"Bradley knows what heâ  s doing. I originally hired Seatown Electric to come out and install an in-house backup generator. Bradley came out to install the generator and found that we had some pretty dangerous wiring at the panel and it was not nearly up to code. I was in the HVAC industry 30 years ago and the mechanical theory in which Bradley explained made complete sense. Bradley finished up the generator install and he gave me a bid to fix the issue. The same day, we called Seatown and we made an appointment for him to come back and do the work. Bradley and Austin showed up at 7:50am, 10 minutes before the job started. They met with me and got started. I always like to look at service techs trucks to see what kind of person is working on my home. Bradleyâ  s truck was immaculate. Extremely organized, very clean and it looked like a service truck that was on the DeWalt showroom floor. The instant I saw Bradleyâ  s truck, I knew his work was going to be perfect. The professionalism from both Bradley and Austin was outstanding. They worked extremely hard for almost 11 hours that day. They didnâ  t mess around, they had their mind set on the job and I was extremely impressed at their work ethic. We have been through 4 major renovations between our two homes and have used a myriad of different contractors, but never have we had a team close to as good as these guys. I would put every apprentice with Bradley, he knows what he is doing. Seatown is lucky to have this guy, they better take care of him. Great job guys!"

"Team was excellent, as people and craftsmen. Ask for Jeremy when you call to have your electrical work completed. They found an open circuit that was keeping two outlets from working and installed a new box in my kitchen then installed my new garage door opener."

"Nathan installed several outlets in our garage , a new security light behind the garage, and corrected the wiring to our court lights. He did a great job with all the work, routing the wiring very neatly, installed the outlets where I wanted them and advised me on the best way to get what I needed. He was very open to all my questions as well as my grandson’s questions about why Nathan did things a certain way. Nathan was very patient and made sure we both understood the reasons and methods for his work. Excellent work ethic. Highly recommend Nathan for any electrical work you and your friends/family might have."

"I couldn't have hoped for a better experience. The scheduling was professional and prompt, the service was spot on and high quality. They arrive in a nice truck with lots of supplies, and do a quick estimate, then get right into it. I had a list of jobs saved up, which included installing new bathroom fixtures and new outlets. Everything was done just right and the area left clean and everything tested out to my satisfaction. No surprise in the bill and I felt it was a fair price.

FAQs for electrical for home addition or remodel installation projects in Mercer Island, WA

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.
