Sean is a great Electrician and his employees are just as gifted. They handled all of our electrical needs for our new home. Highly recommend for any of your electrical needs!
Half the power to my home went out due to equipment failure in my meter box. CMP came and did a temp fix, but was adamant that we needed an electrician the following day. I probably called at least 10 electricians this morning, most didn't answer, and the few that did answer were unable to help. I was mentally preparing for my house to be without power at least for another day. Then I called McCarthy Electric. He answered the phone right away and was at my house within an hour of my phone call. They completed a huge amount of very necessary work in a single day, all for a very reasonable price. I won't be calling anyone else for electrical needs moving forward, these guys were the cream of the crop.
Got knob/tube wiring hiding in your walls or worse- exposed? Honey-do list getting back logged to upgrade switches safely? You’ve come to the right place- Mr. McCarthy is efficient, seasoned professional and great company. 10/10 would recommend and just kicking myself I hadn’t reached out earlier.
I cannot explain how happy I am with this company. I gas some serious issues that were immediately taken care of very professionally. Would not hesitate to recommend this company. Simply the best.
Highly recommend. Have cslled a few times now on an emergency basis. Was at my location quickly and always quick and highly efficient with work done. Excellent job each time. Highly recommend. Wether job is big or small. Excellent work.
