While it may seem as though a basement is the same as any other room in the house, the reality is that it needs some extra care to maintain a healthy atmosphere. Since moisture can accumulate rapidly under the house, keeping it fresh is vital. Does a basement need ventilation, too?
Your basement needs ventilation to prevent moisture from developing. Since it’s located under the ground floor of the house, you need to control the moisture levels to prevent harmful substances from growing, such as mold and mildew.
There are many different ways to keep your basement well-ventilated, and I’ll go through some of these in the rest of this article. I’ll discuss precisely why basements need to be ventilated, what types of ventilation are available, and what may happen if you don’t air the room out sufficiently.
Why a Basement Needs Ventilation?
Bacteria tend to thrive in moist, damp, or wet conditions — so keeping your basement well-ventilated is essential for a healthy underground environment.
Improving the air quality in your basement will help protect the airflow in your house and safeguard you and your family from harmful substances.
For the good of your wellbeing and that of your family, it’s essential to provide your basement with ventilation, as it’ll eventually protect the other rooms of the house as well.
It’s crucial to remember that the inhalation of mold or mildew can aggravate respiratory illnesses, such as asthma, in large quantities.
In fact, many respiratory disorders can be exacerbated by the presence of damp or mold. So, if you or your family are at risk, then it’s essential to keep close tabs on the humidity in the basement, especially if it’s a room you use pretty often.
Additionally, ventilation protects your home from a substance called Radon, a radioactive substance found in the ground and can be potentially harmful if inhaled in large quantities.
Aside from that, keeping moisture and dampness at bay in your basement will help you prevent foul odors from infiltrating your house. Furthermore, if you’re using your basement as a family room, bedroom, game room, home office, or laundry room, you’re protecting the health of the family members who use it.
Finally, if you plan on selling your house at some point in the future, maintaining good airflow in the basement is essential to the value of the house. Keeping it well-ventilated preserves the overall value compared to a house with a damp, moldy basement.
Ways To Ventilate Your Basement?
There are several ways to maintain a healthy airflow in your basement. Keeping that area ventilated is essential.
I’ll go through a few primary ways to ventilate a basement. Each can help you understand how to ventilate your basement correctly. You can use any of the options below together for the most effective solution.
Mechanical ventilation is a method that utilizes fans to circulate air throughout the basement. It can help you push any harmful air particles away from the basement and out of any windows you might have.
If you have at least one window, you can use an electric fan to push air out of the window and air out the room.
If you don’t have any windows, you can use an extractor fan installed in the walls of your basement. This ensures that a lot of the dampness and musty particles are making their way out of the room through a little fan installed in the wall.
This may not be the quietest solution to your basement problems, but it’s an inexpensive and straightforward way to solve the problem. It can be used in both winter and summer, and all you’ll need is a bit of electricity and a few hours to bring the humidity down.
Portable ventilation is very simple and requires a dehumidifier to do the ventilation work for you.
Dehumidifiers are medium to large-sized machines that extract air from its surroundings and push it through filters to regulate the humidity of a room. They work by sucking in moisture and keeping the air filtered to keep any bad smells at bay.
A decent dehumidifier usually costs $100-$200, depending on the brand and needs to have the filter changed regularly to prevent it from clogging up.
These machines tend to last for a long time, and although they can be a bit noisy, they’re still handy at combating the dampness that can build up underground.
For this type of ventilation, it’s not necessary to have windows installed in your basement. You can find a mid-range dehumidifier on Amazon.com for a reasonable price, such as this Waykar Dehumidifier. It can be used for spaces up to 2000 square feet (185 sq m) and can remove 34 pints (16.09 L) of moisture from the air every 24 hours.
Natural ventilation is by far the cheapest solution to promoting airflow in your basement. It would help if you already had windows/exterior doors installed in your basement, but otherwise, it’s straightforward.
To promote a healthy airflow in the space, open the windows on opposite sides of the basement for maximum efficiency. This creates a current of air that regulates the temperature and quality of the air in your basement.
As it’s exposed to fresh air, the less likely it is that moisture will increase in your basement. Any harmful substances that are present in the atmosphere inside the basement will be filtered out using this method.
Make sure to regularly keep your windows open to sustain a good airflow for best results. Once again, the only downside is that you need to have windows already installed in your basement. Still, otherwise, this is a budget-friendly and effective way to maintain a healthy atmosphere.
What Could Go Wrong if Your Basement Is Not Ventilated?
If your basement doesn’t have any source of airflow or superficial ventilation, then a few things could potentially go wrong.
If your basement isn’t ventilated, the air inside will become musty and will permeate other areas of your house. Once mold and mildew begin to grow, it could quickly start to saturate the basement ceiling, which will affect the atmosphere in any room that sits above it.
If you have wooden floors in your house, mold and mildew could contribute to warping the flooring. Wooden floors are easily affected by dampness, and this is very difficult to fix once the damage has already been done.
The condensation that would inevitably build up in an unventilated basement would also be subject to any moisture that builds up in the atmosphere; this means that the structural integrity of the basement would then be at risk of permanent damage.
By understanding your basement’s humidity level, you’re much better prepared to deal with any ventilation issues that may arise. The general rule of thumb is this: if your basement has over 50% humidity levels, you’re at risk of mold growth and exposure to dampness.
To make your life easier and to determine what kind of ventilation is best for you, you can purchase a SEISSO Indoor Thermometer Hygrometer on Amazon.com. It can help you regulate the level of humidity in your basement. It’s usually relatively inexpensive and easy to use.
Remember that your basement’s base temperature and the humidity level will change with the seasons. In the winter, you should aim to keep an ideal temperature of no more than 60°F (15.56°C), and in the summer, it should be 80°F (26.67°C) or lower.
Keeping your basement ventilated is very important, not just for aesthetic purposes and the value of your house. It’s also for your and your family’s health, enabling you to live comfortably without worrying about mold or mildew.
Dampness can be a big problem, especially in older houses, so maintaining the equilibrium of the air in your basement can help you take control.
