I'm sorry, but you just don't sound like a flooring contractor to me.
I would be asking you those questions if I was interested in having a floor installed.

Hardwood moisture and humidity
What is the recommended humidity level in a home with hardwood floor? What moisture reading is normal for a sample taken from a probe in the wood for moisture? Wood is 3/4" solid Hickory unfinished. Thanks!

B.D.R. - I should be more clear in my question. We have humidity in the mid 40's, and moisture at about 6% in a hickory floor. These seem like great conditions. Floor acclimated for about 3 weeks in air conditioning this summer. We have noticed that boards have either shrunk on the groove side, or were slightly mis-milled. Has anyone experienced anything like this? Thanks!
If your using a meter with the metal prongs then your only measuring the moisture on the surface of the material. You need to use a meter like the Wagner mmc220. That's the only accurate way to figure out what the materials moister content really is. I don't see humidity levels like that in these areas as we are in the mud 35's here normally in a conditioned space. If your material has shrunk it sounds like it was not low enough moisture when it was installed.stewartflooring said:B.D.R. - I should be more clear in my question.

wood comfort level is the same as a humans..What is the recommended humidity level in a home with hardwood floor? What moisture reading is normal for a sample taken from a probe in the wood for moisture? Wood is 3/4" solid Hickory unfinished. Thanks!
35=45% ideal and what any mill or manufacturer wants.
6% would be ok determined by your location..
considering the hardness of Hickory..this sounds good.
the shrinkage...considering it Hickory makes sense.
Hickory runs wild..how wide are the boards?
do a google search..you will find tons of issues regarding Hickory floors..the next will be Maple..and then Brazilian cherry.
these materials constantly experience issues with rapid moisture changes

Refer to section IV Appendix D to see what the average expected moisture content should be for your part of the country.

Here on the north coast,I try not to install hardwood in the winter.It is EXTREMELY dry.In the summer when the humidity goes up to 95% and they dont run air-conditioning,the H.O. will be calling calling because the floor will be cupping cupping.What do you mean you acclimated the flooring last summer????,are you crazy?rolleyes:
