:: Company Credentials

A Proven History
Alsco was established in 1946, by Sam Sugar. Anthony Gravina, GM 1953-70, assumed ownership in 1970. Currently, Alsco is owned by Jean Gravina. Beginning a long-standing tradition of a family-owned business where the values of integrity, customer service and hard work define the company.

Originally, Alsco started with storm windows and doors, but soon added top quality replacement windows and doors, siding, patios and sunrooms.

Adhering to the principles it was founded upon, Alsco has rapidly grown to become one of the most well-respected home improvement companies in Colorado with thousands of satisfied customers.

A Proven Alternative to Windows

Alsco-Cardinal searched extensively for a manufacturing partner who could work with us to develop the trademarked Cardinal High Altitude Window® Series that will truly meet the needs of Colorado homeowners. After visiting and interviewing major manufacturers we selected Amerimax, a $750 million a year company.

Together, Amerimax and Alsco-Cardinal developed the High Altitude Window® Series and the Insulated Super Glass® Package, built in Colorado FOR Colorado!
