Contractor insurance documents and dock construction site review

Marine construction work happens in and around water, near electrical service, with heavy equipment, on someone else's lake. The insurance and licensing that protects you when something goes wrong is the difference between a manageable inconvenience and a financial catastrophe.

General liability insurance — table stakes

Every legitimate waterfront contractor carries commercial general liability (CGL) insurance with a minimum $1 million per occurrence and $2 million aggregate limit. The certificate of insurance (COI) should list the homeowner or property owner as an additional insured for the project duration. If a contractor can't or won't produce a current COI within 24 hours of request — walk away. This is the most basic professional-operations bar in the industry.

Read the COI carefully. "Waterfront construction," "marine construction," or "dock construction" should appear as an authorized operation, not just "general construction." Standard general construction policies frequently exclude waterborne or in-water work, and a contractor with a general policy doing dock work is uninsured for the actual job. We carry marine-specific coverage and the COI says so.

Workers' comp — the one that matters most

Workers' compensation insurance covers the contractor's crew if anyone is injured on your property. Without it, a single back injury during dock framing could become your liability if the contractor is structured to pass it through. Texas doesn't require workers' comp at the state level, which makes verification more important here than in most states. Demand a current workers' comp certificate; if the contractor uses subcontractors, demand the same from each sub.

If the contractor responds with "my crew are all 1099 contractors so I don't need workers' comp" — proceed carefully. That structure can be legitimate in some cases, but it shifts injury liability to you (the property owner) if a court finds the 1099 status doesn't hold up. We carry workers' comp on all employees and require it from every subcontractor. The bid comparison article covers how this often shows up as a price difference between bidders.

Licensing requirements (or lack thereof) in Texas

Texas doesn't license marine contractors at the state level — unlike Florida, Louisiana, or some Gulf Coast states. That means there's no "contractor license number" to verify the way you would in those states. The functional equivalents in Texas are: an active LLC or business entity registration with the Secretary of State, current sales tax permit, and (for electrical work on docks) a Master Electrician license held by the contractor or a named subcontractor. Verify all three.

Permitting relationships with the lake authority are the closest thing to industry licensing on East Texas reservoirs. A contractor who has pulled 50+ TRWD permits is functionally credentialed; one who's never submitted to the authority is functionally not. Ask for the authority pull history; a real local contractor will have it documented. See the Cedar Creek questions-to-ask article for the full vetting framework, and the permit-denial article for why a real authority relationship matters when the submission hits friction.

Bonds, warranties, and contract terms

Performance bonds aren't standard on residential waterfront work but should be in place on commercial, HOA (see HOA reserve planning), or any project above $150,000. The bond protects you if the contractor walks off mid-job; the bonding company completes the work. Warranty terms matter — both the manufacturer warranties on installed materials (which transfer to you on completion) and the contractor's own workmanship warranty (typically 1–3 years; we carry 3 on all new builds). Read the warranty document, not the marketing brochure that summarizes it. The demolition-and-replacement article shows how warranty terms should look on a real scope.

Contract terms to verify: clear scope with line items (not lump-sum), payment schedule tied to milestones (not arbitrary dates), change-order process in writing, and a defined dispute-resolution mechanism. Avoid contractors who want full payment upfront or won't put line items in writing — both are warning patterns. Get on our schedule for a quote and you'll see how every line should look.

Vetting a contractor takes 30 minutes of document review and saves the worst-case outcomes of waterfront construction gone wrong. Demand the COIs, verify the workers' comp, check the LLC and authority relationships. We're happy to walk through ours; any legitimate contractor will be the same.
