"It was very easy to work with Joe to finalize a quote and get the job scheduled. Once onsite, Carlos and his colleague knew exactly what to do and how to run the new electric circuit across the house from the electrical panel to the garage. The installed the EV charger we had purchased separately exactly how we wanted it. Everything worked perfectly. They even went the extra mile to come back and patch the garage drywall where they had made a few holes to run the cable even though it was not included in the job initially. Overall very happy with both the price we paid and the quality of the work. Will hire again for any electrical work we'll need."

"You cannot find a better contractor than Raufi Services. We hired Raufi Services to install 240V/50A wiring for a hot tub. They were extremely efficient, polite, and timely. The quality of their work was outstanding--I couldn't even tell they ran the wiring in the house after they were done. They were also very competitive in their cost estimate."

"The company technicians, Steven, James and Zack were very professional and competent. They did excellent job in both removing the old unit and installing the new one. In addition to this job, we have used Appleton Campbell for several projects over the past couple of years, to include, installing a back up propane generator, installing replacement electrical lighting, and replacing a hot water heater. The company and their personal, to include both field and office individuals, were very competent and courteous. We highly recommend this company to other individuals."

"I called E-Tec at the referral of another Angie's List contractor I'd already selected to install attic insulation. I spoke with them on Thursday after 5:00 PM, and they had their electrician to my home first thing Monday. Krys was great. He took time to investigate the possibilities for an attic fan and explained my options, which were limited due to the attic configuration. He then installed 3 ceiling fans, which took the better part of the day. He also installed 2 motion sensor lights which weren't on the original work order. One fan was a bit noisy when installed and we discussed whether to replace it. I opted not to. Two weeks later, that fan became really noisy, so Krys came back out to fix the problem. E-TEC charged just the base installation cost for this work, which I feel was fair. The only problem I had was a math error on the original invoice (which I should have caught earlier) but Nicole at E-TEC helped get that corrected within a day of my phone call back to the company."

FAQs for electrical for home addition or remodel installation projects in Markham, VA

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.
