Thumbtack customerOct 2026

Angel did an outstanding job installing my new EV charger for my Rivian R1T! The installation on the side of my home was clean, professional, and exceptionally well done. His attention to detail and quality of workmanship really stood out. It’s clear that Angel takes pride in his work and makes sure everything is done right. I couldn’t be happier with the results and would highly recommend him to anyone needing electrical work!

professional very easy to work with

Thumbtack customerDec 2025

I had a nearly impossible outlet to reach and I wanted to have it relocated without destroying the wall. The guy came and was professional, on time, knowledgeable, and easy to communicate with. He had to come in/out of the house multiple times and was very respectful and polite. Long story short: this guy knew what he was doing and did a better job than expected with this outlet situation. I would absolutely hire again. 10/10

JMJ Electrical Services LLC installed a NEMA 14-50 outlet in my garage. Since my circuit breaker is on the opposite side of the house, the technician ran a new line all the way across. He did a neat, professional job and carefully patched up every hole he made.

Needed a dedicated power source for my treadmill and the team came out the next day and got it done pretty quickly.

I was conflicted writing this review. But this needs to be seen. I needed a 30amp outlet installed in my garage to power my camper. Initially I thought I had worked with Angel before at my previous house to get this work done. After this, I realized it was not him because the other guy did it correctly the first time. First off, knowing that it was going to power a camper/rv, an electrician should know the proper voltage. I am not an electrician, so how would I have known that? All I knew was 30amps. So as a customer consulting and learning from a professional, I accepted a 240v 30amp set up. The guys finished quickly and did their best with cable management. Minus the fact that the wire was just ziptied to the existing conduit they at least protected the wire going through the walls. After they had left, I noticed my surge protector stating "open neutral" after going back and forth on the phone with Angel, he stated that the outlet doesn't have a neutral line (because they put in 240v) and maybe the receptacle is old. I told him that I don't think this should be 240v (per google it should be 110-120v for a camper). I told him can his guys come back and change this to 120v. After he said "but you said 240v" made me feel like I was getting blamed for this mistake. His guys came back the next day early in the morning when I was told "I don't know when they'll be able to come but probably after 2pm". The switched it to 110v and then replaced the old receptacle stating "this is what was wrong". If it was wrong, why did you guys continue using it and why was it not brought to my attention from the beginning? The best part is, I am certain they plugged in my camper without my consent because when I plugged it in myself, my camper stopped working. Because of the 240v, it fried the convertor and now that needs to be replaced. They charged me $980 for 110ft of wire using pre-existing materials minus the wire. They came back and charged me another $110 to move from 240v to 110v and replace the receptacle ($7 at home Depot). He stated his work is "under warranty" but why did I have to pay more? I thought I was going to use them again for a few more projects but this will definitely be the first and last. Make sure if you use him, get whatever he is going to work on written somewhere. A phone call isn't enough to document work that will be done. I would've given 2 stars but I can't say their work was poor.

These guys did a lovely job. They switched out an old porch light with a new one. It looks great. I’m really happy with the work.

Licensed electrician. Installed a 240v 50A outlet for my Tesla mobile connector. Provided me an in person quote on Wed and installed the outlet on Sat. His was best value of 3 quotes I gathered before hiring. Very responsive to all of my questions. Ran the cables neatly along existing conduits so completed job looked professional. Even cleaned up the area afterward. I will definitely use him next time I need electrical work!

Angel responded to my request to move light switches and install sconces within minutes of my request on thumbtack. He and his team were able to complete the work immediately and they did an great job! They even patched and painted for me. I would gladly use them in the future.

Coren A.Oct 2021

I m very happy with my recess lights. They came in with their own product. I didn’t have to buy a thing like other estimates requested. They did the work, moved and put back furniture, vacuumed, swept and most importantly they patched the small hole they had to make to install. I will use them again with pleasure.

We acquired Angel's services to replace the electric panel in our home which was from the 1960s and used screw in fuses. He replaced the panel with a updated panel. (See attached photos) Angel and his team were courteous and professional. They got to work immediately upon arrival and worked well as a team. During the estimate meeting, Angel didn't push us to get additional work done which we appreciated. I will definitely refer Angel to my friends and family who are in need of electrician services.

Pamela B.Aug 2021

Great service and professional staff. Replaced old lights with new LED lights and installed light fixture and wiring for lights on my deck! I will hire again for additional work.

BUYER BEWARE, I DO NOT RECOMMEND THIS COMPANY!!! Angel came to my home to install electricity for my sauna in August. This unit required its own breaker due to the amount of power it would pull. I asked him what type of warranty did his company have. He stated that he guarantees his work and if we every had any problems just call him because he lived close by. We did not realize that the sauna didn’t have its own breaker until a few weeks ago. I contacted Angel and explained the problem. He said it wasn’t an issue but he wouldn’t be able to come on September 13th when I contacted him because he was in Richmond, VA. He stated that he could do it the following week I said no problem. I followed up with a text message and called to inquire when he’d return because the sauna is used to help me treat my Fibromyalgia. To date, he has not returned my call or text. My calls go directly to voicemail. I would not recommend his services. If you decide to go with this company please do not pay cash, which is his preferred method of payment. Now, I am forced to find someone else to complete the job properly and will file a formal complaint against this contractor and company with the county and contact my attorney. Unethical people is an easy find. Finding a company to stick by their word after the job is complete is another.

The work turned out to be more complex than originally expected, but J&M tackled it with gusto and a positive attitude. They did a great job installing recessed lighting and recessed outlet. The team showed-up on time, were charming and professional. The quality of the work was perfect, and my wife's reaction to the final product was "wow, it looks great!!" Would definitely use again.
