Our verification notes
Brand consolidation creates contracting-entity ambiguity: Groundworks says Matvey joined it in 2024, while BBB also treats Rainy Day Basement Systems as a Groundworks alternate name. The captured WA number appeared on a 2023 county permit; verify the exact current L&I entity/registration on the proposal. Concrete lifting is not whole-house flood elevation.
