Marine Construction FAQ Lake Conroe & Lake Livingston

In most cases, yes. Projects on navigable waterways require a permit from the U.S. Army Corps of Engineers, and private lake communities often have their own HOA or lake authority approval process. G&C handles the permitting paperwork for you as part of every project — we know the requirements for Lake Conroe, Lake Livingston, and Greater Houston waterways.

We handle all permitting paperwork as part of every project — including U.S. Army Corps of Engineers permits where required, SJRA on Lake Conroe, and Trinity River Authority on Lake Livingston. You don’t navigate the agencies yourself. We prepare the applications, track approvals, and keep you informed throughout.

Standard Lake Conroe permits are typically processed by the SJRA within 2–5 business days — significantly faster than the industry norm, due in part to the working relationship we’ve built with the agency over the years. Note that the SJRA requires HOA approval as a prerequisite, and HOA timelines vary by community. Combined, plan for approximately 10 days total for all Lake Conroe approvals. Lake Livingston (TRA) typically runs 2–3 weeks. Gulf Coast projects require 3–6 months. We’ll give you a realistic timeline at the estimate stage.

Yes. Many Lake Conroe communities have HOA design standards for waterfront structures, and we are familiar with the common requirements across the neighborhoods we serve. We review HOA guidelines as part of the planning process and design to comply. If your HOA requires plan approval, we’ll prepare the necessary documentation.

Yes. Ranch ponds, subdivision retention lakes, and private water features are a regular part of our work. Private ponds typically require no state permitting, which speeds the project timeline considerably. Exceptions include ponds that drain into regulated waterways or involve wetlands — we confirm requirements for your specific property before any work begins.

Composite decking (such as Trex or MoistureShield) outperforms wood in Texas’s heat and UV exposure — it won’t splinter, warp, or need annual staining. We also offer wood decking with UV-resistant finishes for customers who prefer the natural look, though composite will still outperform it long-term. Aluminum framing resists corrosion better than treated wood in high-humidity conditions. We’ll walk you through the trade-offs based on your lake, budget, and how you use the dock.

Lifespan depends on the material:

• Treated Wood (20–30 years): Most popular for residential lake properties — proven and cost-effective for calmer, lower-traffic waterways.
• Vinyl Sheet Piling (25–35 years): Maintenance-free, excellent corrosion resistance, naturally resistant to rot and insects.
• Steel Sheet Piling (30–50 years): Built for high boat traffic, strong wakes, and open-water conditions.
• FRP Composite (50+ years): Our premium option by Creative Pultrusions — steel-grade strength with full corrosion resistance; won’t rot, rust, or absorb water.

We’ll help you choose the right material for your site conditions, budget, and long-term goals.

Both hold back soil, but a bulkhead is specifically designed for waterfront use — it must resist hydrostatic pressure, wave action, and boat wake in addition to soil load. Unlike standard retaining walls, bulkheads rely on tie-back systems anchored into the ground behind the wall to handle these additional forces. G&C builds both, each engineered for its specific environment.

We install overhead (vertical) lifts and cable-driven lifts for single and multi-slip configurations. PWC and jet ski lifts are also available. Every lift is custom-specified to your boat and dock — we source components from multiple distributors to build the right lift for each application, rather than locking you into a single brand.

Yes. We install dock lighting and electrical as part of new dock and boathouse builds. We offer our own signature premium light post design, or can customize to match your vision. All waterfront electrical work is coordinated with licensed electricians to meet code requirements for safety around water.

Yes — combination projects are common for us. Many customers replace or build a bulkhead, dock, and boathouse all at once. We manage the entire scope under one contract, one timeline, and one point of contact, which simplifies coordination and typically results in a better overall finished product.

Yes. We evaluate structures regardless of who built them. If a repair is feasible and safe, we’ll take it on. If a structure is beyond repair, we’ll be straightforward about that and walk you through your replacement options.

Yes. We are familiar with the permitting and construction requirements in coastal areas — from the greater Houston area down to Matagorda Bay. Coastal permitting is more rigorous than freshwater lakes, involving both the Texas General Land Office and the U.S. Army Corps of Engineers due to environmental and right-of-way considerations. We’ll walk you through what to expect for your specific location.

Our primary service area is Lake Conroe, Lake Livingston, and Greater Houston — including Harris, Fort Bend, Galveston, and Brazoria counties. Most of our work is within 80 miles of our Plantersville base. We also travel for larger projects — call us with your location and we’ll let you know if we can help.

Every waterfront is different, so pricing depends on footage, water depth, material choices, and site access. A basic residential dock starts around $25,000–$30,000; covered boathouses, large bulkhead runs, and elaborate builds can exceed $100,000. The best next step is a free site visit — we’ll give you a firm written quote at no cost or obligation.

We do not currently offer in-house financing. Many customers fund waterfront projects through a home equity line of credit (HELOC). We’re happy to discuss your timeline and can structure project scope to fit your budget.

A straightforward dock or bulkhead typically takes 3–7 days of on-site work once permits are in hand. Larger covered boathouses or multi-phase projects run 2–4 weeks.

Permitting timelines depend on the governing authority. On Lake Conroe, the SJRA often approves permits within 2–5 days — and because we have an established relationship with an SJRA agent, our applications move faster than most. Note that SJRA requires HOA approval as a prerequisite; some HOAs are very fast, others slower. Combined, the average Lake Conroe permit process takes about 10 days. Lake Livingston (TRA) typically runs 2–3 weeks. Gulf Coast projects require 3–6 months. We’ll give you a realistic timeline at the estimate stage based on your specific location.

During busy season, lead time is typically 6–8 weeks. We run three active crews and work hard to start sooner when scheduling allows. During the off-season, lead time often drops to around 4 weeks. We’ll give you a specific start window when we finalize your contract.

All structural marine construction is performed by G&C’s own crew, under the direct supervision of Victor or Carlos Torres. We may coordinate with licensed electricians for specific scope items, but we do not subcontract the core construction work. When you hire G&C, our crew and our owners are on your job site.

Marine construction is weather-dependent, and we plan for it. If conditions require us to pause, we’ll notify you promptly and return to the job site as soon as it is safe to do so. Weather delays do not affect the final contracted price.

The easiest way is to request a free estimate on our Contact page. We’ll schedule a site visit, walk the property with you, and create a free 3D design so you can visualize your project before committing to anything. Then we follow up with a written quote. No pressure, no obligation.

Yes. New builds come with a 2-year workmanship warranty. Repairs are covered for 1 year. Materials we install also carry their own manufacturer warranties. All terms are spelled out in every written contract. We stand behind our work — if something isn’t right, we make it right.

Our workmanship warranty covers defects in installation, structural failures, fastener issues, and fit-and-finish problems resulting from how the structure was built. It does not cover storm or flood damage, vessel impact, or modifications made by third parties after project completion. Full terms are included in every written contract.

Vinyl and steel bulkheads require very little routine maintenance. We recommend periodic visual inspections for shifting, settling, or hardware issues — especially after major storms. Wood bulkheads benefit from occasional inspection for rot or fastener corrosion at the waterline. We walk every customer through what to watch for at the final project walkthrough.
