But when the last few floorboards of your laminate floor need to be laid under the door jambs or through the door lining or door frame it seems impossible to get them in without.
Finish carpet in doorway.
Smooth out the carpet over the doorway and feel it with your hands to locate the area where it meets the other type of flooring.
Place a straightedge on top of the carpet and cut along the line using a utility knife to trim off the excess.
Just push the edge of the carpet down into the gap all the way across the door and trim any strings off.
Use your utility knife to cut the carpet to the size of the room adding an extra 4 to 6 inches on each side.
Also tuck the carpet into the ends where the carpet meets the jambs.
After the carpet is stretched onto the tack strip and cut to the correct size it needs to be tucked down into the gap.
If you nail one down always nail it to the subfloor and not to the pergo flooring.
I use a hook bill to do this.
During the flooring installation laying laminate in a doorway perfectly is not so difficult when you start laying the floor boards at the wall that has the door in it.
