"I can't say enough about the team at Cotti-Johnson. From my scheduling with Mel, to the estimate with Ryan and finally, the install crew of Gil, Luis and Nick. Everyone was so professional, courteous and time-considerate. Gil even took extra time to mop my floor to ensure that they left no trace of working in my home! I would recommend this team in a heartbeat."

"We hired V. ISA GENERAL CONSTRUCTION CONTRACTING to remove / deactivate knob and tube wiring and update all our home’s wiring. The service was extremely professional, and far exceeded our expectations. We had a thorough walkthrough both before and after the work was completed, and the company was able to work with us as we made changes during the engagement. Because we had such a good experience with our electrical project we plan to hire them again for additional projects at our home. I could not have asked for an easier group to work with and they made me feel extremely comfortable throughout the entire experience."

"Little Dave came out today and diagnosed and replaced my exterior electrical wiring. If it had not been replaced could have been very dangerous for me in the future. Just knowing that he could fix the problem made me feel safer in my home meant the world to me. He had been out to my house before and fixed some wiring issues in the past also. Dave and his associates have been very professional and courteous. I will call them again if ever I need an electrician. I recommend their services highly. A+"

"David did an amazing job. He called me very quickly after I signed up on Angi. He set up a time to do the job within 4 days. He got both jobs done in a very short amount of time. His price was really reasonable. I would not hesitate to hire David again!"

"I needed to have the electric switch/light dimmer replaced for my Dining Room light. I felt that I was grossly overcharged for their services based on the time that it took to replace the switch. I was charged a total of $257.00; which included $50.00 for the new switch and $200.00 for the labor and diagnosis. The $200.00 labor portion was exorbitant because it took the electrician only 15 minutes to replace the switch. Additionally, the electrician arrived at my home 2 hours later than the time that the appointment was scheduled for."

"When I needed the service, it was on a weekend. I called him, he dropped what he was doing with his family to help me with my house. That was huge for me because I had no electricity. He went above and beyond. The plus was my wife had just had a baby a week before that happened."

FAQs for electrical for home addition or remodel installation projects in Johnston, RI

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.
