Review
Window project manager said we bought cheap windows and that lifetime will not do any warranty on the windows. We were charged for 2 dumpsters they only used 1 we were told no refund. There were more issues too many to list here.
Review in Westminster, CO
Windows need to be adjusted. The lifetime representative said it was good enough as it is. There is play when the Windows are locked. The downspout diverters are not installed correctly. The gutter guy argued about a gutter I had to show pictures of what was on the house before they removed the old one.

Salesperson was great. Window Installers were great. Siding installation was great. Two project managers were great. Follow up after the jobs were complete not great.

I have already recommended Lifetime Windows & Siding to a neighbor. She came over and looked at it and bought from Lifetime Windows & Siding herself.

They are the worst company I have dealt with in my whole life. They don't answer the phone. They keep pesking you from one person to the next person. On the day of my appointment, he didn't show up, call, or anything. I had to call him. No call, No show.

There were many issues with the installation.
Review in Lakewood, CO
The product is exceptional, but the installation process was lacking in attention to details and quality of workmanship. The project management was also less than what I was expecting to get in return for choosing LIfetime.

The communication and follow up by the team is great.
Carrie L.
Excellent customer service and installation. They left the house cleaner than when they got here.
Review in Wheat Ridge, CO
Poor communication and confusion prior to installation.
Review in Centennial, CO
Everything from the initial person who knocked on the door introducing us to the company, to the installer, to the supervisor, was a great experience.
Review in Thornton, CO
They weren't as thorough this time in the follow-up. I am a little disappointed in that. When they came out to measure my door, they were supposed to put a wooden board below the door, but that didn't happen. I will have to do it myself. I'm a little disappointed with the follow-through and that they didn't follow up like they did the first time when they installed my doors and windows.
