Hi floorguy and Donna, Thank you so much for the response. How would I know the difference between gypcrete and real concrete? I was told it was concrete when I moved in. The guys who removed the popcorn complained that the downstairs ceiling is concrete, making it harder to remove the popcorn. Is the floater wood good for either type of concrete? If so, maybe I should stick with the floater type. Thanks a lot, jenny

HI "madaboutkitchens" I am sure your installer was talking about engineered floating wood floors that can be installed directly on your existing parquet. Theoretically,it should work on any sound hard surfaces. In reality, you would want to consider the height drop from your new wood floors to other floor coverings in our house. Is there any proper transition moldings available to connect? Will you be happy with the final look? The door jambs have to be cut and base boards have to be raised up. These should all be well planned or foreseen before any actions. Hope my 2 cents can help. Good luck with your project.

I was thinking fire hazard as well. That doesn't really sound like it is up to current code either. I think the floor part of the problem is fineâ¦you can lay another floor over it. But at this point with the wires etc. under there I would look at a floating click-installation wood floor. I would not be driving nails into a nest of electrical wires.

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.
