"I have used these guys for six or seven projects now and they are amazing. I have used them both for heating and cooling and their electrical services. John and Brian are amazing electricians and more importantly just great and fun to be around people. I would recommend them to literally anyone and I trusted them to work on my parents home. My lifelong contractor told me that they were the best electricians he's ever worked with. I really cannot sing their praises highly enough and if you have any hesitation about them I hope my review is somewhat helpful in allaying them. Their work quality is top notch and they're professionalism cannot be beat."

"I am certain you can't find a more skilled, honest and fair electrician and tradesman than Gary Fisher and his team is wonderful. I received a quote from another electrician for over $20,000. Gary and his team actually did more work from me at about a third of that $20,000 price I got from a different electrician."

"Ron and his team have been a real pleasure to work with. I had water damaged in my master bath that turned into a master bedroom floor replacement, a lower level drywall replacement in 3 rooms and a complete master bathroom remodel. Ron worked with me through every step of the renovations. From initial inspection to renovation ideas to improve the functionality of the bathroom. Put me in contact with a great design specialist for materials for the bathroom. I have worked with other teams before and they can not compare to the high quality and professional attitude of Ron and his team. I am a bit of a perfectionist and noted things that I wasn t sure about but Ron s team or Ron would quickly answer my questions or work with me to improve the design and/or the things I wanted done differently. His team noted small things around the house and took care of them without asking or adding cost to the project. I had a few pieces of drywall tape in other rooms that had started to work there way off and his guys redid them and paint the area. Ron and his team have made this project very easy for my family and I. They are efficient and have a true art for their trade. They produce a high quality product. They always maintained a clean environment while they are working. Ensuring that they clean up their work site at the completion of everyday. Respectful and polite during every conversation. Work with me to answer my questions and fix the issues I note throughout the project. Returns phone calls quickly normally within a few minutes. Or he will come over to the house to answer my questions in person. And show me his thoughts so we can brainstorm the best results together. I would HIGHLY recommend using them for any home improvement project you may have. I will definitely be using them again when we decide to move onto the next home improvement project. Great friendly company of professionals."

"Highly recommend! He is always on time, professional, and really knows what he’s doing. His pricing is very reasonable and fair. What I appreciate most is that if something unexpected comes up while he’s working or something doesn’t go as planned, he is quick to communicate, explain what’s going on, and come up with a new solution. He doesn’t leave you wondering what’s happening and always makes sure the job gets done right. Very reliable, knowledgeable, and trustworthy. I would definitely recommend him for any electrical work!"

"He's been the best electrician I've ever dealt with. I was extremely impressed and shocked. not only did he do a phenomenal job, but it's immaculate. There is not a little bit of wire sitting standing anywhere. He cleaned up, he was lovely, he didn't talk much, but you know, he was very busy all day because our entire electrical panel had been blown out from that storm. This is the 1st time since July 4 that we have not been sitting in our house with the lights flashing on and off."

FAQs for electrical for home addition or remodel installation projects in Haddam, CT

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.
