Do not go with this company at any cost. They say you will receive a lifetime warranty but that would only be true if they stay in business. Check other review sites to see all of the other people having their own problems with Lifetime Solar. Once they get any of your money your are ignored and neglected.

I had lifetime install new Infinity by Marvin windows and they are beautiful! I needed a small adjustment with my patio doors and called for service. Joy was great in finding a time that worked with my schedule. The service tech, Darian, called me prior to the appointment to let me know he was on his way. Once there, he was able to make the adjustment very quickly. He was very professional and I would definitely recommend Lifetime Windows and Siding.

They went out and pick up the correct product the same day and installed it in about 2 days to complete. I have no idea why I had to wait so long if t... Read more

My husband and I just purchased a home built in 1950 and we knew that our first big investment (other then the house itself!) was going to be replacing the windows. Some of the windows were from the original build while other had been installed by previous owners in a - let's say - questionable manner (e.g. upside down, crooked, the works ... ). We scheduled quotes with several companies and Lifetime Windows came out on top in terms of quality and efficiency. There was no hard sale, and even th... Read more
