"Kevin, answered my call promptly. Responded to the issue the same day that I called him and he also arrived timely. The defective switch was fixed within 10 mins. and Kevin was on his way. I was so pleased with the service and I will definitely call K&K first, if I have any additional electrical issues."

"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.

"The service was stellar from the start. I contacted C. T. Smith Electrical and everything from explaining what I needed to the actual work being done was managed professionally. I provided pictures as well as the electricians came out to assess. The price was very fair for the jobs requested and even when there were some issues that required additional work, the additional cost was fair. They have no way of knowing what is behind the scenes until the start the work and I completely appreciated their assessment and the options available to complete the job. I am so happy with outcome. I will definitely recommend! Thanks C. T. Smith Electrical."

Electrical questions, answered by experts

The average lifespan of a home electrical system is anywhere from 30 to 70 years or more, depending on the type of system you have. Modern electrical wiring, like aluminum or copper, can last 50 to 70 years while older types may need to be replaced sooner. Additionally, circuit breakers tend to last anywhere from 30 to 40 years, while electrical outlets need to be replaced every 10 to 25 years. 

Unless you’re a licensed electrician, you should not DIY any electrical work in your home. Working with wires and electricity is potentially dangerous to both you and the structure you’re working on, and it could lead to house fires or electric shock if you’re not 100% sure what you’re doing. There’s a big difference between changing a light switch cover and rewiring an entire home. If you’re staring down a potentially difficult electrical job, give a pro a call.

A duplex outlet simply means that the receptacle has two plug-in outlets for two plugs. It’s a common design choice for homes. The two outlets should be wired identically during installation so the hot side is the same for both.

In the United States, home outlets support a standard 15 amps, but you can upgrade per outlet if necessary. Most single-family residential homes have a maximum overall amp rating, usually 100 to 200 amps. Very old houses may have less than 100 amps, but that’s rare. Large homes often come with amp services above 200 amps to support modern lifestyles.

If one plug in your outlet works but the other doesn't, it could be due to a few reasons. The outlet might have a loose or damaged internal connection on the non-working side. Another possibility is that the outlet is a split receptacle, with one half controlled by a wall switch that might be turned off. Additionally, debris or damage inside the non-working plug could prevent a proper connection. If you can't identify the issue, remember to prioritize safety. Replace the outlet or consult a professional electrician to ensure safety and proper functionality.
