REVIEWS WHAT OUR CLIENTS SAY

The entire team at Lifetime literally left our house better than they found it. From the helpful customer care concierge, Marina Valdes, who was always there to answer any question, to the the window replacement team who were literally done in less than a day; he vinyl siding team who worked diligently and took less than week, and the gutter crew that refigured our gutters more efficiently. WELL done!! We can already tell a difference in the heating and electric bills, as well as consistent temps in the house and much less noise. We couldn't be more thrilled!

Lifetime Windows Colorado is an excellent Window company to use. From the moment we ordered our windows their team of professionals kept in contact with us, letting us know the status of our order. We didn’t have to call them, Marina and Rebecca kept us informed of when the windows would arrive and then worked around schedule for the installation. The installers Frank and Alan arrived on time, explained what they were going to do, and then they got right to work. They put protection on the floors and the furniture. They did not talk on their cell phones while installing our windows, completed the installation in a timely, though, and professional manner. We made the right decision purchasing our windows from Lifetime Windows. They explained to us how the window operate and answered all of our questions and concerns.

Darian did a great job repairing our windows. Friendly, communicative and very professional. Our windows are no longer carried by Lifetime and he had never seen them before, but he liked the challenge and figured them out. He has a positive disposition and a can-do attitude.

Matthew Reed was an excellent sales consultant. He was very knowledgeable, professional and friendly. The windows were available much sooner than I expected and I was extremely satisfied with the work that the installation team did and the beauty and quality of the windows.

Darian came to repair some strips on our picture windows. He was anticipating he’d arrive earlier than the scheduled them, so he called to ensure we were home and available for him to arrive earlier than planned. He was careful in moving our things in order to access the windows; and, explained how he worked around the nuances of our old home to make things work and look good. Thank you!

Lifetime Windows & Siding has been great to work with from the beginning! I first got introduced by Audrey Congleton on the Roofing & Solar part of the business. She made sure to connect me to right person on the windows side. The windows were installed in January with a great crew that Cannon Russell was leading. Our house is a geodesic dome, and with the extensive large sliding windows that were going at the front entrance, there is a bit of reframing with new header that needed to have permits pulled for. One window got cracked upon installation, as it was just a bit too snug. No questions asked, and they reordered the window, and were prepared to come back to do the work. Today, Darian and Sean Neu came out to replace the window. They were super friendly, efficient and did an amazing job. They are a definite customer focused organization, and they've been super communicative along the entire process.

Lifetime Windows and Siding has been a great company to work with and they stand by their work. We had one small air leak in a window they installed for us, but they came out to make a repair at no cost to us, true lifetime warranty. Darian M. Was our service tech and he went above and beyond. He was thorough and efficient. He was also very neat, besides the repair you would not know he was here.

Darian did an excellent job coming in and completing the job that had lingered on due to lack of communication with other people in the company. Wish we had him through the whole job.

Had an issue with our back french doors. The main door was not locking properly. Anthony Esposito diagnosed the problem quickly, acquired the parts and fixed it. He even adjusted the door without asking because he thought it was not sitting right. He was very professional and I would definitely recommend Lifetime Windows and Siding.
