Outstanding electrician!

We called for emergency service and Tim was dispatched to our home. Tim called while enroute to let us know his arrival time. Within minutes of arrival he was able to assess the situation and fix the problem. Tim is very competent and makes his customers feel confident in his skills. He did a great job and is an asset to Black Diamond.

Not Happy

Service tech removed SafeGard filter and told me to get a new one and install it myself. After two trips to Menards I still haven't found the correct filter. For $6000 I think he should've installed a new filter.
