Hey! Glad to be a part of DIYChatroom. Look forward to hearing all of your expertise on my many, many questions I will be having in the next few months. My wife and I are a few months in on a 1930's house strip to the studs remodel. One question I have is how to lay the new hardwood floors we want to put in. (we are a ways from that, just finished demolition.) The home has original 3/4 in. wood run at a 45 to floor joists for the subfloor, then 2 1/2 in. wide pine flooring over the top. The floors are beyond refinishing and we want to start fresh. My original plan was to run solid oak over the top of the existing, install with staples. After some reading on forums like this I decided it best to glue and screw 3/8 plywood first, then builder's paper, then staple down the new. Is this a good option? The argument I have heard against it is the headache of cutting doorjambs and even door height, transitions, etc... but since everything will be new, (new prehungs, new tile in bathrooms, etc...) is this a better option. I am installing new throughout the whole house minus two bathrooms. 1600 sq. ft. Don't really want to pull up that much old flooring if this other option will still create a quality floor. However, that will add an additional 1 1/2 inches on exterior doors... any thoughts on what you would do would be appreciated. Thanks and happy to be a part of the forum!
