Customers say: Quality work

"Tim was highly professional and punctual in fact they showed up an hour early. I wasn’t able to be home while Tim was performing the work. But he kept me in the loop the entire time. He advices a better alternative to solve my electrical outlet needs. Tim was very responsive with addressing all of the questions I asked via text leading up to the install day. Over the last couple of years I’ve had electrical work done by three other electricians two of which were good. Overall the level of service Tim provided was above and beyond."

"Hired Precision Power twice to help with various electrical needs… rewired my kitchen and then again to help with the finish trim outs. We will continue to hire him. Currently just waiting for our new chandelier to arrive so we can have him back out again! Thanks for the quality work and dependability!"

"Randy was not only a knowledgeable and competent electrician, but an honest and ethically person. Our A/C and furnace appear to have no power. The main panel was looking pretty rough. Randy came by on a Sunday to take a look and quote a replacement. He inspected the system and concluded that it was working properly with cosmetic issues. He could have been dishonest, he wasn’t. He could have left, he didn’t. He moved on to the furnace and discovered a bad fuse, replaced the switch. It worked, but not the A/C. He could have left, but he didn’t. He went outside and tested the fuses and box, good. He unscrewed the cover on the unit and as he went to pull the cover the fan came on. What! An electrician with magical powers? One who can will dead appliances to life? A super hero? Maybe, but there was also a loose wire. Bottom line, Randy saved us a significant amount of money. Grateful for his service."

FAQs for electrical for home addition or remodel installation projects in Janesville, WI

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.
