I have already undercut the door jambs so that the laminate can slide beneath. My question is how to capture it to slide under if I requirement to hold the laminate at a 45 degree angle to catch it to snap into place. Right now, the single way I can see how to do it is to start the row at the door. Suggestions?
Answers:    You've already undercut the jamb, which is appropriate. To snap the pieces together, you don't have to start at the doorway. With oodles of the floors that I've installed, I was competent to take a crumb, cut off the lip that doesn't mate with the piece within the doorway, snap it to the piece that I was trying to install, and slap it LIGHTLY with a tack hammer until it clicked into place. Then I removed my block and continued on with the floor. Good luck.
Well, you can do one of two things. You can remove the molding or they cause a saw that cuts door jams and moldings. You can rent one at your local hardware store. These saw are used for tile, laminate, and wood flooring installations.
