I sell these windows as a broker, I do not work for WeatherShield, that being said. I am the service/warranty contact here. They are extremely well made. Never had an issue in the 5+ years we have been selling these. All products are received, installed, and warrantied better than other major brands we refuse to sell. Anyone would be absolutely impressed, happy and confident to have these windows and doors in their home for a lifetime! Plus the options are endless! Most Highly Reccomended!
