Ply Gem Windows & Doors

In June 2013 we took possession of our new home built by Parkhaven Designs. The windows were installed by Ply Gem and in January 2015, they still haven't addressed a major deficiency despite committing to do so upon realization of their oversight. The weather sealant was not installed on two patio doors which allows for air to enter the house so in the winter, it's a major issue. We have also had issues with 3 of the windows not closing properly (crank system). Their product may be to standard, but their service is not in our experience.
