Under Construction Co. is led by Bill Westphal, a residential contractor with more than 30 years of hands-on experience serving Monterey, Pacific Grove, Carmel, and the surrounding Peninsula. Bill’s approach is simple — do the job right, communicate clearly, and treat every home with care and respect.
Bill takes a hands-on role in every project. Rather than outsourcing design and permitting, he works directly with homeowners to draft plans, manage approvals, and shape the entire vision before construction begins. This approach keeps projects efficient, aligned with your goals, and grounded in practical experience.
Most remodels start with an addition or structural change and naturally expand into updated kitchens, bathrooms, and interior improvements — the kind of comprehensive work Bill is known for. His long-standing subcontractors bring reliability and consistency to each job, ensuring safe, clean job sites and craftsmanship that lasts.
We handle drafting, design guidance, and permitting in-house, giving you a seamless experience from the first sketch to the final walkthrough.
Bill works directly with every homeowner, setting real expectations and keeping you informed at every stage of your remodel.
With long-standing crews and decades of experience on the Peninsula, your project is built with care, consistency, and attention to detail.
Bill’s career in construction began when he was 15, long before most contractors ever step onto a jobsite. Over the decades, he has built a reputation rooted in hard work, honesty, and deep practical knowledge of every phase of residential remodeling. This timeline reflects the milestones that shaped Under Construction Co. into the trusted, Peninsula-focused company it is today.
Bill began working in the trades at age 15, learning foundational skills and gaining hands-on experience long before becoming a licensed contractor.
By 21, Bill was leading crews and managing projects, earning trust through his work ethic, reliability, and problem-solving skills.
After 15 years of field experience, Bill earned his California contractor’s license — already deeply knowledgeable in framing, remodeling, additions, and finish work.
Under Construction Co. completed hundreds of remodels and additions across Monterey, Pacific Grove, and Carmel, developing long-term relationships and a trusted local reputation.
Bill continues to lead every project personally — drafting plans, managing permits, guiding design, and ensuring craftsmanship that stands the test of time.
Most of our work comes from referrals — a reflection of the trust homeowners place in our workmanship and our team.
At Under Construction Co., we provide homeowners with a straightforward, full-service remodeling experience. Bill works directly with you from the first design conversation to the final inspection, handling drafting, permits, and project coordination so your remodel feels organized, efficient, and clearly guided from start to finish.
