Like other organic materials, wood can decompose over time. This can lead to deterioration, fungal infections, and rot. Because it can affect both the beauty and the structural integrity of a deck, they need to be maintained and eventually repaired. It will prevent both water and UV damage. Rotting decks can become soft, cracked, split, and discolored. They will need to be either repaired or replaced (depending on the severity of the damage).
Causes of Deck Rot
Wood decks rot when they’re repeatedly exposed to moisture, which will cause fungi (such as mold and mildew) to grow. Poor drainage, improper flashing, being next to a water source, or being close to the ground can cause water damage. Untreated decks with old or no protective stain or sealer are even more vulnerable, because they don’t have that extra layer of protection. But it’s not just rot you have to worry about. Excessive water exposure and rotting wood can also invite pests, which can turn into infestations that will damage your deck even more.
There is also “dry rot,” which is caused by a fungus that grows in damp areas where wood is present. It can spread quickly. It can also cause wood to crack and crumble, which can make it less durable. Dry rot often shows up as discolored patches, spores, and other forms of growth. This type of rot can affect any home or building, regardless of its age or location.
Having a good design that’s properly installed and having a good maintenance routine are the best ways to prevent wood rot. It’s a good idea to clean your deck at least once a year to keep dirt, mildew, and mold from accumulating. It’s also a good idea to inspect your deck on a regular basis, so you can identify and troubleshoot any issues before they get worse.
Signs of Rotted Deck Boards
Discolored wood that’s soft and spongy to the touch is the first sign of deck rot. Mold and mildew can also damage wood if they’re left untreated. Look for any signs of cracking, splitting, splintering, and checking wood. If you suspect that part of your wood deck is rotted, you can confirm it by prying a screwdriver into the wood that you believe may be rotted. The deck is most likely rotted if the wood is soft and can be easily penetrated.
You want to look for any signs of pest infestations and damage. You also want to look for any dark, discolored, or moldy areas. Be sure to look at the following areas for damage:
- Posts and wood near the ground.
- Around the ledger board.
- Gutters, sprinklers, and other neighboring water sources.
If you’re not sure about your deck’s condition, be sure to reach out to a professional for more information.
Treating Wood Rot
If your deck has rotted, there’s no way to repair the wood itself. You will have to replace anything rotted decking and wood. You can, however, prevent any additional deck rot by inspecting the damage, determining the cause, preventing water exposure, and keeping your deck maintained.
Here is what you need to do if you find wood rot on your deck:
- Determine the extent of the damage — Before you can figure out the cost of the decking and order materials, you need to know how much rot exists. Inspect every part of your deck (including the deck surface, substructure, and any other important connections).
- Replace any rotted wood boards — If you want your deck to be safe and attractive, you will need to replace any rotted pieces. If only a few have been affected, you only need to replace the individual boards. But if the rotting is more extensive, you may need to replace the entire deck.
- Take care of any sources of damage — Aside from the deck repair itself, you also need to take care of any damage that can cause wood rot. Look for any nearby water sources (such as a leaky gutter) or any spots where water is accumulating because of poor drainage. Fix any leaks, damage, or other issues that can cause your deck to rot more quickly.
