"After getting several quotes, last year we hired GenReady to install a house generator. Ed, the owner of the company impressed us from the start. He was knowledgeable and patiently explained the process as well as answering our questions. We knew right away that GenReady was the company for us. Lindsay kept us up to date as we moved along in the process. Our generator was installed last July. Andrew and his team installed the generator with expertise and efficiency. They took care to leave our house and yard spotless. Lindsay and Andrew were always happy to answer my questions and address me concerns. We’ve needed the generator only once (thank goodness) when our power went out due to a necessary power line repair after a car crashed into a utility pole on our street. When the power went out, our generator turned on within seconds. Our house was up and running for the four hours the line repair took, and if it weren’t for the blink of lights, we never would have known our generator was running. Every other week, our generator self tests for a few minutes giving us peace mind that it will be here for us if and when we need it. Just like the generator, GenReady is a company that runs efficiently and seamlessly. Just today, Lindsay called to tell me someone would be coming tomorrow to change the oil which reminded me that I am long overdue in submitting this well deserved rave review. Thank you to the entire GenReady team (and to Great White Propane) for all you’ve done to help us know we can weather any power outage."

Electrical for home addition or remodel installations FAQs

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.
