While the cost seems steep, it was well worth the price! John the Consultant fully explained the test procedures & sensor equipment so you can see what they are checking, and trust the report. I was surprised to find that a high number of switches and outlets were arcing or not grounded, even though they were only a few years old. (Cheaper bulk quantities were purchased and I won't do that again.) The same electrician did the inspection & repair. I am more confident that nothing is unsafe behind my walls, and appreciate the generous warranty. I would also like to add that I worked for Birnie Electric 20 years ago, so knew they were trustworthy.
