What causes mildew and algae on wooden fence?

Most of the time, mildew problems are extremely similar to mold problems. You may think of this as the midway ground between mold and green algae. Compared to mold, it doesn’t harm wooden fences as much. It’s not quite as risk-free as green algae, though. A wooden fence that has mildew on it should not be ignored. Although it can damage the fence, getting rid of it isn’t all that difficult. You should be able to handle mildew problems well if you know the problem. However it takes little time and effort to get rid of them but it is not impossible.

How can I get rid of mildew on my wooden fence?

Fence staining

The procedure of staining your wooden fence is quick and simple. A wooden fence stain is available from your neighborhood home improvement retailer. It takes a day or two. Ask the employees at the home improvement store what they suggest for your particular fence since you might need primer first.

Fence painting

Painting and staining is the same procedure therefore you can apply one method at a time. You can add a coat of paint after your stain has been applied, dried, and set. If you want a fence in a single color or something other than wood grain, this is an excellent alternative.

Use power wash

Sometimes there are some stubborn stains, mold, green algae, or mildew and it gets really hard to get rid of them. Power washing is the only method you can get rid of.  You should power wash your wooden fence as soon as you discover any green stains on them. It’s also fine to just power wash the fence a few times a year as a preventative measure. But keep in mind that by using power wash regularly you can harm your fence therefore use it twice a year.

Use bleach solution 

You can use bleach for removing stubborn mold or algae growths. People often warn about bleach but by using the right method you can use bleach carefully. Never directly apply bleach on wooden fences. First mix it with the water then clean your fence. Clean the fence with a hard brush to get rid of any dirt, and then thoroughly wet it.

Scrub with the brush 

In some cases, mechanical removal is far more efficient than chemical removal. Use this technique, especially if you see moss or textured algae growing on your fence. The bristles on a scrub brush are stiffer and tougher than the bristles on a standard household brush, therefore David says that’s what you should use in this situation. Using a brush rather than a scrub pad makes it much simpler to get rid of green algae.

Use a mix of water and vinegar to wet the scrub brush before using it to clean the green algae. After clearing the fence of all green algae, gently spray it with water from the hose.


A wooden fence will get weaker if mold or mildew is allowed to grow there. You can use a pressure washer to attempt to remove the mold off the wooden fence. Also, you can hand scrape the fence with a brush to clean it. It makes sense to combine bleach and water in a bucket.
