Typical Greater Boston range for this kind of work, from regional averages — not a quote from JDO Electric. Use it to sanity-check bids, then get the real number in writing.
Standard receptacle swaps — a new dedicated circuit is a bigger job ($350–$750).
Flush mounts, pendants, chandeliers — hung on existing boxes.

JDO Electric is Jim De Oliveira's Somerville-based electrical operation, and the through-line across twenty Google reviews spanning 2021 through this spring is remarkably consistent: every single one is five stars, and the same specifics keep repeating — fast callbacks, careful work, fair pricing, and Jim showing up himself. The reviews describe him handling everything from routine panel upgrades to genuine emergencies. In a July 2025 review, a homeowner described outlets failing and flickering over a holiday weekend — Jim was the only electrician among several contacted who called back, within the hour. In a November 2022 review, he diagnosed and fixed a short circuit in about an hour on a problem the customer had been told could take several hours. He's also repeatedly the electrician of choice for gas-fireplace and built-in installs — reviewers from 2021 through this year describe him wiring gas inserts, protecting rugs and flooring before starting, pulling permits, and flagging issues that would trip up a town inspector before they became a problem. Customers also describe him explaining the work as he goes rather than just doing it — walking a layman through code-compliance choices on a condo GFCI upgrade in a 2024 review, patiently answering questions during a 200-amp panel and multi-outlet install in a 2023 review, and pointing out future maintenance needs without being pushy. Several reviewers mention using him more than once, and at least three separately note that the town inspector complimented the work. Both the BBB profile (A+, accredited since 2015) and JDO's own site describe a long track record, though they don't quite agree on the number — the BBB lists 31 years in business since 1995, while the company's site says 25. The BBB profile also lists a Wilmington address rather than the Somerville one seen elsewhere, though the phone number matches across sources. For anything from a stubborn short circuit to a full panel upgrade, this is about as consistent a record as they come — the main thing worth confirming is simply availability, since demand for one guy with this kind of reputation tends to run ahead of his calendar.
I hired JDO Electric to install 3 pendant lights above my dining table and 2 ceiling fans in bedrooms for which there was no electrical wiring. Jim and his associate Austin did a phenomenal job. Great communication, fantastic service quality, and fair pricing. Really pleased with the outcome and would happily hire JDO Electric again!
Jim from JDO is easy to communicate with over email text and phone. Fair prices and easy to schedule with. Over 2 sessions he replaced all our primary room lights, including the dining space which required a new ceiling electrical installation. Jim patched up the old location and now we have a light actually centered above our dining room table! My wife and I love the finished work and will be using JDO in the future for our bathroom fixtures!
Jim did the electrical for a fireplace/built-in cabinet project. He installed new LED overhead lights and fan in the vaulted ceiling, changed out all the outlets and put in custom cabinet lighting which came out amazing. Jim's communication was immediate and continuous, always keeping me updated to the next steps of the project. He always showed up on time and was professional. You can't go wrong hiring Jim for any of your electrical needs!
We were looking to install an electric fireplace and had three electricians look at the work to be done. They were all qualified electricians but Jim De Olivera was a step above the others. Jim was recommended to us by Hearth Works Fireplace Center (Mike) in North Reading. Jim was excellent, professional, punctual with follow up skills and respectful of our home. The work was meticulously done, no dust, no drama. Jim and his associate Austin were excellent and I will continue to utilize him when necessary. His approach is simple “Customer First “ Call Jim De Olivera for your electrical needs..
I rarely write reviews, so please bear with me. Long story short: My best experience with any electrician has been with Jim of JDO Electric. On Saturday, July 5th of the holiday weekend, my home’s electrical system started to fail. Some outlets worked, others were completely out, and a few flickered on and off—creating a strange and somewhat frightening situation that needed immediate attention. I reached out to several electricians I’ve used in the past. Only Jim returned my call—within an hour of me leaving a voicemail. After I explained the issue, he quickly put me at ease. He said there didn’t seem to be an imminent threat to the house and promised to come by within the hour. Upon arrival, he diagnosed the problem and explained what was causing it. Jim was able to provide temporary relief by restoring most of the 110v service. It turned out that the electrical load in the house had become too much after we installed a central AC system and an EV charger in the garage. Jim recommended upgrading to a 200-amp service. This involved not only replacing the entire electrical panel but also extensive rewiring—inside the house, at the meter, and the connection to the utility pole. Throughout the process, Jim and his assistant Austin were excellent at keeping us informed about what they were doing and why. Their clear communication reassured us that everything was moving along smoothly. They worked diligently and professionally, kept the work areas clean, and were respectful of the fact that we were working from home. Even with the outdoor work requiring them to endure extreme heat, they pressed on and got the job done. The entire upgrade took about a week and a half, and we couldn’t be more satisfied with both the process and the final result. I wholeheartedly recommend JDO Electric to anyone looking for a competent, experienced, professional, and reliable electrician.
