Vinyl duradeck got installed over the plywood of our new deck (20' x 15') and it exposed a massive ridge along the main cross beam through the middle of the deck. My GC claims that the deck is level and that it is the seam of the plywood and that the vinyl installer should have seen this and stopped installing. There is a massive dispute now over who's fault it is meanwile me the customer is now further delayed. Worst part is that it is perpendicular to the seams of the vinyl so you cant fix one section.

Is there anyway to fix this and keep the vinyl on? To me it looks like 1/4 to 1/2 inch needs to shaved off because of the crowning. I fear it all needs to get wripped up and leveled and then re installed.

Any ideas are appreciated.

It's difficult to know who's fault it is based upon the information provided. However, it is totally irrelevant if the deck is level or not. It does sound like some water got under the decking material which caused some swelling of the wood... which then caused the 'Ridge'. If that is in fact the case.. it is then the installer's fault as the seam leaked. One would think that the installer placed the material over a flat surface ? If he did not.. then he should have advised the GC there was something wrong.
