Lifetime Windows replaced all of the windows and 2 patio doors in our 16 year old house. After researching 4 different competitors, I found that Infinity by Marvin windows and doors are the Rolls Royce of windows in the industry today. Their glass, coatings, frames, and especially warranty are the best in the window business today. These windows and doors are such an upgrade to the builder windows and doors that we had. Just an incredible product. Also, we had Darian Manzanares out to the house to fix a couple of minor adjustment issues. Darian is a true craftsman with these windows and doors. He is very personable, knowledgeable, and fixed our issues quickly and efficiently. Lifetime and Infinity are proving to be the best decision for a fairly expensive decision that we have made in a long time. Great job Darian!!!

We had Lifetime replace all of the windows and both patio doors in our house. These windows and doors are the Rolls Royce of windows and doors. What an upgrade. After comparing 4 brands, Infinity by Marvin Are clearly the best available. After install, we had to call service out for some minor adjustments. We found out how good their service department is. I also find that their warranty is second to none. Anyway, Darian Manzanares came out to the house and had everything fixed and in tip-top shape in no time. He is a true window expert and has a passion for doing his work the right way. He knows these windows inside and out. He was a pleasure to talk to and have put to the house.

Just had Darian out to my home to fix the door Lifetime installed. Nothing wrong with install, just an old house that adjusted itself after the installation. Darian was personable, friendly and fixed the problem. He even handled the dog well.

Lifetime replaced all of the windows in our home and we’ve noticed such a difference! The Infinity windows are great quality and keep so much of the surrounding noise out. The crew was super efficient and very respectful while inside our home. Everyone communicated with us throughout the project and multiple project managers stopped by to check on the progress. The entire process was easy and seamless from beginning to end! We’re extremely happy with our brand new windows and would highly recommend Lifetime to anyone on the market for replacement windows!

Had some cracking issues around my windows (drywall issues). Darian and Robbie came out and repaired the drywall. They did a great job. Appreciate them coming out and fixing this! (I purchased windows from Lifetime 2 1/2 years ago.)

Lifetime replaced 5 Windows and converted a French Door to a sliding door for me in December. At the time of sale, the salesman was touting how fine the screens are, that they are Barry visible. Boy was he right! My son and dog have both run through the screen door tearing the screen loose. Thanks to Lifetime Windows’ lifetime warranty and the prompt and professional service of their service tech Darian, the screen was replaced both times within a matter of days!

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.
