The Last Gutter Company You’ll Ever Need
For 50 years, Citadel has set the standard in seamless gutter systems.
We Set the Standard. Everyone Else Follows.
Citadel Seamless Guttering Systems isn’t just another gutter company — we are the standard-bearer. For over 50 years, our family has protected homes, businesses, and industrial facilities across Central Illinois with one relentless mission: build gutter systems so strong, so precise, and so dependable they outlast the storms and the decades.
It all started in 1975, when our family purchased the first gutter machine. From that moment forward, we weren’t following the industry — we were shaping it. Each generation sharpened the craft, refining the methods, and carrying forward a reputation built on uncompromising quality and trust. Today, Citadel is more than a business. It’s a fortress of expertise.
We are certified Alu-Rex installers — the first in the state of Illinois — delivering world-class gutter protection systems like T-Rex
and DoublePro with warranties that last a lifetime. Residential, commercial, or industrial, we engineer every system to exacting SMACNA standards (the national standard for sheet metal and air conditioning contractors), ensuring flawless performance and maximum protection for every property we touch.

We don’t operate like a small outfit — we project strength. Multiple crews, advanced systems, and a culture of excellence designed to dominate.
