Alenco’s storied history began way back in 1986 out of Olathe, KS. Our mindset from the beginning was to deliver the finest in Kansas City home improvement and beyond with our quality services. Since our inception, we have rapidly grown up to our present location in Lenexa, KS. Our 36,000 square foot building has more than enough room to contain our warehouse, production department, the entire administrative staff and one of the biggest showroom floors in the greater Kansas City area. We began by simply offering vinyl siding installation. Through those successes, we moved on towards creating a more comprehensive package for the exterior of our customer’s homes. After adding Thermal Industries vinyl windows to the mix, we were off and running. By 1994, we were building high-quality Sunrooms along with so much more. We’ve continually aimed to deliver the highest quality products which not only increase the allure of our customer’s home, but the overall value as well.
