"Allgood is a great electric company. The gentlemen sent to work on installation and upgrading panels did a terrific job. They were professional, focused, polite, and most informative as they worked. Their pricing was exactly what I thought it should be, which was great. I have a new list of items I want them to work on. Can't wait."

"I contacted ACB Services after waiting behind their truck in a traffic jam. They quickly provided reasonable estimates for multiple projects I was considering. I chose them to do a french door install in an existing interior archway opening. They were easy to work with for scheduling, they responded quickly to my questions, and during the install they were friendly and methodical in their approach. They were careful to clean up dust, etc. as they worked and created an excellent final product. Many thanks to Alan and his crew for the perfect addition to our sunroom!"

"Outstanding communication and very professional service. I would highly recommend Mr. Electric. Received both e-mails and texts on appointment to include a photo and short bio of the actual electrician (Brad Mason) who would be doing the work. Wish all home service providers did the same. Brad was on time (actually a few minutes early). He installed 30AMP breaker and associated RV plug in our garage. To avoid any sheetrock repairs it was necessary for him to drop the line to the house electric panel through a wall with foam insulation, with very limited head/body clearance for him to work. No mess left behind from the actual plug installation on another wall."

"Work was well done, and they thought about how to best install the outlets to serve the needed purpose. Installation was quick and professional, they also cleaned up after themselves. I will use Thundercolt Electric for future electrical needs."

FAQs for electrical for home addition or remodel installation projects in San Antonio, TX

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.
