance: Tips For Longevity

A well-maintained wooden fence adds charm, curb appeal, and privacy to your home. By protecting your wooden fence from UV rays, water, insects, and other sources of damage, you can improve its longevity. Wood fence maintenance isn’t too complicated, and you’ll be able to tackle most of the maintenance yourself. This guide will teach you how: 

Quick Maintenance Summary

  • Do a visual inspection of your fence every month.
  • Clean your fence at least once a year.
  • Keep vegetation near your fence trimmed.
  • Clear snow away from your fence.
  • Do physical inspections to check for structural problems.
  • Keep your fence sealed, resealing or repainting regularly.
  • Tighten loose fasteners, replace loose or damaged boards, and tackle other repairs as soon as possible.
  • Call a professional for major repairs. 

Understanding Common Threats To Wooden Fences

As an organic material, wood is subject to several threats that metal or vinyl fences are not. Your wooden fence can be affected by:

  • Rot and decay
  • Fungi, mould, and mildew
  • Insect infestations
  • Warping, splitting, and cracking

All of these concerns can be addressed through proper maintenance—and by using the right types of wood. The maintenance plan we outline below will help you prevent moisture from warping or rotting your wood, keep insects and fungus away, and keep your wooden fence sturdy for years to come. 

Routine Maintenance Checklist

Visual Inspections

A visual inspection is the best way to diagnose any problems with your fence. We recommend visual inspections twice a year; fall and spring are best to ensure that your fence is in great condition both before and after winter. There are a few things you should check for in your visual inspection:

  • Rotting or decaying wood. If you see any soft spots or discolouration in the wooden boards, it’s a sign of decay. You’ll want to replace the affected boards as soon as possible—though if you have many rotting boards or rotting fence posts, you may need professional help.
  • Cracks, splits, warping, and loose boards: Affected boards should be replaced as soon as possible.
  • Loose and rusty fasteners: Loose nails and screws can often be driven back in—unless they’re loose because the wood is warped or decayed. Rusty nails and screws should be replaced with weather-resistant fasteners.
  • Peeling paint: If your fence is painted, you’ll want to remove peeling paint and repaint the affected area to protect your fence from water damage. 
  • Leaning fence: Stand at one end of your fence, then look down the line. If everything looks straight and upright, you’re good to go—but if your fence appears to be leaning, your fence posts may be unstable. 

Cleaning Your Fence

Cleaning your fence does more than just boost curb appeal—it removes and halts the growth of mould and mildew and helps prevent wear and tear. Grime and debris can wear away at the protective surface of your wood fence, so regular cleanings are a must.

You can clean your fence using a garden hose and a scrub brush; for an even faster approach, use a pressure washer. Your pressure washer should be set at a relatively low PSI, about 1300 PSI for the most common hardwoods used in wood fencing, but even lower (500-800 PSI) if you’re washing a painted fence.

We recommend using a wide-tipped nozzle; a 25-degree or 40-degree tip is best because it will distribute the pressure along the fence. 

Test your pressure washer on a hidden part of your fence to ensure you’ve got the right pressure; start low and move up until you’re cleaning the fence without damaging the wood. By starting on a hidden part of your fence, you reduce the risk of doing visible damage if you accidentally use too high of a PSI. 

Trimming Nearby Vegetation

Trimming vegetation near your fence accomplishes a number of different things:

  • It lowers the risk of tree branches falling on your fence
  • It makes it more difficult for insects to climb your fence
  • It stops moisture from getting trapped by plants on your fence

By trimming grass, plants, and tree branches near your fence, you’ll get a better-looking, longer-lasting fence.

Checking For Structural Integrity

There are a few tests you can perform to check the stability and integrity of your fence. These tests include:

  • The push test: Push on a fence post or panel. If it flexes and then returns to its position, you don’t need to worry. If it leans and stays tilted, there may be wood rot, loose fasteners, or other problems.
  • The post stability test: Grab a fence post and wiggle the base. If it wiggles, the post is probably loose—either because of wood decay at the base or because of loose concrete footings.
  • Screwdriver test: Go to the soft-looking spots you saw during your visual inspection. Poke those spots with a screwdriver; if it crumbles or feels soft, there’s probably rot. 

Protecting Your Wooden Fence

You can improve your fence’s longevity with a few protective measures. The routine maintenance checks we just covered are one step—the next section will cover minor repairs. Before that, let’s talk about sealant:

The best way to protect your fence from decay, insects, warping, and more is to apply a protective sealant. Sealants stop water from penetrating into wood—that stops your fence from getting soft, which can also stop bugs from burrowing into it. High-quality sealants will also protect against damage from UV rays.

Your fence must be dry before you seal it; you can test this by dripping water onto your fence. If the water is absorbed quickly, your fence needs to be sealed—if the water beads, you won’t need to seal it right away.

When To Seal Your Fence

In many cases, your fence will be sealed when it’s installed—but if you’re using pressure-treated wood, the process is different. Sealing pressure-treated wood too early can actually trap moisture in your fence, causing rotting and warping. Most pressure-treated fences should be sealed 3 to 6 months after installation. Other wood fences should be sealed immediately.

You should reseal your fence every 2 to 3 years; it’s often a good idea to seal your fence after washing it. Be sure to stain your fence before sealing it.

When it comes to painted wooden fences, you don’t need sealant—the paint works to seal your fence. You should repaint every 5 to 10 years, spot-checking and painting when your paint starts to crack or peel.

Repairing Common Wooden Fence Issues

When your fence has significant damage, including post damage, you’ll want a professional to help. Outside of major damage, you may be able to handle minor repairs yourself; doing these repairs can help you prevent further deterioration in your fence. Some of the repairs you may be able to handle include:

  • Replacing fence boards (not fence posts)
  • Removing flaking paint and repainting your fence
  • Replacing rusty fasteners
  • Tightening loose fasteners
  • Replacing gate latches

You may also be able to tackle more complex repairs, like fixing a sagging gate—it all depends on your skill level. If you don’t feel confident in your ability to handle repairs, call a professional fencing contractor. 

Seasonal Wooden Fence Maintenance Tips

Spring And Summer

In the spring, you’ll want to inspect your fence to ensure there’s no damage from the winter. As the season goes on and spring turns to summer,  you can inspect for damage from insects, clean off mould and mildew, and trim vegetation around your fence. You’ll also want to check the stability of your posts after any storms.

Fall And Winter

In the fall, you want to take time to secure your fence before winter. Reseal your fence if it needs sealing. Rake away any leaves and debris near your fence, and make sure there’s no warping; you’ll also want to ensure that all fasteners, latches, and hinges are solid.

Winter is the worst season for fence maintenance, but there are still some tasks you can tackle—namely, keeping snow away from your fence. Shovel around your fence to stop moisture buildup! 

Year-Round Best Practices

We’ve already covered the best practices for fence maintenance—do a walk-around every month or two and follow the inspection checklist we covered at the beginning. You can also check for drainage issues around your fence. And always tackle fence repairs as soon as possible—repairing problems right away can help keep them from developing into something more serious. 

Conclusion

Wooden fence maintenance is well worth the effort—it can extend the lifespan of your fence, boost curb appeal, and keep your home private and secure.
