Ralph Didomenico is a Walpole electrician people call when the job can't wait. In a 2022 Thumbtack review, a homeowner who had been let down by other electricians — "everyone else was a no show or too high" — said he came within an hour, fixed the problem and charged a fair price. On Thumbtack he holds a 4.9 from 53 ratings and has been a Top Pro since 2019; HomeAdvisor shows a 5.0 from 4 ratings for Ralph DiDomenico Licensed Electrician, LLC, which describes itself there as Didom and Son. His Thumbtack profile says he is a fully insured electrical contractor with over 16 years of experience in residential and commercial wiring. BuildZoom shows 69 permitted electrical projects since 2020 across Boston-area towns. The written reviews describe hands-on electrical work. In a 2022 review, a homeowner hired him to update the outside meter and breaker panel and install ceiling lighting, and he moved the job up a week to fit their contractor's schedule. A March 2023 customer described a short-notice visit for a tripped breaker, a ceiling fan and loose wiring; an April 2023 customer had a fan installed and called his rate affordable next to other licensed electricians in the area. In a 2020 review, a customer said he found more problems in their panel than they had called about, then walked through each one so they knew what was urgent and what could wait. A 2018 customer had a number of electrical issues repaired in a Providence apartment in under 24 hours. The most recent review, from October 2025, says he solved the problem and suggested further electrical improvements. One thing to know: the Massachusetts registry lists his electrician licence #55470-EL-B, held by Ralph Didomenico, as expired.
Ralph solved my problem and was very reponsive to my issue. He also had great suggestions for electrical improvements. Ralph was wonderful to deal with. I will definitely call him again.
Ralph is very knowledgeable and helped us to figure out the issue and fixed it in a timely manner. His work ethic shows that he knows what he is doing. Will definitely use him moving forward. Highly recommended!!
Ralph was great! He was responsive from the start when I initially contacted him, and was very easy to coordinate with. We had a fan installation project. His rate was affordable compared to other licensed electricians in the area. He was polite and efficient and I’d definitely hire him again.
Ralph was responsive and very efficient after coming out on short notice to help us with numerous electrical issues (tripped circuit breaker, ceiling fan, loose wiring). He did great work and showed up the other electrician’s shortcomings. I’m going to have him come out and fix any other issues as well. He knows his stuff and don’t hesitate to hire him!
I highly recommend Ralph Didomenico. Hired him to change/update the outside meter, breaker panel and installed ceiling lighting. I needed the work done a week earlier due to contractor scheduling and he was able to accommodate without issue. Ralph is very personable and the work was done perfectly. What else could you ask for! Here are some before and after photos. Last 3 are the "after" photos
