Market Overview
Jacksonville Waterfront Corridors
Jacksonville marine demand is not citywide demand. Recorded search interest in this market arrives at the level of Mayport, Jacksonville Beach, Atlantic Beach, Ponte Vedra Beach, Riverside and Avondale, and Intracoastal West, not Jacksonville as a whole. Those corridors differ in access, water type, and structure age. A St. Johns River bulkhead in Riverside and a lift on an Intracoastal canal in the Beaches are different jobs bid by different crews, and a contractor strong in one is not automatically strong in the other.
- Mayport and the lower St. Johns Working waterfront, strong current, and older bulkhead structures.
- Intracoastal West Canal frontage and residential lift work. Distinct recorded demand from citywide Jacksonville.
- Jacksonville Beach Separate incorporated city with roughly double the citywide median home value.
- Atlantic Beach Highest median home value in the Jacksonville area, directly against Mayport.
- Ponte Vedra Beach St. Johns County coastal corridor that searches as part of the Jacksonville market.
- Riverside and Avondale Older riverfront dock and seawall stock on the St. Johns.

Provider Profiles

Publishes the most explicit service area statement in this set, naming Jacksonville, Jacksonville Beach, Ponte Vedra Beach, St. Augustine, Amelia Island and Fernandina Beach, and listing Duval, Clay, Putnam, St Johns, Flagler and Nassau counties. Established 1981, which is the longest verified operating history among the contractors reviewed. Requires an onsite inspection before quoting.
Strengths
- Names specific corridors rather than a metro area
- Longest verified operating history in this set
- Coverage spans all four markets compared here
Watchouts
- No published pricing
- No license number published on the website
2
Dock Medics of Florida
Publishes two license numbers including an electrical contractor license, which matters because boat lift motor and control work is electrical work. One of the few contractors in this set to name emergency boat lift repair as a distinct service rather than folding it into general repair.
Strengths
- Publishes both building and electrical contractor licenses
- Named emergency boat lift repair capability
- Electrical license covers lift motor and control work
Watchouts
- No published pricing
- Service area stated only as Northeast Florida, without corridor detail
3
Shore Builders
Publishes two contractor license numbers, but is headquartered in Newberry near Gainesville rather than in the Jacksonville market it advertises into. This is a service area claim rather than a local presence, which is worth confirming before scheduling work that may need a return visit.
Strengths
- Publishes building and general contractor licenses
- Holds both residential and commercial credentials
Watchouts
- Headquartered outside the Jacksonville market
- No published pricing
- No corridor level service detail
4
Kenyon Marine Construction
Describes four generations of marine construction experience in the Jacksonville market. Detail for this entry comes from public search and directory evidence rather than direct verification, so treat the credential claims as unconfirmed until checked.
Strengths
- Long stated family operating history in Jacksonville
- New construction and design capability
Watchouts
- Detail not directly verified for this review
- No published pricing or license number found
5
JP Dock Building and Repairs
Positions specifically around boat lift installation for Jacksonville and surrounding Northeast Florida, which matches the strongest recorded search demand in this market. Offers free estimates. Detail comes from public search evidence rather than direct verification.
Strengths
- Boat lift installation is the stated primary service
- Free estimates offered
Watchouts
- Detail not directly verified for this review
- No published license number found
6
Coastal Marine Group
Names the St. Johns River and the Intracoastal Waterway specifically rather than claiming a generic Jacksonville service area, which is the right grain for this market. Trades under a keyword domain rather than the company name, which splits its entity signals across two identities.
Strengths
- Names the two waterways that define the market
- Custom dock and seawall capability
Watchouts
- Company name and domain do not match
- License number not published
- Detail not directly verified
7
First Coast Dock Repair
Publishes separate service pages for dock repair, boat lift installation, boat lift repair, seawall and bulkhead work in each market it covers, which is unusually complete page-level coverage for this category. That page depth is a visibility signal, not evidence about workmanship.
Strengths
- Separate published page for each service and market
- Coverage across all four markets compared here
Watchouts
- No published license number
- No published pricing
- Page depth does not by itself evidence completed work
Buyer Checklist
- Look up the license number with the state before you sign Two contractors in this set publish license numbers. Florida contractor licenses are publicly searchable, which makes this the only credential here a buyer can verify independently.
- Confirm an electrical license covers the lift motor work Boat lift motors and controls are electrical work. Only one contractor in this set publishes an electrical contractor license alongside its building license.
- Ask which corridor the contractor has actually worked A Northeast Florida service claim covers six counties. Ask for a job on water like yours, not just nearby.
- Check whether the company is based where it advertises At least one contractor here is headquartered outside the market it advertises into, which matters for warranty visits and callbacks.
- Separate installation pricing from repair pricing No contractor in this set publishes either. Get both in writing before work starts.
- Confirm permitting responsibility in writing Duval, St Johns, and Flagler counties run separate processes, and historic district frontage runs slower again.
- Ask whether the quote survives the onsite inspection Two contractors here quote only after an inspection. A number given before one is not yet a price.
FAQ
What does dock or boat lift work cost in Jacksonville?
No contractor reviewed for this market publishes pricing. Two quote only after an onsite inspection, and one offers free estimates. Marine work is priced on water depth, access, structure condition, and permitting, so a published rate would be close to meaningless. The practical consequence is that a buyer cannot shortlist on price and has to schedule inspections with several contractors instead.
How do I verify a marine contractor in Florida?
Ask for the license number and check it against the state licensing record. In this set, Dock Medics of Florida publishes CBC1267563 and EC13010192, and Shore Builders publishes CBC1258492 and CGC1538875. The remaining contractors state that they are licensed without publishing a number. A license number is the only credential in this comparison a buyer can independently confirm.
Why does an electrical license matter for a boat lift?
A boat lift is a motor, a control box, and wiring in a wet environment. That is electrical work, and in Florida it falls under a separate license from general or building contracting. A contractor holding only a building license may be subcontracting the electrical portion, which is normal but worth confirming before work starts.
Does a Northeast Florida service area include my address?
Not necessarily. Northeast Florida spans Duval, Clay, Putnam, St Johns, Flagler, and Nassau counties, and a contractor claiming the region may in practice work a much smaller radius. Ashcraft Marine Construction is the only contractor in this set that names individual corridors and counties. With everyone else, ask for a recent job on comparable water before assuming coverage.
How were these contractors selected?
This set covers marine contractors that are publicly discoverable for Jacksonville dock, boat lift, seawall and bulkhead searches as of September 2026. Some entries were verified directly against the contractor website and some rely on public search and directory evidence, which is stated in each entry. Contractors that could not be attributed to this market at all were left out rather than listed with gaps.
Is this a ranking of the best contractors?
No. This compares what each contractor publishes, including licenses, stated service areas, and service coverage. It does not assess workmanship, and nothing here should be read as a guarantee. Verify license, insurance, and permitting responsibility before hiring anyone.
Methodology: Contractors were identified from public marine construction search results and directory listings for this market in September 2026. Entries marked as directly verified were checked against the contractor website for license numbers, founding year, stated service areas, and published pricing. Entries relying on public search and directory evidence are identified as such in their notes. Published license numbers are reproduced as stated and should be confirmed against the Florida state licensing record before hiring. Absence of published pricing is recorded as a fact about disclosure and is not a judgment about workmanship.
