Read from L&I Contractor License Data - General, published by the Washington State Department of Labor & Industries; our copy is from 2026-10-31. The name, address and phone are those the company filed with the regulator, reproduced as published. A permit shows the licence was on file the day it was filed. These rows show what the regulator holds now. The record is matched to B&T Service by company name, and only where that name resolves to exactly one licence in the register — a rule measured at 99.4% correct against permits whose licence number we already know. Verify with the authority before acting on it.

Public Seattle permit records through 2026, counted by distinct permit number. This is a historical filing record: it cannot show current backlog, pricing, crew availability, licensing or insurance, and a quiet period may only mean work was filed elsewhere.
