Duval County · Northeast Florida
Jacksonville Dock Builder designs, builds and repairs docks, boat lifts, floating platforms and waterfront decks throughout Duval County — on the St. Johns River main stem, along the Intracoastal Waterway and up the tidal creeks that feed both.

Local water
No two shorelines in Northeast Florida behave the same way. These are the conditions we design around here.
Tidal all the way through the city and well upstream of it. Salinity shifts with the season and with how much rain the upper basin has had, which affects both marine borer activity and how aggressively hardware corrodes. Depth off the bank varies enormously between the deep channel reaches near downtown and the wide shallow flats further south.
Running north–south behind the beaches, with constant commercial and recreational traffic. Wake is a design load here, not an afterthought — terminal platforms, lift placement and fender detailing all need to account for it.
Mandarin and Durbin-area creeks with soft bottoms, substantial tidal swing and shallow water at low tide. Reaching workable depth frequently means a long walkway, and floating sections are popular for small craft.
Protected water with established waterfront neighbourhoods and plenty of older structures now reaching the end of their service life. Replacement and piling work is common here.
North and east-side tidal tributaries with marsh edges, variable bottom conditions and good shelter from the main river's wind fetch.
A winding tidal creek on the south-east side with narrow reaches, meaning careful attention to how far a structure projects and to navigation clearance for neighbours.
Duval County waterfront is not one condition. The St. Johns changes character along its length, and the creeks feeding it behave differently again. A dock that is exactly right in Ortega would be the wrong structure at Julington Creek, and neither would suit an Intracoastal lot behind the beaches.
Near downtown and through the deeper reaches, the bottom drops away reasonably close to shore and salinity runs high enough that marine borers are a constant. South of there the river widens into broad, shallow water, where the controlling problem is reaching enough depth at low tide and where sustained wind across miles of open water builds genuine chop. Up the tidal creeks — Julington, Durbin, Pottsburg, Trout — the water is sheltered but shallow and the bottoms are soft, so walkways get long and pilings need to go deep to find holding.
Along the Intracoastal the dominant load is not weather at all. It is wake, arriving all day, from both directions.
The first thing we do on any Jacksonville site visit is sound the water depth at low tide and look at what the bottom is made of. Those two measurements drive almost everything else: how long the structure needs to be, how many pilings it takes, how deep they have to be driven, whether a lift will work at your depth, and whether a floating section makes more sense than extending further out.
The second thing we look at is where the weather and wake come from. On an exposed main-river lot that determines which side the terminal platform should sit on and which way a lift should face. On a creek lot it matters far less, and the money is better spent on length.
A great deal of what we do in Jacksonville is replacing structures built decades ago in Ortega, Avondale, San Marco, Beauclerc and along the Arlington shoreline. Those docks were generally well built for their time, but they were framed for lighter boats, lighter use and before current expectations about storm loading, and the pilings are now at an age where embedment and internal condition need honest assessment.
If you are in that position, the useful first step is an inspection rather than a quote. We will tell you whether you are looking at repair, replacement or several more good years, and we would rather give you the first answer than sell you the second.
Dock and marine work in Duval County typically involves a City of Jacksonville building permit alongside state environmental review through the Florida Department of Environmental Protection or the St. Johns River Water Management District, and federal authorisation from the U.S. Army Corps of Engineers Jacksonville District. Some small private residential docks qualify for streamlined exemptions, but whether yours does depends on size, waterway classification and what is on the bottom beneath the proposed structure. We prepare and track the submittals your project needs.
Requirements change. Confirm current rules with the Florida Department of Environmental Protection, the St. Johns River Water Management District and the U.S. Army Corps of Engineers Jacksonville District, along with your local building department.
Jacksonville answers
It varies more than most owners expect, because the timeline depends on which agencies are involved rather than on how big the dock is. A straightforward private residential structure that qualifies for a streamlined path moves considerably faster than one requiring full environmental review. We give you a realistic range once we know the waterway, the parcel and the proposed footprint, and we will not quote you a schedule we cannot stand behind.
Entirely dependent on where you are. Near the deep channel reaches the bottom falls away quickly and a relatively short structure reaches usable water. Across the broad southern stretches of the river the shelf can run a long way out at shallow depth. The only way to answer it for your property is to sound the depth at low tide, which is the first thing we do on a site visit.
You can leave it in, but the water here grows things quickly, particularly through the warm months. Bottom growth, running gear corrosion and bottom paint consumption all accelerate when a hull stays submerged. Most owners who use their boat regularly find a lift pays for itself over the equipment's life, quite apart from keeping the hull off the bottom at low tide.
Throughout Duval County — Ortega, Mandarin, San Marco, Riverside and Avondale, Arlington, Beauclerc, Julington Creek, Queens Harbour, Fort Caroline and the Intracoastal corridor behind the beaches. If you have water frontage in Jacksonville, we can get to it.
Yes. After a storm we assess what is salvageable, document the damage and provide a detailed itemised scope you can use with your insurer. What is covered is between you and your policy, but a specific, well-documented scope makes that conversation far simpler.
