Typical Greater Boston range for this kind of work, from regional averages — not a quote from PROVOLT. 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.

Worked with Wagner on an issue with our breaker and an outdoor outlet. He helped us through the problem same day, and was very affordable as well. Highly recommend.
I called to get our 220V outlet checked to see if there was a problem. You folks showed up, checked the outlet, which was fine and you did not even charge us for the visit. You are now in our contacts list as our local electrician!
Wagner has been outstanding to work with! We are new homeowners and have been overwhelmed by the choices and updates we have needed to make. Wagner has been so patient and has helped us really think through what makes the most sense for our house rather than just trying to sell us on everything. He is trustworthy, his work is excellent, and his pricing is fair. We highly recommend Wagner and his team!
We’ve been working with Wagner and Provolt on several different projects in our new home. First and foremost, their professionalism is unmatched. We communicate directly with Wagner and he’s always responding quickly. Second, their work is outstanding. They always do a great job and they’re extremely clean. Wagner goes above and beyond and has helped us in several emergency situations. We’d recommend Wagner and Provolt to anyone and will continue to work with them in the future.
Wagner Rosa came to our home as the electrical subcontractor for Ulta Home Improvement. Wagner is very professional, personable, friendly and (most of all) a competent, reliable, hard working master electrician. Over the past several years, I’ve sought out the services of a few experienced, recognizable and respected electrical contractors who provided services to solve our issues. Despite those previous positive, successful experiences, from now on Wagner and his company Provolt, will be my go to for any electrical services or repairs. I highly recommend that anyone in need of electrical repair work, services or upgrades, contact Wagner Rosa at Provolt. I’m sure that you’ll be pleased with his expertise and service.
