Don’t Take Our Word For It…

“[G5 Construction] played a significant role in the build out and construction of the new Hudson Area Chamber of Commerce office. Tim always goes above and beyond to ensure we are adequately taken care of. [G5 Construction] did an outstanding job of coordinating and executing every part of the construction process. We cannot thank [Tim and G5 Construction] enough for everything they have done to create our new space. We appreciate the time and effort Tim and his staff has put in to help us bring our vision to life!”

Mary Claire Olson Potter • PRESIDENT, Hudson Area Chamber of Commerce

“Sperides Reiners Architects, Inc. (SRa) hired Tim Gunderson to be the general contractor for the construction of our new office. The project started in May of 2020, right in the heat of the pandemic. Tim was outstanding in his attention to detail, and the team met our goals and needs to the fullest extent.

Our project was delivered on budget and on schedule. Tim has a unique skill of managing the details with sub-contractors and delivering the project to the owner with no “DRAMA.” We are delighted and happy with the end result.

We highly recommend G5 Construction to others!”

Nicholas Sperides • PRINCIPAL & CLIENT, SRa Architecture + Interiors

“Tim and G5 Construction have exemplified what a true subcontractor/general contractor relationship means to provide a client with the best possible value and quality that is expected. With Tim’s many years of experience and ability to work closely with everyone involved in the construction process, it makes for projects that are organized and efficient which is beneficial to all. G5 Construction is the type of company that every owner needs to hire to get missions accomplished on projects big and small. Tim has the knowledge, skill, and ethics that make him a leader in the construction industry.”
