A floating dock is a decade-plus investment. Conducting a thorough dock warranty comparison is one of the few pieces of the purchase decision you can evaluate objectively with hard numbers and it’s also where most buyers simply nod and sign without reading the fine print. Don’t. The real-world difference between an 8-year and a 20-year polyethylene structural guarantee on a $15,000 system is immense, which is why a deep-dive dock warranty comparison is essential before making an investment.
This detailed dock warranty comparison evaluates the floating dock coverages offered by the major brands sold in Southwest Florida Wave Armor, EZ Dock, Connect-A-Dock, Candock, and a few regional players so you can make an informed, side-by-side decision before you buy.
Why a Dock Warranty Comparison Matters for SW Florida Homeowners
A floating dock lives in the single harshest environment a residential product can face: direct sun, saltwater, humidity, wave motion, and occasional hurricane exposure. Unlike almost any other purchase for your home, you can’t keep it indoors, you can’t service it often, and replacement is expensive and disruptive. The warranty is your hedge against all of that.
When analyzing a comprehensive dock warranty comparison, two distinct dimensions matter: how many years of coverage you get, and what is actually covered. A 20-year coverage period plagued with 400 exclusions isn’t worth more than an 8-year contract with zero loopholes. This dock warranty comparison serves as your shield against unexpected failure costs down the line. Here is how the major brands stack up against each other.

Fine Print Insights From Our Dock Warranty Comparison
The headline number of years on a brochure looks great, but the legal body text is what actually determines your protection. No dock warranty comparison is complete without uncovering the critical hidden clauses buried deep inside local contracts:
Is the warranty prorated or full-replacement?
A full-replacement warranty means if a defect occurs in year 12 of a 20-year warranty, you get a new section. A prorated warranty means you get a percentage of a new section based on how much life it had left and in year 12 of a 20-year prorated warranty, that might be 40% of the replacement cost. Wave Armor offers 5 years full replacement then prorates; EZ Dock offers 3 years full replacement then prorates. Candock is similar to Wave Armor. Our dock warranty comparison shows that Wave Armor offers 5 years of full replacement before it prorates; EZ Dock offers 3 years of full replacement.
Is the warranty transferable?
If you sell your home in year 5, does the new owner still have the warranty?This is a key inflection point in our dock warranty comparison. Wave Armor and Candock transfer. EZ Dock and Connect-A-Dock do not. For real estate appeal in the Florida waterfront market, transferability is a meaningful feature; an aging dock with no warranty is a buyer negotiation lever.
Is saltwater use covered without any caveats?
Read this section carefully. Some manufacturers cover “normal residential use” but embed restrictive language that minimizes coverage in high-salinity zones. Our structural dock warranty comparison notes that Wave Armor explicitly covers saltwater as a standard environment. EZ Dock’s saltwater coverage requires specific registration parameters at installation. Connect-A-Dock excludes UV degradation after year 3 which, in the brutal Florida sun, is effectively the primary failure mode you want covered.
What about hurricane damage?
Virtually no manufacturer covers “Acts of God.” Hurricane damage is entirely excluded across every single brand in this dock warranty comparison. That makes your marine installation workmanship warranty and your homeowner’s insurance policy your real lines of defense. MacDuff Marine’s workmanship warranty covers structural connection failures caused by improper assembly, while your insurance covers storm-driven forces.
How does hardware warranty compare to section warranty?
Polyethylene sections almost never fail. First it’s the hardware (bolts, couplers, hinges) that’s the typical failure point in a 15-year-old dock. A 20-year section warranty paired with a 2-year hardware warranty isn’t as good as a 20-year section warranty paired with a 5-year hardware warranty. Wave Armor and Candock offer 5-year hardware; EZ Dock offers 2-year; Connect-A-Dock offers 1-year.
Final Review: Who Wins the Dock Warranty Comparison?
Ranking the brands purely on warranty coverage depth for Florida saltwater residential use:
- Wave Armor: 20-year section + 5-year hardware + transferable + saltwater included. Best overall.
- Candock: Essentially tied with Wave Armor on terms; slightly less dealer coverage in SW Florida.
- Jet Dock: 10-year section + 5-year hardware + transferable. Strong mid-tier.
- Connect-A-Dock: 10-year but UV exclusion after year 3 is a real problem in Florida.
- EZ Dock: 8-year with saltwater caveats and non-transferable. Weakest of the major brands on paper.
Why Expert Local Installation Matters Alongside Your Warranty
A dock warranty comparison is only useful if a claim is processed cleanly when an issue arises. That is often determined just as much by your local marine contractor as it is by the manufacturing brand. By choosing a factory-authorized dealer like MacDuff Marine, your claims are handled directly by our local team meaning no mailing in complex forms or fighting with a distant corporate service office.
Additionally, remember that the manufacturer warranty only protects the physical product; your contractor’s workmanship warranty covers the actual construction. MacDuff Marine provides a separate installation workmanship warranty in writing on every single residential dock job to complement your manufacturer protection.
Frequently Asked Questions
Does the dock warranty cover normal wear and tear?
No major floating dock warranty covers normal wear and tear. What’s covered is manufacturing defects, structural failure, and material degradation beyond what’s expected from normal use. Surface scuffs, fading within the expected range, and cosmetic aging are not warranty items.
If I install the dock myself, is the warranty still valid?
Often no. Most floating dock manufacturers require installation by a factory-authorized dealer to maintain full warranty coverage. Self-installs may void certain warranty categories or reduce the coverage period. Check the specific terms before attempting DIY.
What voids a floating dock warranty?
Common voiders: exceeding rated load capacity, commercial use on a residential warranty, modifications or repairs by non-authorized parties, and in some cases saltwater exposure without registration. Acts of God (hurricane, lightning, flood) are excluded across all brands.
Does the warranty cover the installation itself?
No. The manufacturer warranty covers the product; your installer’s workmanship warranty covers the installation. MacDuff Marine provides a separate installation workmanship warranty in writing on every job asking for the same from any installer you consider.
