Company History & Growth

The company was officially launched in early 2016 by owner Brandon Guillen. He started the business after noticing a widespread lack of quality craftsmanship in the local market. By personally selecting the best foremen he knew—each with over 20 years of experience on average—he built a foundation of skill and reliability. A focus on great design-build models and positive customer experiences has driven their steady growth in Oakland, CA and beyond.

Leadership with Hands-On Experience

Brandon Guillen leads American Grade Construction with six years of experience running a successful construction company. His direct involvement and commitment to hiring only the top 10% of tradespeople in the Bay Area set the standard. The foremen are not just managers; they are master craftsmen who work on-site, ensuring every detail meets their high standards.

Specialties & Highlights

What makes American Grade Construction different? Here are a few key points:

  • 5-Year Warranty: They are licensed, bonded, insured, and use top-quality German-engineered materials. This allows them to offer extended manufacturer warranties on critical items like shower systems.
  • Quality Craftsmanship Mission: They actively hire, train, and retain the most skilled craftsmen and craftswomen in the region.
  • Same-Day Estimates: Their in-house estimating platform lets them provide a fair, detailed quote on the day they visit your home.
