Black Diamond takes great care of all of our Properties across the McHenry Area!




We use Black Diamond for all of our Rental Properties (plumbing, electical, and HVAC) all across the McHenry, IL Area and have always had excellent service, quick response and repair times, professional and highly skilled employees. This week we have had two projects that were successfully completed. One was an AC hookup by Tim M. and the other was full replacement of an old glass fuse box to a full 100 amp modem breaker system that was completed by Tim W. I want to give a big “Thank you” to both Tim M. and Tim W. for doing an excellent job on our properties and I enjoyed working with both of them. I highly recommend working with Black Diamond and look forward to working with them in the near future.

Great Service




Rick, Black Diamond, was prompt, per quoted time frame, courteous and professional in his role. He was clear I’m his price quote and what that entailed. Rick resolved the problem very effectively.

So glad we called them! (Repeat customers)




I’m so glad we called them, because they diagnosed a plumbing problem we were not aware, and it would’ve been a huge and expensive disaster had they not caught it early! We are so very thankful that the people here take that extra step to tell you if they notice something that is a potential problem for the future. This is what we want in a company - trust, honesty, and quality work. That’s what we got! We will hire you for any future work. Thank you!

Nick is a Friendly, patient, and informative sales rep. David installed the new HVAC unit quickly and correctly. Alex completed the Aeroseal quickly as well and was in contact with me via text, email, and phone throughout the process. Even forwarded me before and after photos and stats of my duct work. The overall parts and labor for the whole job was expensive however.

Great Job




Jorge arrived exactly on time. After explaining the policy & price, he got right to work replacing 2 older toilets. He finished the job in a timely manner. The results were nicely done. Jorge cleaned up his work area, removed the old toilets & the boxes for the new ones as well. I could not be more satisfied .
