Installation
Getting windows is a big investment, and Lifetime wants to make sure that the process is seamless from start to finish. That is why we only employ the best installers in the business. Each member of our team is carefully vetted, certified and has years of experience backing their work. Our certified installation crew is our full-time staff, you do not need to worry about having subpar contractors showing up and doing a careless job. We take pride in our work and in our relationships with you, the homeowner. When we arrive at your home, we will begin with a walk-through to explain what we will be doing and to determine if there are any special care instructions or concerns about your property and belongings. We will make sure that the entire installation process runs smoothly and efficiently with as minimal disruption to your life as possible.
Lead Safety
During window installation, your home will be visited by one of our inspectors. Every inspector is trained and certified with the EPA. Their job is to inspect the quality of the installation by our window contractor, the safety of the job site and to ensure your property is treated with respect. This also ensures that Lifetime Windows and Doors always complies with the EPA's new regulations for the handling of Lead paint. Each Lifetime Windows and Doors installer has EPA training and is certified to handle lead paint installation on houses built before 1978.
Quality Inspection
When installation is complete, Lifetime Windows & Doors will take the customer on a final walk-through to assure they are completely satisfied. The job site is thoroughly cleaned and before we leave, and our crew will clean your windows.
Be Assured that We Stand by Our Work 100%
Lifetime Windows & Doors come with a no worry “Lifetime Plus” warranty. Everything about your new windows — the frame, the sash, the seals, the screens, even the glass — is guaranteed to meet your highest expectations. And the warranty is transferable to the next homeowner if you decide to sell!

What Our Customers Are Saying

I did extensive research for over three years and met with every significant window company in the Denver area before making my decision to go with Lifetime Windows and the Marvin Infinity windows. The Marvin windows are of high quality and the installation was done well with no issues and no need to come back to correct anything. I would highly recommend both the Marvin Infinity windows and the team from Lifetime Windows.

John Z.

I will not hesitate to call Lifetime for any future siding/window needs and would *highly* recommend them based on their commitment to customer service.

Amy M.

Lifetime Windows was fantastic. The quality of the product and installation far exceeded our expectations. The staff were incredibly friendly and took pride in the work they did. They also ensured that we were happy with the installation that everything looked the way it should. It is absolutely amazing the difference new windows make in heating/cooling our home as well as a decrease in traffic sounds. We are thrilled with our purchase and would absolutely recommend this company to any interested in replacing windows at their home.

Denni B.

I had the Marvin 'Infinity' windows installed. They cost a bit more and the turn around time was a bit longer but well worth it. For the first time my bedrooms were comfortable in the winter and my heating bill was about a third less then this time last year. Installation was quick and clean. I went with the fiberglass frame over the vinyl because it just seemed like a better window. I am an architect so I know a good window when I see it.

Jim F.

Over the past five years we have been replacing the approximately 35 windows in our 27 year old house. We've interviewed 4 contractors and employed two of them, including Lifetime Windows and Siding. We are very pleased with all aspects of our experience with Lifetime Windows and Siding. We went with Marvin Infinity windows as these have been very good for us in other locations in the house and the installers did an excellent job of installing the new windows with new trim.

Greg S.

Lifetime Windows replaced 11 of our vinyl windows and installed the Marvin Infinity windows (fiberglass). We LOVE them! Now that winter has come we can really feel the difference -- no more drafts and rooms are much more comfortable. The windows look great, and low E is a plus. Rory was awesome, returned calls/texts right away. Highly recommend Lifetime Windows!
