I have the floor as level as it's going to be but it seems there may be a 'high' joist issue that makes the landing tread area off by quite a bit from one side of the landing area to the other. Anyway, there's nothing I can do about that. I have even had a coupe of pros look at it and say the same thing.
I have another question if someone can help. Once the new flooring is down and I am ready to install the new landing tread I am not sure how to attach it to the new riser and sub floor (the original oak floor in this case). The new landing tread is a lip over type that is designed to cover the edge of the new flooring. It will sit on the edge of the original oak flooring and new riser for support and is fully exposed. Is there any way I can mechanically fasten the landing tread besides adhesive? I would like to use a couple of nails or screws to help keep it secure.
