Last week we laid a pre finished oak floor from Travis Perkins and to be honest I'm quite impressed with how it looks when it's down.
This is the floating floor type, laid on a foam underlay with the tongue and groves all glued together. Lots of beams and doorways to go round and oak skirting and beads made out of the same stuff, at the customers request but unfortunately the longest length was only 4ft so lots of joints!
The customer seems really happy with it. My only concern would be how long this "high" finish will last compared to my usual oiled finish, but when you're having to pay for labour this pre finish makes it a lot cheaper rather than having to pay me for a couple of days to sand, stain and oil the floor. Also it means that the furniture didn't have to leave the room whilst we were laying it, we did one half then moved everything over and did the other.
