I recently replaced 1200 square feet of floors in my home with Pergo Outlast laminate flooring. The floors are done and everything is installed, but I was not sure if I am supposed to screw down the thresholds. I have two exterior doors and on both of them I put the floors under the threshold. Before we had engineered hardwood and the thresholds were screwed into them. I'm just nervous to screw them down because I haven't been able to find anything saying its ok to screw through it. I would hate to see it crack/split when I screw it down. I would think I could drill holes into the floors before screwing into them and that would prevent any issues. Any thoughts on this?
The thresholds are both in place (not moving) with the doors opening and closing multiple times throughout the day for the last month.
