"This was to install a standby generator. The advance planning was excellent as was the quality of the work. Customer service is outstanding. Price was high, however. LaPlante was the highest of 3 bids received. Nevertheless, I selected them because of their professionalism and customer service."

They were responsive, showed up when they said they would, and took the time to explain everything. I really appreciated the quality of their work and how easy they made the whole process. I would definitely recommend Hewson Electric to anyone looking for reliable electrical work!"
