Hi Linda,

You cannot install hardwood over particle board, it will need to be 3/4″ plywood to ensure the floor stays stable. Please let us know if you have any other questions!

Throughout the house is plywood subfloor with particle over the top of that. My husband is insistent that we take up the particle board and replace it with plywood of the same dimension. There are no pet stains or other imperfections in the particle board and I don’t think it’s necessary to replace it. What are your thoughts?

Hi Kelley,

Thank you for getting in touch! Unfortunately I won’t be able to provide much help with your question. It is very important you treat and clean the concrete with the proper materials so it doesn’t come back or harm anyone. I highly suggest getting in touch with a certified mold expert to ensure it is removed completely. Please let us know if there is anything else we can help out with!

It clearly was the cause of water getting in from the root system of a large tropical plant growing up underneath the stucco of the exterior of the house. We cleared that away but moisture is still getting in. We would really like to install hard wood floors rather than recarpet. My question is, how do we treat the moisture that has gotten in the concrete foundation under the window?

Hi Ronnie,

Thank you for getting in touch! I apologize but I am having a hard time understanding your question. I would suggest getting a contractor out to take a look at the area in person to ensure you are installing the flooring correctly. They would be able to give you much better advise as they can see everything in person. Please let us know if there is anything else we can help out with!

We do have luon over a 3/4 ” plywood floor. I have a few questions.

1. Can I use a heavy mill plastic to act as a vapor barrier?
2 my husband thinks that just using a 15#felt is all we will need.
3. Does hardwood need to be on padding. I saw a vapor barrier/padding how will that work?
I want the added vapor barrier in plastic and the felt. Will those work together or should we go another way.
4. I like the gunstocks/oak/utility/ 3 1/4. Can we mix it up with another more rustic board even a shade darker and/or lighter. I like that look.

Thank you for your time.
Regards,
Erin

I don’t see that talked about here, am I missing it? Tongue and groove subfloor post different problems than a plywood subfloor! How do we combat those problems. Plywood subfloor is straightforward. Screw every 6 inches.

I bought 1/4 inch thick cork as the underlayment in rolls.
The floor will be installed over a plywood subfloor on the upper level of the home.
What should be my first step in this installation? What is your feeling about the 1/4 inch cork underlayment?
