Our Composite Dock Solutions

At Alki Deck Builders, we provide comprehensive outdoor solutions tailored to your lifestyle, property, and budget. Our full-service approach covers design, material selection, permit acquisition, and expert installation to transform your outdoor space.

Dock Installation

Every composite dock installation we complete is guided by a thorough understanding of the site, the water conditions, and the client's intended use. We manage permitting, framing, and construction as a complete package so nothing is left to chance.

Dock Repair

Structural repairs and piling repairs on existing residential docks are handled with the same precision we bring to new builds. We identify the root cause of every issue and complete repairs that restore full structural performance rather than masking surface symptoms.

Dock Framing

Wood framing systems form the structural core of every residential dock we build, providing the load-bearing backbone that the composite surface above depends on. Every framing decision is made with long-term stability and material compatibility in mind.

Custom Dock Design

Our team designs and builds stationary docks, suspended docks, piling docks, and fully custom residential dock configurations. Every layout is developed specifically around the shoreline characteristics, water depth, and intended use of the property it serves.

Benefits of Professionally Installed Composite Docks

Minimal Upkeep, Maximum Enjoyment

Composite residential docks resist rot, splintering, and moisture damage, meaning less time maintaining and more time using your waterfront.

Waterfront Investment That Pays Off

A professionally built residential dock adds lasting property value and expands the functional appeal of any waterfront property.

Structurally Sound and Legally Compliant

Every residential dock we build meets local regulatory requirements. Permit acquisition and code compliance are handled on your behalf from day one.

Precision-Fit for Your Shoreline

Dock type, layout, and material selection are all developed around the specific conditions of your property rather than applied as a one-size solution.

Performance Through Every Season

Composite materials combined with expert construction deliver residential docks that hold up through years of waterfront exposure with no compromise in appearance or stability.
