Causes Of Mold
Mold spores are in the air everywhere, all the time, looking for a damp place to take root. And wood can provide one of the best environments for mold.
That’s because wood is a natural substance and porous enough that the mold spores have plenty of places to get in and start cultivating.
While a mold infestation happen can happen to anybody, there are a few things that will put you at higher risk of having moldy wood.
Here are some of the most common reasons:
- Living in a humid or wet environment
- Leaking pipes in the walls
- Leaks in the roof
- Condensation on the walls
- Poor ventilation in the home
- Poor drainage
As you can see, some of these things are really out of your control. You can’t control the weather, for example. However, others are things that you can prevent if you are proactive.
Here are a few tips for preventing some of these other causes of mold:
- Inspect your roof once per year. The best time to do this is right before your wet season starts.
- Have your pipes inspected once per year to identify any hidden leaks.
- When weather permits, open up the windows in your home for better ventilation. You can also place fans throughout your house to circulate the air.
- Get an air filter. We’ll talk about this more below.
- Inspect your home for signs of mold at least twice a year.
These are all important factors for keeping mold out of any wood in your house. But they are also helpful pieces of advice for keeping mold out of your floors, carpet, shower curtain, or anywhere mold may arise!
These are great habits to get into during any routine maintenance of your house, and by forming these habits you are really saving yourself a lot of potential work down the line.
You can put reminders in your calendar to make sure you are staying up to date with your inspections.
In addition to practicing these preventative techniques, you also want to be alert to how to recognize mold in your home. We’ll talk about how to do that in the next section.
What Does Mold On Wood Look Like?
Recognizing a mold problem on wood can be a little tricky sometimes. Because wood naturally has some color variation and a mold growth can happen so gradually that it looks like it’s just a natural feature of the wood.
This is why you have to be particularly alert, and learn to identify the signs properly so you don’t confuse it with something else.
Check for these signs of moldy wood:
- Patches of black dots spotting your wood.
- Streaks of green
- White discoloration
If you suspect something might be mold but still aren’t quite sure, take a picture of it. Then, each week, take another picture of the same spot and see if the suspected spot is growing darker or spreading outward.
If so, it’s mold. You can also get mold testing kits that can tell you where concentrations of mold are in your home.
Learning to identify mold is the second most important step, behind overall mold prevention. So learn how to recognize the signs, because the problem could be worse than you think.
3 Types Of Mold On Wood
There are a lot of different kinds of mold that exist but not all of them are equally common. Luckily, the 3 most common ones can be recognized by their color. In this section, we’ll take a quick look at black mold, white mold, and green mold.
There are big differences between the different types of molds, so it is important that you learn to tell the difference to know the severity of the problem.
Black Mold On Wood
Black mold can be the most dangerous of the molds. This is toxic mold and it is highly dangerousto humans.
Before you run panicking out of your home, you should know that there are many types of mold and more than one kind that appears black. However, you don’t really want any mold in your home.
And if your notice black mold, you want to treat it as quickly as possible. Even though it may not be the highly toxic one, it’s still a good idea to just get rid of it.
There’s no real need to spend time testing it to figure out which particular strain it is since you don’t want mold of any kind anyway.
So remember, if you see mold in your house that appears black, don’t panic right away. The best thing you can do is, as with any mold, get rid of it.
It is especially important to look out for black mold though, as it does have the potential to be quite dangerous.
White Mold On Wood
White mold, like black mold, can also refer to a few different strains, none of which are especially harmful to human health. Although, a moldy environment in the home can still lead to respiratory problems like constant congestion.
Additionally, white mold will cause rot and permanent damage to wood if you don’t get rid of it.
So, even if it’s not seriously toxic, you’ll still want to get rid of it before it causes irreversible damage to your furniture, deck, or walls.
Green Mold On Wood
Again, quite a few different strains of mold will appear green. And green varieties of mold are especially common on wood that is outdoors but can be found indoors as well.
Many of these green varieties can cause respiratory infections like pneumonia, bronchitis, sinus infections, and inflammation of the lungs.
So while green mold it’s not quite as toxic as black mold, it’s still harmful to your health and definitely something you will want to make sure you get rid of as soon as you notice it.
Whatever the mold you notice in your house, the best solution is to have it removed right away.
However, we recognize that this is could be an expensive or time consuming process, so it is helpful to know which types of mold are more cause for concern.

Here are 2 of the methods we have found to be most effective:
- Wiping furniture down with diluted dish detergent.

In both cases, open up the windows and leave the furniture near them for better ventilation so that the wood dries as quickly as possible.
Good ventilation is key to dry the wood and also to remove any fumes or odors.
How To Remove Mold From Wood Floor
Here’s a basic process for getting rid of mold on wood floors:
- Clear furniture away from the area to make sure you expose the entire mold spot.
- Apply a mold killing product of your choice. Use as instructed.
- Wipe away if required.
- Once dried, put furniture back in place.
- Check the spot regularly for a few weeks to make sure the spot is not reappearing.
How To Eliminate Mold On Wood Deck
Wood decks are especially prone to mold because they are outdoors and exposed to the elements.
Here’s what you can do do to remove mold from your wood deck:
- Follow a similar process as you did for the wood floor.
- Make sure that your mold killing agent is either safe for plants or that you are applying it carefully enough that it’s not splattering onto nearby plants or your lawn.
- Let dry.
- Apply a protective coat to your deck to prevent mold in the future.
How To Get Rid Of Mold On Composite Deck
Composite wood decks are a little trickier because it’s a lot more porous than a wood deck.
Here’s what you can do:
- Follow the same process as above. Make sure the deck is dry before applying the cleaner.
- Once the mold killing cleaner is applied, use a scrub brush to really scrub it into the composite wood so that it is getting into the pores.
- Use plain water to rinse off the deck after scrubbing.
You may need to repeat this process a couple of times before all of the mold is removed.
3 Natural Ways to Get Rid of Black Mold On Wood
If you’re not a fan of using chemicals to treat a mold problem, you do have some natural options.
Distilled white vinegar. This will work but it may leave its own vinegar scent afterward. And the acidity may not be good on delicate wood.
Hydrogen peroxide diluted into water.
Air filter/ventilator. This won’t kill mold but it will remove mold spores from the air in your home which will prevent mold from growing again in the future.
And also keep your lungs safe from inhaling mold spores!
Avoid using baking soda. While it’s very effective for other surfaces, wood might be damaged by it.
Tools Needed to Get Rid of Mold On Wood
The exact tools you need will depend on the method you choose but here are a few of the items you might need to have on hand:
- Air mask to prevent you from breathing in spores as you wipe them away and release them into the air.
