We are supposed to have a lifetime warranty through this company and it has been two years and one of my windows still will not shut. They have been telling me they ordered the part since then and takes three weeks to come in well after several attempts to get this fixed it is still the same way! I will now have to hire a different person to do it! Do not get your windows put in with them! The installers have no idea what they are doing either. Customer service is awful to.
