Restore original wood flooring - Hard Flooring job in Palmers Green, North London

Job description

I would like the original wood flooring in my living room and downstairs hallway to be sanded down and restored. Some floorboards need changing/nailing down and there is a small area of concrete where the chimney breast used to be that needs replacing with floorboards. I would like the gaps between floorboards filled. Floors are in generally good condition in our 1930s house. Would appreciate a quote please. Thank you.
