Do you have a wet or damp basement?

You don’t have to suffer the consequences of living in an unhealthy environment. Even if you don’t spend much time in your basement, the humidity will eventually affect the air quality of your entire home. The same thing happens if your Crawlspace is not properly waterproofed, dampness will get into your hose and will affect the energy efficiency of your appliances and could lead to sever health issues.
