Basement damp proofing
Moisture in your basement can lead to mold and mildew growth, things that will create a musty, dank smell. The best way to get rid of the bad smell and also treat the smell is by increasing the air circulation in your basement.
Air bricks represent one of the most common solution for increasing air ventilation in basements.
But air circulation cannot do the job by itself. You will also need to prevent moisture from getting into your basement. Waterproofing the basement will definitely help the smell problem. You can use special sealing paint or you can install a water barrier.
Heating the basement
Besides the two solutions we’ve mentioned, keeping a constant temperature in your basement will also prevent moisture from appearing. This is because a steady temperature will prevent condensation. It will also help water evaporate and dry the basement.
