Our Process

How It Works

  1. 1
    Depth & riparian survey

    We confirm water depth at mean low tide and how far your riparian rights allow you to extend.

  2. 2
    Design & permitting

    We design the extension and secure any required permit amendment or new permit.

  3. 3
    Construction

    We tie the new section structurally into your existing dock for a seamless, code-compliant result.
