POLYGON NORTHWEST CO

I contacted the State of Oregon Contractors Construction Board, as well as the firm Polygon NW employs to determine warranty claims. I was told by both, that this type of claim was only covered for one year from the date the homeowner actually moves into the home. This was impossible to do in my case, due to the fact Polygon NW did not notify me until almost 18 months after I moved in to my home that the exterior siding on my home was the subject of a class action settlement. After getting the notification from Polygon NW of the exterior siding settlement, When Polygon NW markets their new homes developments they highly tout the 3X10 year warranty. It did not in my case, match up to the claims that were made to me at the point of my home purchase.  I did some research on the exterior CertainTeed Weather Board fiber cement product, and determined that since as early as 2002 it was widely known in the construction industry, this siding had experienced as much higher than normal rate of failure. Why would a company with the size and stature of Polygon NW continue to use this type of product, and take 51/2 months to notify its customers they  had a product on their homes that was the subject of a class action settlement ? I must also add, that after the failed siding was applied to many homes in our development, that Polygon NW changed the type of exterior siding they were installing on the more newly constructed homes in our development, but, they did not notify the owners of homes that were included in the class action settlement for 51/2 months? I have contracted with a licensed siding company and they are currently removing all the exterior CertainTeed Weather Board fiber cement lap siding on my home, and, replace it with a James Hardie exterior fiber cement lap siding product. I would not purchase another home from Polygon NW.
