Squeaky Hallway... fix or linoleum?
Our house is about 65 years old. We're currently renovating the bathroom and some of the kitchen, including new floor. The hallway (between the bath and kitchen) has wide pine flooring. It needs to be refinished, and it's loud, so we have carpets on it. But the big problem: it squeaks terribly! We can see under the floor from the basement, it has 1x4 subfloor that the planks are nailed into.
I feel like the wood floor is valuable, and problematic to remove. Spouse and contractor want one single flooring from kitchen to bathroom. I want to use linoleum because it's more eco friendly and I love the soft feel (the little bit of red flooring you see in the 1st picture is the original sheet linoleum. It has held up amazing).
Is it possible to fix the squeaky floor and keep the wood? Is it even worth it? Or is it way better to do the whole floor all at once and continue from kitchen to hall to bathroom?
Thanks!
