Alco Construction Co. has specialized in environmental and energy-efficient construction techniques for many years. In fact before it was the “in” thing to do, we became ENERGY STAR builders providing weatherization and green building services to home owners throughout the area, including pioneering a weatherization program for the City of Chicago.

Alco Construction Co. provides a home weatherization approach that air seals drafts and insulates building shells to better protect homes from leaking heat and absorbing moisture while reducing energy consumption. Many of our clients have saved up to 25% off of their utility bills and reduced their carbon footprints simply by weatherizing their homes. At Alco Construction Co. we will provide you with both air sealing and home insulation services at a rate you can afford and with a quality you can trust.
