Please don't. The warranty will specifically state that the subfloor must be clean flat and smooth. The warranty/installation instructions will clearly state that if you are going over top of an 'old floor' it must be (clean, flat and smooth) well ADHERED to the subfloor. A floating floor is just that...floating. It is not adhered to anything.

It should take 30 minutes to remove the old vinyl floor. You will also want to pop off the trim on the walls (probably quarter round or shoe mold) before you install the new floor. Once the old floor is gone and the new floor is installed, you will then reinstall the trim.

And don't forget that the new vinyl will TELEGRAPH anything sitting underneath (like bevels from the old floor underneath) as well it will raise the floor height which means you will have to have a NEW transition strip created for the doorway.

If you simply rip out the old floor, you will likely be able to reuse the old transition strip currently sitting in the doorway.

Great advice given! I am surprised at the number of contractors that will do these types of installations.. voiding warranties left and right.

Thank you...we did decide to rip out the old vinyl floating floor. Will you give me your thoughts on putting plywood down to make the level even with our tile floor...which we are not ripping out.
