Frequently asked questions
What is low voltage wiring and what does it include?
Low voltage wiring refers to electrical systems that operate at 50 volts or less, as opposed to standard household current at 120 or 240 volts. Common low voltage systems in Seattle homes and businesses include data and network cabling, home theater and audio-video wiring, security cameras, access control systems, smart home wiring, structured wiring panels, doorbell and intercom systems, and smart thermostat wiring. While low voltage systems carry less current, professional installation ensures proper function, code compliance, and clean workmanship.
Do I need a licensed electrician for low voltage work in Seattle?
Washington state requires low voltage work to be performed by a licensed electrician or a separately licensed low voltage contractor. Beacon Plumbing's licensed Seattle electricians handle low voltage installations to code with the same professionalism and one-year guarantee applied to all Beacon electrical work. Unpermitted or unlicensed low voltage work can create issues during home sales and insurance claims.
Can Beacon wire a home theater or smart home system in Seattle?
Yes. Beacon Plumbing's Seattle low voltage team handles home theater wiring, audio-video distribution systems, smart home integration wiring, and network infrastructure for Seattle homes and businesses. We work alongside AV installers and smart home system vendors to pre-wire new construction and remodels or retrofit existing properties. Same-day availability and no trip charges.

What Seattle customers are saying
Thousands of verified reviews from homeowners and businesses across the Puget Sound.
"We moved into a newer home and the WiFi coverage was terrible because there was no wired ethernet infrastructure anywhere in the house. Beacon's low voltage team ran Cat6 to every room, installed a proper structured wiring panel in the utility closet, and terminated everything cleanly. Every device is now connected by wire and the network performance is completely different. Excellent work."
Andrew K. | Eastlake, Seattle | Whole-home ethernet and structured wiring
"We were finishing our basement and wanted to pre-wire for a home theater before the drywall went up. Beacon coordinated with our contractor on timing, ran HDMI, speaker wire, and ethernet throughout the media room, and installed a proper AV rack location in a nearby closet. Everything was labeled, clean, and ready for the AV installer when they arrived."
Sarah T. | Queen Anne, Seattle | Home theater wiring and AV pre-wire
"We had Beacon wire our new townhome for smart home integration including doorbell, thermostat, security cameras at four exterior locations, and a network panel near the main entry. The electrician understood the smart home ecosystem we were using and made sure the wiring decisions were compatible. Clean, professional, and the project finished on schedule."

A message from the owner
Built on hard work and a commitment to this community
Bill Cahill started Beacon Plumbing in 1995 with five trucks and a simple philosophy: hire great people, work hard, and treat every customer the way you would want to be treated. Thirty years later, that philosophy has not changed. What started as a small Seattle operation has grown into a team of 100 licensed, bonded, and insured technicians working around the clock to serve homeowners and businesses across the Puget Sound.
Bill believes deeply in giving back to the community that has supported Beacon's growth. Over the years, Beacon has sponsored the Miss Beacon Plumbing hydroplane at Seattle Seafair, supported Crime Stoppers of Puget Sound in the fight against human trafficking, donated musical instruments and a music teacher to St. George School, and partnered with Northwest Harvest, Ronald McDonald House, and Mamma's Hands. The Seahawks and Mariners logos on Beacon trucks are not just sponsorships - they are a reflection of Bill's pride in Seattle and the people who call it home.
When you call Beacon Plumbing, you are not calling a national franchise. You are calling a company that was built here, employs your neighbors, and is invested in this region for the long haul.
