It always happens at the worst possible moment…

  • The retail store where sewage odors drive customers away during the busy weekend.
  • The medical facility where patient safety is compromised by sewer line backups.
  • The restaurant that can’t operate because the kitchen drains won’t clear.

And suddenly, a sewer problem becomes a spotlight you don’t want on your business.

Real Talk from Real People

Whether it's facility managers recommending us to colleagues or our employee-owners who've been with us for decades, the professionals who know us best understand what sets us apart.

  • "I spoke to Tom about some work I was considering having done at my home. I was very impressed with how knowledgeable, honest and upfront he was when he provided options and went over the pros and cons. Other companies I've called wanted to charge me $50 just to give a quote. If you need work done at your home I recommend you call Tom at Midwest Mechanical."

  • "Midwestern Mechanical's BIM modeling capabilities saved our hospital project significant time and money. Their virtual construction coordination identified and resolved conflicts before we reached the field, and their fire protection design expertise ensured we met all healthcare facility requirements. The entire process was seamless from design through completion."

  • "When our water heater died on a Sunday morning with three kids needing baths, they were at our house within an hour. The technician explained everything clearly and had us back up and running the same day. Being employee-owned really shows—they care about our family like their own."

  • "When sewage started backing up into our basement, we were panicked. They were here within 45 minutes, even on a Saturday evening. The crew worked through the night to get everything flowing properly again and cleaned up everything perfectly. You can tell they really care about doing things right."

  • "Our water pressure had been getting worse for months, then one morning we had almost no water at all. They diagnosed a collapsed water line and had us back to full pressure by the end of the day. The crew was professional, clean, and explained everything clearly. Our water has never worked better."

"Reliable sewer service, from the team
businesses across the region trust."
