Robbie was incredible! Perfect customer service, fixed the reported problem right away. He also showed me how to easily remove a window for cleaning instead of struggling with screen removal. I'll ask for Robbie if we ever have issues again. He is a greatrepresentative for Lifetime Windows!!

Brandon did an excellent job finishing the project! He was detailed and thorough. He had the difficult job of matching faux painting and it was immaculate! He made sure everything was perfect! Thank you Brandon! From Julie 😂

Lifetime windows installed high quality windows with a lifetime guarantee. The guarantee carries over to the next owner when I sell too. After installation one of the window balances broke. Within a short time Their service tech came and fixed the window, and did some additional maintenance on the others (installed handles on the upper windows for easier opening). Excellent service, amazing value, top notch materials. Highly recommended. BTW the service tech, Darian Manzanares, was extremely good, efficient and friendly. Thank you.

Darian Manzanares performed window and screen repair today at our rental and he did an excellent job. He was on time and was very personable and professional. He explained why the screens were difficult to remove. He cleaned out the dirt/debris in all the window frames and showed me his trick to remove the screens more easily without using the tabs. I am always pleased with the responsive and quality service from Lifetime Windows. I highly recommend this company.Julieann Tibbetts

Brandon and his crew, Callum, Gary and Josh, did a wonderful job staining new windows. They were prompt @ 8, clean and paid attention to detail. And they reinstalled my 4 panel stained glass windows 12' up. Thank you!

We had ten windows installed to replace 80-year old windows that had wood trim. Lifetime was able to make the style we wanted. Every step of the process was smooth and timely. I was particularly worried about the color of the wood and windows but Brandon W, the finishing manager, consulted and chose the perfect stain to complement our baseboards and old oak floors.Every team member did an excellent job. They were friendly, polite - and loved our dog!

Lifetime Windows and Siding replaced the windows in our 1926 Park Hill home. They were professional and responsive. They matched the stain of the new windows to our walnut trim. When we had a miscommunication about the stain on the kitchen windows, and the company made it right and stood by their work. Our project manager was Luis Valles and the head of our staining team was Brandon Whitney. They were both professional.

We had our siding, windows and front door replaced about a year ago. Any issues we have had they have come back to fix, no questions asked. Anthony Espisito has been a pleasure to work with on our door issues. Very professional and friendly!

Greg and his team, along with project manager John were really professional and communicative as they approached a difficult window install. The windows were really big, and up high, and they figured out how to do it. The windows look great and we are very glad that we went with Lifetime.

Our house is over 25 years old with the original windows and exterior doors. The seals in the windows were ruptured and the doors leaked. We started working with Lifetime Windows and Siding in 2019 to develop a 2 year plan to replace all of the windows and exterior doors. In December 2020 we completed the plan, and we could not be happier. The quality of the windows and doors exceed our expectations, and they look good. The staff, from the sales team to the installation people, were professional and answered all our questions which made us comfortable with our decision to use Lifetime.

Replacement for install. There ended up being a problem with one of the blinds in the sliding glass door. A tech came out within a week and fixed the issue. I love this company. They definitely back the warranty for a lifetime. When I need my windows replaced I will go to them. Not the company I used before.
