Mary Wallace

Lifetime and their employees are amazing. Not only is the product terrific. Solid windows that look beautiful and function perfectly, but the crew is exceptional. Dallin, the project manager, and Roberto and his crew were extremely professional, beyond competent, and so easy to work with. Their attention to detail, their problem-solving skills in replacing old windows, and the speed at which they installed, never sacrificing quality, were incredible. So impressed and pleased with everything we got. My house looks beautiful!! I would highly recommend this company and their products. Top-notch!

Jeff Lancaster

We are extremely pleased with the installation of our new windows. They look fantastic and have truly improved the comfort and appearance of our home. The entire process was smooth and professional, and the quality of the workmanship exceeded our expectations. Jairo and his crew are true craftsmen and Dallin stayed in contact through the entire process to ensure our satisfaction.

The windows in our house were the original from 1980, still in good shape, but definitely needed upgraded for numerous reasons. I am an extremely budget conscious person, and lifetime won my money! From start to finish was about 8 hours, but that included clean up and walk through. The big thing that won us over was the warranty, lifetime warranty no matter what happens (except acts of God of course). Looking forward to having a warmer house this winter! Of course I didn't take photos of any other windows in the house, but this is the before and after of our living room.

Such an amazing experience with lifetime windows from start to finish ! We had multiple quotes from several other companies and it almost felt like we were being scammed. Sat down with Krista at lifetime and she explained everything to us in detail and didn't charge us half the cost of these other companies. The installers were very clean and friendly, kept us up to date the entire process and really went above and beyond even replacing a few windows seals that weren't in our quotes ! Don't hesitate to use lifetime windows such an amazing company.

I just had my windows replaced by Lifetime Home Remodeling and the experience was beyond anything I expected! From beginning to the end I could feel that this company really cared, and when you are doing a project as big as replacing your windows, genuinely is all you could really want In the end. I am beyond pleased. If I could give 10 stars, I would!!!! Thank you Lifetime!!!

Jennifer Risdon

I recently had my second-story windows replaced by Lifetime and I couldn't be more impressed with the entire process. From the initial consultation to the final installation, the team was professional, punctual and meticulous in their work. Justin the project manager, was friendly, knowledgeable, and answered all of our questions. Alberto and his crew were highly skilled and took great care to ensure that everything was perfectly aligned and sealed. Great attention to detail and commitment to quality. Overall, I'm extremely satisfied with the results! I would highly recommend Lifetime to anyone in need of window installation.
