Uncovering the Cause of Rotting Deck Boards

Owning a deck comes with the responsibility of taking care of an investment that’s meant to last. If not taken care of, you will have wasted your money and your perfect outdoor space will be dull and boring, or worse yet, need to be removed or replaced. Decks make your backyard more attractive and useful. But, the rotting of deck boards can ruin that over time if not addressed immediately.

Top 5 Reasons for Deck Board Rot

Depending on what kind and style of deck you have, the elements outside contribute a lot to its durability and lifespan.

1. Moisture

This is the main and most common cause of rotten deck boards. If there’s a leak in your roof’s gutters, overwatered plants, or close contact between your deck and the ground, deck rotting due to moisture is most likely to occur.

2. Brown Rot

You’ll easily notice brown rot through black wood that has been shattered into cubic shards across the grain. It can be really frightening when the boards come apart when touched. It’s the kind of rot that’s brought about by a fungus that creates enzymes to break down any wood’s carbohydrate structure.

3. Black Mildew

The black spots or patches in your wooden deck are a clear sign of black mildew caused by moisture. Most commonly, it appears in woods that were unstained or stained using a low quality stain that has no or little fungicide in it. You can try using weak bleach on the top surface to wash it off temporarily. For safer and more durability against rain for the long-term, undergoing a propriety deck repair and replacement is highly recommended, too.

4. Green Mold

Structural damage cannot occur with green molds alone, but it can be an indicator of a serious condition in your deck. Green molds are just algae or lichen that do not cause harm to wood but can mean that other deck rots may be able to grow in your wood in that area or in other parts in that condition.

5. White Rot

Oftentimes, white rot is found underneath a deck because it’s are vulnerable to the sun’s rays. The structural quality of the wood becomes damaged due to the enzyme that the fungus produces. Over time, the deck joists will become weak and spongy because of the white rot, necessitating replacement to ensure safety.

6. Age of the deck

Similarly, decks deteriorate over time which you should be able to foresee. The older your deck is, the weaker it becomes and the more flaws it has.

How to Prevent Rotting

· Replace the rotten boards right away.

Once detected, rot should be eliminated as soon as possible by replacing your deck boards. The fungus that causes these rots eats away the wood, which decreases your deck’s safety. You may observe rot after the snow or a heavy rain because most of them are due to the moisture stuck between the boards.

· Coat your deck properly.

Since moisture is the root of all the rot that occurs in wood decks, the most effective way to stop them is by coating your deck with a protective layer of a moisture-resistant seal. Deck stain is great at locking out moisture and preventing the growth of fungus while also improving its appearance despite being water-damaged or old.

· Choose waterproof materials for building a deck.

The type of material used for building a deck is always a big factor in its safety and vulnerability to rot. Traditionally, wood is the first choice for a deck. However, nowadays, there are other better options like composite decks and plastic decks that can serve you well for a long-lasting, waterproof, eco-friendly outdoor living space.
