Awesome Service of course

Reviewing how great Black Diamond's service is, is almost boring. Yes, they were prompt, professional, polite, neat, and thorough. *yawn* What else is new? Seriously, they are great, and I call them for everything.

The Best Service encounter I have ever had !!!!!!!!!!!

The conundrum here is that having your sewer back up into you home is an awful experience. But I find that this encounter with Black Diamond was a great encounter !! I have never met men with such a high standard of professional integrity in any service episode in the past. I would recommend Black Diamond and specifically that crew to anyone, any time for any plumbing needs. Black Diamond is very fortunate to have these men representing them in the field.
