Humidity in the basement is caused by many reasons. It really makes the space uncomfortable to be in as the dump basement smells a lot. Not only the smell but the fungus growing in the area causes health problems to the dwellers. It is best to instantly recognize the problem and set it right.
The reduction and prevention of humidity depends completely on what is the source of the moisture. It can be due to various reasons starting from rainwater, groundwater to it coming from inside the house or condensation caused by temperature differences.
First and foremost, find the culprit so that the issue can be closed from the main spot and you can prevent humidity. The sooner you identify it the lower will be your effort to reduce the humidity plus it will be cost effective and less time consuming.
You can get an exhaust fan for your basement. It works the same like the bathroom fan keeping the basement moist free by its high capacity vents pushing moist air away from the basement. One can also invest in dehumidifiers.
They work by condensing the moisture in the air into water with the help of cold evaporator coils. Many different shaped and sized dehumidifiers are available in the market.
The humidity levels get dramatically reduced by the use of a dehumidifier particularly in the dampest part of the basement. The reservoir needs to be checked and emptied regularly. If you ask your plumber they can attach the dehumidifier to the floor drain. Other than fixing fans or a dehumidifier, make sure you check the basement for any leaks or cracks and patch it up as it will solve your humidity problems.
