Jessie , the siding lead man was very helpful. We had some issues but he step up and handle the problem. The window crew and the siding crew were the best! Still waiting for a missed order window and screens to come in but Jessie was a great leader and is handling everything.

Shawn, Don, Eugene and Carlos did an excellent job of representing Lifetime's window quality, pricing and installation. I had six of their windows installed in my house. I highly recommend.

Anthony came out earlier today in an attempt to resolve an ongoing issue with one of our windows, and I cannot tell you how happy we are with his work ethic and professionalism. The issue has been an ongoing issue for a year plus, and he was relentless, not giving up until it was fixed. Thank you Anthony, you are a rockstar!!

Mike and Darian M. called to let me know they were on the way. They were courteous and professional, covering the floor with a mat in their work area then made sure the keys worked and I was happy with the operation of the sliding door. Excellent products and exceptional customer service. Thanks!

Lifetime replaced the windows in my home and my daughter's home in Centennial, CO. "Woody" was amazing; he came over during both installations and afterwards. Rebecca and Krista were on top of all my questions/concerns (I asked a lot of questions). I also appreciated their help to get the HOA's approval.The two installers (brothers) were top notch as well. They were careful and their cleanup was thorough; even helped re-hang the window coverings . I was updated throughout the two-day process and encouraged to ask questions.Update 7/8/21. Mike D. came by to repair the sticky caulk on the sliding glass door. He was GREAT…..thorough, knowledgeable, patient and kind. He also took some of the problem caulk to show his boss and told me to call if there were any more issues.

Got replacement windows & patio door from Lifetime Windows last year. We've been so pleased with the product and everyone from Lifetime that we've worked with. Recently needed a few adjustments. Darian M and Mike (Technicians) came today. Not only did they telephone to let us know they were available earlier for our appointment, but they were professional, polite, personable, knowledgeable and quick. Our issues were minor, but they were addressed with precision. It made having to deal with a service call (per se') actually quite pleasant. I highly recommend this company and Darian & Mike for service! Thanks!

Screen frame was damaged. Darian and Michael showed up on time, went straight to work, and made repairs on site. Thirty minutes the frame was repaired back in place. Both were friendly and professional. Far better than anticipated ordering a new screen waiting who knows how long.

A door I had installed a while back had a trim piece that had come lose. I contacted Lifetime and as expected, they immediately set up service to have the door repaired. The technician, Darian M. showed up and repaired the door without issue. The repair was not rushed and looked as good as new. A big thank you to Darian and all of the Lifetime crew. A++

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!!
