DEDICATED TO YOUR SATISFACTION EXCELLENT Based on 75 reviews Posted on Roseanna CutiettaTrustindex verifies that the original source of the review is Google. Two professional, hardworking young men arrived at my house promptly, insisted on taking off their salty icy boots to not track it through the house, and then worked collaboratively and methodically to solve my problem. They even explained what was wrong and answered my superfluous questions kindly. JMR Electric should be proud.Posted on Joe HTrustindex verifies that the original source of the review is Google. Guy and the team worked effectively and transparently to add the new circuit to my basement. It was nice to have everything be up front and transparent and to know what to expect. I recommend working with themPosted on wesley donohoeTrustindex verifies that the original source of the review is Google. We've used JMR Electric for multiple projects around our house and they've been fantastic every time. Guy has done all our work from fence lighting installation, fixing indoor lighting throughout the house, outdoor camera installation, and repairing all our outdoor outlets. What sets them apart is how they operate. They're fast to respond and schedule, the quality of work is excellent, and they always walk us through different options and recommendations before starting anything. No surprises, just clear communication and great results. We're big fans of Ed and his entire team. We will keep calling them for any electrical work we need.Posted on Tom AngeloTrustindex verifies that the original source of the review is Google.

Thanks Ed for all your help!Posted on Jacob GellerTrustindex verifies that the original source of the review is Google. Ed Costa reached out almost immediately, was able to get something scheduled quickly. Their master electrician, Guy, came out with an assistant, they were on time, professional, knowledgeable, and kept me updated as to what they did or would be doing. I highly recommend them.Posted on Joe MariniTrustindex verifies that the original source of the review is Google. Amazing experience working with JMR Electric. From start to finish they did an unbelievable job and I would not hesitate to recommend them to friends and family. Thank you so much!Posted on Connie GaoTrustindex verifies that the original source of the review is Google. I hired JMR recently to electrify my detached garage and shed. JMR was very prompt in their communication and provided the estimate quickly after viewing the site. Their pricing was very reasonable and they were able to schedule me in quickly. The project required a large trench to pipe the electrical from the basement and a subpanel in the garage. The crew was very respectful and discussed the setup, wiring and outlet placement decisions with me thoroughly before proceeding with any execution. They were able to place the wiring and piping in discrete locations to minimize the visual cutter and brought over sufficient power for a future EV charger. Jeff (the owner) also stepped in personally to help with the job when some of the crew were out sick in order to keep the project on track. The inspection was completed successfully soon after project execution. I really appreciated the level of service and care from the JMR team and will be calling them back for future electrical needs.Posted on Mike RosenblattTrustindex verifies that the original source of the review is Google. JMR did a great job hooking my dust collector up to 220V through a relay attached to my control system for my shop. A slightly different project requiring collaboration that worked out great. Turnaround from request to completion was 1 week. Couldn't have asked for better service.Posted on Michael ChiuTrustindex verifies that the original source of the review is Google. Installed new electrical service for my 3-family + car charger. Neat work, completed quickly and good communication.
