About Tomson Window
Serving Buffalo, Tonawanda, Amherst, Grand Island, Kenmore, West Seneca & Clarence, NY

Decorative pattern

Tomson Window has been proudly serving all of Western New York since 1978. We’ve stayed put in the same location in the heart of Niagara Falls throughout nearly 40 years in business. That’s how you know you can trust us!


Tomson Window is owned and founded by Michael J. Tompkins. He has worked diligently for nearly 40 years to build the business from the ground up. Since many construction businesses fail within the first five years, this is no small feat.


In the beginning, Michael was the business, handling estimates, ordering, and installations alike. As Tomson Window grew, however, he was able to take a step back from installations. Today, highly trained crews take care of window installations, allowing Michael to focus on what’s most important: providing estimates, ensuring customer satisfaction, and building loyalty. In fact, he still handles all in-home estimates himself.
