Great Lakes Plumbing Heating & Fire Protection Company

Great Lakes Plumbing Heating & Fire Protection Company operates as a mechanical contractor in Westmont, Illinois, delivering integrated building systems across plumbing, mechanical, and fire protection disciplines. The business holds a 4.5-star rating derived from two client reviews and maintains standard weekday hours from 7 AM through late afternoon. Founded in 1946, this family enterprise has accumulated nearly eight decades of continuous operation serving the Chicago metropolitan region and surrounding collar communities including Naperville, Downers Grove, and Oak Brook. The company maintains a physical presence at 430 Plaza Drive in Westmont, fielding service calls through their primary line at (773) 489-0400.

What distinguishes Great Lakes from standard trades contractors is their in-house engineering capability combined with design/build project delivery. Their website explicitly notes having professional engineers on staff, which enables them to tackle complex system challenges rather than simply installing pre-engineered solutions. The firm operates across diverse commercial markets ranging from data centers and healthcare facilities to educational institutions and life sciences laboratories, sectors that demand precision piping and code-compliant fire protection installation. Their service division handles both systems they originally installed and legacy systems from other contractors, positioning them as a technical resource for ongoing maintenance rather than merely a new-installation specialist.

One client review specifically references the company's multi-generational heritage, noting the family has operated the business for over sixty years. The single documented customer scenario describes the contractor as a trusted plumbing provider within the community, though the review offers limited detail about specific service scenarios or technician interactions. With only two total reviews available, prospective clients have minimal documented evidence regarding response times, diagnostic approaches, or the granularity of their emergency service capabilities.
