Another electrical company provided me with an estimate I thought was very high. I called Ungerman - they came the same day, got on top of the job, diagnosed the issue, and resolved it in 90 minutes, at a cost 1/4 of the other estimate. The electricians were knowledgeable about my type of house (1920's construction with three generations of wiring), hard-working, and easy to work with. I am a very satisfied customer.
