    We were very satisfied with our entire experience with Renewal by Anderson. Noise through the sliding door was reduced remarkably. Heat coming through the doors has been reduced as well. We have ordered six new windows from them and are looking forward to having them installed.

    I'm looking forward to the next phase of the window replacement project, which I hope to begin next spring (2016).

    I had no idea the wood frame was laminate wood. Which made it harder to stain. I was disappointed that I was not told it wasn't real wood. Therefor I had to spend more money to get the wood stain!
