Electrical for home addition or remodel installers in Emeryville
We got our start in real estate, fixing restaurant equipment, lighting, and heaters for our business tenants. After four years, we started taking work as an independent general electrical contractor, and today, do a range of commercial and residential work including panel swaps, electric vehicle chargers, rooftop A/C units, etc. for single-family houses up to apartments, hotels, and strip centers. Our friendly and affordable techs are happy to install a new light over your kitchen table, but we also know our way around restaurants, daycares, and factories: three-phase wiring and motors, variable frequency drives, transformers, machine tools, and low-voltage communication and signaling (e.g. Ethernet). Prior to Shortbar, our owner worked nearly two decades developing software in Silicon Valley, and holds a master's degree in electrical engineering from the University of Illinois Urbana-Champaign. There isn't much we can't do--we look forward to serving you at Shortbar.
"Shortbar did a tricky install of a switched connection to an existing J-box in the concrete ceiling of my condo. If youâ ve owned a high-rise concrete place before, you know that can be tricky, but Shortbar figured out how to hook my new light fixture up to an existing 3-way switch and patched the holes where they had to open up the wall."

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.
