Best Fire-protection contractors in Bellevue, WA
A ranked shortlist of licensed fire-protection contractors for someone hiring or vetting in Bellevue. Ranked on an active L&I class for the work and job-relevant Bellevue city building records, not reviews, ads, or a workmanship guarantee.
Bellevue city building records through 2026-10-20, verified against the Washington State Department of Labor & Industries licensing records, snapshot dated 2026-08-16. Ranking reflects license standing and city building records, not a workmanship guarantee. This week's Bellevue city building records.
Which fire-protection contractor has done the most fire-protection jobs in Bellevue?
Cascadia Fire Protection LLC has done the most fire-protection jobs in Bellevue of any firm holding the matching L&I class: 539 jobs, most recently in 2026. It has held L&I license CASCAFP833L2 for 9 years.
That count includes only city building records whose type matches fire-protection work in Bellevue's own records, and only firms that hold the matching L&I class as a primary or tied specialty, so a firm with a larger pile of unrelated jobs does not rank here. Jobs are counted per license number, and a firm holding several licenses is counted on its busiest one. Bellevue records run through 2026-10-20.

How this ranking works
Organic results require an active L&I license, the correct class for the trade as the firm's primary or tied fit (a mechanical company that also holds an electrical license does not lead the electrician list), and at least one job-relevant city building record in this city. They are ranked by the number of relevant jobs, then by how recently the firm worked, then by how long the firm has been licensed. This reflects license standing and real city building records - it is not a workmanship guarantee. L&I does not publish a disciplinary file, so a clean record is not part of this ranking. Promoted entries, when present, are paid placements and are not scored by these rules.
Confidence: high. The job type and the license class both match this trade.
Frequently asked questions
- Which fire-protection contractor has done the most fire-protection jobs in Bellevue?
- Cascadia Fire Protection LLC has done the most fire-protection jobs in Bellevue of any firm holding the matching L&I class: 539 jobs, most recently in 2026. It has held L&I license CASCAFP833L2 for 9 years. That count includes only city building records whose type matches fire-protection work in Bellevue's own records, and only firms that hold the matching L&I class as a primary or tied specialty, so a firm with a larger pile of unrelated jobs does not rank here. Jobs are counted per license number, and a firm holding several licenses is counted on its busiest one. Bellevue records run through 2026-10-20.
- How are the best fire-protection contractors in Bellevue ranked?
- Organic results require an active L&I license, the correct class for the trade as the firm's primary or tied fit (a mechanical company that also holds an electrical license does not lead the electrician list), and at least one job-relevant city building record in this city. They are ranked by the number of relevant jobs, then by how recently the firm worked, then by how long the firm has been licensed. This reflects license standing and real city building records - it is not a workmanship guarantee. L&I does not publish a disciplinary file, so a clean record is not part of this ranking. Promoted entries, when present, are paid placements and are not scored by these rules.
- Is this ranking a guarantee of quality or workmanship?
- No. It reflects Washington State Department of Labor & Industries license standing, longevity, and real city building records - not the quality of any individual job. Always verify a contractor on the official L&I Verify a Contractor and check references before hiring.
- How current is this Bellevue contractor data?
- Bellevue city building records through 2026-10-20, verified against the Washington State Department of Labor & Industries licensing records, snapshot dated 2026-08-16. The two datasets age separately: the board publishes licensing snapshots on its own cadence, and Bellevue publishes city building records on its own. This page regenerates daily.
