I want to say something about the installers of these windows. They great group of guys. Help us understand the process of the installation. TJ told me they will incase all the trims around the windows and window sills with metal and make them air and water tight. He kept my wife and myself informed on how the job was going. Now that windows are done have noticed a change in temperature of the house for the better. I will know how much energy bill we will savings in the month to come since temperatures will be dropping next week. By the way Patio door and windows looks great. TJ you did a great job.
