Floating floors are one of those changes in the industry that have been a blessing and a curse. One of the blessings with the floating floors is they are much more conducive to DIY installation. It doesn't require many special tools, it is fairly easy and doesn't require a lot of time. In this time of economic uncertainty floating floors have offered a less expensive way to redo your flooring without the additional cost of an installer.
The down side of the floating floor installation is there are serveral easily avoided issues that can make the project fail and ultimately cost more. One of those issue happened on a job I recently inspected. The flooring was developing side gaps, some of which were very wide (5/8"). I noticed a built in window seat on one end of the room. When I lifted the lid I discovered the builder had screwed the front panel through the flooring. The screws prevented the contraction of the floor during dry winter conditions and the resulting tension pulled the planks apart. Floating floors will not expand and close the gaps therefore the entire installation has to be removed and reinstalled.
