GSM, Inc. Introduce
For residents and businesses across Southern Minnesota, particularly in the New Ulm, Mankato, and surrounding areas, finding a single, reliable contractor for critical services like plumbing, heating, cooling, and roofing can simplify maintenance and emergency situations dramatically. This is where GSM, Inc. (Gag Sheet Metal, Inc.) stands out as a multi-faceted mechanical contractor with a deep, century-long history of serving the region. Established in 1904, GSM has evolved from its early days to become one of Southern Minnesota's oldest and most respected service providers, offering a comprehensive suite of residential and commercial solutions. When you need a professional for a new water heater, a broken pipe, a faulty furnace, or even a new roof, GSM’s broad expertise means you can often rely on one trusted local company.
The Minnesota climate demands robust, dependable infrastructure for both homes and businesses. The plumbing and HVAC systems work hard year-round, making it essential to partner with a company that understands the unique challenges of our weather, from frozen pipes in the bitter winter to the need for reliable air conditioning in the summer. GSM’s experience, spanning over 120 years, positions them as experts in tackling these local conditions with effective, long-lasting solutions. Furthermore, their continuous expansion of services, which includes taking on plumbing and heating businesses in Gibbon and New Ulm in 2013, highlights their commitment to consolidating expertise to better serve the community. This holistic approach ensures better coordination and seamless service, whether the job involves a simple drain cleaning, a full boiler replacement, or an intricate commercial HVAC installation.
GSM, Inc.'s main office and showroom are centrally located, making them an accessible hub for customers throughout their extensive service area. The headquarters is in New Ulm, Minnesota, which serves as the base of operations for their dedicated team of professionals.
The primary New Ulm facility is situated at:
1500 N Front St, New Ulm, MN 56073, USA

★ 5★ 4★ 3★ 2★ 1If I could give 10 out of 5 stars I would. They were very timely in getting me fit into their schedule. Super impressed with the gentleman that came out and replaced our sink and our two faucet. He did a great job installing everything and did a fantastic job cleaning up after he was done. DEFINITELY will be repeat customers! Thank you!!!!!!
July 17 · Lauren SalisburyThese guys from sales to install were wonderful! I purchased all of my kitchen appliances here. They were willing to work with my timeline and corrected any issues on the spot!! I will buy from these guys again when the need arises! Jeanne M.
July 15 · Jeanne MoeriHad the ABSOLUTE best experience buying our fridge here (and microwave about 4 months ago). Dan came in on his own time on a Saturday when we were in dire need of a fridge and sold us one. I love buying local and this experience gave us all of the local hometown feel! Shout out to Dan and all the employees at GSM!!
June 30 · Lisa HackerIf I could give 10 stars, I would. GSM finished sewer replacement work on my home just today and I have never worked with a company as professional and responsible as GSM. Eric, Brian, Kyle and the whole team kept us informed as changes happened, were very respectful and answered all our questions. We loved working with them, and hope to use them for other services in the future. They also went above and beyond to replace our downstairs toilet that hadn’t been working. Great job!
April 17 · Jane WallaceSo my next complaint is when they were installing an unit in a new house next to mine, they regularly parked they're vehicles in front of my house and even parked a trailer in front of my driveway. I had to leave for work and Noone was around, so I ended up driving thru my grass to leave for work...
