The difference between a mediocre paint job and a museum-grade finish is almost entirely in the preparation. Our master painters execute multi-step surface preparation protocols — filling, sanding, priming, and sealing — before a single topcoat is applied. The result is a finish that holds for decades rather than years, and looks better at five years than most painters' work looks on day one.
We apply the same material specification discipline to painting that we apply to structural work. Every project begins with a materials review — evaluating the existing substrate, moisture conditions, sun exposure, and finish sheen requirements — before we recommend a paint system. In Marin's coastal climate, vapor permeability and UV resistance are as important as color accuracy.
ConstruBay (CSLB #1106798) is based in Mill Valley and has executed interior and exterior painting projects across Marin, Sonoma, and Napa Counties.
What Is Included
The Marin Advantage
Exterior painting in Marin County's coastal climate requires paint systems formulated for salt air, high UV exposure, and significant moisture cycling between wet winters and dry summers. We specify exterior paint systems with elastomeric properties for wood substrates that experience seasonal movement, and we use vapor-permeable primers on any substrate where moisture intrusion is a risk. For historic properties in Mill Valley and Ross that are subject to Design Review Board approval, we manage color approval submissions as part of the project scope, coordinating with the relevant preservation guidelines.
