We're the oldest and most experienced residential and commercial marine construction company in Greater Seattle. We’ve been making friends in the Puget Sound region since 1947, and our craftsmanship and customer service are second to none.

Our pricing is fixed and firm  We’re one of the few Lake Washington contractors that takes the time to analyze and understand the entire job, allowing us to eliminate unknowns and risks. We budget for the unexpected to make everything expected. We’re then able to offer a fixed and firm price without hidden costs or change orders on any part of the project without your consent. We also include permit costs in our original bid, unlike most contractors who will add these later.

We take pride in all our projects  Our employees have been constructing docks and bulkheads with us for a long time – each an average of 19 years, longer than most of our competitors have been in business. And we don’t compromise on the quality of the product or service.

The majority of our business is either referral or repeat customers  As a new customer, we’d be honored to have you contact existing customers for a reference. Just ask us for contact information.

How We Work

The scope of work determines the cost of the project  For some of our projects, the scope of work includes:

  • Epoxy coated steel piles to ensure against rust. Steel can provide a solid foundation for more than 100 years.
  • Dock structures feature galvanized steel beams and treated wood stringers for a no maintenance, 50+ year life.
  • Docks are built with attractive and functional engineered beams made of custom milled 300 year-old Alaskan Yellow cedar.

We stand behind our work with a limited 3-year warranty, which covers the structure and materials and confirms we deliver the highest quality product on Lake Washington.

We aren’t satisfied until you are  We’re so confident that you’ll be thrilled with your final project that we won’t require 80% of the project cost until you’ve agreed that we’ve exceeded your expectations.

Whether you're looking to repair your dock, build a new one, or even just need dock or boat accessories, we're here to help. Please give us a call with any questions you may have about your next project:
