Moisture can go through your house in many ways including plumbing/roofing leaks, building material diffusion, flooding, air filtration, high levels in humidity and more. Due to the many ways moisture can be infiltrated into your property, it is recommended to hire a trained and experienced Moisture Inspectors.
Once moisture is in the air, it does not only affect health, it also affects the building's infrastructure. It can cause structural wood decay and increased humidity indoors (which causes condensation). Metal corrosion and undermined foundations also occur once the moisture affects the buildings. Another problem to note is that when foundation changes in volume and or soil that has been softened, the soil may loose its ability to support the structure.
