Drying Water Damaged Buildings in the Hot Humid Summer

Drying a water damaged building in the humid weather is much different than drying a building in the dry weather. In many areas of the world there is a dry season and a wet season.

In the dry season it is often so dry that the use of dehumidification in a water damage is only necessary to remove excess moisture created by evaporation of moisture from wet building materials and contents of the home. The facility is typically dry in one to three days with minimal use of dehumidification.

When the season changes and we get hot, humid weather everything changes. In humid weather dehumidification is used not only to remove moisture created by evaporation but its used to create an atmosphere conducive to allow evaporation to come to pass. When the air is humid water does not readily evaporate.

How can you tell whether or not the air is conducive to allow evaporation? You can only do this by measuring the relative humidity and temperature of the affected air space and then make the necessary calculations to find the absolute humidity or humidity ratio of the air space. This absolute humidity is measured by the number of grains of water there is in every pound of air in the airspace.

If the air is not dry enough, it is highly unlikely that structural materials like concrete, wood and stone will dry. In any water damage situation the water damage technician should be closely monitoring the moisture content of all structural materials in the facility. Many disaster restoration companies use infrared cameras to help track areas that are affected by moisture.

It is extremely important to deal with disaster restoration companies that are concerned with drying your facility until their meters show that your structure is dry. If the company you are dealing with is not providing you with this information then you are exposing yourself to possibly horrific consequences. Sinister mould grows easily in water damaged buildings. Mould can grow very quickly in improperly remediated buildings.

General contractors and carpet cleaners are often the first people called in to remediate a water damage situation. These type of contractors may or may not be able to properly dry a building. Do your homework and ask your contractors questions to determine whether or not they have the training to be able to dry a building.

Ask them if they have the moisture meters (not sensors) to be able to track the process of drying. Ask them whether or not you get a copy of the records at the end of the job. Ask them whether or not there are hard to dry structural items in your structure. Ask them how they are going to dry them. Ask them what their drying goals are. Ask them whether or not they have water damage remediation training. Ask them when they received their certification. The water damage business has progressed significantly over the past five to ten years. There are dramatic changes in the Standards for water damage and someone without recent upgrades in their education may no longer understand the new findings of the drying industry.
