Get an intrusive moisture meter. We first started and were at 44% everywhere now our highest is 15%. FWIW, I did read below 10% is great.


This. Harbor Freight sells them. Oh, new lumber moisture is anywhere from 7-12% moisture content.

Did you treat for mold?

Depends on how old your house is, how long water sat in it, and how quickly you got to it. Older houses have porous studs but shouldn't matter as much if water rushed in and rushed out. If you were able to get into it quickly and gut it quickly, then no more than a couple of weeks.

It took me almost three weeks when my basement flooded (different storm). Humidity is not our friend when trying to dry out.

Sounds like the target in dryer areas of the country is for 16%, so I'm thinking 20% would be a good goal. My dehumidifier is saying 35% right now and it was at 43% when I started on Saturday. I have a WiFi gauge that is reading just under 30% on the other side of the house.




The relative humidity of air is not the same thing as the moisture content of a stud. Relative humidity of indoor air is optimal in the 45-55% range for normal living conditions. Lowering the air humidity level will help pull moisture from the wood, but do not confuse the two. You need to test the moisture content of the wood using the tools linked in this thread.

Yes. Still treating. I started stripping hardware off of the "save these solid wood doors" & mold was in the hinges.

If you are thorough you can do it in less than a week. IF you have AC running to the lowest setting and add a de-humidifier.
AND you keep all doors closed as much as possible and seal all drains. I spray 91% alcohol then after drying a mixture of Borax.

I have in the past gotten the moisture readings in a flooded house under 10% in 5 days.
