THERE YA GO!
Finally someone has touched on what I think is a real negative issue with this type of flooring.
ALL of the floating floors that I am aware of require you to undercut your door casings and in some cases undercut the jambs also to complete a proper installation. The elevation of the cuts to accommodate a floating floor is higher than most other types of flooring. And in some cases you must add some shoe-mold or quarter-round to your existing baseboards if you should choose not to remove them. So what happens when you want to return to a more traditional floor covering and you have already ruined your wood trim? Now what?
Well, there is no good answer. It will be too late then.
This is one of the reasons I quit installing floating floors several years ago. In essence I was going out almost daily ruining peoples homes and quite frankly it bothered me. People in general like floating floors because they are inexpensive to buy and because they are what they are (snap together floors) they are also inexpensive to install. Hey, the best of both worlds, right?
In my thinking people are being suckered into buying the latest concept in flooring because its initial cost can be relatively low and installation is quick and painless and they are not being told about the far-reaching damage a floating floor really can cause to their home.
My suggestion is to "THINK TWICE" before buying any laminate or floating floor.
