DRG Mechanical Inc

We’re locally owned and deeply rooted in Northwest Iowa, and we’ve built our reputation on reliable service, expert craftsmanship, and honest communication. From our home in Lester, we serve homeowners and light commercial clients in Sioux Falls and the surrounding communities of Lester, Rock Valley, Inwood, Sheldon, Sibley, Canton, Brandon, Tea, Harrisburg, and Luverne, Minnesota. Our plumbers and HVAC technicians are certified, licensed, and fully insured, and we approach every project with the same care we would bring to our own homes.

Our work covers heating and cooling, plumbing, geothermal, and water treatment. We complete full mechanical installations for new homes, remodels, and light commercial projects, including HVAC, plumbing, and geothermal systems. For new construction, we install residential and commercial plumbing designed to last, coordinating with general contractors to help keep each project on track and up to code. We also work directly with homeowners and contractors on kitchen and bathroom renovations, plumbing upgrades, reroutes, and the replacement of aging pipes.

When plumbing problems arise, we focus on accurate diagnostics and lasting repairs for hidden leaks, slab leaks, and deteriorating pipes. We repair and replace standard water heaters using trusted brands such as Rheem, and we install energy-efficient, space-saving tankless units for endless hot water. Whether we’re completing a full mechanical installation or addressing a specific plumbing need, we bring precision and professionalism to every step. We also believe clear communication matters: we explain the available options and provide upfront estimates so our customers know what to expect before work begins.
