We had some issues getting our bathroom fan and light on and Jonathan was able to make it over the next day in the morning to get everything sorted out. He was very professional explaining what was going on and what he was going to be doing. He was friendly and got the job done in no time. I was very satisfied with the service, I will definitely be calling black Haak again for any future services I may need.

John Burkhart Jr was my plumber. He was very knowledgeable and has years of experience. John took the time to explain the issue and gave me my options. I'm very happy with the service repair and it was done the same day! Highly recommend this locally owned company. Support our local businesses 💯

I had 2 separate plumbing problems in one day! Each of the 4 gentlemen who came out were incredibly helpful. Esteban and Cooper were phenomenal! All things fixed in no time! The middle aged Navy Vet with Cooper was a wealth of knowledge. Thank you and your son for your service!🇺🇸 I paid more than I expected but they were there quickly!
