While this may be a discussion of semantics, believe it or not, there have been court cases over the use of “percent moisture content” (%MC). It is a common misconception that meters always measure in %MC. In fact, they rarely if ever measure %MC accurately. Therefore, it may be better to use the term “points” when referring to readings taken on a loss site. Points provide relative readings; lower numbers imply that there is less potential moisture than in higher readings. When “point” readings in the affected area are close to those in the unaffected area, it’s a good indication that the structure is dry.

Ever wonder what goes on at the job site when you’re not there? A data logging device can tell you. Data loggers record data (including humidity, temperature, moisture levels and air pressures) at pre-determined time intervals. This allows you to evaluate the conditions present between each visit, or during the entire course of the project. Some reasons to use a data logger include:

• Occupants may cause conditions to change by manipulating drying equipment and/or building envelope.
• Risk of secondary damage is extremely great due to high levels of moisture, extensive loss area or sensitive and valuable materials.
• Restoration requires the use of very low humidity and/or abnormal temperatures that may result in secondary damage by over drying and/or rapidly drying materials.

Restoration effectiveness is often dependant on one critical skill: good communication. This cannot be over emphasized. And good communication should extend to all interested parties of a water loss. Poor communication can produce undesirable consequences such as: disorganization, work being done out of correct sequence, even potential health concerns. Here’s how you can avoid a couple of common communication mistakes:

• Instead of saying “Don’t touch the equipment,” explain to the customer the necessity and benefits of keeping the equipment running continuously.
• Don’t over promise by saying “Every job we do is dry in 3 days,” because you set them up for an expectation you may or my not be able to deliver. Instead explain your process of drying and monitoring, and that the job will be done when the structure is dry—for their safety.
