Our Story:
Hill and Harbor Construction

Hill and Harbor Construction was founded by Seth Olson to focus on low-maintenance, custom decks built to perform for decades. Every part of the company, from the materials selected to the way projects are managed, traces back to a simple standard. A deck should be safe, built right below the surface, and easy to enjoy without constant upkeep.

Experience Across Construction. A Passion for Outdoor Living.

Seth spent his early career in office management before moving into reconstruction, where he managed a restoration company’s reconstruction department. That work gave him hands-on experience with structural repair, estimating, and coordinating complex projects under real deadlines. It also showed him how much of Duluth’s older housing stock struggles with the same underlying problems: Rot, undersized framing, and structures that were never built to last as long as the finish work suggests.

Seth founded Hill and Harbor Construction in 2025 to focus specifically on custom composite and PVC deck construction. Rather than take on a broad menu of general contracting work, he built the company around a narrower promise: Replace unsafe, aging decks with low-maintenance outdoor spaces, built correctly from the framing up. Every project still runs through Seth directly, from the first site visit to the final walkthrough.

A Different Kind of Deck Builder

  • A dedicated deck specialist in a generalist market, focused only on custom composite and PVC decks.

 

  • Direct access to Seth Olson through every decision, not a rotating handoff between office staff and crews.

 

  • Structural-first recommendations, including a willingness to rebuild rather than resurface a compromised frame.

 

  • A maintenance-free material strategy built around TimberTech Advanced PVC and Trex composite decking.

 

  • Material samples and clear education at every site visit, so choices are based on understanding, not pressure.

 

  • Transparent project visibility through JobTread, covering design approval, payments, and daily job updates.

Values That Shape Every Build

  • Build it Right Below the Surface: Framing gets the same attention as the finished decking, with a full rebuild recommended whenever an existing structure is undersized, out of code, or compromised.

 

  • Materials with a Reason: Every product recommendation is tied to performance, not a sales script, so you understand what you’re paying for and why.

 

  • Straight Answers, No Sales Pressure: You receive a design, real material samples, and a detailed estimate, so you can make a decision with full information.

 

  • Respect for Your Home: Your property is treated carefully throughout the project, with daily communication so you always know what’s happening and when.

 

  • Safety is the Starting Point: Most projects begin with a deck that’s rotting, unstable, or no longer safe, and the goal is always a space your family can trust again.
