Nine Mile Builders was established in 2017 by Tim Cox, a Peaks Island native and longtime Portland resident. Tim brings extensive expertise gained from working with several high-end contractors and custom cabinet makers throughout the region before launching his own business. Over the years, Tim has strategically evolved the company’s focus toward energy-efficient construction and bespoke millwork, reflecting a commitment to sustainability and craftsmanship.

Today, Nine Mile Builders remains a family-operated business, with Tim and his wife Olivia at the helm. Olivia expertly manages the essential behind-the-scenes operations, ensuring seamless business workflows, while Tim divides his time between office management and hands-on work in the field.

We collaborate extensively with trusted local subcontractors who have consistently demonstrated a strong commitment to quality and reliability. By partnering with professionals deeply familiar with the local building codes, community standards, and supply networks, we ensure each project is executed smoothly and efficiently. This close working relationship allows us to maintain clear communication, uphold rigorous quality control, and deliver superior craftsmanship that meets our clients’ expectations. Our network of subcontractors is carefully vetted, ensuring they share our values of integrity, professionalism, and attention to detail, which ultimately results in a finished product that stands the test of time.

We also partner closely with local architects to deliver tailored plans and innovative designs for homes, additions, and renovations. Whether you need design development from concept to completion or already have blueprints and are seeking the right builder, we welcome the opportunity to connect. We are committed to transparent communication and collaborative project management to ensure we are the ideal fit for your vision and goals.
