About Us
Built on family. Driven by expertise.
Keystone Window Company was born right here in Montgomery County — two brothers with a simple goal: bring honest work, quality products, and real craftsmanship back to the homes in our community.
Between us, we bring a unique mix of backgrounds you won’t find at your average window and door company. One of us is a registered nurse, which means attention to detail and doing things right the first time isn’t just a work habit — it’s a way of life. The other holds a degree from the Kelley School of Business, Indianapolis, so you can trust that every project is managed with professionalism and your investment in mind.
We’re not just a business — we’re your neighbors. Keystone Window Company is family owned, family run, and fully committed to protecting and improving the homes in our community.
