What Your Neighbors Are Saying

Hear what your neighbors have to say about Keller Custom Windows.

We selected Keller Windows for our replacement windows in our recently remodeled home in Owasso. I initially didn't believe the windows were in need of replacement but quickly changed my mind after project completion and I had more time to inspect the old windows and inability to clean because of fog between the panes. We visited the Keller booth at the Tulsa Home and outdoor living show and also visited the nationally advertised company booth. We set up appointment for each company for the job estimate. The national company made a very impressive presentation and I believe they provide a really nice product with excellent reputation and warranty. The Keller presentation was a couple of days later. Their presentation was not quite as slick as the national brand but provided me with visual samples of their product (ProVia) and a copy oof their LIFETIME transferable warranty. The dealbreaker came when the price quote for the triple pane Keller Windows was almost exactly 50 percent of the national brand. Took about 6 weeks between order and installation. Our new windows are awesome! We are absolutely satisfied with Keller. Everything went as promised and the results not only enhance our views and also have had a very positive impact on modernizing the appearance of our home.

I recently had new windows installed by Keller Custom Windows, and I couldn't be happier with the results. Every time I drive up my street, I love seeing the beautiful view of my home with its updated and modernized exterior. The new windows have truly transformed the look of my house. Not only do they look fantastic, but I've also noticed a significant improvement in the temperature regulation inside my home. It stays much more consistent and comfortable now. Additionally, the sound buffering has made a noticeable impact, creating a quieter and more peaceful indoor environment. Overall, I am extremely satisfied with the quality and performance of my new windows from Keller Custom Windows. Highly recommend!
