Serving the Soo Since 1994.

Since opening our doors in 1994 with a single plumbing truck, we've grown into DNM Mechanical Group—a team of more than 35 technicians and apprentices and a fleet of over 30 service vehicles serving homeowners and businesses across Sault Ste. Marie.

In 2022, we expanded into heating and cooling to meet the growing needs of our community. While our services have grown, our commitment hasn't changed. Today, our plumbing and HVAC divisions operate as one team, delivering the same dependable service our customers have trusted for more than 30 years.

Growing our reach. Powering innovation. Elevating our people.

Our mission is to grow a people-powered, innovation-driven MEP group with a bold mandate to expand across Canada.

Our staff brings decades of combined experience across plumbing and HVAC. We hire for two things: technical skill and a genuine commitment to client service.

That's because every technician who arrives at your door represents our entire company. Whether they're a seasoned journeyman or an apprentice learning the trade, they're local professionals who take pride in doing the job right and treating you and your home with respect.

Rooted in Sault Ste. Marie, we're more than a service provider—we're part of the community. We understand what makes Northern Ontario unique because it's where we live, work, and raise our families.

From local homes and businesses to the industries that drive our region, we know the challenges our customers face because they're our neighbours, too.

We have become a trusted name across the region on the strength of three things: expertise, integrity, and transparency.

Our customers vote us #1 in the Soo year after year — for plumbing, bathrooms, water services, heating and cooling, furnace repair, gas fitting, and fireplaces.

We are committed to innovation and to staying industry leaders as plumbing and HVAC keep evolving — new equipment, new efficiencies, new standards.

That means investing in our apprenticeship program and supporting the development of local trades. The next generation of Sault tradespeople is who keeps this city running.
