Bay Stone Builders is a licensed California general contractor (LIC# 1118494) built to handle a remodeling project start to finish — from the first walkthrough to the final walkthrough — across Santa Clara and San Mateo Counties. Here's the full scope of what we do, how we run a project, and where you can see the proof.
The 5 Things We Build
Kitchen Remodel
High-quality kitchen remodels — updating outdated appliances and redesigning your layout so your kitchen actually works for how you live. We handle everything from cabinetry and counters to full layout reconfiguration.
Bathroom Remodel
From full-scale renovation to simple updates, we manage every bathroom remodel with the same attention to detail — tile, fixtures, plumbing, and layout.
Interior Design
Space transformation that balances function and beauty. Our interior design work supports every remodel we build, from material selection to final finishes.
ADU Construction
Accessory Dwelling Units (ADUs) built for California homeowners looking to add living space, rental income, or room for family — part of our whole-home and addition capabilities.
Home Additions
Seamless home additions that expand your living space without feeling like an add-on — matched materials, matched craftsmanship, one cohesive home.
How We Work
1. Consultation
We walk the property, listen to your goals and budget, and talk through what's realistic for the space.
2. Detailed Plan
You get a clear scope of work, timeline, and pricing before any construction starts — no surprises mid-project.
3. Design & Permits
We finalize materials and layout and handle the permitting requirements that apply to your specific project and city.
4. Construction
Clean, safe job sites and steady communication the whole way through — you always know what's happening and what's next.
5. Final Walkthrough
We walk the finished space with you and don't consider a project done until you do.
