"Ken was very communicative and responsive (even answering texts while on vacation). He was able to fit us in fairly quickly and did a great job installing our attic fan. I would definitely recommend him to anyone looking to complete a similar project or for other electrical work."

"Frank and Anthony came out in the snow ahead of our scheduled time. Called before arriving and did an amazing job. I had a number of other contractors look at the job, had to called them several times just to get a quote. Schweiger Electric was able to give me a price over the phone, set up a time, came when expected,and then did more than expected. Super happy to have found this company, and glad to have finally found someone I can count on and trust for electrical repairs. Awesome experience and great quality of service."

"I had these guys install my Tesla home charger and they did an absolutely fantastic job. The work was super clean and professional from start to finish, and honestly turned out way better than I expected. At first I wasn’t expecting much because their text messages were a little short and blunt, but now I’m pretty sure they were just answering quickly while working out in the field. When Dave showed up at the house, he was like a friendly neighborhood dad—very down‑to‑earth and easy to talk to. The wiring is so neatly done that even the town inspector who came to sign off on the permit was impressed. I’m planning to move next year, and I’ll definitely be calling them again for the new place. Their price was very fair and actually cheaper than several other companies I checked with, and everything about the experience felt honest. Overall, it was outstanding service and I couldn’t be happier."

"Contractor and client provided light fixtures installed in various locations. Some openings needed to be made to access wiring. The openings were resealed, but more rework will be needed at a later date."

"Amazing service. Bernard and Devon came over and installed much needed electrical upgrades to my home. Came over at the time they said they would and completed the work swiftly. The price was more than fair and both electricians acted professionally."

FAQs for electrical for home addition or remodel installation projects in Mahwah, NJ

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.
