I had a GFI that started buzzing, which was very nerve-wracking! I found Mr. Larson on Thumbtack, and he called me right away. He was very professional and kind. I decided that if I was going to have one receptacle changed out, I would have the rest done, and have all the wires checked. He showed up on time and explained everything to me as he went. He also checked my breaker box to make sure everything was good there. The cost was VERY reasonable and they changed out about 25 plugs & switches in 2 hours. It gives me great peace of mind, and everything looks great!
