Darian replaced my screens in a timely manner and was very professional. Lifetime Windows and Siding has done everything they promised to do and I would recommend them to anyone looking for new windows. Thank you!

My windows were in desperate need of repair. My windows were foggy with condensation and white streaks inside the rotted-out double pane panels. The Marvin window looks fantastic! It's easy to operate, energy-efficient and beautiful with custom frame color options.I had a few questions about the quality of my installation on one window after the initial work was performed and the technicians came back twice more until I was pleased with the craftsmanship. Darian M. took the time to walk through the final steps of the project to make sure that everything was great. This is an example of the great customer service that they offer, and the contract was not closed until we agreed that the craftsmanship was top-notch.I would definitely recommend Lifetime Windows and the Marvin branded window specifically for a premium home upgrade. The improvement in the temperature control alone makes it worth it let alone the fact that I can see through the crystal clear E-glass much better than before.

Great all around experience. Sam and his crew replaced all the windows in my home in 1 day. They worked hard and had answers to all my questions. This company is not the cheapest, but they provide high quality products with exceptional service.

I had several windows and two patio doors replaced by Lifetime Windows and Siding. For the two patio doors, I also asked them to replace the frames inside the house too. The original crew didn't do a good job on the wood work. Anthony Esposito from Lifetime Windows came over. He not only adjusted my screen doors and patio door locks but also fixed two door frames. He worked very hard to make sure everything is right. I highly recommend Anthony to anyone who may have any issues. The company needs this type of guys with right working attitude.

Couldn't be happier with the Marvin windows we just had installed. The Lifetime Window team from Bill Kinsella in Sales all the way down to Roberto's install team made the whole process so easy. We wish we had done our windows 10 years ago had we known how easy it would be. Thank you to the Lifetime Windows team, we appreciate all that you did for us! Sincere thanks, Gerrit and Gretchen

I had my windows replaced by lifetime in 2012. Now it need some work done on them like caulking, resealing, new weather stripping,and a broken glass fixed. I thought there was lifetime warranty in my windows. At least on problems like broken seals.I've called they sent someone out, and haven't heard from them since, and this was back in June. Now late August. I have called every week and left messages. I finally got a call back from Reabecca and nothing since. Called a Manager , he was mad because someone gave me his number. Haven't heard back from him either yet.What has happened to customer service now days. I thought they could at least get back with me tell me when they can get to me if at all, so at least if they couldn't I can find someone who can. Larry, the Manager is now working with me and trying to get it going. Frustrated Candi

Paco and his crew arrived at 9am and left by about 4:30pm. They installed a patio door and 6 windows. They were very friendly and respectful of my home and time. They made sure I was happy with everything before they left. They even taught me a few things about installing windows. The project manager, Luis, stopped by once during the day to check on every thing.

I contacted Stephanie to have some minor repairs done following our siding project. Daniel and his assistant came out, did the repairs in a quick, efficient manner. I continue to be impressed and satisfied with Lifetime's guaranty. Stephanie is a gem and quickly responded to my needs.

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.

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++
