Confirm they regularly perform this exact kind of work
Ask about the actual project lane—dock repair, new dock, boat lift, bulkhead, living shoreline, pile work, marine electrical, or another specialty—not just whether they do “marine construction.”

Waterfront Contractor Vetting Checklist
Use the same questions whether a pro came from Shoreline, a neighbor, your Realtor, or somewhere else. Fit, evidence, scope clarity, and execution matter more than a generic star rating.
16 practical checksLicensing varies by scopePrint or share with a homeowner
Use it this way: Use this after you know the kind of pro you need. It is designed to expose mismatches and unanswered questions before a proposal becomes a project.

Make sure this is the right kind of contractor
A strong contractor can still be a poor fit for a particular waterfront project. Start with service, geography, project type, and permitting experience.
Confirm they work in this jurisdiction and waterway area
Local permitting and site conditions matter. Ask whether they routinely work in the property's city/town/county and on similar creeks, rivers, or marsh-front sites.
Confirm the job fits their normal project size and scope
Ask whether the contractor wants this type and size of job now. Fit matters more than forcing a contractor into a project they usually avoid.
Ask who handles coastal, federal, and local permitting
Some contractors manage permit coordination; others expect an owner, surveyor, engineer, or permit agent to do it. Make that responsibility explicit before signing.
Verify
Check public credentials and evidence
Licensing requirements vary by scope. Verify what is actually required for the proposed work rather than assuming every marine project uses the same license.
Verify any state license or registration required for the scope
Use South Carolina LLR and the local jurisdiction to verify the license classification required for the work and the contractor's current status.
SC Contractor’s Licensing Board ↗Confirm applicable local business-license and permit requirements
For City of Charleston work, the City notes that contractor license requirements vary with project scope and that local business licensing can also apply.
City of Charleston Permit Center ↗Look for relevant project or permit evidence
Past permit associations, public portfolio work, and similar completed projects can show activity, but none alone proves quality. Use them as evidence to ask better questions.
Ask for recent, relevant project references when the job is large
A seawall reference is more useful for a seawall than a generic remodeling reference. Ask about communication, change orders, schedule, cleanup, and permit coordination.
Scope & money
Make the agreement hard to misunderstand
Most project friction is easier to prevent before work starts than after a change appears in the field.
Get a written scope that says what is and is not included
The proposal should distinguish demolition, materials, dimensions, electrical, engineering, permitting, disposal, access, restoration, and exclusions where they matter.
Identify allowances, unknowns, and site assumptions
Ask which prices depend on hidden conditions, material choices, engineering, access, subsurface conditions, or agency requirements.
Agree on how change orders will be approved
Changes should be documented before extra work proceeds when practical. Ask who can authorize a change and how cost/schedule impact will be shown.
Understand the payment schedule and milestone logic
Tie payments to a written agreement and clear project milestones. Avoid relying on verbal promises about what a deposit or progress payment covers.
Execution
Know who will actually manage the job
The company you hire and the people who show up can be different layers of the same project.
Know the day-to-day contact
Get the name and preferred communication method for the person who will answer questions once work begins.
Ask what work will be subcontracted
For engineering, surveying, pile work, electrical, or specialty tasks, understand who is responsible for bringing in the qualified trade and coordinating inspections.
Ask for the current lead-time and major schedule dependencies
Permits, weather, tides, materials, engineering, inspections, and access can all affect waterfront schedules. Ask which dependencies are already known.
Define what you receive at closeout
For larger projects, ask for final permits/approvals, warranties, product information, inspection records, and any maintenance instructions that should stay with the property.
When the checklist surfaces a real project
Want Shoreline to help narrow the field?
Describe the project once. Shoreline can structure the details and apply service, geography, project-type, and contractor-fit rules without forcing you into a multi-quote funnel.
