Relative Humidity And Secondary Damage

Water removal is the most important part of the drying process on almost all water damage jobs.  You have to make sure that every drop of H2O on the floors, walls, and furniture are removed as swiftly as possible to prevent it from evaporating into the air!  When you are attempting to dry a property you need to know about relative humidity and secondary damage and the potential damage that they will cause!  Relative humidity is telling you how much water is in the vapor form in a particular area. When you have a relative humidity level above 60% then you will start having secondary damage. It is very similar to what happens when take a long hot shower and forget to turn on the bathroom fan. The walls will be slick with moisture and the exact same thing happens when you have damage in your home or business  You could and will get mold growth on places that never even got wet if you allow water in vapor form to dwell to long unnecessarily.

high humidity caused this secondary damage

This flooded crawl space had high humidity which caused secondary damage on the rafters. Mold grew on the wood!

    Mold remediation is expensive so it is important to know humidity levels in your home.  It is not just your building you have to worry about when you have high humidity but all of your content as well.  If your furniture or belongings are sitting in a room that is all fogged up then they are going to have a film that will permit mold to grow.  Your fabrics such as sheets and clothing will also be an excellent place for mold to develop.

If you understand about vapor pressure then you will know that if you have a low humidity outside and high humidity inside then it would generally be a good idea to open the windows and “burp” out the wet air.  We would not automatically recommend to open the windows on all flood jobs because the reverse is also true.  If the humidity is higher outside and you open the windows more moisture will rush into your water damage problem.  We recommend that every time there is a water problem that you would want to have a controlled environment where it is possible to dictate the relative humidity, air movement and possibly temperature in a particular area. We would call that a drying chamber. If we can set up a controlled environment on the water job we can prevent not only high humidity but also secondary damage as well.

The best way to create  drying chamber in a flooded basement is to simply close the door. Separate the air system from the rest of the home and remove all the water. Set in the right drying equipment for the right amount of time and make sure not to leave any wet insulation left behind.
