"Mario installed my Tesla wall connector was very flexible. When we decided to wire the connector to an oven plug instead of direct wire, he left to get the plug himself. Great service"

"I was referred to Kolb Electric by my home warranty service. There were two issues, both in the bathroom: 1. The light fixture did not work. I had changed the bulb but still no light. Could not determine the issue on my own so I contacted an electrician. 2. One of the two plugs on the outlet did not work. The latter issue was relatively easy to resolve. The repair person happened to have a GFI receptacle and was able to replace. He noted that the cost was normally $30 + tax for the part but he did not charge me. The reset had broken on the other one. With the former issue, the technician was taking a very long time (more than 30 mins) to diagnose the problem. His conclusion was that i needed a new fixture entirely. The one I had was a T12 ballast fixture and he recommended a T8 ballast fixture. I asked him to explain the rationale as well as the difference between the two. He didn't provide a very thorough or clear explanation, except to repeatedly say that I needed a new fixture. In reality, what he was recommending was a new striplight--not a new fixture. [Note: I purchased a new T8 light strip from Amazon for a whopping $16.45.] When I asked if he was able to make this repair, he noted that he had to contact my home warranty service to get approval. I could not recall immediately if my home warranty covered parts, etc. I looked through my files for a copy of the policy while he spoke with the home warranty service via phone. He shared with me that he'd now been at my home for more than an hour, and there would be charges for subsequent time. [Note: He was on the phone with the home warranty company from 8:49 am - 9:20 am.] I asked him how he'd calculated that, since it had been less than an hour, and he said that he included the time it took him to find parking. Even now, nearly two years later as I write this, I still can't believe he actually said that. If every repair or service person charged their customers in DC for time they search for parking, no one would ever be able to afford a repair service. This is a major metropolitan city and you're arriving during the AM rush hour (arrived at 7:40 am). As he spoke (allegedly) to the warranty company, presumably his dispatcher/supervisor and me, he kept changing the cost to stay--from $246 to $305 to $185 (for the fixture alone) to $270. At this point, I decided to wrap up our interaction, and told him I'd be in touch if I needed him (which I never would). I gave him a check for $75--the cost per the warranty company for the visit. In the end, I never called him or Kolb back. It took 2 more electricians to diagnose the problem (see my POSITIVE review of A Action Home Services). In the end, it wasn't the fixture at all. A neutral connection had to be repaired. Once that was fixed, and a new bulb installed, ta-da: light! I'm being generous with my rating mostly because he did fix the plug.

"Simply amazing from start to finish! I can't say enough nice things about this company or the people that I dealt with. They were all professional, friendly and they did great work. They called me just minutes after I clicked their name on Angi's List and had someone out to give me an estimate and had my appointment date set in record time from most companies that I have dealt with for home improvement. I hate having people in my house working but I felt totally comfortable with them. The work they did was exceptional. We got a new power box (breaker box - whatever it's call) and a new meter and a couple of new outlets put in. We also got new smoke detectors throughout the house. They had to work around some issues and relocate a bit of pipe from out water filter system that was in their way. And they just took care of it without any complaints. I didn't have to do anything. They took care of it all and had the inspector come out and get it approved. I feel safe in my home now. I highly recommend this company and I will be calling them for any future electrical work that I need done."

"Exactly as expected - PERFECT. I have been using this electrician since I bought my current home 22 years ago. ALWAYS get fast, responsive, great service. I wish every contractor I have used was like Stephen Palmer Electric. Every electrician sent out has been polite, honest, professional (and they get the wiring done right at a very fair price)."

"The electrician was able to resolve an issue with a dimmer switch that had been improperly installed by the builder. This caused any switch to be installed to eventually short out. He replaced two switches, a dimmer and 2-way switch in the basement of my townhome. The replacement was quick and efficient and the electrician was very professional. I will definitely use their services again, if needed."
