Precision Electric, Inc. is based in Mendon. Its website says Jack Grenga is a Master Electrician and Fully Authorized Generac Dealer, that the company specializes in generator sales, service and installation and services generators of any brand, and that it is also an authorized Interstate Battery Dealer. The company says it has been in business 39 years. In a 2026 review, a customer described service on the generator as "Ontime, Quick, Efficient, Friendly." In a 2025 review, a customer said they contacted Precision to install new outdoor lighting, replacing several old fixtures, and that the electricians arrived on time, worked neatly and efficiently, and took the old fixtures away for disposal. In another 2025 review, a customer said they left a voicemail and a call was returned minutes later, and wrote of a "great price." In a 2023 review, a customer said Precision Electric completed another job at their house and was responsive from the request to quote to the final work, answering all their questions.
