Marine Construction Services in Naples, FL
Kalvin & Calvin Marine Construction has provided full-service marine construction services in Naples, FL for more than 40 years. As a family-owned firm rooted in Collier County, we build, inspect, and repair seawalls, docks, and boat lifts for waterfront homeowners, condominium associations, marinas, and commercial clients throughout Southwest Florida.
From initial consultation through permitting and final walkthrough, our licensed and insured team manages every stage of your project with the same attention to craftsmanship and communication that has defined our work since the mid-1970s. Below is an overview of the marine construction services we offer throughout Naples, Marco Island, and the surrounding Collier County waterfront.
Dock Construction & Installation
A well-built dock extends your living space onto the water and gives you safe, reliable access to your boat every day of the year. We design and install custom docks using wood, cellular PVC, and advanced composite decking, selecting materials that match your property's aesthetic while standing up to the salt air and heavy weather of Southwest Florida.
Every project begins with a detailed property evaluation, and our design team works with you to create a dock that fits your lifestyle, budget, and permit requirements. We handle the drawings and paperwork needed to keep your project moving through the local permitting process, and we use premium-grade pilings, fasteners, and hardware proven to withstand the Southwest Florida climate, so your new dock maintains its integrity and enhances your property for years to come.
Residential Seawalls
Homeowners throughout Naples rely on their seawall to protect their property from tidal erosion, storm surge, and shifting soil along the shoreline. We design and build new residential seawalls using concrete and vinyl construction methods suited to your property's soil conditions and exposure.
If your existing seawall is showing signs of wear, such as cracking, leaning, or soil loss behind the panels, we can recommend the right repair or replacement approach to restore its structural integrity. Every residential seawall project is built to hold up against the demands of the local coastal environment while complementing the rest of your waterfront property.
Commercial Seawalls
Marinas, condominium associations, restaurants, and other commercial properties along the Naples waterfront depend on their seawalls to protect significant infrastructure and investment. We have decades of experience with large-scale commercial seawall construction, and we understand the coordination, permitting, and engineering considerations that come with multi-unit and commercial properties.
Our team works to minimize disruption to tenants, guests, and daily operations while delivering a seawall built for long-term coastal durability.
Seawall Inspection
Not sure how much life is left in your seawall? Our seawall inspection services help you understand the current condition of your structure and plan ahead before a small issue becomes an expensive emergency. We evaluate the panels, cap, tie-backs, and soil conditions behind your seawall to determine its remaining service life, and we provide straightforward recommendations, whether that means monitoring, targeted repair, or full replacement.
Regular seawall inspection is one of the most cost-effective ways to protect your waterfront investment over time.
Boat Lift Installation
A properly sized and installed boat lift protects your vessel from wave action, tidal changes, and hull damage while making it easier to get on and off the water. We design and install boat lifts engineered for the specific conditions of your dock, taking into account water depth, tidal range, and the size and weight of your boat.
Our installations are built to hold up to the Southwest Florida climate and to keep your boat safely out of the water between trips.
Boat Lift Inspections
Boat lifts see near-constant exposure to sun, salt water, and moving parts under load, and regular inspection helps catch wear before it leads to lift failure or boat damage. Our boat lift inspections cover the cables, motor, gears, pilings, and structural components of your lift, and we identify any repairs needed to keep it operating safely and smoothly.
Whether your lift is showing signs of slow operation, unusual noise, or visible wear, we can evaluate it and recommend next steps.
Our Marine Construction Process
Every project at Kalvin & Calvin Marine Construction starts with a free, on-site evaluation of your property. From there, our design team creates a plan tailored to your goals, and we manage permitting with local and state authorities to keep your project moving without delays. Once construction begins, we commit to timely communication at the frequency that works for you, so you always know where your project stands.
We treat every dock, seawall, and boat lift as if it were our own, and we do not consider a project finished until the result meets our standards and yours.

Frequently Asked Questions
How much does professional marine construction cost in Naples, FL?
Pricing depends on the service. Seawall work generally runs $400 to $900 per linear foot, new docks range from $25,000 to $75,000 for most residential projects, and boat lifts run roughly $8,000 to $50,000 based on capacity and dock configuration. We provide a free estimate tailored to your property.
How long do dock, seawall, and boat lift projects typically take to complete?
Most residential projects take a few weeks to a few months, depending on permitting timelines and project scope. Seawall and dock repairs are usually quicker than new construction, and we'll give you a realistic timeline before work begins.
Do you offer dredging services in addition to docks and seawalls?
Yes. Sediment buildup around docks and seawalls can restrict boat access over time, so we offer dredging services to restore usability while following environmental best practices required in Southwest Florida waterways.
What's the difference between residential and commercial marine construction?
Residential projects typically involve a single dock, seawall, or boat lift built to a homeowner's specifications. Commercial projects, such as marinas, condominiums, and restaurants, involve larger-scale construction with more complex engineering, permitting, and coordination to minimize disruption to tenants and guests.
Do I need a permit for a boat lift, dock, or seawall in Collier County?
In most cases, yes. New construction, repairs, and replacements for docks, seawalls, and boat lifts typically require permits from Collier County or the City of Naples, and some projects also need approval from the Florida Department of Environmental Protection or the U.S. Army Corps of Engineers. We manage this process on your behalf.
How often should I schedule a seawall or boat lift inspection?
We recommend a professional inspection at least once a year for both seawalls and boat lifts. Regular inspections catch cracking, corrosion, or worn hardware early, before minor issues turn into costly repairs or emergency replacements.
Can you help with erosion control and shoreline stabilization?
Yes. We offer erosion control solutions, including riprap installation and bank stabilization, to protect shorelines that don't have a full seawall or to reinforce areas prone to erosion.
Are you licensed and insured for marine construction in Florida?
Yes. Kalvin & Calvin Marine Construction is licensed and insured, and our team has served Collier County's waterfront since 1982.
Do you offer free estimates for seawall, dock, and boat lift projects?
Yes. Every project starts with a free, no-obligation, on-site evaluation so we can give you an accurate estimate based on your property's specific conditions.
What time of year is best to schedule marine construction work in Southwest Florida?
Many homeowners schedule work during the dry season, roughly November through May, to avoid hurricane season delays and higher water levels. That said, we work with clients year-round and can advise on timing based on your specific project.
