From the first time I contacted Renewal by Anderson through the moment the installers left I was pleased with the information, how I was treated and the whole process. The windows are gorgeous! We are really kicking ourselves that we didn't do this sooner.

This is our second experience with Renewal by Andersen and we have been pleased with the product quality and the professionalism of their employees. The installer also helped us solve an issue we had with a screen door we recently purchased. We would definitely recommend Renewal by Andersen.

Representatives and installers were all extremely professional and helpful. Love the windows and are so sad to have to put Venetian blinds in the bedroom since it is at the front of the house. Also, amazed at how cool the rooms stay in the heat with the new windows. Touched the window and there was no heat transfer from the very strong sun.

I could not be happier with the windows or the installation of the windows. The product exceeded my expectations and the windows look great. The installers did a great job and left my home perfectly clean.

I had it in mind and wanted to replace my windows but was unsure when or how to do it. But after my first visit from the Renewal Andersen consultant I was convinced this was a superior product that I wanted. After a second visit when we were able to work out a plan and value that met my needs, we committed to the project which was delivered by the date promised and windows installed in one day to my satisfaction. I was able to discuss important aspects with the installers and was very pleased. I'm enjoying the product and am looking forward to phase 2.

Renewal by Andersen Customer Renewal by Andersen Windows Hartford

Very happy with product and service. The installer completed a bump out with a significant amount of custom work required. It resulted in a very attractive update to my house. Customer support from main office was also outstanding. I wish this type of service were more commonplace from other businesses. Thanks

The installers Dave and Mike went above and beyond to help restore my home to it's pre-installation condition. Especially installing new brackets on the windows so my shades could work with the new windows. I would have been unable to do that task myself.

Renewal by Andersen Signature Fibrex® Material

Fibrex® material is a composite material that is stronger and more flexible than vinyl. This makes it ideal for homes in areas with extreme weather conditions.
Fibrex® material is stronger than vinyl, so it does not need to be as thick to provide the same level of strength. This allows for larger glass panes, which can improve the energy efficiency of your windows.
Fibrex® material is also resistant to cracking, pitting, corrosion, and rotting, so you can be confident that your windows will last for many years to come. Also, you do not need to paint your windows, which can save you time and money.
Our windows have undergone rigorous testing over two decades, proving their long-lasting durability.
