Peter came early on a Sunday evening within 10 minutes. He spent about 3 hours trying to locate what the issue was and why. He had to return next day to get what was required to complete job for another 2 hours. He put in a new circuit breaker, but there was still an issue, he stayed until he located what the problem was, turned out to be a loose connection in a ceiling light fixture. Could very well have been an electrial fire. Everything is working great now. My husband and I are 110% satisfied with Peter's work and wouldn't hestitate for a minute should we ever need more electrical work done. Very pleasant, meticulous and wonderful work etchics.
