I am going to try to install new laminate flooring in my kitchen and need help at the door jams. When I'm cutting the piece that fits inside of the jam can I cut it close where it fits fits snug or do I cut the bottom of the jam off and slid the flooring underneath it? I don't won't a ugly space in between the floor and the inside door jam. If I have to cut it what type of saw would I need. Also, I have square type water heater in the kitchen. Will it be alright to have it sitting on top of the flooring or would this prevent the floor from floating and later cause it to buckle? I don't want to put 1/4 round around the water heater because it would look tacky. Any help would be greatly appreciated.
.....When I'm cutting the piece that fits inside of the jam can I cut it close where it fits fits snug or do I cut the bottom of the jam off and slid the flooring underneath it?...
Yes. An easy method to do this is by taking a section of the flooring (cut-off) and then placing it next to the door jamb...flat.
Next, lay a sharp handsaw, or Japanese Flush Cut Saw onto it. Side of blade on the floor piece. Cut slow and straight. The result is a nice clean cut, that yur flooring will snuggly slide into.
I believe that you can find Japanese Flush cut-type saws in the Big Home Improvement Stores.
