We have nothing but good things to say

Whether it be the product or the service, Warren Windows has always exceeded my expectations. Their staff are friendly, knowledgeable and always wililng to help. When I began my window search in 2010, I dilligently researched the major window manufacturers - Pella, Andersen, Marvin, and a few other brands, and the quality of Marvin windows simply cannot be beat - the same can be said for Warren Windows. I would challenge anyone to find a better quality product offered by a better company. In addition, Marvin offered some great customized features, grill sizes, width and router profiles not otherwise offered by Marvin's competitors and when remodeling a historic home governed by the Board of Historic Preservation, detail is key.

At Warren Windows it is easy to find the right thing to make your home improvement project special. The Phantom Screens they helped us select made our project unique and incredibly functional. From design to installation, they made our project their number one priority.

We are enjoying our new Marvin windows as they provide more “glass space” than the old ones, even though we did not enlarge the openings in the walls.  Craig Connell has been an outstanding sales person for us.  He came out multiple times to insure he had the right measurements before ordering, and then came again to adjust the retractable screens after installation as they were not working properly.  We also want to inform you that Clint Van Zanten of Black Hills Construction Services did an excellent job of installing the windows; Clint was also the person who recommended Craig, Warren Window & Supply and Marvin Windows.

As a Contractor, there have been countless times I've been embarrassed when scheduled deliveries go NOTHING like they were planned, causing my customers to question my project management abilities.  My experience with Warren Window & Supply was the complete opposite. I received a call to arrange the delivery of my door, and during the delivery to confirm where I wanted it left. Simple actions, but sadly, all too rare these days. You should consider having your employees do training seminars for delivery personnel from all other local lumber yards and suppliers!

I've been building custom homes for years, and I've counted on Warren Window & Supply as a trusted partner on many of my projects.  Everyone at Warren Window & Supply is hardworking, honest and provides not only the best possible products for each job, but invaluable knowledge of the products they sell, like Marvin Windows and Doors.  Marvin has superior workmanship and quality behind their products, which makes them ideal for me. I wouldn't put a window or door that I couldn't guarantee to uphold high standards in any of the homes I build.  I highly recommend Warren Window & Supply as well as all of the products from Marvin Windows & Doors to all of our clients.
