DDNWCC LLC is a small, local general contracting and home repair business based in Bothell, Washington, owned and operated by the uncle‑nephew team of David Hills and Dylan Koidahl. We built this company around a simple mission: From full renovations to everyday repairs, we support your home at every stage.
Whether you need a full remodel, a new deck, or just a reliable handyman for the small things, we’re here to help. As a veteran‑owned business, we bring a service‑driven mindset, clear communication, and a commitment to doing things the right way — not the fast way.
Dylan brings a strong technical foundation and a wide range of field experience to the company. He holds a degree in Construction Management, and his career has taken him through key roles across the industry — including Project Superintendent, Project Engineer, Master Carpenter, and Restoration Technician.
This combination of management expertise and hands‑on skill allows Dylan to bridge the gap between planning and execution. He understands how to coordinate a project from the ground up while ensuring the craftsmanship meets the highest standards. His calm professionalism and deep industry knowledge make him a trusted partner for homeowners throughout Bothell and the surrounding communities.
David brings a veteran’s discipline and more than two decades of technical, problem‑solving experience to DDNWCC. Before entering the construction industry, he spent over 20 years in roles that required precision, planning, and the ability to break down complex challenges into clear, actionable steps. That background now shapes the way he approaches every project: methodically, thoughtfully, and with a focus on long‑term durability.
Homeowners appreciate David’s reliability, communication, and steady approach — whether he’s troubleshooting a tricky repair, coordinating a remodel, or handling the small fixes that keep a home running smoothly. His blend of hands‑on craftsmanship and systems‑driven thinking helps ensure every job is completed with care and professionalism.
Choosing a contractor — or even a handyman — is about trust. We prioritize transparency, communication, and a “done right the first time” mentality. From small repairs to full renovations, we treat your home with the same respect and care we give our own.
We’re proud to be a local, family‑run business serving Bothell, Snohomish County, and North King County with dependable general contracting, home improvement, and handyman services.
