"Jason and his team with Cotti-Johnson did an excellent job updating our electrical boxes, installing the washer/dryer hookup, and getting us setup with a generator! Sam, our assigned electrician, even took the time to go through the entire operation of the generator from A-Z. I would definitely recommend them for any electrical work!"

"Tim P, Generator Advisor, visited our house and gave on the spot estimatesâ ¦..he was GREAT. Licensed Electrician who knew his business and was easy to speak with. Timely communications and responses to text messages! Tim was helpful answering questions after the generator was installed. We talked to 5 Generac dealers and a Kohler dealer. Cotti-Johnson had the best pricing in the South Shore area. We highly recommend this company. If you are thinking about buying a standby generator, Cotti Johnson is the company to callâ ¦..Art V"

FAQs for generator repair projects in Dennis, MA

Always start by confirming the pro’s license number, insurance coverage, and experience level. Visit the electrician’s website, scan recent customer reviews, and verify credentials with your local labor department. Request proof of liability insurance and at least two references that you can contact. These quick checks take only a few minutes but go a long way toward ensuring safe, code-compliant work and protecting your home in the event of an issue.

Grouping several electrical jobs into one appointment means you pay a single service-call fee and one set of travel expenses. Instead of asking a pro to return three separate times for outlets, switches, and fixtures, have everything tackled in one visit. The electrician stays productive, and you avoid extra trip charges, often shaving a sizable chunk off the final bill without compromising quality.

DIY electrical work can be dangerous and, in many areas, illegal without a license. One miswired connection risks shocks, fires, or expensive damage. Licensed electricians carry the right tools, follow local code, and know how to shut down power safely before they start. Hiring a pro may cost more upfront, but it protects your home, family, and insurance coverage in the long run.
