BE SURE you take a minute to read the Installation Instructions AND the Warranty to be sure your floor conforms to coverage (in addition to what Steve suggested you do.) This way, if you have any more questions, you can ask them all when you ctc. the Pergo People.
As an aside, if moisture is a 'problem' now, I'd be sure to fix them regardless of whether Pergo warrants the floor or not. In due time, you may be asking 'us' if $1000 is too much $$$ for a pro to get rid of termites!!! My best to ya and hope this helps.
PS: You can get the Warranty and Installation Instructions at any of the Home Centers or from any Retailer that sells Pergo. Have them make a copy of them if they won't let you walk out of the store w/them.
