Who we are

From a single Omaha shop in 1899 to Nebraska's most trusted mechanical firm.

Grunwald Mechanical was founded in 1899, making us the oldest mechanical contractor in Omaha and one of the longest-running in the entire Midwest. From the very beginning, we built our reputation on technical expertise, honest pricing, and a commitment to quality that has stood for 125 years.

Today we serve commercial, industrial, and residential clients across Omaha and Lincoln, handling everything from emergency HVAC repairs to full design-build mechanical construction projects. Every technician is union-affiliated — Local 16 Plumbers Union or Local 464 Plumbers & Steamfitters — meaning you get the highest level of training and certification on every job.
