This is ddnlj1's TrustRating, which is based on both the number of reviews ddnlj1 has written, and how many other people have voted those reviews as "helpful." It's a way to quickly to determine the value of any single review or reviewer, because it's based on how helpful ddnlj1 has been to the Kudzu community.
After calling two other electricians, neither of which even bothered to call back, I called Brown Electrical. They came out the same day, fixed the problem, and didn't overcharge. I'll use this company again.
