I had Lifetime install new Infinity by Marvin windows and they are beautiful! They called me prior to the appointment to let me know they were on the way. Our installers were very professional. I would definitely recommend Lifetime Windows and Siding.

Lifetime Windows did an outstanding job replacing our windows & sliding patio door. The crew are definitely skilled craftsmen who have experience in this industry. There was no damage, they made sure everything was sealed properly, were courteous, and did an excellent job cleaning up. The project went smoothly with great efficiency. We immediately were able to see & feel the heat reduction with the new Marvin windows. The whole experience was fantastic.

We had 16 windows and a patio door replaced by Lifetime and the whole process, from the first meeting and estimate all the way through the final installation, was great! The sales and office staff were great with communication and the installation crew did an excellent job. The installers were efficient, courteous, professional, and knowledgeable in their work. Overall, a much easier experience than I was expecting, and a great company to work with. Highly recommended!
