"It went great! Our installer was fast, efficient, and focused on providing quality service. He made time for us on a busy Friday before the holiday and did it all with a great sense of customer service which is sorely lacking these days."

"Everything went great. Having repeated back-ups in the basement I decided it was time to do something. Black Diamond came out and put a snake camera down the access pipe while I watched. I was able to see the several places where roots had become an issue in the outside pipe. After explaining my options clearly I decided to have them install an outside access pipe to get to the "root" of the problems more easily. The pricing was fair and they came out exactly when they said they would - even though the temps were around zero outside! Despite the cold the work was done pretty quickly. The only drawback is a minor one. A mound was left behind at the dig site which I was told would settle after the ground thawed and perhaps some rains. It did settle a little bit, but there is still a good sized mound of dirt in my front yard. No big deal. I have had no plumbing issues since they installed the pipe and did a proper routing of the pipes. Overall great job.
