5 Star Testimonial by William Dirkes

We had 15 windows replaced (2 were lengthened) and a new large picture window installed. The process and service has been great. Josh and his team got it all done in two days. They were tidy and efficient. There were a few minor service issues but Michael was very responsive and took care of a few minor issues we didn't even see. The whole team was very good at communicating and took care of everything from start to finish.

Lifetime Windows & Siding

5 Star Testimonial by Marti Briggs

We got our ancient wood siding replaced in November 2023. It was a really good experience. From estimation through several weeks of installation, everything went very smoothly. Our project manager, Marty Lutz, was on site frequently and was a great communicator. Our install crew were terrific - true craftsmen. They truly did a great job with a complex project. We would recommend Lifetime to other homeowners in the Denver area.

This company did our sliding door. Front the beginning to the end of our project they were reliable and professional. Darrien and his crew installed our new door in a timely manner and did a great job. Overall I had no complaints and would highly recommended their product and service.

Lifetime Windows & Siding

5 Star Testimonial by Emily Diner

We hired Lifetime to do both our windows and our siding for our entire home and we could not be more thrilled with the final outcome. Vlad was our sales associate and he was very friendly and knowledgeable while walking us through all of our options for our windows and siding. Communication was great throughout the entire process as well. Any time we reached out to Vlad with a question or concern he was quick to respond. Communication with the company in general was great, we never felt out of the loop about anything. The installers for the windows did a great job and they were very careful around our plaster walls. Mike was the project manager for our windows and was helpful, especially when we noticed two windows were placed in the wrong spots. He made sure the problem was corrected first thing the next morning. The lady who was helping install the windows was also awesome and so nice. We had Hector as our project manager for our siding and had Kevin step in as the manager at the end of the job because Hector had another large project he was working on. We were worried about our plaster walls getting damaged during the installation of the siding and Hector made sure that the installers took their time while they were taking down the sheathing and putting up the siding to minimize any damage done inside the house. We were so happy with the work that the installers did. Victor and his brother were our installers and they were very meticulous and did such a wonderful job. Kevin stepped in at the end of the project and made sure that everything was done properly and even made sure to return to solve a problem we were having with our external power cables attaching to our house after the project was done. We would definitely recommend using Lifetime Windows & Siding

Lifetime Windows & Siding

5 Star Testimonial by Aaron Richardville

I had lifetime install new Infinity from Marvin windows and they are beautiful! I needed a small adjustment with my patio doors and called for service. Clark was great in finding a time that worked with my schedule. The service tech, Darian, called me prior to the appointment to let me know he was on his way. Once there, he was able to make the adjustment very quickly. He was very professional and I would definitely recommend Lifetime Windows and Siding. ** Update- Couldn't be happier. The amount of heat that comes through my west facing windows has noticeably decreased. Updating my mid 90's wood windows made such a difference.

5 Star Testimonial by Juan Vigil

Update to this review: Lifetime came out and fixed the issue with the spray foam. Jon Stone was super friendly and completed the cleaning. It looks amazing and we are super happy with the outcome. I am changing the rating from 3 stars to 5 stars since he profusely apologized about the mess left from the original installers. Original Review: The process of purchasing our windows went smoothly. On the day of install, it was a little bit of a different story. The job took a lot longer than expected and the windows from the inside look amazing. However, the outside is a mess and they didn’t clean up the spray foam on the bathroom window, which we can’t open since it’s a picture window. They also left a razor blade on our deck box, which we found right away before our 3 year old went outside. We’ve emailed and called about the mess and no one has returned the calls or emails. We are happy with the windows, but it seems the aftercare is definitely lacking, which is very disappointing. For our next project, we may need to look elsewhere since everything has been silent.

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

Lifetime Windows & Siding

5 Star Testimonial by Leila Sueper

We replaced 36 worn out vinyl windows and 3 exterior doors. Everything from start to finish was well executed and professional. Juan and his team were efficient, respectful, and clean. When they left for the day, it looked like no one had been working. These installers are, by far, some of the best I’ve worked with and I have done quite a few renovations. James, our project manager, came by daily to ensure all was running smoothly and to answer any questions. Our doors and windows are stunning and the project was seamless. To top it off, they even got things wrapped up ahead of schedule!
