Water Damage Restoration Tools  

 

When called to water damage restoration, you must have a minimum of tools to do the job.

 

Extraction

 

Light wand - the basic tool for water extraction. (Compared to the old “weighted extractor” that had weights stacked on it) This is used to get started extracting the surface of the carpet. The light wand can be used to extract the top and back of the carpet, when floating it after pad removal. Be careful not to extract the secondary backing away from the primary! Carpet is 80 – 85% weaker when wet.

Weighted extractors – different than the “old” weighted extractors. For category 1 water damage restoration, they will extract through carpet and pad to do “in-place drying”. These are a must, when leaving carpet and pad in place and drying from the top.

Squeegee wand - a nice tool for extracting hard surfaces. The rubber edge on this tool is easily and inexpensively replaced.

 

Measuring to Start the Job

 

Thermal hygrometer - The 1st measuring tool needed on a water damage restoration job. This measures the conditions in the space above, under and around the wet materials. It can have as few measurements as temperature and relative humidity or include all 5 things on the psychometric chart.

Psychometric wheel – When you have a thermo hygrometer that doesn’t measure all things on the psychometric chart, dew point and grains can be determined with the wheel.

Psychometric calculator – When you have a thermo hygrometer that doesn’t measure all things on the psychometric chart, this calculator will figure the other 3 pieces of information.

Thermal imaging camera - Another helpful measuring tool. This is a tool that measures temperature differentials, between the wet and dry material, showing the user where there might be moisture. These areas are then checked, by a moisture meter, to verify that they are, actually, wet. Can be a real time saver on large jobs and will assist in finding hidden moisture, inside multiple layers.

 

Wet Surface Measuring Tools

 

Penetrating moisture meter – 2 pins pass electricity between them. The more moisture contacted, in the porous or semi-porous material, the faster the electricity goes back and forth.  

Scanner - sends electrical waves into the wet material and gets an indication of the moisture content based on the speed of these radio waves. This tool is great for relatively quick searches for moisture, but they are not as accurate as penetrating meters. They also do not give a percentage reading. It’s simply a number out of say, 1,000 or 300. Something to give you a baseline reading, for comparison, later.

Rubber backed non-penetrating meter - a nice tool that will give a percentage reading. 

Hammer probe – gets readings in multiple layers of wood floors and can find moisture in bottom plates, behind sheetrock. Best used from the underside of a wood floor as holes in the surface may be difficult for the customer to accept. When patched these holes will show up under certain light conditions.
