"J&M Electrical did an outstanding job of installing a home backup generator. When the gentleman came out to do the onsite inspection and provide me with the results and options, it was a no pressure sales approach. He walked me through the entire process that was used to determine what size generator I would require in the event of a power failure. When he had left the house that evening it was not with an ultimatum of “You must let us know right away, or in the next 72 hours” type approach. In this case it was more along the lines of “Think it over and we are glad to have been able to present our product” Once we decided to have the generator installed the communication from the front office in regards to what was required from me and what the contractor would provide was excellent. Scheduling was easy and all that was discussed was provided on time and with no exceptions. The work crew was on time and cleaned up upon completion of the installation. Overall an outstanding experience and I would recommend them to anybody looking to have a backup home generator installed."

"Excellent customer service after the sale. Electrical component failed on a Sunday morning, placed a service call and a real person answered. Received a return call from a technician quickly, 30 minutes later they were in our driveway. Diagnosed the problem, completed repairs, very friendly and smiling. Total time from making the call to repairs being completed less than 90 minutes. Thatâ s INCREDIBLE in todayâ s world."

"Called and was scheduled for the appointment 2 days later. They called before coming over and actually arrived faster than expected. He was able to determine what was wrong with the door bells and fixed them quickly. He said he would have to trouble shoot the light fixture but suggested changing all 3 of the light bulbs. Well, that was all that was needed. Color me embarrassed. He asked if there was anything else he should look at, which was very nice. We will call them for any future electrical needs."

Electrical questions, answered by experts

You can add an electrical outlet outside by sending a wire through the wall from an existing interior outlet. Without having to open up walls, you can thread a new electrical cable from the existing outlet through the wall and to the exterior. You’ll need to cut a hole in the siding to place your new outlet. Ensure that your outdoor outlet is a GFCI outlet (ground fault circuit interrupter outlet) per the National Electrical Code. It’s best to hire an electrician to add an outdoor outlet unless you have previous electrical experience.

No. Do not use a 14-gauge wire on a 20-amp outlet. A certified licensed electrician would know that the National Electrical Code (as per Section 240.4(D) subsection 3) requires 14-gauge wires to be used with a maximum amplitude of 15. Therefore, you should only use 12-gauge wires on 20-amp outlets.

Baking soda is an effective fire reduction method. However, flour and baking powder are very dangerous around flames. Flour is flammable and it can also conduct electricity. The combination can cause serious injury from electrical shock and worsen the situation by adding fuel to the fire. Baking powder is also not an option as it's also highly flammable. 

You can determine whether you have a double-pole switch by examining its wiring. Unlike single-pole switches, which have two brass-colored terminals, double-pole switches feature four. These switches are typically only found near high-powered appliances such as electric furnaces or water heaters. If you’re unsure what type of switch you have, contact a local electrician to confirm.

Moving an electrical outlet typically costs between $25 and $300. The final price depends on several factors, including the type of outlet, the condition of your existing wiring, and the state of your walls. For example, working on exposed walls without drywall is easier and less expensive for an electrician. However, if the walls are finished, the cost may increase to account for necessary repairs afterward. It's recommended to consult a professional for a precise quote based on your specific situation.
