I just purchased a home built in 1828. The bedrooms have stinky old carpets. I lifted a carpet and there is plywood and a thin layer of foam on top of that. I want to have wood floors since my son has allergies. The floor has several coats of paint on it. Someone told me I should just flip all of the boards and then begin the refinishing process.

Any advice on this would be appreciated. Feel free to add any other tips or helpful suggestions.

Thanks
