De Barra Plumbing

De Barra Plumbing is a family-owned, San Francisco-based company led by Dermot Barr, bringing over 30 years of trade experience to the Bay Area. We combine traditional Irish craftsmanship with modern building science, having recently pivoted our business model to lead the residential electrification movement. ​We distinguish ourselves by blending 'Old World' reliability with cutting-edge 2026 compliance. Our team—including seasoned hydronic specialists and a dedicated father-son service crew—is specifically trained to handle the unique challenges of San Francisco's housing stock (tight Sunset District utility closets, complex hydronic retrofits, and aging electrical panels). We offer a 'One-Stop Shop' experience, managing the entire incentive stack to make fuel-switching seamless and affordable for our neighbors.
