I have an Anderson Engineered wood floor (LS3290) in my foyer over concrete slab which has been down now about six years. It's in great shape and I'd like to expand this floor by another 5' X 18' into my living room/hallway area. Where it currently stops and meets my carpet, the boards are cut at an angle. I'll have to remove some of these angled cut boards to continue the run. Is it possible to remove some of these glued down boards without damaging adjoing board? thanks.....

It's going to be very hard to do and not cause some incedental damage to the other planks. If the floor was left with a clean line you could put a header board in and continue off that easily.
