Typical Greater Boston range for this kind of work, from regional averages — not a quote from TIM GROH ELECTRICIAN. 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.
Estimated range
$530 – $1,100

I found Tim Groh to be a most competent electrician who patiently answered all our questions and installed our generator as promised. He coordinated with the town on any permits and our generator was up and running smoothly in time for the heating system. Tim is enthusiastic and capable and we are pleased with him and our generator. We have a service contract with Tim and know he will take care of our needs. I recommend him to all.
Tim was great. He was prompt, professional, knowledgeable and a friendly funny guy to work with. Somehow we didn't need the generator during the worst winter ever, but it was comforting knowing it was there. Highest recommendation for Tim Groh!!
Tim Groh installed a Gernerac generator at my home residence. He is an expert electrician with a specialty in installing alternate power supply, automatic starting, natural gas ((or LP) fed generators. He was courteous, respectful, and handled all the details of the generator size needed, delivery, movement of the generators to the installation site at my home, installation, and testing of the generator. I would recommend him highly to anyone considering installing a standby, automatic starting generator at their residence.
The entire process of researching, selecting, and installing our whole house generator was a pleasant one, thanks to Tim Groh and his knowledge, professionalism and courteousness. Tim answered all of our questions and was very clear on exactly how the installation would be handled (cost and timeframe, etc). He showed up on time, he and his crew were respectful of my home, and the job was done exactly as described. I would recommend Tim to anyone interested in having a home generator installed.
