New Construction, Maintenance, & Accessories

  • With over 35 years of experience on Possum Kingdom Lake and the surrounding areas, we understand the unique challenges of local salt content and corrosive conditions.
    We pride ourselves on building dock bases that are engineered to withstand the elements and stand the test of time.

    Our dock bases are fabricated with heavy-duty I-beams and finished with a durable metal roof.
    Every material we choose is selected for long-term safety, strength, and stability—so your dock stays solid and secure.

    We offer both galvanized and painted bases.
    Whichever option you choose, you can feel confident knowing your dock has the dependable support it needs.

    We also offer composite decking in a variety of colors, including (but not limited to) Rocky Harbor, Toasted Sand, Foggy Wharf, and several other beautiful options to match your style.

    Our custom boat docks give your home a true luxury lake-life look—built tough, built right, and built to enjoy for years to come.
