Built on Quality, Detail, and Follow-Through
A local construction company serving Island and Skagit County with a focus on high-quality work and long-term results.
Locally Owned and Operated
One Source Custom Construction was established in 2020 and is based on Whidbey Island. The team handles a wide range of residential construction projects, from remodels to ground-up builds, along with custom structures and exterior work. With a growing team and a hands-on approach, each project is completed with a focus on quality, consistency, and attention to detail.

We Focus on the Details That Matter
What sets One Source apart is a commitment to doing things the right way, not just the fastest way.
Careful attention to detail at every stage
Every part of the project is handled with care, from initial planning to final finishes. Small details are not overlooked, and the goal is always a clean, well-executed result that holds up over time.
Consistent Quality
Each project is completed with the same level of care and craftsmanship, whether it’s a small remodel or a larger build. The focus stays on doing the job right from start to finish.
Clear Communication
Expectations, timelines, and updates are communicated clearly throughout the project. Questions are addressed directly, and nothing is left unclear as the work moves forward.
Reliable Follow-Through
If something needs attention, it gets handled. Even beyond the typical warranty period, work has been revisited to make sure everything continues to perform as it should.
Custom Cabinetry Through Green’s Custom Woodworks
The same attention to detail and commitment to quality extends into custom cabinetry through Green’s Custom Woodworks. Each project is built from raw materials and finished in-house, with a focus on precision, durability, and a clean, well-executed result.

Work That Lasts Beyond Completion
Construction projects don’t always end when the job is finished. If something needs attention, it gets handled. While the standard warranty period is one year, projects have been revisited and supported years later when needed. The goal is to build long-term relationships, not just complete a single project.
Licensed, Bonded, and Insured
One Source Custom Construction is fully licensed, bonded, and insured, and is a member of the Skagit and Island Counties Builders Association (SICBA).
