"Hank was a life-saver! We needed an estimate to do the job while negotiating the price of the house. Hank understood the urgency, was right there, and produced a very accurate estimate for a job of uncertain parameters. We closed on the house, and continued to live 1.5 hours away while Hank did the work on the house - he had to make many decisions himself, and all were the right ones. He did the job with as little damage to walls/ceilings as humanly possible due to forethought and expertise. We moved in, and the most frequent comment as we got settled was "How 'bout Hank? That is exactly where the outlet should be!" or "we didn't think of that, but Hank did!" A true professional, knowledgeable and thoughtful, respectful of old houses - we highly recommend Marsh River Electrical!"

Customers say: True professional

"Very professional and efficient. I felt that communication was clear, and he made sure that I was 100% happy with the job before he left. Everything was explained clearly to me from start to finish, and he guided me on purchasing my EV charging box. I would definitely hire Jeff again for any future electrical work."

"Roy and his team did a great job! They are professional, timely, thorough, and have an eye for detail. We bought a house that had a butchered, antiquated electrical system that was unsafe and chaotic. Roy and his team stepped in and not only sorted out the mess but put in its place a state-of-the-art electrical system that has been greatly simplified, and made safe and convenient (Roy spent time walking through the house with me talking through placement of switches and other features that ensured we had light in all the right places and flows perfectly with day-to-day use). Hire RGS, you'll be glad you did!"

From start to finish, Haendley was extremely professional, knowledgeable, and detail-oriented. He took the time to explain the process thoroughly, ensuring I understood the work being done. His craftsmanship was top-notch, and everything was completed efficiently, on time, and within budget. He also maintained a clean and organized workspace, which I truly appreciated. It’s rare to find an electrician who combines expertise, professionalism, and excellent customer service so seamlessly.

FAQs for electrical for home addition or remodel installation projects in Portland, ME

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.
