Why Builders & Contractors Choose Le BROs
New construction electrical demands a contractor who shows up on schedule, communicates clearly with the GC, works cleanly around other trades, and gets inspections passed the first time. That’s what we deliver — consistently, across every project type in the Puget Sound region.
With 20+ years of experience, we’ve worked on everything from spec homes in Thurston to custom waterfront builds in the Puget Sound islands and commercial tenant improvements in Bellevue. We understand the pace of construction and what it takes to keep your project moving.
Washington State Code Compliance
All of our new construction electrical work is performed to the current Washington State adoption of the National Electrical Code (NEC). This includes AFCI protection on bedroom and living area circuits, GFCI protection in kitchens, bathrooms, garages, and exterior locations, tamper-resistant receptacles throughout, and all required smoke and CO detector interconnect wiring.
We stay current on all code amendment cycles adopted by the Washington State Building Code Council, so your project is compliant from the day we start through the day it’s inspected.
