I recently did an open concept in my kitchen losing 2 baseboards (water) one on kitchen wall and another were the patio door is now. I have this middle wall. Would it be difficult to install a baseboard on this middle wall and connect to the baseboards that on each each end of the openings. Will the floor and basement ceiling need to be cut to perform this work I am having my floors done next week.

i hope this makes sense. thank you
