Critical
“Back in December 2024 I had my gas valve replaced by Black-Haak. They came out right away with many notifications, got the job done without issue, and they offered me a free cleaning. I took them up on the free cleaning a year later in December 2025. The same technician was back again, she said it was fine at the moment but noticed a potential crack inside that could cause me issues in the future. Now March 2026 I …”

“Black Haak began in this very house I now live where Floyd Blackie once lived. His work shop was our garage. I still have Black Haak serive my heating. They are a little bit more expensive, however, their work is very good, and warrantied. I prefer to avoid problems calling someone after hours spending more money because the job was not correct. Ive had some wiring too and I was pleased with that work as well.”
“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 💯”
