I got a toe kick saw from Harbor Freight, then I cut one wall about 3/8 because it was flush up against it, does anyone think I also need to cut a groove between the three rooms to create a 3/8 expansion area under the door thresholds? What do I cover it with after I cut it? I saw some putty at HD or brass metal strips. Also, how do I get the buckeled areas to relax back down?
