Who We Are
Our team at ProList 123 has been in the business since 2007. We are a family- and women-owned company. We are a quality control professional provider of attic insulation in Chicagoland, Illinois, and our goal is to deliver quality service and satisfaction to our clients.

In this day and age, many companies offer professional insulation services. In most cases, the client won’t know what should be done around the office or house and how much it costs. Typically, they only want to make sure that their office space or home is well-maintained and everything is fully functional.

With that, we at ProList 123 assess the office space or home to determine what needs to be done to ensure everything is in optimal shape. Our professionals have vast knowledge in different industries and work to guarantee the satisfaction of our customers. We have a quality-controlled process that makes certain any type of work done will be within industry guidelines and with the best products for the project. We strive to provide fair prices, as well as honest and straightforward estimates.
