We're in the process of replacing all the windows on the main floor. Steve Tuttle, the Installation Manager, stopped by this morning to measure all the windows and verify the window choices we made, earlier. Steve arrived exactly on time and well prepared to do a thorough job of measuring for installation. Steve is professional in both attitude and action. This seems to be a trait exemplified by all the employees of Renewal by Andersen of Alaska. Our experience to this point in the process has been fantastic. I highly recommend considering Renewal by Anderson of Alaska if you're considering window replacement.Update 9/3/2021: Our windows are installed and they are absolutely fantastic!! The windows are Andersen, so, obviously, they're high quality and beautiful, but our installation team, Bobby and Aaron, went above and beyond. They are the epitome of Professionalism and Customer Service. Again, if your considering window replacement, we highly recommend Renewal by Andersen Alaska.

Daniel Perez has shown his dedication and expertise on what he does. He showed accuracy in measuring the windows that will be installed. For the short period of time that I spent watching him and chatting with him gave me an impression that he is knowledgeable and a very valuable asset to the company. He was respectful too and was able to answer all my questions. He is an employee for keeps.

Salesman Nick was quite knowledgeable about the product and company history, personable and helpful. He answered all questions to my satisfaction and gave good advice regarding window maintenance. Follow up scheduler Derek was very helpful as well and made custom changes to the installation plan to get a better result. He also answered all my questions.

I can't say enough good things about the people who work for Anderson. Derrick measured for my doors and is absolutely wonderful to work with-professional, detailed oriented, and wanting to get things right and this is a challenge in older log homes which I have. When he came, he checked on the windows which he had also measured for just to make sure that they were working well. It is his dedication to quality and customer service that makes folks keep coming back. You are very lucky to have him working for you!

I requested Renewal by Anderson of Alaska to install a picture window for a circa 1940's log house. Quote process was professional and thorough and Mel Ramos did an excellent job with the proposal and setting up the subsequent filed measurements for window fabrication.Brian Harris did the field measurements and proceeded to do an exacting evaluation and explanation of the process. The age of the log house made the project interesting. Brian's experience with remodels in Alaska allowed him to address certain issues more common to "older" home. Brian also did a professional and efficient job.

Very professional and personable. Answered all of my questions and up-front about possible issues with paint ridges on outside due to difference in window trim. This is the second time we have used Renewal. Very happy so far
