A TO Z INSULATION SERVICES scores 644 — these providers rank higher on Verdica's composite trust score.
The Verdica score is a composite trust score from 300 to 850, computed from workplace safety inspections and 50-state contractor licensing maintained by OSHA and state licensing boards. A score of 644 places A TO Z INSULATION SERVICES in WA in the elevated-risk (580–669) band. The score reflects publicly available regulator data — it is not a rating from Verdica itself and does not incorporate paid reviews or advertising.
Verdica combines three weighted sub-scores drawn from OSHA and state licensing boards. Each sub-score reflects a different dimension of construction compliance — OSHA inspection outcomes, citations, and license status across states — and is normalized against industry peers before being aggregated to the 300–850 scale.
Verdica pulls public records from OSHA and state licensing boards: workplace safety inspections and 50-state contractor licensing. Data is refreshed on rolling cycles, typically weekly to monthly depending on the source agency's own update schedule.
