Design-build kitchens, bathrooms, additions, ADUs, whole-home remodels & outdoor living — one dedicated team from design through construction.
New Bay Builders serves San Mateo homeowners with full-service design-build remodeling. We’re currently remodeling in San Mateo, bringing our one-team design-build approach — from first sketch to final walkthrough — to kitchens, bathrooms, additions, ADUs, whole-home remodels, and landscaping & hardscape across the city.
Every project starts with a free consultation and a detailed written scope, so you know exactly what’s included before work begins.
