Hey All!

New here and to the DIY game. Just bought a duplex from 1914 and did the carpet lift up the corner test -- found hardwood! Spent the afternoon ripping it up only to find rot and mold

I'm going to replace the section(s) that need replacing then refinish the whole floor. Sadly I don't know how to determine floor species and need some help!

points of note that may help: Duplex from 1914, original HW, upper midwest lake region.

Thanks for any help I can get in advance!

Looks like Hard maple.

Do yourself a favor and replace that whole floor! Doing a section or sections then trying to sand and restain will likely cost the same as a full re and re with new pre-finished hardwood. With new material, you also get warranties and modern-looking selections, so its a better investment if your living in or flipping the house for resale.

Thank you! I thought it might be maple as our primary residences from the same era is also original refinished maple.

Thank you for your input.

Our goal is not to modernize the unit or flip-- part of rentability where we live is the charm and originality of original flooring, built-ins and stained glass leaded windows you get in 100 year old + buildings. In replacing the whole floor we might as well just put plywood down and carpet over :/

Old growth along with an average of longer boards is not what newer flooring is made. Sorry you found such a surprise under the carpet!
Once the floor is covered with carpet, it is abandoned. Restore it as best as you can.
Well placed area rugs are a great helper!
