I am a small builder, and I decided to used Anderson windows and doors for one of my projects; just wanted to try something different. It turned out to be a very bad decision. The qualities of the doors and windows were not as nice. The locks came with doors are cheap qualities and difficult to lock. Out of the 48 windows and doors that I purchased, three windows were warp within 6 months and one was jammed. I called the distributor to report about the problem, they told my that Anderson does not have any follow up service. So, I called Anderson myself, the service rep. told my that I have to provide the ID of the product, the CID on the glass and the measurement of the glass, and send them photos about the defects and they will determent what to do. I asked if they will send out someone to look at the problem and provide appropriate replacement. The service rep told me that they will not send anyone; they only look at the information I send them and determine at their end. The customer service is terrible. I will never use Anderson products for any of my future projects. I wonder if the management at Anderson ever read all these poor rating from all these customers.
