"I had the pleasure of working with Jacob for the installation of 2 ring flood lights at my home. From start to finish, the experience was top-notch. He arrived on time, was professional, and communicated effectively throughout the process. The installation was completed with precision and attention to detail, ensuring that the ring devices were properly aligned and securely fastened. The end result was exactly what I wanted - bright, well-placed flood lights that added both functionality and aesthetic appeal to my property. I would highly recommend Jacob for any electrical needs. He truly went above and beyond in delivering exceptional service"

"Black Diamond recently came out to do a competitive bid on installing a cleanout line, then doing a hydro jet and descale of the main sewer line in question. On top of being a few hundred dollars cheaper than the original bidder, they found that the original bidder had broken the flange on the toilet when they put it back on and overtightened it. Throughout the process everyone I dealt with was professional, easy to work with, and answered all of my questions. All of that would have been enough for a 5 star review; however, when they got here on the day of the job and went to locate the exact dig space for the line, they found I ALREADY HAD A CLEANOUT LINE (previously most of the estimates had been in ranges based on the original bidder's insistence that this job had to be done, but as it turns out it didn't). That saved me $4,500 on the job, which is pretty awesome! I'm using them for all of our plumbing needs moving forward."

We wanted can lighting in our guest bedroom but he said he could not do it with the current attic set up. So, he installed two new track lighting systems. He recommended LED. They do look better, but I'm overall not crazy about them. It basically took the whole day to install plus I had to go out and buy the "very expensive lights". Not necessarily his fault, but still disappointing.
