Hello all,
I have to say I'm **very** grateful for this board. :-)

I'm in the middle of renovating my entry and adjacent half bath. I had
posted another thread with questions and got really great answers -
**thanks!!** :-) :-)

I am now trying to determine what my subfloor is made of and if it
should be replaced.

Here's a pictu

A poster on another board took a look at my pictures and said that he
thought my subfloor was particle board and that wasn't going to be good
enough for my plans to install Hardibacker and ceramic tile.

Whilst the prospect of needing to replace the subfloor is daunting (I'm
thinking I'll get professionals), it also seems that if it needs to be
done, now is the time to do it.

My house is in central Ohio and was built in 1964

Can anyone help me out? What's my subfloor made of?

Thanks!
