Black Diamond Today

Black Diamond Plumbing & Mechanical, Inc. was established to serve McHenry County on June 1, 1999. Rick Sperando and Scott Underwood came together to found a plumbing and sewer company that would someday offer electrical and HVAC services as well. Our intent was to build a business that didn’t stop at just one thing, but instead offered our clients a broad range of commercial and residential services from one trusted provider.
