My contractor mistakenly placed new red oak (kitchen, stairs, hallway, and one bedroom) next to my existing white oak flooring (dining, living and two bedrooms). He kept telling me the difference might not be very noticeable after staining. Moreover, old and new hardwood will look different even they are white oak anyway.

I am thinking to remove the newly installed red oak floor, but the new kitchen and two other build-in cabinets are installed on top of the red oak floor already - not to mention the baseboard.

One flooring contractor said he can push new white oak in the cabinet/baseboard without any damage, while another two said I need 1/4 round to cover the gap (which I do not like).

Do you think it is worth to remove the the red oak flooring? Is that possible to replace the red oak without damaging the existing cabinets and baseboard? Or I should try to stain the floor instead? Please help!
