    I have that Klein non-destructive meter.. the second one he showed. Works well and very reasonably priced (

    Had a section of damaged flooring replaced. Replacement waited until the moisture content of the exposed subfloor matched the moisture content of several samples of the undamaged floor. It happened to be 11%, which I thought was high. But what mattered was that same measurements were found on several spots around the room.

    Tools like this will save home buyers from crooked builders, flippers and sellers. Home inspectors if suspicious of water damage, can get a reading without invasive or damaging techniques to warn buyers and lenders of hidden damage.

      We use Flir thermal imaging cameras. The one we used in the segment is the Flir e60. It has since been replaced. But it’s my favorite tool!

    Great video. I had a contractor come out to assess water issues around my home who tried to sell me a system that would cost me $12-15k using only the thermal cam. Nice to know they weren’t totally off the mark, but that they should have used some of the other tools to verify the readings.

    Can it read if there is water under a vinyl floor? Our shower overflowed a little, and I'm nervous is moisture is trapped under thr floor. Or will it dry since the heat is on now(low humidity) , and it was a one-time thing?

    • @dtemp132
      @dtemp132 Рік тому +2

      Generally, there needs to be an ongoing source of moisture for something to stay wet. I wouldn't be too worried about a one-time small-ish exposure staying wet for a long period of time.

    • @Direct_Home_Inspections
      @Direct_Home_Inspections Рік тому +1

      Yes it can. Always compare to a known dry area. Not all materials measure the same. Anything over 14% is considered wet but it's not an absolute

    For a little more than those proding moisture meters you can get a FLIR attachment for your smartphone that does the same thing as those infrared guns.

    I am painting my wood siding. I removed the paint completely on some of the planks. After the first primer coat I power washed all the siding. I have seen innumerable concepts online regarding how long you should wait before painting siding to avoid moisture in the wood ruining the paint. Is there any way to check for moisture in these situations, and what is the number in percentage of humidity to have as safe?

    I am here because my dishwasher leaked (brand new install) and the restoration company came out and used the pin meter on the floor joists and subfloor in my basement, it was reading 80% in some parts as I looked at his meter. I now have all kinds of fans and dehumidifiers going. How much water is too much water to dry out?

    Always say hard water damage never use that M word (mold), if you do the insurance company will say oh that’s old damage and not cover anything.

      It’s not always wet to the touch if it’s on the other side of the drywall. Not always visible either.

      Unfortunately your fingers wouldn’t feel the drywall being wet in this case, the moisture was from the back, and diffused through.

    • @Direct_Home_Inspections
      @Direct_Home_Inspections Рік тому +1

      Yes, it applies for foundation walls as well. Always compare to a known dry area. Anything over 14% is considered active. I'm making a video about them soon. Use these exact ones for home inspections.
