When our Winchester electrical team arrives to perform your inspection, we will begin by taking a look at the electrical panel. This is the heart of your electrical system, and it contains the circuit breakers that distribute the power to all your individual circuits. We will make sure that your panel contains the appropriate number of circuits for your property’s needs and that they are all operational. If there are any problems, we will identify and correct them.
Other components we will inspect include:
If you suspect that you may have an electrical problem, there are a few things you can look out for to help you determine whether or not it is time to make that call to our electrical team.

Exceptional Customer Service EXCELLENT Based on 69 reviews Posted on Brian CaulfieldTrustindex verifies that the original source of the review is Google. Guy and Zach were great. Showed up on time, talked me through our issues and resolved quickly and inline with the estimate.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 Ting LeeTrustindex verifies that the original source of the review is Google. I've worked with Jeff and the JMR team many times over the past few years, and the crew is great! It is always a great experience; the team is always happy to help in a pinch, always having a great eye for detail, and providing recommendations when needed! They are always responsive too. I love having the opportunity to work with them on projects.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.Posted on Linda Levin-ScherzTrustindex verifies that the original source of the review is Google. We've a lot of electrical work done by JMR and they are excellent. They did the electrical for a new bathroom, upgraded our panel, installed outdoor fixtures, and took care of numerous other issues. They are prompt, professional, and knowledgeable. We highly recommend them.Posted on Michael HendrixTrustindex verifies that the original source of the review is Google. JMR Electric is the tops. Great communication, super organized, and really nice folks. We've used them for many different jobs, (swapping out a breaker, upgrading outlets) and are always happy.Posted on Jordan LiebermanTrustindex verifies that the original source of the review is Google. Highly recommend the folks at JMR! They do great work, are super friendly, and always on time (a rarity in the contractor business).Posted on Alex SchultzTrustindex verifies that the original source of the review is Google. We've had nothing but good experiences with JMR. We first reached out about a fairly significant troubleshooting/rewiring project about a year ago. Since then, we've gotten two more electrical projects done and both times we didn't hesitate to go straight to JMR again! We've always been pleased with the work experience and final product. The whole team is respectful and communicative - I particularly appreciate that Ed and Guy are always willing to answer questions and make sure expectations are clear. Pricing is clear and reasonable, work is tidy and well executed.
