What Our Customers Say

Trusted by Local Builders

We let our work speak for itself — but our customers are happy to share their experience.

I've been buying lumber from Koszta for over ten years. The quality is always consistent, and the staff remembers my name. That kind of service is hard to find these days.

Robert M.

Marengo, IL

We used Koszta for the stone veneer on our fireplace project. They helped us pick the exact stone we wanted and cut it to size. The result was perfect.

Susan T.

Rockford, IL

As a contractor, I need a supplier I can rely on. Koszta delivers on time, their inventory is well-organized, and they never try to upsell me on something I don't need.
