Real, Local Reviews From Happy Customers


Fantastic work and workers. Love our new look. These guys were considerate, conscientious and on time. Clean up tremendous. They were even kind to my plants that surrounded their ladder during construction. I would highly recommend them to anyone. We would ask for the same team next time. Kudos to Grady and Trav who helped with our install

The Window Source of WNY helped me with a door repair for my home. I found the owner to be highly responsive, professional and knowledgeable. The repair he made was high quality and saved from a costly replacement. I truly appreciate this company’s expertise! I would highly recommend them, as they will remain my first call for any concerns in my home. Thank you!

Kawanza Mccall

I had an amazing experience with The Window Source of WNY! My grandparents were unsure of where to even begin in their search for replacement windows. They recruited me to assist. After shopping around, we still had not decided. A friend of mine referred us to SAK construction. We had an amazing sales consultant, his name was Kendell. From the moment Kendell started assisting our family, it was a breeze. He did a fantastic job from start to finish. We had very relatable conversation, he was easy to talk to and knowledgeable. The entire process and the financial portion was so thorough! My grandmother was so impressed and sold on them for her new windows by the end of our meeting with him. She isn’t great with computers so ask that I share our wonderful experience here! I obviously obliged.

I would recommend Kendell at The Window Source of WNY to anyone looking in need of windows or doors!
