I have spent 10 months trying to resolve an issue with my delaminating engineered wood floor. The floor was less than 4 years old when the problems started. A flooring inspector came out and ran temperature and moisture tests on the environment and flooring, and everything tested normal and within limits. The inspector was hired by the manufacturer and his conclusion was that there must have been a moisture event for the boards to delaminate. There has never been a moisture issue and I have followed all of the ProSource cleaning requirements using Bona. I am very disappointed in the customer service provided by ProSource. While they sell Pinnacle flooring products, they will not back up what they sell if you have a problem. It takes weeks for them to return calls, and no real solution to fixing my $14,000 floor unless it comes out of my wallet. I have had a good experience with the customer service in the Pittsburgh location, however, not so much with Coppell. It is looking like I will need the courts to resolve this issue.
