"Matt and his team were professional and friendly. He communicated well and was punctual. I had him put in an EV Charger out to my driveway and also needed to upgrade my electrical wiring which became more difficult than expected but Matt honored our agreed contract and had even saved us some money on figuring out a better solution. I highly recommend Matt and his team for any electric service."

"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!"

"Steve was very professional. He came out for a free estimate and was competitively priced. His team was neat and professional and they finished the job in a timely manner. The job was better than expected. We would use DES systems again in the future for our electrical needs. He was educated about our needs for the Tesla system and how best to install our supercharger. They were able to come up with solutions for our other electrical issues. We would highly recommend Steve and DES systems. Thank you."

"Chris has been to my home twice. The first time was to trouble shoot a circuit breaker that kept tripping, and he was able to isolate the problem to a faulty circuit breaker. The second time was to install a bathroom fan. Both times his work was great, and he was pretty easy to get ahold of, and was good about scheduling. I will definitely be returning to Chris again in the future for my electrical needs, and would absolutely recommend him to anyone else looking for an electrician."

"I hired David to install an EV charger in my garage and he did an excellent job advising me on the right approach to use, neatly installing the charger, patching up a wall, so I couldn’t even tell he needed to open up for access, and left the site in perfect condition. After such a + first experience, I hired David to come back and install an electric door opener at my house. Again, he didn’t disappoint with his fast and clean work, great follow up, and professional interactions. Highly recommend"

FAQs for electrical for home addition or remodel installation projects in Dover, MA

Because installing coax outlets involves working around existing electrical wiring and confirming proper grounding, many homeowners prefer to hire a licensed electrician. A professional completes the work safely, secures the line behind the wall, and ensures the installation meets local code, which reduces the risk of damage or future repairs.

You still need a coaxial outlet for most cable-based internet services. The modem draws its signal from a cable line that terminates at a dedicated wall jack. Once the modem is online, your Wi-Fi router can broadcast the signal throughout the home, so the outlet’s location doesn’t affect wireless performance. If an existing jack is damaged or in an inconvenient spot, an electrician can move it or install a new one to maintain a strong, reliable connection.

Coaxial cable loses signal strength the farther it runs. A 50-foot length introduces noticeable loss, and a 100-foot stretch can drop the signal by roughly 30%. A weaker signal can result in a fuzzy picture or slower internet speeds. To maintain high performance, limit cable length whenever possible, select the correct cable grade, and route it efficiently. If your layout demands an exceptionally long run, an electrician can install an inline amplifier to boost the signal and maintain picture or data quality.
