Marine & Waterfront Construction Services in Seabrook, Kemah, League City, and all of the Texas Gulf Coast

Custom Coastal Construction is a leading provider of marine and waterfront construction services in Seabrook, Kemah, League City, and all of the Texas Gulf Coast. With the region’s close proximity to Galveston Bay, Clear Lake, and the Gulf of Mexico, reliable and resilient waterfront structures are essential. Our company builds and maintains coastal installations designed to withstand the unique environmental challenges of Texas shorelines.

Comprehensive Dock and Pier Construction


Docks and piers are among the most frequently requested marine construction projects in Seabrook, Kemah, League City, and all of the Texas Gulf Coast. Our team handles both residential and commercial dock builds, including fixed and floating options. Every structure is tailored to accommodate water depth, tidal fluctuations, boat accessibility, and local building codes. We also build custom fishing piers for private properties along the coast. These are reinforced with marine-grade lumber and stainless hardware to combat saltwater exposure and humidity over time.

Bulkhead Installation and Shoreline Retention

Bulkhead construction is a core marine service that protects properties from erosion and tidal impacts. In Seabrook, Kemah, League City, and all of the Texas Gulf Coast, bulkheads are critical due to recurring storm surges and soil shifting along the waterline. Custom Coastal Construction installs wood, vinyl, and steel bulkheads reinforced with tieback systems and proper drainage channels. Each project is engineered based on soil conditions, wave exposure, and the type of waterfront development. We also offer repair services for aging or storm-damaged bulkheads that need structural reinforcement or realignment.

Custom Boat Houses and Boat Slips

In coastal neighborhoods throughout Seabrook, Kemah, League City, and all of the Texas Gulf Coast, boat houses and boat slips are essential components of waterfront living. We design and construct custom boat houses that incorporate lifts, decks, and roofing systems to protect watercraft from sun and rain exposure. Boat slips are constructed with reinforced pilings and accessible mooring points for a wide range of vessel sizes. Whether integrating into a residential dock or building a stand-alone structure, we ensure each installation adheres to state regulations and practical functionality for daily marine use.

Marine Piling Installation and Wrapping

Piling installation serves as the structural foundation for most marine projects, including docks, piers, and boat slips. We handle both driven timber piles and auger-cast pilings, depending on the substrate and load requirements. In Seabrook, Kemah, League City, and all of the Texas Gulf Coast’s brackish water conditions, pilings are exposed to decay, marine borers, and constant wave action. That’s why we offer piling wrapping services using high-grade PVC sleeves and epoxy coatings. These wraps extend the service life of pilings, reduce maintenance costs, and enhance the overall stability of any waterfront structure.

Fishing Piers for Residential or Recreational Use


Fishing piers are a distinct specialty in our waterfront services portfolio. We build private piers along canals, bays, and lakes that are customized with railings, benches, lighting, and cleaning stations. The structures are designed for safe load-bearing capacity and long-term durability, even in high-moisture environments. Seabrook, Kemah, League City, and all of the Texas Gulf Coast residents who want to integrate recreational access into their property benefit from piers that are both functional and architecturally integrated with the shoreline aesthetic.

  • Seawall and Retaining Wall Construction for Coastal Stability

    Retaining walls serve a dual function in many marine construction projects by preventing land erosion and supporting grade transitions on waterfront properties. In locations where vertical elevation changes meet waterlines—especially along the slopes near Clear Lake—these walls are essential to long-term soil stability. Our seawall systems incorporate interlocking blocks, concrete reinforcement, and engineered drainage solutions to minimize hydrostatic pressure and shoreline displacement over time.

  • Dredging and Waterway Access Services

    To maintain navigability and usable water depths around docks and boat slips, we provide targeted dredging services. These involve the strategic removal of silt, sediment, and debris that naturally accumulate in canals and shallow inlets around Seabrook. Our team evaluates the environmental impact, secures the necessary permits, and uses low-impact equipment to dredge around residential or commercial marine structures. This improves access for larger vessels, enhances safety, and supports flood mitigation efforts during storm season.

  • Structural Repairs and Marine Renovations

    In addition to new construction, Custom Coastal Construction performs structural repairs and marine renovations across Seabrook. From dock resurfacing to boathouse frame stabilization, our services are tailored to protect your investment and restore full usability. We also conduct piling realignment, deck replacement, and lift mechanism upgrades. All materials used are marine-rated to ensure compatibility with the surrounding saltwater environment.

  • Permitting and Coastal Compliance

    Working on waterfront properties in Seabrook, TX requires a thorough understanding of local, state, and federal permitting regulations. Our team navigates the permitting process on behalf of our clients, ensuring compliance with the Texas General Land Office (GLO), U.S. Army Corps of Engineers, and city-level requirements. This includes shoreline development, dredge-and-fill permits, and floodplain adherence. We ensure that all marine construction projects proceed without costly delays or legal issues.

Coastal Expertise for Every Marine Project


The geography and climate of Seabrook, Kemah, League City, and all of the Texas Gulf Coast demand specialized expertise in marine construction. Tidal fluctuations, saltwater corrosion, and storm surge exposure are all challenges that influence how docks, boathouses, and bulkheads are built and maintained. Custom Coastal Construction combines practical marine building knowledge with regional experience, delivering durable waterfront structures that endure.
