Watch for signs of moisture or water damage in your basement
When you have a damp basement, you’ll want to take special care in keeping an eye out for any signs of moisture or water damage. Look around the basement and ensure there are no spots where leaks might come in through cracks or other damage.
Fluctuating temperatures can lead to condensation on walls and ceilings, which may be hard to see but can lead to mold growth if left untreated.
Please do not use bleach, as it will kill off all of your good bacteria with how acidic it is. Instead, use the borax laundry booster available at any grocery store in their laundry aisle next to the detergents.
Mold in Your Basement – Ventilate and dehumidify your basement
Here we explain to you two ways to get rid of mold in your basement:
Ventilate your basement
If you have a finished basement, ventilation is essential to eliminate the moisture that causes mold. It would be best to have an exhaust fan and an intake vent in the ceiling. The exhaust fan will pull air out of the room while the intake vent draws fresh air into it. This way, there’s never stagnant air in your basement—any mold spores or bacteria will have time to settle down there!
Dehumidify as well as ventilate
Once you’ve got good ventilation, it’s time for dehumidification—which goes hand-in-hand with removing excess moisture from your home’s atmosphere. An excellent way to do this is with a dehumidifier set at different humidity levels (i.e., between 30% and 50%).
If you’re worried about dry skin or allergies during winter months (that seem to coincide with higher humidity), using one at lower settings may be helpful until spring comes around again so that you don’t overdo it on setting up something like this before its time arrives!
Replace rotten wood
If your basement has many molds, try replacing as much rotten wood as possible with pressure-treated lumber. If you can’t do that, consider replacing the entire floor with new materials.
If there is mold on the walls or drywall, check for leaks in your foundation and repair them.
Use mold-retardant building materials
- Use concrete blocks or brick to build your foundation and not wood.
- Use a vapor barrier to protect your basement from water damage, not wood.
- For example: if you’re building a new home, follow these tips closely to prevent mold growth in your basement!
Keep gutters clean and downspouts extended
The gutter system is key to preventing water from damaging your foundation. The gutters should be cleaned regularly, and downspouts should be extended so that any water drains from the roof do not drain onto your foundation or basement.
Gutter extensions are available at most hardware stores, and you can also purchase metal brackets or supports to keep them from sagging over time.
Watch the landscaping around your foundation
In addition to keeping your basement dry, you should keep your landscaping around the foundation in good shape. This includes keeping the grass cut short, clearing leaves and other debris from the ground, grading dirt away from the foundation walls, and keeping them free of excess debris.
If you notice water pooling on your property (for example, on a roof), consider installing gutters or downspouts that direct rainwater away from windows near the top of the foundation.
Mold in Your Basement – Seal the foundation walls
The first thing you need to do is seal your foundation walls. This will stop any water from getting into your basement and causing mold growth. Sealing involves applying a sealant rated for basement use all over the seams and cracks in the foundation wall, ensuring they’re fully sealed with no gaps or holes.
You can do this yourself, but it’s best to hire a professional because they’ll have experience applying sealants correctly and know what materials work best for sealing basements.
Maintain a relative humidity level of 45 percent or less
To prevent mold growth, you should:
- Maintain a relative humidity level of 45 percent or less.
- Use a hygrometer to measure the humidity levels in your basement. You can also use an electronic humidistat or an electric-resistance-type humidifier and thermometer (with built-in shutoff) set to shut off when the desired humidity is reached.
- Keep windows open to let in the fresh air and reduce moisture from the outside, especially during warm months when it’s more likely to accumulate inside your home.
- Keep the basement door closed as much as possible. When it’s opened, let air circulate before closing again, so it doesn’t get trapped underneath after being closed for some time.
Keep your basement dry.
Keeping your basement dry will help prevent mold from growing. You can do this by using a dehumidifier to reduce humidity levels and keep the area dry if there are leaks in the basement.
Maintain proper grading around your home
One of the leading causes of mold growth is standing water. Water seeping into your basement can lead to mold growth that can cause health issues as well as structural damage to your home. You can prevent this by having proper grading around your home and ensuring no puddles of water near your foundation. The ground should slope away from the foundation so excess water will run downhill rather than pooling near the house.
Follow these guidelines to prevent it
Mold is gross, expensive, and dangerous to have in your home. But it’s not hard to prevent it if you follow these points:
- Keep the humidity level in your basement below 50 percent. If it’s too high, mold can grow on walls and ceilings.
- Use a dehumidifier at least three times per week (more often if necessary). This will keep the air’s temperature down and moisture from building up inside your home.
- Ensure vents are covered when they’re not being used, so no outside air is being pulled into them by fans or other appliances like dryers or dishwashers that use electricity for heaters for drying clothes when wet clothes are running through them after washing cycles are completed with drying cycles. Still, since they already own them, there’s no need since they already exist elsewhere, so why bother investing more money into something already available elsewhere?
Mold in Your Basement – Final thoughts
That’s it! You now know everything you need to know to prevent mold from growing on your basement walls. It’s a simple process, but it requires dedication and diligence.
If you want your family to be safe from the dangers of mold and mildew, then this is the first step towards achieving that goal.
