How to Prevent Rotting with Decking

A typical reason for deck replacement and repair is wood decay. Homeowners may have to pay up to $2,000 or more to replace or reorganize their decks if they don’t know how to stop it from spreading. Wood rot is a minor problem that may be repaired for very little money if it is discovered early enough. Homeowners risk their deck’s structural integrity collapsing and causing injuries if they ignore the signs of decay.

Comprehending Wood Rot

Wood rot, or the loss of the cellulose components that give wood its stiffness, is brought on by microbes in the wood. Over time, the wood’s integrity is weakened, and its structure is broken down by the bacteria that break down the cellulose. 

Not all deterioration or damage to wood is caused by bacteria or the rot they cause. Cracking, splintering, and other physical damage caused by various external and natural factors might cause some harm.

That being said, dry rot and wet rot are the two forms of rot that harm decks the most. Either decay may impact greater portions of the deck than are visible. Since the surface of their deck seems to be intact, many homeowners may think it’s OK, but bacteria are actively breaking down cellulose and ruining the structural elements of the deck.

Dry Rot

Dry rot thrives without much water. It may go unnoticed for years, keeping the wood surface intact. Surface dry rot will occur. Similar to cotton, it will be fibrous and soft. After becoming apparent, the fungus has damaged the wood. On the surface, it seeks healthier wood to eat.

Wet Rot

Wet rot, like dry rot, is a fungal infection that needs moisture. Basement fungi cause damp rot. Decks are particularly prone to decay when temperatures are between 4°C and 38°C. Wet rot causes dark or light, spongy spots on a deck. You may smell mustiness.

Learning Ways to Prevent the Spread of Rot

The fungus that causes wet or dry rot must be killed to halt its spread. You may chat to a local carpenter about rot prevention, but moisture management and fungicide are the main methods.

  • Determine Cause

Most cases of wet rot are visible, while dry rot is difficult to diagnose. A leak or drainage problem commonly affects the deck. If you cannot discover the problem, see a specialist. Determining the source helps limit rot and its spread.

  • Apply Boric Acid

Since fungal infections cause wood rot, fungicides are required to manage or eradicate the problem. The best wood treatment is borate or boric acid. The best thing about this product is that it may lower the danger of wood rot during construction.

Fixing Rot

You can restore the damage from wood rot, but the procedure is somewhat different for wet and dry rot. Since damp rot does not spread as quickly as dry rot, you may usually repair the afflicted portions and reconstruct them if needed using wood putty. Repairing dry rot is more complicated since it propagates swiftly, especially within beams and boards. Usually, you’ll have to take out and replace any damaged parts.

Rot may be a distressing issue. The professionals at can assist you if you see soft, spongy areas on your deck and you suspect wood rot may be the cause. You’ll save a ton of money and worry if you have the issue evaluated and fixed before it gets worse.
