How to Weatherproof Your Wood Fence

As you already know, the harsh weather in Minnesota wears away at your home's exterior rapidly. Your wood fence isn't an exception. With bitterly cold and snowy winters, brutally hot summers, and unpredictable spring and fall seasons, the elements will begin to break down any part of your fence.

Luckily, there's a way to combat Mother Nature's entropy. Here's how to weatherproof your wood fence!

Bolster Weak Points

Sooner or later, your wood fence will show some wear in weak areas. Signs of weak spots include loose nails or screws, rotting wood planks or pickets, and damaged posts. 

Hammer in loose nails, drive in extra screws in weaker joints, and replace rotting wood as you see it to guarantee a strong and sturdy fence!

Clear Away Debris

When leaves and other organic materials fall on your fence and stay there, the more likely wood will rot under constant moisture. To prevent this from happening, be sure to inspect and clean off any debris, mold, and algae from the surface. 

You may have to get the ladder out for those tall privacy fences!

Secure Loose Items

From lounge chairs to umbrellas, it's not uncommon to have an array of items stored in the yard during the summer months. These become problematic when heavy winds set in because the loose objects can turn into projectiles.

Putting any belongings away before winter storms take hold or securing them if you know a storm is en route is another way to keep your fence system safer.

Waterproof Your Wood Fence: 4 Methods

Applying a waterproof sealant to your wood fence is prudent to fight this unpredictable Minnesota climate. You can choose between waterproofing sealant, moisture-resistant paint, or wax polish.


Acrylic or silicone sealant will protect your fence against moisture as well as the sun's harmful UV rays:

  • If you want to remove the wood's natural shine, use a clear sealant. 

  • If you want to darken lighter wood, use a colored sealant.

Moisture-Resistant Paint

You can also find paint in a variety of colors that will also waterproof your fence. Although you lose the wood's natural shine, you have several options to choose from! 

Wax Polish

Waxing your fence will help repel dirt, dust, other particle debris, and moisture!

Wood Oil

If you're looking for a natural finish, wood oils not only create a beautiful aesthetic we can all offer some extra added protection. They accentuate the wood's grain, and depending on the wood type, there are different variations ranging from a thinner consistency to a stronger finish with UV protection.

Keep in mind that oils cannot be used over stains and sealants because this will affect the color, and they need reapplication every one to two years to keep their beautiful finish as part of ongoing maintenance.

Trim Low Hanging Branches

During the event of severe weather or in the winter, low-hanging branches become a threat of snapping off and damaging your fence. Trim low-hanging branches as you see fit to avoid them turning into dangerous falling debris!
