About Us

Northwoods, Inc. is a family owned company that believes its clientele is an extension of Northwoods. In Chicagoland alone, Northwoods has successfully completed more than 30 Chicago Public School mechanical renovations and another 1,200 mechanical renovations in the public housing market.

As we continue to grow, Northwoods has expanded beyond the Chicago market. We recently completed a complete design-build renovation of the steam system for the U.S. Army Corps of Engineers at the Soo Locks in Sault Ste. Marie, Michigan.

The Soo Locks is just one example of how Northwoods is a proud partner in rebuilding America. Our exceptional performance in both the field and office brings quality and value to every project undertaken, no matter the size or scope of the work involved. Northwoods’ clients can expect a quality product, and a job finished on time, on budget, and in a safe workplace.

Installation and renovation of:

  • Steam and hot water heating systems
  • Chilled water cooling systems
  • Gas piping
  • Rooftop units

Design/Build of mechanical systems:

  • Complete design engineering solutions

Did you know that union workers have 80 percent fewer accidents on the job? Northwoods sets the bar for safety on its projects, winning a Safe Workplace Award from the Mechanical Contractors Association of Chicago in 2010.

“Northwoods embraces the concepts of partnering between Owner, Engineer, General Contractor, and Subcontractor. Their input throughout the design phase of this project was critical to the timely and cost effective results that were achieved. Their experience and knowledge of complex mechanical systems was beneficial throughout the design and construction of the project. We look forward to working with Northwoods Inc. on future projects.”
